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.

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.

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).

d6ea4d83f2 mpegtsbase: Fix when applying new PMT with same program number
When the sub-class is delaying deactivation of the old program,

overwrite the old program in the hash table and then steal
the new program back out of it. Instead, add the new program to
the hash table after handling removal of the old one.

d87177b69b mpegtspacketizer: handle early PTS conversion when a group has been found
In some cases, the PTS might be smaller than the first observed PCR
value which causes element to apply wraparound leading to bogus
timestamp. To solve this, we only apply it if the PTS-PCR difference is
greater that 1 second to be sure that it's a real wraparound.

Moreover, using unsigned 32 bits values to handle wrapover could end up
with bogus value, so it use pts value to handle it.

Also, convert pcr time to gst time before comparing it to pts.
Since refpcr is expressed in PCR time base while pts is expressed in GStreamer
time.

ab31900b64 tsparse: Fix per-program-pad pushing
This fixes a couple of issues regarding the output of (request)
per-program pads output:

We would never push out PAT sections (ok, that was one reallly stupid
mistake. I guess nobody ever uses this feature ...).

In the case where the PMT section of a program was bigger than one
packet, we would only end up pushing the last packet of that PMT. Which
obviously results in the resulting stream never containing the proper
(complete) PMT.

The problem was that the program is only started (in the base class)
after the PMT section is completely parsed. When dealing with single-program
pads, tsparse only wants to push the PMT corresponding to the requested
program (and not the other ones). tsparse did that check by looking
at the streams of the program...
... but that program doesn't exist for the first packets of the initial
PMT.

The fix is to use the base class program information (if it parsed the
PAT it already has some information, like the PMT PID for a given program)
if the program hasn't started yet.

531117b7df tsdemux: Push GAP events *after* deactivating old programs
The order in which program switch must happen is:
1) drain all data on old pads (but don't push EOS)
2) add new pads (but don't push any data on them)
3) Push EOS and remove old pads
4) Start pushing data on new pads

There was one caveat in this implementation, which is that when
we activate a sparse pad (step 2) we would push a GAP event. The problem
is that, while being an event, it is actually *data*.

We therefore need to make sure pushing those GAP event is done at the step
we start pushing data.
