This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.
Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).
Should not lose any features/video formats.
* 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
These are the values officially registered in the base specification
(H.222.0/13818-1). Later on we can add other enums for other variants
Note that the enum is not used in the structure fields (such as a pmt
stream stream_type field) since it can contain values from other
variants.
* 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 :)
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
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).

It's not developed any more and replaced by the
libschroedinger-based elements in gst-plugins-good.
(The libschroedinger 1.0.9 release notes state "This
is an exciting release: most of the encoding tools in
dirac-research have been ported over to Schrödinger, so
now schro has the same or better compression efficiency
as dirac-research.")
TRM IDs are MusicBrainz' old audio fingerprinting system from
Relatable, they were phased out in favour of MusicIPs PUIDs.

This can be used by parsers to provide pre-parsed information to
downstream elements that would require it (so they can avoid having
to parse the bitstream again).
