GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
GNU LIBRARY GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which
contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Library
General Public License (also called "this License"). Each licensee is
addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also compile or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
d) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Library General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Library General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Library General Public License for more details.
You should have received a copy of the GNU Library General Public
License along with this library; if not, write to the Free
Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA.
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

# gst-build
GStreamer [meson](http://mesonbuild.com/) based repositories aggregrator.
Check out this module and run meson on it, and it will git clone the other
GStreamer modules as [meson subprojects](http://mesonbuild.com/Subprojects.html)
and build everything in one go. Once that is done you can switch into an
development environment which allows you to easily develop and test the latest
version of GStreamer without the need to install anything or touch an existing
GStreamer system installation.
## Getting started
### Install git and python 3.5+
If you're on Linux, you probably already have these. On macOS, you can use the
[official Python installer](https://www.python.org/downloads/mac-osx/).
You can find [instructions for Windows below](#windows-prerequisites-setup).
### Install meson and ninja
Meson 0.52 or newer is required.
For cross-compilation Meson 0.54 or newer is required.
On Linux and macOS you can get meson through your package manager or using:
$ pip3 install --user meson
This will install meson into `~/.local/bin` which may or may not be included
automatically in your PATH by default.
You should get `ninja` using your package manager or download the [official
release](https://github.com/ninja-build/ninja/releases) and put the `ninja`
binary in your PATH.
You can find [instructions for Windows below](#windows-prerequisites-setup).
### Build GStreamer and its modules
You can get all GStreamer built running:
```
meson builddir
ninja -C builddir
```
This will automatically create the `build` directory and build everything
inside it.
NOTE: On Windows, you *must* run this from [inside the Visual Studio command
prompt](#running-meson-on-windows) of the appropriate architecture and version.
### External dependencies
All mandatory dependencies of GStreamer are included as [meson subprojects](https://mesonbuild.com/Subprojects.html):
libintl, zlib, libffi, glib. Some optional dependencies are also included as
subprojects, such as ffmpeg, x264, json-glib, graphene, openh264, orc, etc.
Mandatory dependencies will be automatically built if meson cannot find them on
your system using pkg-config. The same is true for optional dependencies that
are included as subprojects. You can find a full list by looking at the
`subprojects` directory.
Plugins that need optional dependencies that aren't included can only be built
if they are provided by the system. Instructions on how to build some common
ones such as Qt5/QML are listed below. If you do not know how to provide an
optional dependency needed by a plugin, you should use [Cerbero](https://gitlab.freedesktop.org/gstreamer/cerbero/#description)
which handles this for you automatically.
Plugins will be automatically enabled if possible, but you can ensure that
a particular plugin (especially if it has external dependencies) is built by
enabling the gstreamer repository that ships it and the plugin inside it. For
example, to enable the Qt5 plugin in the gst-plugins-good repository, you need
to run meson as follows:
```
meson -Dgood=enabled -Dgst-plugins-good:qt5=enabled builddir
```
This will cause Meson to error out if the plugin could not be enabled. You can
also flip the default and disable all plugins except those explicitly enabled
like so:
```
meson -Dauto_features=disabled -Dgstreamer:tools=enabled -Dbad=enabled -Dgst-plugins-bad:openh264=enabled
```
This will disable all optional features and then enable the `openh264` plugin
and the tools that ship with the core gstreamer repository: `gst-inspect-1.0`,
`gst-launch-1.0`, etc. As usual, you can change these values on a builddir that
has already been setup with `meson configure -Doption=value`.
### Building the Qt5 QML plugin
If `qmake` is not in `PATH` and pkgconfig files are not available, you can
point the `QMAKE` env var to the Qt5 installation of your choosing before
running `meson` as shown above.
The plugin will be automatically enabled if possible, but you can ensure that
it is built by passing `-Dgood=enabled -Dgst-plugins-good:qt5=enabled` to `meson`.
### Building the Intel MSDK plugin
On Linux, you need to have development files for `libmfx` installed. On
Windows, if you have the [Intel Media SDK](https://software.intel.com/en-us/media-sdk),
it will set the `INTELMEDIASDKROOT` environment variable, which will be used by
the build files to find `libmfx`.
The plugin will be automatically enabled if possible, but you can ensure it by
passing `-Dbad=enabled -Dgst-plugins-bad:msdk=enabled` to `meson`.
### Static build
Since *1.18.0* when doing a static build using `--default-library=static`, a
shared library `gstreamer-full-1.0` will be produced and includes all enabled
GStreamer plugins and libraries. A list of libraries that needs to be exposed in
`gstreamer-full-1.0` ABI can be set using `gst-full-libraries` option. glib-2.0,
gobject-2.0 and gstreamer-1.0 are always included.
```
meson --default-library=static -Dgst-full-libraries=app,video builddir
```
GStreamer *1.18* requires applications using gstreamer-full-1.0 to initialize
static plugins by calling `gst_init_static_plugins()` after `gst_init()`. That
function is defined in `gst/gstinitstaticplugins.h` header file.
Since *1.20.0* `gst_init_static_plugins()` is called automatically by
`gst_init()` and applications must not call it manually any more. The header
file has been removed from public API.
One can use the `gst-full-version-script` option to pass a
[version script](https://www.gnu.org/software/gnulib/manual/html_node/LD-Version-Scripts.html)
to the linker. This can be used to control the exact symbols that are exported by
the gstreamer-full library, allowing the linker to garbage collect unused code
and so reduce the total library size. A default script `gstreamer-full-default.map`
declares only glib/gstreamer symbols as public.
One can use the `gst-full-plugins` option to pass a list of plugins to be registered
in the gstreamer-full library. The default value is '*' which means that all the plugins selected
during the build process will be registered statically. An empty value will prevent any plugins to
be registered.
One can select a specific set of features with `gst-full-elements`, `gst-full-typefind-functions`, `gst-full-device-providers` or `gst-full-dynamic-types` to select specific feature from a plugin.
When a feature has been listed in one of those options, the other features from its plugin will no longer be automatically included, even if the plugin is listed in `gst-full-plugins`.
The user must insure that all selected plugins and features (element, typefind, etc.) have been
enabled during the build configuration.
To register features, the syntax is the following:
plugins are separated by ';' and features from a plugin starts after ':' and are ',' separated.
As an example:
* `-Dgst-full-plugins=coreelements;playback;typefindfunctions;alsa;pbtypes`: enable only `coreelements`, `playback`, `typefindfunctions`, `alsa`, `pbtypes` plugins.
* `-Dgst-full-elements=coreelements:filesrc,fakesink,identity;alsa:alsasrc`: enable only `filesrc`, `identity` and `fakesink` elements from `coreelements` and `alsasrc` element from `alsa` plugin.
* `-Dgst-full-typefind-functions=typefindfunctions:wav,flv`: enable only typefind func `wav` and `flv` from `typefindfunctions`
* `-Dgst-full-device-providers=alsa:alsadeviceprovider`: enable `alsadeviceprovider` from `alsa`.
* `-Dgst-full-dynamic-types=pbtypes:video_multiview_flagset`: enable `video_multiview_flagset` from `pbtypes
All features from the `playback` plugin will be enabled and the other plugins will be restricted to the specific features requested.
All the selected features will be registered into a dedicated `NULL` plugin name.
This will cause the features/plugins that are not registered to not be included in the final gstreamer-full library.
This is an experimental feature, backward uncompatible changes could still be
made in the future.
# Development environment
## Development environment target
gst-build also contains a special `devenv` target that lets you enter an
development environment where you will be able to work on GStreamer
easily. You can get into that environment running:
```
ninja -C builddir devenv
```
If your operating system handles symlinks, built modules source code will be
available at the root of `gst-build/` for example GStreamer core will be in
`gstreamer/`. Otherwise they will be present in `subprojects/`. You can simply
hack in there and to rebuild you just need to rerun `ninja -C builddir`.
NOTE: In the development environment, a fully usable prefix is also configured
in `gst-build/prefix` where you can install any extra dependency/project.
An external script can be run in development environment with:
```
./gst-env.py external_script.sh
```
## Update git subprojects
We added a special `update` target to update subprojects (it uses `git pull
--rebase` meaning you should always make sure the branches you work on are
following the right upstream branch, you can set it with `git branch
--set-upstream-to origin/master` if you are working on `gst-build` master
branch).
Update all GStreamer modules and rebuild:
```
ninja -C builddir update
```
Update all GStreamer modules without rebuilding:
```
ninja -C builddir git-update
```
## Custom subprojects
We also added a meson option, `custom_subprojects`, that allows the user
to provide a comma-separated list of subprojects that should be built
alongside the default ones.
To use it:
```
cd subprojects
git clone my_subproject
cd ../build
rm -rf * && meson .. -Dcustom_subprojects=my_subproject
ninja
```
## Run tests
You can easily run the test of all the components:
```
meson test -C build
```
To list all available tests:
```
meson test -C builddir --list
```
To run all the tests of a specific component:
```
meson test -C builddir --suite gst-plugins-base
```
Or to run a specific test file:
```
meson test -C builddir --suite gstreamer gst_gstbuffer
```
Run a specific test from a specific test file:
```
GST_CHECKS=test_subbuffer meson test -C builddir --suite gstreamer gst_gstbuffer
```
## Optional Installation
`gst-build` has been created primarily for [development usage](#development-environment-target),
but you can also install everything that is built into a predetermined prefix like so:
```
meson --prefix=/path/to/install/prefix builddir
ninja -C builddir
meson install -C builddir
```
Note that the installed files have `RPATH` stripped, so you will need to set
`LD_LIBRARY_PATH`, `DYLD_LIBRARY_PATH`, or `PATH` as appropriate for your
platform for things to work.
## Checkout another branch using worktrees
If you need to have several versions of GStreamer coexisting (eg. `master` and `1.16`),
you can use the `gst-worktree.py` script provided by `gst-build`. It allows you
to create a new `gst-build` environment with new checkout of all the GStreamer modules as
[git worktrees](https://git-scm.com/docs/git-worktree).
For example to get a fresh checkout of `gst-1.16` from a `gst-build` repository
that is checked out at master, you can run:
```
./gst-worktree.py add gst-build-1.16 origin/1.16
```
This will create a new ``gst-build-1.16`` directory pointing to the given branch `1.16`
for all the subprojects (gstreamer, gst-plugins-base, etc.)
## Add information about GStreamer development environment in your prompt line
### Bash prompt
We automatically handle `bash` and set `$PS1` accordingly.
If the automatic `$PS1` override is not desired (maybe you have a fancy custom prompt), set the `$GST_BUILD_DISABLE_PS1_OVERRIDE` environment variable to `TRUE` and use `$GST_ENV` when setting the custom prompt, for example with a snippet like the following:
```bash
...
if [[ -n "${GST_ENV-}" ]];
then
PS1+="[ ${GST_ENV} ]"
fi
...
```
### Using powerline
In your powerline theme configuration file (by default in
`{POWERLINE INSTALLATION DIR}/config_files/themes/shell/default.json`)
you should add a new environment segment as follow:
```
{
"function": "powerline.segments.common.env.environment",
"args": { "variable": "GST_ENV" },
"priority": 50
},
```
## Windows Prerequisites Setup
On Windows, some of the components may require special care.
### Git for Windows
Use the [Git for Windows](https://gitforwindows.org/) installer. It will
install a `bash` prompt with basic shell utils and up-to-date git binaries.
During installation, when prompted about `PATH`, you should select the
following option:
![Select "Git from the command line and also from 3rd-party software"](/data/images/git-installer-PATH.png)
### Python 3.5+ on Windows
Use the [official Python installer](https://www.python.org/downloads/windows/).
You must ensure that Python is installed into `PATH`:
![Enable Add Python to PATH, then click Customize Installation](/data/images/py-installer-page1.png)
You may also want to customize the installation and install it into
a system-wide location such as `C:\PythonXY`, but this is not required.
### Ninja on Windows
The easiest way to install Ninja on Windows is with `pip3`, which will download
the compiled binary and place it into the `Scripts` directory inside your
Python installation:
```
pip3 install ninja
```
You can also download the [official release](https://github.com/ninja-build/ninja/releases)
and place it into `PATH`.
### Meson on Windows
**IMPORTANT**: Do not use the Meson MSI installer since it is experimental and known to not
work with `gst-build`.
You can use `pip3` to install Meson, same as Ninja above:
```
pip3 install meson
```
Note that Meson is written entirely in Python, so you can also run it as-is
from the [git repository](https://github.com/mesonbuild/meson/) if you want to
use the latest master branch for some reason.
**ARM64 native only**: You might need
[native upstream ARM64 support fix](https://github.com/mesonbuild/meson/pull/7432)
which is expected to be a part of Meson 0.55.1.
If your Meson package version which was installed via `pip3` is lower than 0.55.1,
then you need to use [the latest master branch](https://github.com/mesonbuild/meson/).
### Running Meson on Windows
At present, to build with Visual Studio, you need to run Meson from inside the
VS 2019 command prompt. Press `Start`, and search for `VS 2019`, and click on
`x64 Native Tools Command Prompt for VS 2019`, or a prompt named similar to
that:
![x64 Native Tools Command Prompt for VS 2019](/data/images/vs-2019-dev-prompt.png)
**ARM64 native only**: Since Visual Studio might not install dedicated command
prompt for native ARM64 build, you might need to run `vcvarsx86_arm64.bat` on CMD.
Please refer to [this document](https://docs.microsoft.com/en-us/cpp/build/building-on-the-command-line?view=vs-2019#developer_command_file_locations)
### Setup a mingw/wine based development environment on linux
#### Install wine and mingw
##### On fedora x64
``` sh
sudo dnf install mingw64-gcc mingw64-gcc-c++ mingw64-pkg-config mingw64-winpthreads wine
```
FIXME: Figure out what needs to be installed on other distros
#### Get meson from git
This simplifies the process and allows us to use the cross files
defined in meson itself.
``` sh
git clone https://github.com/mesonbuild/meson.git
```
#### Build and install
```
BUILDDIR=$PWD/winebuild/
export WINEPREFIX=$BUILDDIR/wine-prefix/ && mkdir -p $WINEPREFIX
# Setting the prefix is mandatory as it is used to setup symlinks during uninstalled development
meson/meson.py $BUILDDIR --cross-file meson/cross/linux-mingw-w64-64bit.txt -Dgst-plugins-bad:vulkan=disabled -Dorc:gtk_doc=disabled --prefix=$BUILDDIR/wininstall/ -Djson-glib:gtk_doc=disabled
meson/meson.py install -C $BUILDDIR/
```
> __NOTE__: You should use `meson install -C $BUILDDIR` each time you make a change
> instead of the usual `ninja -C build` as the environment is not uninstalled.
#### The development environment
You can get into the development environment the usual way:
```
ninja -C $BUILDDIR/ devenv
```
Alternatively, if you'd rather not start a shell in your workflow, you
can mutate the current environment into a suitable state like so:
```
gst-env.py --only-environment
```
This will print output suitable for an sh-compatible `eval` function,
just like `ssh-agent -s`.
After setting up [binfmt] to use wine for windows binaries,
you can run GStreamer tools under wine by running:
```
gst-launch-1.0.exe videotestsrc ! glimagesink
```
[binfmt]: http://man7.org/linux/man-pages/man5/binfmt.d.5.html

# Cross compiling GStreamer with gst-build
GStreamer can be cross compiled for various platforms using gst-build. However,
only dependencies that are ported to the Meson build system will be built. It is
recommended to use Cerbero to cross compile GStreamer when other external
dependencies are required.
Once the toolchain is installed and a Meson cross file is created, to build
GStreamer simply run for example: `meson --cross-file data/cross-files/mingw_w64_x86-64.txt builddir`.
## Android
Requires Android API level >= 28, previous versions are missing *iconv* dependency.
- Download and extract the [NDK](https://developer.android.com/ndk/)
- Create a Meson cross file, you can use `android_arm64_api28.txt` as example
and change CPU architectures and toolchain path using the prebuilt toolchains
from the NDK.
Notes:
- On fedora the Android NDK requires the `ncurses-compat-libs` package.
## Windows
GStreamer can be cross compiled for Windows using mingw packaged in most
distribution.
The Meson cross file `mingw_w64_x86-64.txt` can be used when targeting amd64
architecture, or adapted for i686 arch.
### Fedora
- Install the toolchain packages: `mingw64-gcc`, `mingw64-gcc-c++`. Fedora
provides many other optional dependencies that could be installed as well.
For example: `mingw64-gettext`, `mingw64-libffi`, `mingw64-zlib`.
### Ubuntu
- Install the toolchain package: `gcc-mingw-w64`.

## How to generate binaries and update build files
1. Download the latest bison source tarball
1. Extract, then build it with --prefix=/
1. Install into some dir using `DESTDIR`
1. Delete all files except the following subdirs: `bin` `lib` `share/bison` `share/aclocal`
1. Rename installdir to `bison-$version-macos-$arch` where `$arch` follows Meson's CPU families list:
https://mesonbuild.com/Reference-tables.html#cpu-families
1. `tar -cvjf bison-$version-macos-$arch.tar.bz2 bison-$version-macos-$arch/`
1. Fetch sha256sum: `shasum -256 bison-$version-macos-$arch.tar.bz2`
1. Update sha256sum in `meson.build`
1. Update `project()` version in `meson.build`
That's it!
