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
