1. glcontextid function is replaced by gstreamer gst_gl_context_new_wrapped .
2. call gst_init before gst_gl_display_new , seems gst_gl_display_new depends
on gst_allocator_register , which only worked after gst_init called
3. flush gstreamer OpenGL context before using shared texture, fix
flicker problem.

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)
The reshape property was never used.
Replace the draw property with a signal.

ATSC has its own version of the EIT table (DVB also has one).
This patch adds parsing for the ATSC EIT table and also fixed
the section identification to mark it as the ATSC one.
The implementation aws refactored to reuse some common internal
structures from ETT.
Also adds its dumping function to ts-parser example
https://bugzilla.gnome.org/show_bug.cgi?id=730435
Adds the system time table structure and functions for convenient parsing of
it and for getting the UTC datetime that it represents. Also adds its
information dumping to the ts-parser example
https://bugzilla.gnome.org/show_bug.cgi?id=730435
Add a parsing function for MGT and also detect the EIT tables
for ATSC, the EIT pids are reported inside the MGT and we are still
only relying only on the table id for detecting it. In the future we
would want to also check the pid and compare with whatever the MGT
previously reported to confirm that it is indeed the EIT.

Before:
GST_GL_PLATFORM=cocoa GST_GL_WINDOW=cocoa
gst-launch-1.0 videotestsrc ! glimagesink
After:
GST_GL_PLATFORM=cgl GST_GL_WINDOW=cocoa
gst-launch-1.0 videotestsrc ! glimagesink
but still pass --enable-cocoa to configure script
because currently it can only be used with cocoa API.
We could later have cgl/gstglcontext_cgl.h that manages
a CGLContextObj directly and cocoa/gstglcontext_cocoa.h
would just wrap it.
So that it could be used with other Apple's window APIs.

Use COGL_VERSION_ENCODE to check for the minimum required and maximum allowed
cogl version. In certain situations just using the COGL_VERSION_* macro name can
give you the following error:
error "COGL_VERSION_MAX_ALLOWED must be >= COGL_VERSION_MIN_REQUIRED"
We create our textures (in Desktop GL) with GL_TEXTURE_RECTANGLE,
vaapi attempts to bind our texture to GL_TEXTURE_2D which throws a
GL_INVALID_OPERATION error and as thus, no video.
Also, by moving exclusively to GL_TEXTURE_2D and the npot extension
we also remove a difference between the Desktop GL and GLES2 code.

- cmake could not find glib
- put gtk variables at the beginning to avoid GL conflicts
- update examples to clutter-1.8
- use const instead of deprecated G_CONST_RETURN
- set max pending events to 0 to make cube example works again
On linux, the GSource func attached to the clutter_threads_add_idle
was not getting the cpu ressource periodically.
Because the use of clutter_threads_enter/leave inside the fakesink
callback seems to be too strong.
So remove the use if clutter_threads_enter/leave in the fakesink callback.
Then replace GQueue by GAsyncQueue to keep thread safe access to the
communication queues between clutter and gst-gl.
Call clutter_threads_add_idle with high priority.
It requires at least clutter 0.8.6 since lower clutter versions are
not compatible with GL_TEXTURE_RECTANGLE_ARB.
Remove use of ClutterEffectTemplace since it does not exist in
clutter 0.9.
The external opengl context must be specify when creating
our OpenGL context (glx) or just after (wgl).
When calling glXCreateContext or wglShareLists, the
external opengl context must not be current.
Then our gl context can be current in the gl thread while
the external gl context is current in an other thread.

Partially revert previous commit. It's not an issue with glimagesink
Xoverlay interface. It's always the same intel bug with direct
rendering redirection (the one that affects each opengl application
with compositing managers). It works fine with DRI2 and UXA
acceleration. Still leaving effects disabled because I'm testing intel
hardware that doesn't support FBOs.
GLimagesink XOverlay interface doesn't seem to work with composite
redirection on intel (and I believe ati too). Windows aren't
redirected offscreen at all. This commit just shows that the example
correcty works with ximagesink. The most evident difference I see is
that glimagesink reparents the xoverlay window into its own while both
x and xvimagesink destroy their window and render directly to the
xoverlay one.
Revert the "move windows" thing from commit
175f7a707bc922f3facc63e7d9b6d01f9bb6b1b0
Windows are offscreen who cares about their position? If you see the
windows something is going wrong with composite redirection.
This reverts commit 96e4ab18c2cf9876f6c031b9aba6282d0bd45a93.
You should have asked first. And you would have been told "no",
because it causes people on development branches to do a huge
amount of extra work.
Add xray effect. Maps luma to a negative, slightly cyan tinted, curve,
applies some light gaussian blur and multiplies it with its sobel edges. Not
sure about the name, likely to change. Probably still needs some tuning.
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.
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.
Serves as an example of usage of the new mpegts library from an
application.
Will parse/dump all sections received on a bus.
Usage is ./tsparse <any gst-launch line using tsdemux or tsparse>
Examples:
./tsparse file:///some/mpegtsfile ! tsparse ! fakesink
./tsparse dvb://CHANNEL ! tsparse ! fakesink
./tsparse playbin uri=dvb://CHANNEL
./tsparse playbin uri=file:///some/mpegtsfile
