Edward Hervey 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.

Sebastian Dröge 2b50a338c3 qtdemux: In gap mode, consider the mdat offset when calculating the remaining mdat size
The mdat generally does not start at offset 0, we have to include the
size of the moof and whatever else was in front of the mdat.

Enrique Ocaña González 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.

Jan Schmidt d76bd1913f qtdemux: matroskademux: Ignore repeated seek events
Similar to what was done in adaptivedemux, ignore seek
events we've already handled - such as when they are received
on every srcpad of files with lots of streams.

Sebastian Dröge a56a01f15f dashdemux: Update mdatleft from overall mdatsize and offset when observing a gap
Otherwise mdatleft will have a value calculated from the initial
mdatsize minus the parts of the stream that we saw, which is not
including all the parts of the stream that might've been skipped.

fragment so keep around any unused crypto info entries

Jan Schmidt 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.

David Warman 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).

the IMAGE tags which we write out as 'covr' atoms.

Jan Schmidt 107902ec51 qtdemux: Always snap to the start of the keyframe
When performing a key-unit seek, always snap to the start ts
of the keyframe buffer we landed on so that the keyframe is
entirely within the resulting outgoing segment. That seems
the most sensible result, since the user requested snapping
to the keyframe position.

Jan Schmidt f415730fdf qtdemux: Omit cslg_shift when snapping seeks
Segments times and seek requests are stored and handled
in raw 'PTS' time, without the cslg_shift - which only applies
to outgoing samples. Omit the cslg_shift portion when
extracting PTS to compare for internal seek snaps.

If the cslg_shift is included, then keyframe+snap-before seeks
generate a segment start/stop time that already includes the
cslg_shift, and it's then added a 2nd time, causing the
first buffer(s) to have timestamps that are out of segment.
