Accelerated H.264 and HEVC video decoding with Cedrus

[longsleep]

Starting with Kernel 3.10.65-2-pine64-longsleep-43 the media modules are included. This means one could use the hardware video engine on the SoC. So i felt why not try it - and surprisingly it worked .

Pine64 decodes 1080p H.264 and HEVC just fine and smooth with Cedrus from linux-sunxi community.

You can do it yourself following the Cedrus build instructions on http://linux-sunxi.org/Cedrus

Pine64 SoC temperature is stable at around 70C while decoding HEVC 1080p (without a heat sink, no enclosure).

For easy mplayer launches with the correct parameters feel free to use https://github.com/longsleep/build-pine6...er-play.sh


I will not support this overly much, but it confirms that the BSP Kernel has everything which is needed to use the media decoder in the Pine64.

Cheers
