1ffef8bf60 qtdemux: Increment current stts index whenever we finished one stts entry
Otherwise we could read more chunks than there are available, doing an
out of bounds read and potentially crash.

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).

59fd44a56f qtdemux: extract cover art images into GST_TAG_IMAGE not PREVIEW_IMAGE
These are usually much bigger than icon size and required by
iTunes to be certain fairly large sizes. In qtmux it is also
the IMAGE tags which we write out as 'covr' atoms.

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.

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.

45db90fdb0 qtdemux: When receiving a DISCONT buffer that does not point to a sample, remember the offset
And don't just reset everything. This makes sure that we can continue to
handle data in the following scenario:

moov: discont
moof: discont
mdat: continuous

Previously this would fail because the offset would be the accumulated offset
from moov and moof at the mdat position, while the buffer offset might be
something completely different.

e3923df800 qtdemux: Handle upstream GAP in push-mode/time segment
This is to handle cases where upstream handles the fragmented streaming in TIME
segments and sends us data with gaps within fragments. This would happen when dealing
with trick-modes.

When upstream (push-based, TIME SEGMENT) wishes to send discontinuous samples,
it must obey the following rules:
* The buffer containing the [moof] must have a valid GST_BUFFER_OFFSET
* The buffers containing the first sample after a gap:
 * MUST start at the beginning of a sample,
 * MUST have the DISCONT flag set,
 * MUST have a valid GST_BUFFER_OFFSET relative to the beginning of the fragment.
