Add standalone test application that demonstrates how to use the new
VP8 bitstream parsing library, while also allowing simple debugging/
tracing of IVF files.

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.
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.
Tests for PAT, PMT, and NIT
Creates a new table, and populates it with descriptors.
Parses the newly created tables, and checks the data.
Creates a GstMpegTsSection from the tables, and packetize the sections.
The packetized section data is byte-wise compared to a static byte array

The thread that calls the success/failure callback can be the
same that is adding/removing the element as the IDLE probe can
happen instantly if the pad is not 'busy'.
This required moving some checks for the callback counter around
as well as removing some pad pushes from the main test thread as
they were made useless after the IDLE pad probe was fixed in core
by commit 0324358ebc
* stream-start-id is mandatory at the beginning, so add that to the
gdp headers
* caps must be sent before new segment, invert the order from legacy
0.10 code
And fix the tests as a ref is now kept for those buffers that compose
the header
Most of the tests weren't updated after the sticky events order
and stream start. Fix that and refactor those tests check that
are the same to some common functions.
Those functions still don't actually test the content but at
least now they are in a single place and can be improved
without replication
Commit 6af387cd5a made h264parse
strip a leading 0x00 byte from some output scenarios. This broke
tests as bs_to_nal test expects one more byte on the output.
Fix this by comparing the output with the expected stripped version,
too.
When outputting in AVC3 stream format, the codec_data should not
contain any SPS or PPS, because they are embedded inside the stream.
In case of avc->bytestream h264parse will push the SPS and PPS from
codec_data downstream at the start of the stream, at intervals
controlled by "config-interval" and when there is a codec_data change.
In the case of avc3->bytstream h264parse detects that there is
already SPS/PPS in the stream and sets h264parse->push_codec to FALSE.
Therefore avc3->bytstream was already supported, except for the stream
type.
In the case of bystream->avc h264parse will generate codec_data caps
from the parsed SPS/PPS in the stream. However it does not remove these
SPS/PPS from the stream. bytestream->avc3 is the same as bytestream->avc
except that the codec_data must not have any SPS/PPS in it.
|--------------+-------------+-------------------|
|stream-format | SPS in-band | SPS in codec_data |
|--------------+-------------+-------------------|
| avc | maybe | always |
|--------------+-------------+-------------------|
| avc3 | always | never |
|--------------+-------------+-------------------|
Amendment 2 of ISO/IEC 14496-15 (AVC file format) is defining a new
structure for fragmented MP4 called "avc3". The principal difference
between AVC1 and AVC3 is the location of the codec initialisation
data (e.g. SPS, PPS). In AVC1 this data is placed in the initial MOOV box
(moov.trak.mdia.minf.stbl.stsd.avc1) but in AVC3 this data goes in the
first sample of every fragment.

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.
Do state changes from sink to src. Fixes race condition in
pull mode test where the source will start up and push buffers
to queue/identity or aiffparse before the main thread has
managed to set them to playing yet.
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
