3d8372cc50 devenv: Add some missing GStreamer specific env variables 
This should make "meson devenv" closer to what "gst-env.py" sets.

53ed876002 qtdemux: Do not send unnecessary GAP events 
Each stream may have its own segment timeline
(i.g., different segment.start or segment.base)
depending on edit-list and composition-to-decode atom.

Make sure whether time position of a stream has been actually
far behind than that of current target stream.

12e918428a qtdemux: Use a composition time offset of 0 for "no decode samples" for the time being 
This needs codec-specific handling, but using 0 instead of G_MININT32 at
least gives somewhat reasonable behaviour.

ad412d257b qtdemux: Always check ctts for unreasonably large offsets 
If this happens then ignore the whole ctts. Previously we only did this
if the PTS/DTS shift was determined from the ctts instead of the cslg.

93a10a4ba1 qtdemux: Dump composition time offsets in trun as signed integers 
Just like we do for ctts without regard of the version of the box.
Huge offsets are interpreted as negative offsets by qtdemux so this
works.

767e8bf668 qtdemux: Parse ctts version 
Negative composition time offsets are only allowed with version 1 of the
box, however we parse it as a signed value also for version 0 boxes as
unfortunately there are such files out there and it's unlikely to have
(valid) huge composition offsets.

284dd5443f qtdemux: Add support for version 1 cslg boxes 
They use 64 bit fields instead of 32 bit.

Also parse offset as a signed integer (in both versions) and clamp it to
a positive value as negative values don't really interest us here.

6cad2a7150 qtdemux: Fix can not demux Opus track made by qtmux 
Opus stream info is read from dOps box [1]. The offset of dOps box in Opus box is different in mp4a version 1 and 0 [2]. Calculate the offset of dOps box according to mp4a version.

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.

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

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.
