195470a785 mpegts: turns out glib aborts on allocation failure
So this is actually pointless. We'll just have to ignore
Coverity moaning on those.

Revert "mpegts: test for allocation failure"

This reverts commit 224cb81b8f.

224cb81b8f mpegts: test for allocation failure
While it's unlikely to get there, it silences the coverity warning
on the error code path that we test for NULL before freeing, when
all branches there are from locations where pmt cannot be NULL,
and removing the NULL check makes the code more vulnerable to a
hypothetical future branch from somewhere where it can be.

4190a1717a mpeg-ts: Rename private function
Calling it _desc_checks when it was in fact used for sections was a
tad confusing ...

972f7ea71f mpegts: Fix some packetizing bugs
- Length of NIT stream descriptors was not detected correct
- Reserved bits was not set according to EN 300 468, ISO/IEC 13818-1
- Also set output data size if the section was previously packetized

8f429c6c6e mpegts: Add functions to send sections as events
Added function that enables the user to send a GstMpegTsSection as
an event to a GstElement. (i.e. mpegtsmux)

930cde73a7 mpegts: Add functions to packetize section
Sections needs to be packetized for use in i.e. mpegtsmux.
These functions handles the generic common parts of a GstMpegTsSection

5d06aed3e2 mpegts: ABI/API break: Use GPtrArray instead of GArray
While it was a great idea, various g-i based bindings don't support
GArray with entries greater than sizeof(gpointer) :(

So let's just make everybody happy by just using GPtrArray.

And since we're breaking the API, also rename the various descriptor fields
to no longer have the descriptor_ prefix.

It does cost a bit more in terms of memory/cpu usage, but makes it usable
from bindings.

ae4d6bb334 mpegts: Unify section checks and add BAT parsing
* Avoid repeating code everywhere, and instead provide all parsing
  information in one go.
* Add BAT support
* Refine BAT/CAT identification (by adding PID checks)

f3d53fcd97 mpegts: Avoid false-positives in section type detection
Due to the variety of section types out there, we need to add
some checks when identifying section types.

We check here that the PID is also consistent with the table_id.

f24c0b62e3 mpegts: Improve documentation
* Add a base page for the library
* Add pages for the base MPEG-TS section and descriptors
* Add pages for the known variants
* Add documentation on more fields/sections/types
* Remove some fixmes that were ... fixed

982aee25c6 mpegts: Split files and implement free functions
* In order to avoid future clashing between table_id for the various
  mpeg-ts variants, use different enums.
* In order to keep everything clean(ish) and allow for cleaner growth,
  split into different files (will need the same for descriptors later)
* Also ... implement free functions for all table types :)

c1366efcd6 libs/mpegts: Rename GstMpegTS => GstMpegTs
Sorry for this :( But this makes it more in sync with expected type
naming in gobject (i.e. CamelCase and not CamelMAYBECase).

Also split descriptor type enums into the different variants:
* ISO H.222.0 / 13818-1 (i.e. standard mpeg-ts)
* DVB
* ATSC
* ISDB
* miscellaneous

This will avoid future clashes when specs use the same descriptor type

3665e8543a gst-libs: New Mpeg-TS support library
Exposes various MPEG-TS (ISO/IEC 13818-1) and DVB (EN 300 468) Section
Information as well as descriptors for usage by plugins and applications.

This replaces entirely the old GstStructure-based system for conveying
mpeg-ts information to applications and other plugins.

Parsing and validation is done on a "when-needed" basis. This ensures
the minimal overhead for elements and applications creating and using
sections and descriptors.

Since all information is made available, this also allows applications
to parse custom sections and descriptors.

Right now the library is targeted towards parsing, but the structures
could be used in the future to allow applications to create and inject
sections and descriptors (for usage by various mpeg-ts elements).
