Sebastian Dröge 211cd095d6 Add new mux subdirectory for container formats 
Contains the (incomplete) flavors FLV demuxer and the fragmented MP4
muxer for now.

François Laignel 6319d104a8 Take advantage of Into<Option<_>> args 
Commit 24b7cfc8 applied changes related to nullability as declared
by gir. One consequence was that some functions signature ended up
requiring users to pass `Some(val)` when they could use `val`
before.

This commit applies changes on `gstreamer-rs` which, will honoring
the nullability stil allow users to pass `val` for the few affected
functions.

This commit also fixes the signature for `Element::request_new_pad`
which was updated upstream.

Sebastian Dröge 9b85dcc03b fmp4mux: Drop GAP buffers before doing ONVIF UTC time re-timestamping 
GAP buffers won't have the reference timestamp meta.

Sebastian Dröge 36ce8bd4f7 fmp4mux: Implement a better strategy for splitting fragments and deciding which buffers go into which fragment 
It is now guaranteed that each fragment is at most fragment-duration
long unless the one and only GOP of the fragment is longer than that.
The first (non-EOS) stream determines the duration of each fragment and
all other streams are drained to at most the fragment end timestamp
determined this way.

In addition the next fragment's target time is now at the end of the
previous fragment plus fragment-duration instead of using
  first-fragment + N*fragment-duration
regardless of where fragments were split before.

That is, fmp4mux now uses the same strategy as used by splitmuxsink and
as is required e.g. by HLS with regards to the target duration.

Sebastian Dröge 7e13ea4ba9 fmp4mux: Drop gap buffers before further processing 
They would potentially change timestamps and will break in ONVIF mode.

Mathieu Duponchelle 052092cd2e onvifmetadata: removing encoding field 
The encoding of ONVIF metadata is always UTF-8. ONVIF metadata may
or may not be encoded with gzip, but we don't see a use case for
transporting compressed ONVIF metadata between elements for now.

Sebastian Dröge 84f6484140 fmp4mux: Consider invalid running times as zero and before anything else 
The code tried to do this before but didn't consider the case where the
first pad has a valid running time, in which case the buffer with the
invalid running time would never be dequeued and the muxer would never
output anything.

Sebastian Dröge 2c99f66ea5 fmp4mux: Dequeue the earliest buffer from any pad first instead of dequeueing up to a whole fragment from the same pad 
This keeps the fill levels of each sinkpad in sync.

François Laignel 6a2df92453 Revert "fmp4mux: Dequeue as many buffers as are available in each aggregate call" 
This reverts commit 402500f79c.

This commit introduces race conditions. It was intended as solving
an issue with some pipelines which had their queues filling up,
causing the streams to stall. It is reverted as this solution is
considered a workaround for another issue.

Sebastian Dröge d6fa921822 fmp4mux: Use saturing_sub() in more places 
On unclean input, PTS/DTS might go backwards a bit and in those cases
calculate a duration of 0 instead of panicking.

Sebastian Dröge 6bca5a9962 fmp4mux: Implement interleaving based on start timestamps instead of accumulated durations 
Durations might accumulate rounding errors and streams might not
actually start at the same time. For that reason also start with the
stream that has the lowest timestamp.
