cf6733a55e qtdemux: check for a different stsd entry before pushing a sample
Before pushing a sample, check if there was a change in the current
stsd entry. This patch also assumes that the first stsd entry is
used as default for the first sample. It might cause an uneeded
caps renegotiation when this isn't the case.

86b427dc70 qtdemux: parse all stsd entries
stsd can have multiple format entries, parse them all.

This is required to play DVB DASH profile that uses multiple entries
to identify the different available bitrates/options on dash streams

The stream format-specific data is not stored into QtDemuxStreamStsdEntry

54e252e095 qtdemux: rework stsd sample entries access
Instead of using the stsd as a base pointer, use the actual stsd
entry as the stsd can have multiple entries. This is rarely used
for file playback but is a possible profile with in DVB DASH specs.

This still doesn't support stsd with multiple entries but makes it
easier to do so.

6b889bea69 qtmux: Select the best pad based on the cached last_buf if any
last_buf is the one we're going to write next, not buf. As such we
should check timestamps against that one if there is one to select the
earliest pad.

Also remember the currently selected pad in the very beginning when
storing the first last_buf.

This both solves some edge cases where not the correct next pad was
selected corresponding to the target interleave.

1e4cdc6d6f qtdemux: Update variables before early exit
This is an update of d78d589627

We still exit as early as possible in case of non-ok/non-unlinked combined
flow, but we first make sure that we update the internal position variables.

This ensures that if upstreams "ignores" the flow return (and carries on pushing),
we don't end up processing data with completely bogus variables/positions.

28a57d0586 qtdemux: distinguish TFDT with value 0 from no TFDT at all
TFDTs with time 0 are being ignored since commit 1fc3d42f. They're
mistaken with the case of not having TFDT, but those two cases
must be distinguished in some way.

This patch passes an extra boolean flag when the TFDT is present.
This is now the condition being evaluated, instead of checking for
0 time.

9c121b09a5 qtmux: Reset current chunk after writing out timecode
If we have multiple tracks with timecodes, or it's not the first track
that has timecodes, or not the first buffer, we already started a chunk
for media data. We now need to "close" that chunk because we wrote data
for the timecode track and a new chunk has to be started for the
original track the next time it has data.

b434ba86f1 atomsrecovery: also handle extra atoms after 'mdia' in a 'trak'

488e8edba4 Revert "qtdemux: Always snap to the start of the keyframe"
This reverts commit 107902ec51.

This commit intended to ensure that keyframe seeks land at the
start timestamp of a keyframe, rather than in the middle of one,
but they cause trouble on files with sparse streams, or with
JPEG 'cover art' tracks that have only one or a few JPEG samples
with very long durations.

That's still desirable for doing seamless cutting of videos,
but needs a rethink for implementation.

af47e93b97 qtmux: Timecode track fixes for STSD entry
The n_frames field (frames per second) should follow the nominal frame
rate for drop-frame timecodes.

Also, the trak's timescale (and duration, accordingly) should follow the
STSD entry's timescale and frame duration (fps_n and fps_d accordingly),
not the other way around.

642331fd7f qtdemux: avoid XMP tag parsing fatal error.
qtdemux_handle_xmp_taglist() requires a writable taglist,
but qtdemux->tag_list can become non-writable, specifically
after sending global tags (qtdemux.c:958), which adds a
second reference.  Ensure the list is made writable before
calling (make_writable will copy the list if necessary).
