f1c61e1d84 qtdemux: Use the correct duration when comparing segments 
Do not confuse QtDemuxSegments with GstSegments when
comparing the total file duration with the segment duration

2723de585e qtdemux: add durations modulo 1<<32 
For calculating the durations of each sample, we are supposed to add each
duration modulo 1<<32 so make the elapsed time counter a uint32.

d14685eb08 qtdemux: fix ALAC codec-data handling 
ALAC codec-data apparently comes in (at least) two flavours (mov, mp4),
so use atom based parsing to retrieve required data, rather than
aiming for a specific offset.

See also #580731.

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.

Reverting this since it causes regressions with a lot of sample files
I have, all of which worked fine with the last -good release (#586891).

8fa148d2f1 qtdemux: more size checks, and use g_try_new0() instead of g_new0() 
Whenever we alloc something based on a user-supplied size, we should
really use g_try_new(), otherwise we can easily be made to abort by
passing a ridiculously large number to us for allocing. Fixes
problems with some fuzzed files.

405aae4568 qtdemux: guard against bogus atom sizes and short reads 
Check the possibly 64-bit atom size more carefully before casting it
to an int and passing it to gst_pad_pull_range(), otherwise we might
end up pulling 0 bytes, getting an empty buffer as requested and
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).

790b050fc5 qtdemux: fill timestamp table completely 
When there are less timestamps that there are samples, fill up the sample table
with the last know timestamp. This situation can happen when the last sample
does not decode and doesn't need a timestamp. We however calculate the total
track length using the last sample timestamp so we need to have something
sensible in there.

the endianness right.

922c9f529a qtdemux: override caps based on data from ESDS atoms in mpeg4. 
If the codec is actually something else (e.g. mjpeg) change the caps to
match when parsing the ESDS atom.
Also, for AAC, override rate and channels with correct values read from
ESDS, since the rate/channels values elsewhere are often wrong.

which stalls the pipeline if seeking into that region.

sparse (subtitle) streams (at some later time ?)
