I just updated my RPi3 to LibreELEC v8.0.1 MR.

Then tried to play some 1080p HEVC clips that played poorly before the update. There is some improvement but the playback is still jerky.

I suspect the clips might be 10 bit and not 8 bit. But how can I find out?

Use mediainfo. Get a 10-bit and 8-bit sample file then query them:

Code:

wget http://jell.yfish.us/media/jellyfish-3-mbps-hd-hevc-10bit.mkv
wget http://jell.yfish.us/media/jellyfish-3-mbps-hd-hevc.mkv

mediainfo --inform="Video;%BitDepth%" jellyfish-3-mbps-hd-hevc-10bit.mkv
10
mediainfo --inform="Video;%BitDepth%" jellyfish-3-mbps-hd-hevc.mkv      
8

10-bit HEVC won't play at all. If they are playing jerky they will be 8-bit.

For 1080p HEVC you really want to overclock. Something like:

Code:

arm_freq=1300
gpu_freq=500
over_voltage=4
sdram_freq=580
over_voltage_sdram=5
sdram_schmoo=0x02000020

works on a lot of Pi's (but is not guaranteed) and will significantly help HEVC playback.
If it crashes then reduce arm_freq and sdram_freq a little.

To be safe back up the sdcard before experimenting with overclock.
