gstreamer-vaapi consists in a collection of VA-API based plugins for
GStreamer and helper libraries. These libraries are used for hardware
decoding and encoding of several video formats.
decoding formats:
JPEG, MPEG-2, MPEG-4:2, H.264 AVC, H.264 MVC, VP8, VC-1, WMV3, and HEVC.
encoding formats:
MPEG-2, H.264 AVC, H.264 MVC, JPEG, VP8, HEVC
The package won't compile without at least one renderer enabled, so I
chose to enable DRM by default, as X11, GLX, and wayland are heavy
handed with the dependencies. As such, I have disabled every option
defaulting to yes except for DRM for the first patch.
Also, these codecs are only for x86 and require a Intel CPU (See Hardware
Requirements on line 82 of the README file.)

+Subject: [PATCH] O_CLOEXEC needs _GNU_SOURCE defined
+
+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.

+ vaapi<CODEC>dec is used to decode JPEG, MPEG-2, MPEG-4:2,
+ H.264 AVC, H.264 MVC, VP8, VC-1, WMV3, HEVC videos to VA
+ surfaces, depending on the actual value of <CODEC> and the
+ underlying hardware capabilities. This plugin is also able
+ to implicitly download the decoded surface to raw YUV
+ buffers.
+
+ vaapi<CODEC>enc is used to encode into MPEG-2, H.264 AVC,
+ H.264 MVC, JPEG, VP8, HEVC videos, depending on the actual
+ value of <CODEC> (mpeg2, h264, etc.) and the hardware
+ capabilities. By default, raw format bitstreams are
+ generated, so the result may be piped to a muxer, e.g. qtmux
+ for MP4 containers.
+
+ vaapipostproc is used to filter VA surfaces, for
+ e.g. scaling, deinterlacing (bob, motion-adaptive,
+ motion-compensated), noise reduction or sharpening. This
+ plugin is also used to upload raw YUV pixels into VA
+ surfaces.
+
+ vaapisink is used to render VA surfaces to an X11 or Wayland
+ display. This plugin also features a "headless" mode (DRM)
+ more suited to remote transcode scenarios, with faster
+ throughput.
