From man open(2):
The O_CLOEXEC, O_DIRECTORY, and O_NOFOLLOW flags are not specified
in POSIX.1-2001, but are specified in POSIX.1-2008. Since glibc
2.12, one can obtain their definitions by defining either
_POSIX_C_SOURCE with a value greater than or equal to 200809L or
_XOPEN_SOURCE with a value greater than or equal to 700. In glibc
2.11 and earlier, one obtains the definitions by defining
_GNU_SOURCE.
And indeed, with the uClibc C library, O_CLOEXEC is not exposed if
_GNU_SOURCE is not defined. Therefore, this commit fixes the build of
gstreamer-vaapi with the uClibc C library.

gst_video_info_set_format() and gst_video_info_from_caps() call, internally,
gst_video_info_init(), hence it is not required to call it before them. This
patch removes these spurious calls.
Since we don't install libraries anymore, it makes no sense to keep
versioning them according to the gstreamer's version.

This patch fixes several issues found when running the `make distcheck`
target:
- In commit c561b8da, the update of gstcompat.h in Makefile.am was
forgotten.
- In commit c5756a91 add the simple_encoder_source_h in EXTRA_DIST was
forgotten.
- vpx.build.stamp is not generated at all, only vpx.configure.stamp.
- The make target distcleancheck failed because some autogenerated files
were not handled with the DISTCLEANFILES variable.
Note: `make distcheck -jXX` is not currently supported.
Add a cosmetic change to replace VAAPI buffer with VA buffer and most
importantly fix warnings spitted out during build on 64-bit platforms.
../../tests/simple-encoder.c:211:5: warning: format ‘%d’ expects argument of type ‘int’, but argument 4 has type ‘gssize’ [-Wformat=]
g_warning ("Invalid VAAPI buffer size (%d)", size);

This patch adds a simple-encoder test program that uses libgstvaapi for video
encoding to elementary (raw) streams. Input stream is raw YUV in the Y4M
format. That can be from a regular file or standard input when the input
filename is "-".
Usage: simple-encoder [options]* <source>
Options:
--output|-o output file name
--codec|-c codec to use for video encoding
--bitrate|-b desired bitrate (kbps)
By default, and as an initial patch, the encoded stream shall conform to the
minimally supported profile. That is "Constrained Baseline Profile" for H.264
and "Simple Profile" for MPEG-2. Though, those are the defaults to be
generated by libgstvaapi.
You can find Y4M sample files here http://samples.mplayerhq.hu/yuv4mpeg2/

The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.
Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.
This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

This library was intended to add the base classes for video decoders which
where not included in gstreamer-0.10.
Since the support of gstreamer-0.10 is deprecated those classes are not
required, thus the whole library is removed.

Add initial support for EGL to tests. The new EGL backend can be selected
through the --egl command line option. The OpenGL|ES version can further
be selected with the --gles-version command line option, where the default
of 0 means "desktop" OpenGL.
Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.
This is an API/ABI change, and SONAME version needs to be bumped.
GstVaapiTexture is a generic abstraction that could be moved to the
core libgstvaapi library. While doing this, no extra dependency needs
to be added. This means that a GstVaapitextureClass is now available
for any specific code that needs to be added, e.g. creation of the
underlying GL texture objects, or backend dependent ways to upload
a surface to the texture object.
Generic OpenGL data types (GLuint, GLenum) are also replaced with a
plain guint.
https://bugzilla.gnome.org/show_bug.cgi?id=736715
The gst_vaapi_texture_put_surface() function is missing a crop_rect
argument that would be used during transfer for cropping the source
surface to the desired dimensions.
Note: from a user point-of-view, he should create the GstVaapiTexture
object with the cropped size. That's the default behaviour in software
decoding pipelines that we need to cope with.

Replace gst_vaapi_display_get_{decode,encode}_caps() APIs with more
more convenient APIs that return an array of GstVaapiProfile instead
of GstCaps: gst_vaapi_display_get_{decode,encode}_profiles().
Replace gst_vaapi_display_get_{image,subpicture}_caps() APIs, that
returned GstCaps, with more convenient APIs that return an array of
GstVideoFormat: gst_vaapi_display_get_{image,subpicture}_formats().
Fix deinterlacing flags to make more sense. The TFF (top-field-first)
flag is meant to specify the organization of reference frames used in
advanced deinterlacing modes. Introduce the more explicit flag TOPFIELD
to specify that the top-field of the supplied input surface is to be
used for deinterlacing. Conversely, if not set, this means that the
bottom field of the supplied input surface will be used instead.
Don't try to create pixmaps if we have not requested that feature. This
fixes execution for non-X11 backends, and most specifically DRM video
output mode.
Add --deinterlace option to enable deinterlacing through explicit VA/VPP
deinterlacing filter. However, if --deinterlace option is not set but the
--deinterlace-flags option is set with "top-field-first", then the very
basic bob deinterlacing filter is set through VA/VPP proc pipeline flags.
Add --denoise option to enable noise reduction with the level specified
as the option value (float). Likewise, add --sharpen option to enable
sharpening.

Add support for frame cropping through the --crop-rect|-c argument.
The format used is either <WIDTH> 'x' <HEIGHT>, with origin at (0,0) ;
or full specification with '('? <X> ',' <Y> ')'? <WIDTH> 'x' <HEIGHT>.
Add image_generate_full() function to create interleaved color rectangles.
If flags is zero, the whole frame is generated with a unique pattern. If
flags is non-zero, then each field is handled individually.
On some platforms, vaPutImage() would fail even if it does not involve
color format conversion or scaling, whereas copying raw pixels through
vaDeriveImage() could work instead.
Add --pixmap option to test-decode so that to allow copies of VA
surface to an intermediate pixmap and rendering from that pixmap.
Only X11 backends are supported for now.
Fix new internal video format API, based on GstVideoFormat, to not
clobber with system symbols. So replace the gst_video_format_* prefix
with gst_vaapi_video_format_ prefix, even if the format type remains
GstVideoFormat.
Get rid of GstCaps to create surface/image pool, and use GstVideoInfo
structures instead. Those are smaller, and allows for streamlining
libgstvaapi more.
Change generic decoder of sample I-frame to return a GstVaapiSurfaceProxy
instead of a plain GstVaapiSurface. This means that we can now retrieve
the frame cropping rectangle from the surface proxy, along with additional
information if ever needed.
Improve check for display cache infrastructure. In particular, for X11 and
GLX backends, we need to make sure that we can create a GstVaapiDisplayX11
from another GstVaapiDisplayGLX, i.e. underlying X11 and VA displays can be
shared. Besides, allocating a GstVaapiDisplayGLX while a GstVaapiDisplayX11
already exists will have to generate different VA displays.
Introduce a new configure option --with-gstreamer-api that determines
the desired GStreamer API to use. By default, GStreamer 1.0 is selected.
Also integrate more compatibility glue into gstcompat.h and plugins.
Use gst_vaapi_image_format_from_structure() helper in test-display and
then extract a VAImageFormat from it instead of relying on GstCaps for
YUV and RGB formats.
Set the window size to the decoded surface dimensions, if the user has
not requested the application to run in full-screen mode. Besides, no
effort is made to preserve aspect ratio or to center the video within
the mapped window.
Add helper functions to determine the codec type from a specific file
or utility functions to convert from codec type to GstCaps or from
codec name to codec type.
Add the necessary helpers in GstVaapiDisplay to determine whether subpictures
with global alpha are supported or not. Also add accessors in GstVaapiSubpicture
to address this feature.

Align gst_vaapi_decoder_get_surface() semantics with the rest of the
API. That is, return a GstVaapiDecoderStatus and the decoded surface
as a handle to GstVaapiSurfaceProxy in parameter.
This is an API/ABI change.
GstVaapiSurfaceProxy does not use any particular functionality from
GObject. Actually, it only needs a basic object type with reference
counting.
This is an API and ABI change.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.
Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
