Accelerated H.264 and HEVC video decoding with Cedrus

[baryluk]

For anybody wanted a try, here are quick instructions.

I am using vdpau 1.1.1-3, from Debian Stretch (aka testing) and/or Sid (aka unstable).

Code:

sudo apt-get install libvdpau-dev
git clone https://github.com/linux-sunxi/libcedrus.git
cd libcedrus/
make && sudo make install
git clone https://github.com/linux-sunxi/libvdpau-sunxi.git
cd libvdpau-sunxi
make && sudo make install
sudo ldconfig

Other pieces, like /dev/disp and /dev/cedrus_dev already exist and are set to be in the group "video". (You can check if you are in this group using 'id' command).

If you need pixman, try sudo apt-get install libpixman-1-dev , this will install pixman 0.33.6-1, and retry above script.

Then try

Code:

VDPAU_DRIVER=sunxi mplayer -vo vdpau -vc ffmpeg12vdpau,ffh264vdpau, video_file.mkv

Unfortunetly for me, it crashes after few frames of very smooth playback, and then cendrus leavs nasty video overlay with one of the frames (slightly corrupted), that I have no idea how to get rid of other than rebooting

You can add export VDPAU_DRIVER=sunxi maybe to your ~/.bashrc file, or /etc/profile.d/vdpau-sunxi.sh maybe for easier use.

Output from vdpauinfo (installed via sudo apt-get install vdpauinfo):

Code:

$ export VDPAU_DRIVER=sunxi
$ vdpauinfo
