379059b1c7 qtmux: Make sure timecode uses the same timescale as video
Don't blindly derive it from the frame rate, but try to get the per-pad
configured timescale first (if it exists)

55f949676e qtmux: Add new prefill recording mode
This sets up a moov with the correct sample positions beforehand and
only works with constant framerate, I-frame only streams.

Currently only support for ProRes and raw audio is implemented but
adding new codecs is just a matter of defining appropriate maximum frame
sizes.

e51c08b0a2 qtmux: Fix timescale of timecode tracks
They should have ideally the same timescale of the video track, which we
can't guarantee here as in theory timecode configuration and video
framerate could be different. However we should set a correct timescale
based on the framerate given in the timecode configuration, and not just
use the framerate numerator.

1426a55a83 qtmux: Clear edit lists every time we recalculate them
We recalculate them, so any old information has to be forgotten.
Otherwise we write invalid edit lists when writing headers multiple
times.

e12c94065d qtmux: Write tapt atom for MOV files if PAR not 1/1
Needed for QuickTime 7 to properly play files.

Also write the clap atom for MOV files always, not only when ProRes is
used as a video codec. It's mandatory for MOV.

12ad37fdb3 qtmux: Write tfdt atom into fragmented files.
The DASH spec requires that tfdt atoms be present, so
write one out. ISO/IEC 23009-1:2014 6.3.4.2

a2c6921482 qtmux: Write 'clap' atom for ProRes
It's required for ProRes to work with other software.

It is also in the MP4 standard, but inventing values here seems a bit
tricky for the general case and it does not really give any extra
information.

JPEG2000, not only for ProRes.

ab18f5035c qtmux: add AC-3 muxing support
Adds AC-3 muxing support. It is defined for mp4 and 3gp formats.

One extra feature that was added was the ability to add extension
atoms after set_caps as the AC-3 extension atom needs some data
that has to be extracted from the stream itself and is not
present on caps.

1d058c7d8a isomp4: Implement robust muxing using ping-pong strategy
Implement a robust recording mode, where the output
file is always in a playable state, seeking and rewriting
the moov header at a configurable interval. Rewriting
moov is done using reserved space at the start of
the file, and a ping-pong strategy where the moov
is replaced atomically so it's never invalid.

Track when tags have actually changed, and don't write them into
the moov unless they've changed. Clear any existing tags when
re-writing them, so we can do progressive moov updating in robust
recording mode.

Write placeholder mdat as a free atom plus a 32-bit mdat
with '0' size, which means "rest of the file" in the spec.

Re-write it later to a full 64-bit extended size atom if needed.

updating existing table entries if they already exist instead of just
adding new ones.

6321cdedb3 qtmux: refactor tags functions to accomodata UDTA at trak level
Refactor the functions that were bound to the 'moov' atom to
directly pass the desired 'udta' that should receive the tags.
This allows the tags to be written to 'udta' at the 'moov' or
the 'trak' level, creating tags that are for the container or
for a stream only.

a null terminated one. Store the current atoms flavor into the HDLR
