13 gstreamer-vaapi helper libraries and plugin elements are available

20 gstreamer-vaapi consists in a collection of VA-API based plugins for
21 GStreamer and helper libraries.
23 * `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4:2, H.264 AVC,
24 H.264 MVC, VP8, VC-1, WMV3 videos to VA surfaces, depending on the
25 underlying hardware capabilities. This plugin is also able to
26 implicitly download the decoded surface to raw YUV buffers.
28 * `vaapiencode_<CODEC>' is used to encode into MPEG-2, H.264 AVC,
29 H.264 MVC, JPEG, VP8 videos, depending on the actual value of
30 <CODEC> (mpeg2, h264, etc.). By default, raw format bitstreams
31 are generated, so the result may be piped to a muxer.
32 e.g. qtmux for MP4 containers.
34 * `vaapipostproc' is used to filter VA surfaces, for e.g. scaling,
35 deinterlacing (bob, motion-adaptive, motion-compensated), noise
36 reduction or sharpening. This plugin is also used to upload raw
37 YUV pixels into VA surfaces.
39 * `vaapisink' is used to render VA surfaces to an X11 or Wayland
40 display. This plugin also features a "headless" mode (DRM) more
41 suited to remote transcode scenarios, with faster throughput.
47 * VA-API support from 0.29 to 0.37
48 * JPEG, MPEG-2, MPEG-4, H.264 AVC, H.264 MVC, VP8 and VC-1 ad-hoc decoders
49 * MPEG-2, H.264 AVC,H.264 MVC, JPEG and VP8 ad-hoc encoders
50 * OpenGL rendering through VA/GLX or GLX texture-from-pixmap + FBO
51 * Support for the Wayland display server
52 * Support for headless decode pipelines with VA/DRM
53 * Support for major HW video decoding solutions on Linux (AMD, Intel, NVIDIA)
54 * Support for HW video encoding on Intel HD Graphics hardware
55 * Support for VA Video Processing APIs (VA/VPP)
56 - Scaling and color conversion
57 - Image enhancement filters: Sharpening, Noise Reduction
58 - Advanced deinterlacing: Motion-Adaptive, Motion-Compensated
66 * GStreamer 1.2.x (up to including GStreamer 1.6):
67 libglib2.0-dev (>= 2.28)
68 libgstreamer1.0-dev (>= 1.2.0)
69 libgstreamer-plugins-base1.0-dev (>= 1.2.0)
70 libgstreamer-plugins-bad1.0-dev (>= 1.2.0)
73 DRM: libva-dev (>= 1.1.0), libdrm-dev, libudev-dev
74 X11: libva-dev (>= 1.0.1)
75 GLX: libva-dev (>= 1.0.3)
76 Wayland: libva-dev (>= 1.1.0), libwayland-dev (>= 0.95.0)
80 * AMD platforms with UVD2 (XvBA supported)
81 * Intel Eaglelake (G45)
82 * Intel Ironlake, Sandybridge, Ivybridge, Haswell and Broadwell (HD Graphics)
84 * Intel Poulsbo (US15W)
85 * Intel Medfield or Cedar Trail
86 * NVIDIA platforms with PureVideo (VDPAU supported)
92 VA elements are automatically plugged into GStreamer pipelines. So,
93 using playbin should work as is.
94 However, here are a few alternate pipelines that could be manually
97 * Play an H.264 video with an MP4 container in fullscreen mode
98 $ gst-launch-1.0 -v filesrc location=/path/to/video.mp4 ! \
99 qtdemux ! vaapidecode ! vaapisink fullscreen=true
101 * Play a raw MPEG-2 interlaced stream
102 $ gst-launch-1.0 -v filesrc location=/path/to/mpeg2.bits ! \
103 mpegvideoparse ! vaapidecode ! vaapipostproc ! vaapisink
105 * Convert from one pixel format to another, while also downscaling
106 $ gst-launch-1.0 -v filesrc location=/path/to/raw_video.yuv ! \
107 videoparse format=yuy2 width=1280 height=720 ! \
108 vaapipostproc format=nv12 height=480 ! vaapisink
110 * Encode a 1080p stream in raw I420 format into H.264
111 $ gst-launch-1.0 -v filesrc location=/path/to/raw_video.yuv ! \
112 videoparse format=i420 width=1920 height=1080 framerate=30/1 ! \
113 vaapiencode_h264 rate-control=cbr tune=high-compression ! \
114 qtmux ! filesink location=/path/to/encoded_video.mp4
