6b69ef24a1 qtdemux: Fix debug statement 
It was using the non-increasing offset variable, which made that statement
not so useful :)

d1ae39d6d6 qtdemux: Add macros for the various timescale conversions 
This helps make the code more readable and avoid future bad usage of
scaling function argument order.

9a903c994f qtdemux: Fix rounding errors in duration update 
Make sure we store updated segment stop/duration with the same
granularity as the duration timescale.

And add more debug

b40cfcfffb qtdemux: Update duration when we get more information 
When dealing with fragmented files, we will get more accurate duration
information via the mfra and moof atoms.

In order for playback to not stop at the initial duration (from the
moov atom), we need to check and update the various duration variables
when we find more information.

Fixes playback of fragmented files in pull mode

variables.

f4ca3c255a qtdemux: More fixes for reverse playback 
When seeking or finding the previous keyframe, do
comparisons against targets and segments using composition time
to correctly decide which sample times match.

find the last segment and start there.

148da6210a qtdemux: don't use GST_CLOCK_TIME_NONE in non GstClockTime variables

77f37a6b22 qtdemux: use track fragment decoding time (tfdt) in parse_trun() for interpolation 
As fallback if we don't have any existing samples
as reference point yet.

8a0f4e74e4 qtdemux: stop parsing headers for fragmented mp4s at the first moof 
Currently during header parsing, we scan through the entire file
and skip every moof+mdat chunk for fragmented mp4s, which makes
start-up incredibly slow. Instead, just stop at the first moof
chunk when have a moov, and start exposing the streams, so we
can go and start handling the moofs for real.

61bbd2d226 qtdemux: Handle empty segments when seeking in reverse play. 
Empty segments in an edit list have a media_start time of -1,
as they don't actually play any media. Allow for that when
aligning to the reference stream in reverse play.

488d0b93cd qtmux: don't limit max video resolution to 4096x4096 
MAX isn't entirely correct as upper limit either,
it should really be MAXUINT32, but it's unlikely
to be a problem in the near future.

9f85dfd733 qtmux: Do not infer DTS on buffers from sparse streams. 
DTS delta is used to calculate sample duration. If buffer has missing DTS, we take either segment start or previous buffer end time, whichever is later.
This must only be done for non sparse streams, sparse streams can have gaps between buffers (which is handled later by adding extra empty buffer with duration that fills the gap)

fa103ca5ad qtdemux: avoid crashing on dash streams 
DASH/fragmented moov might have no samples as those are carried
in moof fragments. Avoid crashing or failing the stream because
of that.

6e7930a10c qtmux: Make the default timescale 1/1800 second 
The old default timescale of 1 millisecond produces irrational
numbers for a lot of framerate/audio-packet-duration multiples.
1/1800 is a nicer number, as it tends to produce better fractions
and therefore slightly higher accuracy overall

ca068865c3 qtdemux: Improve framerate calculation/guessing 
Change the way the output framerate is calculated
to ignore the first sample (which is sometimes truncated
in my testing) and use the new gst_video_guess_framerate()
function to recognise common standard framerates better.

Remove the code that was sorting the first 20 sample
durations and then ignoring the result.

9dd48c503c qtdemux: forward DISCONT from upstream to the output streams 
This makes sense in DASH reverse playback, where the upstream dashdemux
will download DASH segments in reverse order, but push their buffers
forward to qtdemux and mark each segment start as DISCONT. This needs
to be forwarded downstream to the parser/decoder, otherwise it won't work.

overall file duration is also updated to reflect the
lengthening of the stream.

are longer than the file and get truncated.
