6bf6429bc1 mpegtsmux: Remove redundant min_dts
After few iteration, this variable became the same as dts. It's not
the min as the name says, but the dts of the current buffer. Simply
remove and place with dts. Also move the debug trace to actually
print the signed version of the running-time dts.

e000a6f0a4 tsmux: Add negative DTS support
Use the saved DTS, make it signed and pass that to the stream muxer. This
preserves the running time sign. All usage of -1 as invalid TS are now
replaced with G_MININT64. Negative values will be seen as wrap-around
point, but the delta between PTS and DTS will remain correct. Demuxers
don't care about absolute values, they only cares about deltas.

43621624c8 mpegtsmux: Carry over GST_BUFFER_FLAG_HEADER
In the same way we do it for the DELTA_UNIT flag

This allows downstream elements to know whether a given mpeg-ts
packet contains a corresponding HEADER elementary unit

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);

14a56b6964 mpegtsmux: Don't disrupt buffer state in the clip function
Collectpads assumes that it can pass any buffer to the clip function
for adjustment, some of which are artificially injected - so don't
adjust global timestamp tracking there. Instead, only adjust the
buffer timestamps and use them directly in the collection function.

9a26173a57 Rewrite M2TS packet output
Make sure we only write the bottom 30 bits of the PCR to the m2ts header.
Don't use floating point computation for it, and remove weird bit fiddling
that messes up the PCR in a way I can't find any
justification/documentation for.

Don't accidentally lose PCR packets from the output.

Fix the description for the m2ts-mode property so it's clear it's a flag,
and which setting does what.

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.

6f1ee59df6 mpegtsmux: generate SPS/PPS header once and fix overflow
Some H264 packets can be as small as 5 bytes for repeated frames.
In such a situation the output buffer size was not big enough (5*2) to fit the
SPS/PPS header and the start codes. This corrupts the ES stream.
We now generate the SPS/PPS only once which is much more optimal and we now
know the size of the header to calculate the output buffer size more safely.
