# Sunxi-Cedrus libVA Backend
|
|
|
|
## About
|
|
|
|
This libVA backend is designed to work with the Sunxi-Cedrus VPU kernel driver,
|
|
that supports the Video Engine found in most Allwinner SoCs.
|
|
|
|
## Status
|
|
|
|
The Sunxi-Cedrus libVA backend currently only supports MPEG2 video decoding.
|
|
|
|
## Instructions
|
|
|
|
In order to use the Sunxi-Cedrus libVA backend, the `sunxi_cedrus` driver has to
|
|
be specified through the `LIBVA_DRIVER_NAME` environment variable, as such:
|
|
|
|
export LIBVA_DRIVER_NAME=sunxi_cedrus
|
|
|
|
A media player that supports VAAPI (such as VLC) can then be used to decode a
|
|
video in a supported format:
|
|
|
|
vlc path/to/video.mpg
|
|
|
|
