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
+ * `vaapidecode' is used to decode JPEG, MPEG-2, MPEG-4, H.264, VC-1,
+ WMV3 videos to video/x-vaapi-surfaces surfaces, depending on the
underlying HW capabilities.
- * `vaapiconvert' is used to convert from video/x-raw-yuv pixels to

video/x-vaapi-surface surfaces.
+ * `vaapidownload' is used to convert from video/x-vaapi-surface
+ surfaces to video/x-raw-yuv pixels.
+
+ * `vaapipostproc' is used to postprocess video/x-vaapi-surface
+ surfaces, for e.g. deinterlacing.
+
* `vaapisink' is used to display video/x-vaapi-surface surfaces to
screen.
Features
--------
- * VA-API support from 0.29 to 0.31
+ * VA-API support from 0.29 to 0.32
+ * JPEG, MPEG-2, MPEG-4, H.264 and VC-1 ad-hoc decoders
* OpenGL rendering through VA/GLX or GLX texture-from-pixmap + FBO
+ * 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)
Software requirements
- * libgstreamer0.10-dev >= 0.10.0
- * libgstreamer-plugins-base0.10-dev >= 0.10.16
- * libva-dev >= 0.31.0-1+sds9 (VA/GLX)
- * libavcodec-dev >= 0.6 or with <libavcodec/vaapi.h>
+ * GStreamer 0.10.x:
+ libglib2.0-dev (>= 2.28)
+ libgstreamer0.10-dev (>= 0.10.36)
+ or with GstBaseSink::query()
+ libgstreamer-plugins-base0.10-dev (>= 0.10.36)
+ libgstreamer-plugins-bad0.10-dev (>= 0.10.22.1)
+ or with GstVideoContext, GstSurfaceBuffer, codecparsers
+
+ * Renderers:
+ DRM: libva-dev (>= 1.1.0), libdrm-dev, libudev-dev
+ X11: libva-dev (>= 1.0.1)
+ GLX: libva-dev (>= 1.0.3)
+ Wayland: libva-dev (>= 1.1.0), libwayland-dev (>= 0.95.0)
Hardware requirements
* AMD platforms with UVD2 (XvBA supported)
* Intel Eaglelake (G45)
- * Intel Ironlake (HD Graphics)
+ * Intel Ironlake, Sandy Bridge and Ivy Bridge (HD Graphics)
* Intel Poulsbo (US15W)
+ * Intel Medfield or Cedar Trail
* NVIDIA platforms with PureVideo (VDPAU supported)
Usage
-----
+ VA elements are automatically plugged into GStreamer pipelines. So,
+ using playbin2 should work as is. However, here are a few alternate
+ pipelines constructed manually.
+
* Play an H.264 video with an MP4 container in fullscreen mode
$ gst-launch-0.10 -v filesrc location=/path/to/video.mp4 ! \
qtdemux ! vaapidecode ! vaapisink fullscreen=true

-Caveats
--------
-
- * No ad-hoc parser, vaapidecoder currently relies on FFmpeg
+ * Play a raw MPEG-2 interlaced stream
+ $ gst-launch-0.10 -v filesrc location=/path/to/mpeg2.bits ! \
+ mpegvideoparse ! vaapidecode ! vaapipostproc ! vaapisink
