963dda3482 tsdemux: Make latency configurable
Allows for "low latency" mpeg-ts mode which is not standard, but somewhat common.
For this to work the sender has to put timestamps at a higher frequency than the spec requires.

eaf918df03 tsdemux: Limit the maximum PES payload size
PES packets with size 0 are unbounded, and
could therefore overflow the 32-bit size
accumulator.

Add a 32MB limit, which is larger than
any PES packet should ever get. If one does,
then output a 32MB chunk and continue.

a427b36f79 tsdemux: do not error if buffer size is invalid due to DISCONT
Don't signal a pipeline error when processing incomplete
j2pk PES packets that are too small. That can happen normally
during a DISCONT and shouldn't shut down the whole pipeline

bc4c221be3 tsdemux: always take the seek segment stop into account

b4a298c80e tsdemux: Use gst_segment_do_seek()
Remove some custom and incomplete seek calculation
logic in favour of gst_segment_do_seek(), and
short-circuit any actual seeking or recalculation
if the position didn't change and just send an updated
segment directly.

This removes the custom seeking logic in favour of
using standard core seek handling.

b7f95d64f8 tsdemux: Skew correction should use the upstream DTS
The MPEG-TS packetiser should use the upstream DTS for
skew correction when running in that mode, as the DTS
carries the upstream arrival time. The PTS (if it's
set at all) is less useful, and can be invalid.

89a85732d4 tsdemux: ignore sparse stream when checking for initial timestamp
Unless we only have sparse streams. In this case we will consider them.
It fixes a bug happening when first observed timestamp comes from a
sparse stream and other streams don't have a valid timestamp, yet. Thus
leading the timestamp from sparse stream to be the start of the
following segment. In this case, if the timestamp is really bigger than
non-sparse stream (audio/video), it will lead the pipeline to clip
samples from the non-parse stream.

52d0ef2665 tsdemux: Make jp2k handling more robust and efficient
* Avoid copying the pending data and instead create a buffer directly from
  that data with the appropriate offset.
* Locate the jp2k magic to determine the exact location of the (first) frame
  data instead of assuming that the header is of an expected size

c393f0d768 tsdemux: Handle quirk in jp2k es header handling
The jp2k specification (ITU-T T.800) specifies that the 'brat' box
has two fields and the second one (AUF2) can be set to 0 for progressive
streams.

The problem is that the mpeg-ts specification (ITU-T H.222.0 06/2012)
says that the AUF2 field is only present if the stream is interlaced

In order to cope with both situation, accept those next 32bit if the
stream is marked as progressive and those bits contain 0

60810cd057 tsparse: Convert PCR values immediately
Doing lazy conversion of PCR values doesn't work right
when a PCR discont is encountered. Instead, convert PCR
values to the continuous timestamp domain as soon as we
encounter them and store that instead.

0345fb8aef mpegtsdemux: fix operator precedence in SAFE_FOURCC_ARGS

argument will truncate to 8 bits and then shift right by 8 bits

ddacbb7793 mpegtsdemux: Ensure we always get an upstream stream-id
This was a regression.

We only have a upstream-id via STREAM_START if we were in push-mode.
In pull-mode we need to create one.

Note: It would be good to eventually have that method (copied from
gst_pad_get_stream_id_internal()) public in the future

fb36608ccd mpegts: Also clear packetizer on TIME DISCONT
When dealing with TIME-based input, the incoming stream could have
potentially changed completely.

In order to check whether it did or not, we need to re-check all sections
(PAT, PMT...). If it didn't, we will keep using the existing streams/pad,
and if it did we will act as if there was a program switch.

50473d77cc meson: Make mpegts lib build when using subprojects
The headers passed as parametter are relative to the build dir
basically "../subproject/gst-plugins-bad/gst-libs/gst/mpegts/XXX.h"
but that does not match what is needed at build time when building as
subproject, also we always add current dir as include_dir so we are
safe including directly.

And link mpegtsdemux against the 'math' library as it is needed.

42af2d66d8 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Matej Knopp <matej.knopp@gmail.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

51c5ff45de tsdemux: Fix draining on wrong programs
When draining a program, we might send a newsegment event on the pads
that are going to be removed (and then the pending data).

In order to do that, calculate_and_push_newsegment() needs to know
what list of streams it should take into account (instead of blindly
using the current one).

All callers to calculate_and_push_newsegment() and push_pending_data()
can now specify the program on which to act (or NULL for the default
one).
