9996ae9ae0 tsmux: output smoothly increasing PTS when in CBR mode
Thanks to that, when its output is plugged into eg a udp sink, the
outgoing data can be output in a smoother way, reducing burstiness

f5495700fb basetsmux: don't reset pad on flush_stop
This was mistakenly added when porting to aggregator, this
restores the old behaviour, by only resetting them when the
muxer itself is reset

76c3d98962 basetsmux: preserve user-specified sections across resets
As sections can be provided by the user through send_event
when the element state is NULL, their lifetime is expected
to match that of the muxer, and they must be preserved when
the state changes

fdfd4600c1 atscmux: send empty RRT / MGT / STT tables
These are mandated by A/65, their absence gets flagged by
stream analyzers. Users can of course provide filled up
versions through the send_event API.

5d41740ff6 tsmux: maintain packet counters in a global array
We can have multiple TsMuxPacketInfo objects for the same PID
with user-provided sections, for example ATSC requires multiple
tables with the same PID.

91c76b0851 mpegtsmux: restore stream creation order
In 7c767f3fcd , stream creation was
refactored to occur before potential program creation. This created
issues with pipelines such as:

gst-launch-1.0 videotestsrc ! video/x-raw, format=I420, width=640, height=640, framerate=25/1 ! \
x264enc ! hlssink2 target-duration=1

eg.: gst_buffer_copy_into: assertion 'bufsize >= offset + size' failed

As this reordering was actually not needed for the purpose of allowing
to specify a PCR stream, this reverts the reordering part of the
initial commit.

14b9a34f54 mpegtsmux: add custom AC-3 descriptor
tsdemux expects a custom descriptor (GST_MTS_DESC_AC3_AUDIO_STREAM)
to detect a stream as AC3 and not EAC3.

Note that tsdemux expects this descriptor because mpegtsmux writes
a stream with a HDMV registration descriptor.

Fixes:

gst-launch-1.0 -v audiotestsrc ! avenc_ac3 ! ac3parse ! mpegtsmux ! \
tsdemux ! ac3parse ! avdec_ac3 ! audioconvert ! autoaudiosink

3fe65ad854 tsmux: Store PES payload size in a 32 bit integer
While the size in the packet is only 16 bits, we need to handle bigger
sizes without overflowing. For video streams this can happen, 0 is
written to the stream instead.

This fixes muxing of buffers >= 2**16.

1630d2a0d7 mpegtsmux: fix buffer size mismatch in M2TS mode
In M2TS mode, we need an extra 4 bytes in the buffer, so need
to ensure the buffer can contain these. The allocation site
does not know the mode, so this is done in all cases.

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.
