f6ed40c93a qtdemux: Fix text and closed-caption handling. 
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1182
broke text and and closed caption extraction when introducing WebVTT
support, by making the output buffers not have timestamps any more.

Fix that by making the process functions copy buffer metadata
when generating new output buffers.

0ba65a00c9 matroska: Treat non-image structure as attachment 
Otherwise each structure is named as GstTagImageInfo even if
it does not contain any images which is misleading.

8c35850f23 rtpbin: fix leak of pad when a fec encoder and aux sender a created 
The ghost sink pad retrieved by rtpbin from the aux sender was not freed
when there was a previous element (fec encoder) in the chain.

6cada5b064 qtdemux: Add support for wvtt (WebVTT) subtitles. 
WebVTT in ISO MP4 is specified in ISO 14496-30,
and needed for DASH support. It's stored in an
mp4 specific format. To handle it compatibly,
the wvtt boxes are converted back into WebVTT text
and pushed as application/x-subtitle-vtt

41d6f47f2b isomp4: Split buffer process functions. 
Split the different handling for closed captions, VobSub subpicture
and timed text samples into separate simplified process functions.

c47c6b4c2b isomp4: Use a function pointer for buffer splitting. 
Swap the `need_process` boolean check on qtdemux streams
for a direct function pointer to the splitting function,
so we can stop adding extra cases to the single growing
`gst_qtdemux_process_buffer()` function.

4316be6571 splitmuxsink: Keep track of the pending input GOPs in a queue 
This cleans up input GOP handling and makes it possible to handle more
than 2 pending GOPs, which could happen before if keyframes are arriving
with too short of a distance between them.

ae8ceb801c splitmuxsink: Handle frame reordering due to B frames better 
Instead of assuming that the PTS of a keyframe is the lowest PTS of a
GOP, wait until the DTS has passed this PTS and take the minimum PTS up
to that point. That way the minimum PTS of a GOP can be determined, at
least for closed GOP streams. Open GOP streams still can't be handled
properly.

By knowing the minimum PTS of each GOP, keyframes can be requested at
the correct time relative to the GOP (and thus fragment) start and
fragment overflow calculations can calculate the correct durations of
the GOPs.

ed6823ad67 splitmuxsink: Use GST_CLOCK_STIME_NONE instead of 0 to initialize max out running time 
Otherwise streams with only DTS would misbehave while it is negative.

For outputting everything immediately at EOS, use G_MAXINT64 instead
which is bigger-or-equal to any other running time.

5ec82c1c4e rtphdrext: Pass just the attributes to the subclass 
Since the base class now does the parsing, there is no need
to reproduce that code in all the subclasses, just pass the attributes
which are the only relevant bit anyway.

Also, only store the direction if the subclass accepted the caps
