17630760f4 qtdemux: more work at reducing loop overhead
Try to avoid derefs when parsing the index. Save the state into the structures
when we exit the loop instead of for each iteration.

91a5e5138f qtdemux: cleanups and make duration more accurate
Make the QtDemuxSample struct smaller by keeping the duration and the pts_offset
as their 32 bit values.
Make some macros to calculate PTS, DTS and duration of a sample.
Deref the sample index less often by keeping a ref to the sample we're dealing
with.

22eb18f828 qtdemux: simplify logic to calculate duration
Since we no longer store the timestamp and duration in nanoseconds, we can now
simply store the duration as-is.

1c27ed4dae qtdemux: Store timestamps in mov format in the index
This allows faster building of the index upon seeks so that scaling of
timestamps only occurs when actually needed.

86021857c5 qtdemux: make seeking in push mode work
Move sample position checks into qtdemux_parse_samples where we can protect it
with a lock.
Refactor and make an qtdemux_ensure_index function.
Rename qtdemux_do_push_seek to qtdemux_seek_offset in order to avoid confusion
with gst_qtdemux_do_push_seek.

6c4c8f8670 qtdemux: fix up language code extraction some more
Quicktime uses ISO 639-2 for language codes, but GST_TAG_LANGUAGE
is supposed to hold a ISO 639-1 code, so convert as needed using
the new API from -base.

from the gama atom) if available.

c8c9b0f35d qtdemux: move stco, stts, stss and stps atom parsing over to GstByteReader
Make sure we don't read beyond the atom boundary. Note that the code
behaves slightly differently in the corner case where there is not
enough atom data for the specified number of samples (n_samples_time)
in the atom, but still enough data to fill the pre-allocated index of
n_samples entries: before we would just stop parsing the stts data
and continue, whereas now we will likely error out. This should not
be a problem in practice though. We could maintain the old behaviour
by doing reads with a size check inside the loop if needed.

405aae4568 qtdemux: guard against bogus atom sizes and short reads
Check the possibly 64-bit atom size more carefully before casting it

dereferencing not available data whilst thinking we actually asked
for and got 0x1000000000000 bytes. Similar fix for push mode operation
where neededbytes ends up being 0 bytes, which makes us assert. Fixes
crash with broken or fuzzed file (NB #122378).
