Because gst_ts_demux_reset is called after the properties have been

mpegtsdemux: Avoid parsing section without enough data

This is actually a workaround (we'll be skipping the upcoming section)

This will only happen for sections where the beginning is located within
the last 8 bytes of a packet (which is the minimum we need to properly
identify any section beginning).

Later we should figure out a way to store those bytes and mark that
some analysis needs to happen. The probability of this happening is
too low for me to care right now and do that fix. There is a good chance
that section will eventually be repeated and won't end up on such border.

Thiago Santos [Tue, 9 Jul 2013 02:24:28 +0000 (23:24 -0300)]
dashdemux: handle live playback resync

During a live stream it is possible for dashdemux to lag behind on a
slow connection or to rush ahead of the connection os too fast.

For the first case it is necessary to jump some segments ahead to be able to
continue playback as old segments are usually deleted from the server.

For the later, dashdemux should wait a little before attempting another
download do give time to the server to produce a new segment

When using a template based segment list, do not try to
contruct a finite segment list for the limits of the available periods.

We might not know when the period ends (for live streams) and we can
always create the segment on demand when requested by dashdemux,
avoiding use of some memory and cpu when re-creating this list.

return NULL on the fetch function and leave the downloader ready

mpegtsdemux: Fix multiple-SI detection/parsing

We had two issues with the previous code:
1) We were badly handling PUSI-flagged packets. We were discarding the
   initial data (if pointer != 0) whereas we should have been accumulating
   it with the previous data (if there was a continuity of course).
   => First series of information loss
2) We were not checking whether there were more sections after the end
   of one (i.e. when the following byte was not a stuff byte).

This fixes those two issues.

mpegtsdemux: Handle private section streams

Until now we simply ignored those streams (since we couldn't do anything
with it anyway). Now that we have the mpegts library and we offload the
section handling to the application side we can properly identify and
extract them.

By default it is disabled for tsparse and enabled for tsdemux, but there is
a property to change that.

This should open the way to properly handle all private section streams,
including:
* DSM-CC
* MHEG
* Carousel data
* Metadata streams (though I haven't seen any of those in the wild)
* ... And all other specs/protocols making use of those

Partially fixes #560631
