d7038b9bb0 qtdemux: Handle variant of vorbis in mp4
Comes from gpac apparently. The codec_data uses the same packing
mechanism as matroska.

60bc77cc35 qtdemux: Check sample count is valid in PIFF parsing
The value stored in cenc_aux_sample_count wasn't in sync with the
parsing code that followed which checks whether all entries are
valid and present.

Only write the actual sample count when we know for sure.

850e678813 qtdemux: Fix seeking on streams with frame reordering
The samples table is sorted by DTS, not PTS. As such we can only get the
correct result when using a binary search on it, if we search for the
DTS.
Also if we only ever search for the frame, where the following frame is
the first one with a PTS after the search position, we will generally
stop searching too early if frames are reordered.

In forwards playback this is not really a problem (after the decoder
reordered the frames, clipping is happening), in reverse playback
it means that we can output one or more frames too few as we stop too
early and the decoder would never receive it.

357d77cf55 qtdemux: Cope with difference between QTFF and ISO BMFF specs
The 'meta' atom is defined differently in QTFF and BMFF, so try
to guess which spec the current stream applies to by looking

b415358c7e isomp4: Make 'hdlr' atom dump more flexible
The smallest possible is 24 (and not 25) bytes.

The last "name" field can according to QTFF specifications not be present
at all. The parser will handle this fine and so will the rest of
the qtdemux code.

ad8a6cb639 qtmux: send stream warning when refusing video caps
If codec_data is changed, the stream is no longer valid.
Rather than keeping running when refusing new caps,
this patch send a warning  to the bus.

Also fix up splitmuxsink to ignore this warning while changing caps.

c71cd08d0e qtmux: Allow configuring trak timescale per pad/trak
It generally makes not much sense to configure it for all pads/traks at
once as this value is usually different for each of them. As such, add a
new property on the pads in addition to the existing property on the
whole muxer.

6e21faffe7 qtdemux: Push a GAP event if there's a second *or more*

2e45926a96 qtdemux: Don't push GAP event if first buffer is within 1s
If we saw empty segments, we previously unconditionally pushed a
GAP event downstream regardless of the duration of that empty
segment.

In order to avoid issues with initial negotiation of downstream elements
(which would negotiate to something before receiving any data due to
that initial GAP event), check if there's at least a second of difference
(like we do for other GAP-related checks in qtdemux) before
deciding to push a GAP event downstream.

fourcc for VP8 codec is "vp08" defined by spec. To follow it,
add it to demux and change legacy VP8 fourcc "VP80" to "vp08" in mux.
Also, enable sync table in case of VP8 codec.

deb9c62cd9 qtmux: Un-merge the last two stsc entries after serializing
The last entry will most likely get new samples added to it in "robust"
muxing mode, changing the samples_per_chunk and thus making it wrong to
keep the last two entries merged. It will run into an assertion later
when adding a new sample to the chunk.

Thanks to gdiener@cardinalpeak.com for the analysis of the bug and
proposal for a solution.
