gstreamer-vaapi helper libraries and plugin elements are available
under the terms of the GNU Lesser General Public License v2.1+
gstreamer-vaapi consists in a collection of VA-API based plugins for
GStreamer and helper libraries.
* `vaapi<CODEC>dec' is used to decode JPEG, MPEG-2, MPEG-4:2, H.264
AVC, H.264 MVC, VP8, VP9, 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, VP9, 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.
* `vaapioverlay` is a accelerated compositor that blends or
composite different video streams.
* VA-API support from 0.39
* JPEG, MPEG-2, MPEG-4, H.264 AVC, H.264 MVC, VP8, VC-1, HEVC and
VP9 ad-hoc decoders
* MPEG-2, H.264 AVC,H.264 MVC, JPEG, VP8, VP9 and HEVC ad-hoc
* OpenGL rendering through VA/GLX or GLX texture-from-pixmap + FBO
* Support for EGL backend
* Support for the Wayland display server
* Support for headless decode pipelines with VA/DRM
* Support for major HW video decoding solutions on Linux (AMD,
Intel, NVIDIA)
* Support for HW video encoding on Intel HD Graphics hardware
* Support for VA Video Processing APIs (VA/VPP)
- Scaling and color conversion
- Image enhancement filters: Sharpening, Noise Reductio, Color
Balance, Skin-Tone-Enhancement
- Advanced deinterlacing: Motion-Adaptive, Motion-Compensated
Hardware requirements
* Hardware supported by i965 driver or iHD, such as
- Intel Ironlake, Sandybridge, Ivybridge, Haswell, Broadwell,
Skylake, etc. (HD Graphics)
- Intel BayTrail, Braswell
- Intel Poulsbo (US15W)
- Intel Medfield or Cedar Trail
* Hardware supported by AMD Radeonsi driver, such as the list below
- AMD Carrizo, Bristol Ridge, Raven Ridge, Picasso, Renoir
- AMD Tonga, Fiji, Polaris XX, Vega XX, Navi 1X
* Other hardware supported by Mesa VA gallium state-tracker
VA elements are automatically plugged into GStreamer pipelines. So,
using playbin should work as is.
However, here are a few alternate pipelines that could be manually
* Play an H.264 video with an MP4 container in fullscreen mode
$ gst-launch-1.0 -v filesrc location=/path/to/video.mp4 ! \
qtdemux ! vaapidecodebin ! vaapisink fullscreen=true
* Play a raw MPEG-2 interlaced stream
$ gst-launch-1.0 -v filesrc location=/path/to/mpeg2.bits ! \
mpegvideoparse ! vaapimpeg2dec ! vaapipostproc ! vaapisink
* Convert from one pixel format to another, while also downscaling
$ gst-launch-1.0 -v filesrc location=/path/to/raw_video.yuv ! \
videoparse format=yuy2 width=1280 height=720 ! \
vaapipostproc format=nv12 height=480 ! vaapisink
* Encode a 1080p stream in raw I420 format into H.264
$ gst-launch-1.0 -v filesrc location=/path/to/raw_video.yuv ! \
videoparse format=i420 width=1920 height=1080 framerate=30/1 ! \
vaapih264enc rate-control=cbr tune=high-compression ! \
qtmux ! filesink location=/path/to/encoded_video.mp4
gstreamer-vaapi is Open Source software, so updates to this
framework are really easy to get.
