Add vaapipostproc element for video postprocessing. So far, only basic
bob deinterlacing is implemented. Interlaced mode is automatically
detected based on sink caps ("interlaced" field).

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.
|
|
|
|
* `vaapiupload' 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 0.32
|
|
* 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 major HW video decoding solutions on Linux (AMD, Intel, NVIDIA)
|
|
|
|
|
|
Requirements

Usage
|
|
-----
|
|
|
|
* 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
