7fbd1b472f qtdemux: Update segment.start after key-unit seek
When doing key uint seek, qtdemux calls gst_qtdemux_adjust_seek
to get proper offset. And then this offset is set to
segment.position and segment.time in gst_qtdemux_perform_seek but
segment.start is not updated.

After that, application sends segment query,
qtdemux sets start and stop to query using gst_segment_to_stream_time. Due
to the wrong value in segment.start, the stop position is smaller than
it should.

bf95f93c01 qtdemux: Don't accumulate segment bases manually
gst_segment_do_seek() does that for us already, and doing it twice
will break non-flushing seeks in interesting ways. Leftover from 1.0
porting.

Also copy over segment offset and applied_rate, just in case.

aeb4d32363 qtdemux: stbl_index is valid from 0 onwards
It indicates the last sample parsed, not the next one to parse.
As it starts in -1, any value from 0 onwards means that it has
some valid data.

ffa5fce094 qtdemux: Guard against 64-bit overflow
For large-file atoms, guard against overflow in the size field,
which could make us jump backward in the file and cause
infinite loops.

f75e443a7a qtdemux: fix key unit seek
Unlike many other seek flags, the KEY_UNIT seek
flag is not copied over into the GstSegment,
since it's only relevant for the seek itself,
so we need to pass it explicitly to the seek
handler here.

a12e41c106 qtdemux: prefer the tfdt timestamp over the buffer's that is less accurate
The tfdt should be more accurate as the buffer timestamp is provided
by the fragmented format manifest and it might just be an approximation.

afa5481c50 qtdemux: do not use sparse streams in push-based seeking
Using the sparse streams can make the push-based seeking return
too far in the stream. It also can lead to issues as the
sparse streams will be ignored when restarting playback and,
 if the sparse stream is the one that has the earliest sample,
it will confuse qtdemux's offsets as one stream will have
an earlier offset than the demuxer's one which might lead to
early EOS.

3a9b0188cd qtdemux: Initial 'sidx' atom parsing support
Parse the 'sidx' atom and update the total duration according to the
parser result. The isoff parser code is imported from
gst-plugins-bad's dashdemux and a gst_isoff_sidx_parser_add_data()
function was factored out of the gst_isoff_sidx_parser_add_buffer()
function.

Remove a fix for heavily edited files added for fixing

for a more general solution that bases on using previous

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.

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.

ca068865c3 qtdemux: Improve framerate calculation/guessing
Change the way the output framerate is calculated

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.
