e16be12e37 qtdemux: More 'meta' atom parsing fixes
Turns out everybody is doing it their own way, so peek into the
meta atom itself to figure out which spec it is following

4fd8635983 qtdemux: Minor cleanup
Just move variables to the blocks where they are used.

That function is massive, could do with some splitting up for
readability :(

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
at the major file type.

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If codec_data is changed, the stream is no longer valid.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.

8aa5c59b5f isomp4: Add official fourcc for VP8 codec
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.
