RetroOrangePiZero 4.1 NTSC - mpv not using vdpau #24

Open yam001 opened 6 years ago

yam001 commented 6 years ago

Trying to use kodi to play video from the setup, it can only play for 5 minutes until the CPU temperature reaches 76 degree C and the system stops responding. I did a htop from a putty session and I noticed during video playback all 4 CPUs were 100% busy and the mpv threads were using --vo=x11. Shouldn't this be --vo=vdpau? Also in /etc/mpv/mpv.conf, vo is set to vdpau but its been ignored. May be this is reason why the CPU temperature was so high? Is hardware decoding supported in this release? BTW, thanks for the great work here.

I was only using air-cooling with a raspberry pi heat sink on the CPU. Having to use active cooling would defeat the purpose of this SBC.

kodi reads VO info from ~/.kodi/userdata/playercorefactory.xml and it's set to x11 because vdpau wont work on analog / lower resolutions (black screen). I'm not sure if this is a driver limitation. Anyway, avoid videos higher than current resolution (something like 672x448), otherwise it will push CPU to downscale the video. You can also try the builtin player, it seems to have good performance (press C prior to playing the video).
