Overview
gstreamer-vaapi consists in a collection of VA-API based plugins for
GStreamer and helper libraries.
- * `vaapidecode' is used to decode MPEG-2, MPEG-4, H.264, VC-1, WMV3
- videos to video/x-vaapi-surfaces surfaces, depending on the
- underlying HW capabilities.
+ * `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.
- * `vaapiconvert' is used to convert from video/x-raw-yuv pixels to
- video/x-vaapi-surface surfaces.
+ * `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 display video/x-vaapi-surface surfaces to
- screen.
+ * `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.

+Usage
+-----
+
+ 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
+ constructed.
+
+ * 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
