3eb033bba2 mpegts: GST_EXPORT -> GST_MPEGTS_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

9cc00bf2c9 mpegtsmux: write language descriptor when language is available
Adds a new function to mpegts lib to create a iso639 language
descriptor from a language and use it in mpegtsmux to add
a language descriptor to audio streams that have a language set.

90b27a3c8b mpegts: Add padding to public structures
Allows use to add API in the future without breaking ABI. We broke the API/ABI
once between 1.2 and 1.4, let's try to avoid this in the future even if this
is an unstable library.

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)

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.

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

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).
