Increased performance doing pull_range in blocks of 32Kb instead of 4Kb.
Caching the value of gst_adapter_available instead of calling it 3 times.
Added some comments with the header descriptions.
Peek enough data to avoid a corner case where could be readed data outside
the buffer.
Speed up some more inlining some functions and keeping another stream pointer
list to be used as iterator.
Sprinkle branch prediction macros accross the code.
Handling the seeking with flush in pull mode in the proper way.
If there is an ISO 639 language descriptor for a stream, send a language
code tag so that players can show a meaningful language for the audio and
subtitle streams.
Don't treat some streams (Private Stream 2) as LPCM when they're not. Fixes
playback of files that have private streams in them now that the PES filter
emits such packets.
If the estimated bitrate is lower than 188 bytes, there's most likely
something completely wrong with the two samples. If that happens,
force recalculation.
Use guint64 for observation PCR, I saw cases where it would overflow.
This allows debugging with mpegtsdemux:4 while being able to track what's
going on (and avoid taking up as much cpu for debugging as for the actual
demuxing process).
Sync from gst-fluendo-mpegdemux and have seeking/duration query
improvements in. No support however for wrapped around pcrs etc. but a
start nonetheless.
Also fix indentation issues.
This should remove the bogus error messages while still keeping the original
intent of this, which is to inform the pipeline/application/user that we
could not find any valid streams.
There are many reasons why pushing an event can fail, and not all of them are
because there's no link downstream (it could be because it was blocked, or
flushing).
itvhd masks its h264 video stream as a private stream making it harder for
other set top boxes to decode. this checks for specific program number, video
pid and stream type combination before declaring it as h264.
don't ignore the return value of pull_range because we only get a valid non-NULL
buffer when the return value is GST_FLOW_OK. Avoids a crash when the pipeline is
shutting down.
Ensure that the clossing segment is generated correctly and being
properly pushed.
Added some GST_DEBUG to check it.
Ensure that last_stop is updated in stream time.
Calculate duration as delta of PTS as it seems more correct than delta
of SCR in some clips that I tested.
Removed a line wrongly copy pasted in my previous commit.
Avoid an unsigned integer overflow.
Seek last_stop in stream time.
Clamp last_stop in stream time between first and last SCR.
Fixed a typo in the GST_DEBUG line and added some more info.

Don't forward duration requests in BYTES, since the returned
value doesn't mean anything. Fixes#566959

Fix up terrestrial delivery system descriptor defs.
They should be shifted otherwise wrong values are seen.

* gst/mpegdemux/gstmpegdemux.c: (gst_flups_demux_src_query):
Converting from time to bytes operates on the stream_time, not the SCR
timeline.
The position reporting should happen in stream_time, not the segment
timestamp range. See #557161.

If we're going to send a NEWSEGMENT event but the segment start
and the current buffer timestamp differ by more than a second we
will start the NEWSEGMENT at the buffer timestamp.
This fixes playback of the tv2-1_25.mpg file, which has 0 as first SCR
