gst-launch
|

================
|
||||
|
||||
This is a tool that will construct pipelines based on a command-line
|

@ -8,125 +8,125 @@ feedback pipelines are the most complex.
|
|||
|
||||
A simple commandline looks like:
|
||||
|
||||
gstreamer-launch filesrc location=music.mp3 ! mad ! osssink
|
||||
gst-launch filesrc location=music.mp3 ! mad ! osssink
|
||||
|
||||
This plays an mp3 music file music.mp3 using libmad, and:
|
||||
|
||||
gstreamer-launch filesrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
|
||||
gst-launch filesrc location=music.mp3 ! mp3parse ! mpg123 ! osssink
|
||||
|
||||
Plays and mp3 music file using mpg123
|
||||
|
||||
You can also stream files over http:
|
||||
|
||||
gstreamer-launch httpsrc location=http://domain.com/music.mp3 ! mad ! osssink
|
||||
gst-launch httpsrc location=http://domain.com/music.mp3 ! mad ! osssink
|
||||
|
||||
And using gnome-vfs you can do the same with:
|
||||
|
||||
gstreamer-launch gnomevfssrc location=music.mp3 ! mad ! osssink
|
||||
gstreamer-launch gnomevfssrc location=http://domain.com/music.mp3 ! mad ! osssink
|
||||
gst-launch gnomevfssrc location=music.mp3 ! mad ! osssink
|
||||
gst-launch gnomevfssrc location=http://domain.com/music.mp3 ! mad ! osssink
|
||||
|
||||
And too play the same song with gnome-vfs via smb:
|
||||
|
||||
gstreamer-launch gnomevfssrc location=smb://computer/music.mp3 ! mad ! osssink
|
||||
gst-launch gnomevfssrc location=smb://computer/music.mp3 ! mad ! osssink
|
||||
|
||||
Here we convert a Mp3 file into an Ogg Vorbis file:
|
||||
|
||||
gstreamer-launch filesrc location=music.mp3 ! mad ! vorbisenc ! disksink location=music.ogg
|
||||
gst-launch filesrc location=music.mp3 ! mad ! vorbisenc ! disksink location=music.ogg
|
||||
|
||||
And then we can play that file with:
|
||||
|
||||
gstreamer-launch filesrc location=music.ogg ! vorbisdec ! osssink
|
||||
gst-launch filesrc location=music.ogg ! vorbisdec ! osssink
|
||||
|
||||
Some other useful pipelines are..
|
||||
Plays wav files (currently there are no wav encoders):
|
||||
|
||||
gstreamer-launch filesrc location=music.wav ! parsewav ! osssink
|
||||
gst-launch filesrc location=music.wav ! parsewav ! osssink
|
||||
|
||||
Converts wav files into mp3 and ogg files:
|
||||
|
||||
gstreamer-launch filesrc location=music.wav ! parsewav ! vorbisenc ! disksink location=music.ogg
|
||||
gstreamer-launch filesrc location=music.wav ! parsewav ! mpegaudio ! disksink location=music.mp3
|
||||
gst-launch filesrc location=music.wav ! parsewav ! vorbisenc ! disksink location=music.ogg
|
||||
gst-launch filesrc location=music.wav ! parsewav ! mpegaudio ! disksink location=music.mp3
|
||||
|
||||
You can also use lame for mp3 encoding if you have it installed, it does a
|
||||
much better job than mpegaudio.
|
||||
|
||||
Rips all songs from cd and saves them into a mp3 file:
|
||||
|
||||
gstreamer-launch cdparanoia ! mpegaudio ! disksink location=cd.mp3
|
||||
gst-launch cdparanoia ! mpegaudio ! disksink location=cd.mp3
|

Record sound from your sound input and encode it into an ogg file:

gstreamer-launch osssrc ! vorbisenc ! disksink location=input.ogg

gst-launch osssrc ! vorbisenc ! disksink location=input.ogg

for mpeg1 with both audio and video (for glib2):
|

for mpeg1 with both audio and video (for gtk1.2, the shim doesn't handle the 'name' property yet):

For an avi file (DivX, mjpeg,...)

gstreamer-complete

gst-complete
|
||||
==================
|
||||
|
||||
This is a simple utility which provides custom bash completion when
|
||||
typing gstreamer-launch commands.
|
||||
typing gst-launch commands.
|
||||
|
||||
Simply run "gstreamer-compprep" as root to build the registry of completions,
|
||||
Simply run "gst-compprep" as root to build the registry of completions,
|
||||
and then put, in your .bashrc,
|
||||
"complete -C gstreamer-complete gstreamer-launch"
|
||||
(ensuring that gstreamer-complete is on your path).
|
||||
"complete -C gst-complete gst-launch"
|
||||
(ensuring that gst-complete is on your path).
|
||||
|
||||
You can then enjoy context sensitive tab-completion of gstreamer-launch

gstreamer-register
|
||||
gst-register
|
||||
==================
|
||||
|
||||
This tool will perform an introspection on all available plugins and will
|
||||
create a registry file in /etc/gstreamer/reg.xml. Startup time will be
|
||||
much faster since the gstreamer core doesn't have to bring all the plugins
|
||||
files into memory at startup. As with gstreamer-compprep you need to run this
|
||||
files into memory at startup. As with gst-compprep you need to run this
|
||||
as root for it too work correctly.
|
||||
|
||||
|
||||
gstreamer-inspect
|
||||
gst-inspect
|
||||
=================
|
||||
|
||||
Allows you to check the properties of plugins and elements.
|
||||
|
||||
./gstreamer-inspect
|
||||
./gst-inspect
|
||||
|
||||
will show all the plugins available and the elements they contain.
|
||||
|
||||
./gstreamer-inspect <pluginname/elementname>
|
||||
./gst-inspect <pluginname/elementname>
|
||||
|
||||
shows more info about the plugin/element.
