73f92371b8 basetsmux: expose pcr-interval property
Instead of using a static hardcoded PCR interval, allow the user
to configure it.

Also revert back the default to a 40 ms interval, that was changed
in recent patches for no good reason.

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.

9190541e3c tsmux: refactor logic for when to (re)transmit tables
In order to output them at regular intervals in the bitstream
when a bitrate is specified.

07235bbf46 mpegtsmux: Expose bitrate property
This allows outputting a Transport Stream with a constant bitrate,
by inserting null packets.

93e56ed473 mpegtsmux: Explicitly resend PAT/SI/PMT on force-keyunit events
And don't randomly change the PCR stream, which would cause a new PMT
version to be generated instead and could confuse players.

22dfd9aef3 mpegts: Unify API : GstMpegts / gst_mpegts_ / GST_*_MPEGTS_
It was previously a mix and match of both variants, introducing just too much
confusion.

The prefix are from now on:
* GstMpegts for structures and type names (and not GstMpegTs)
* gst_mpegts_ for functions (and not gst_mpeg_ts_)
* GST_MPEGTS_ for enums/flags (and not GST_MPEG_TS_)
* GST_TYPE_MPEGTS_ for types (and not GST_TYPE_MPEG_TS_)

The rationale for chosing that is:
* the namespace is shorter/direct (it's mpegts, not mpeg_ts nor mpeg-ts)
* the namespace is one word under Gst
* it's shorter (yah)

93a8137be6 mpegtsmux: Add support for muxing SI tables
The muxer is now able to include DVB sections in the transport stream.

The si-interval property will determine how often the SI tables are
muxed into the stream.

The section is handled by the mpeg-ts library. Below is a small example
that will include a Netork Information Table with a Network Name
descriptor in the stream.

GstMpegTsNIT *nit;
GstMpegTsDescriptor *descriptor;
GstMpegTsSection *section;
GstElement *mpegtsmux;

gst_mpegts_initialize ();

nit = gst_mpegts_section_nit_new ();
nit->actual_network = TRUE;

descriptor = gst_mpegts_descriptor_from_dvb_network_name ("Network name");
g_ptr_array_add (nit->descriptors, descriptor);

section = gst_mpegts_section_from_nit (nit);

// mpegtsmux should be retrieved from the pipeline
gst_mpegts_section_send_event (section, mpegtsmux);
gst_mpegts_section_unref (section);

b148c22cec mpegtsmux: Properly add subtitle descriptor for DVb subpicture subtitles
We were adding an empty descriptor for them and it was not possible to
actually use them on muxed streams.

e4a0c4d509 mpegtsmux: Set the program number from prog-map
The prog-map property of mpegtsmux only allows you to group pids together in a program.
The program number set in the PAT/PMT tables cannot be set explicitly.

This patch will set the program number according to the prog-map.
If a program id of 0 is given, the first vacant program number starting from 1 will be used.

130cf80752 mpegtsmux: fix PAT/PMT insertion frequency
The current code is comparing timestamps with different clock.
Let's use only the clock for PTS values.

Also rename frequency to interval, to avoid confusion. And remove
documentation about value 0, which won't work like documented.

6d554a5560 mpegtsmux: marking non-delta unit, including pre-sections
This patch address the issue observed with KF timestamps
and delta flag. When a section is appended before the keyframe,
it is not marked as non-delta. It's preferable to mark the
first buffer non-delta.

This patch also simplify the initial patch written by thomas,
since it does not clutter tsmux/ with a delta flag passed
around only for GStreamer convenience.
