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.

b55dfb5313 Add feature options for almost all plugins
The only plugins remaining are those that haven't been ported to Meson
yet, and msdk. Also, the tests are still automagic.

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

encounter them and store that instead.

0345fb8aef mpegtsdemux: fix operator precedence in SAFE_FOURCC_ARGS
Type cast has higher precedence than bitwise shift, so the third
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).
