Description

I have kodi as client and 4k live channels works fine.
But HD HEVC channels (1920x1080) plays choppy. First 1-2 seconds plays video with sound, when picture and sound stops and plays static pictures every 5-10 secs without sound.
Recordings 4k and HEVC HD plays fine.
vls from satip server plays this channels fine.
I include log switching to hevc hd channel - "LUXURY HD"

Have you checked your client is able to play it ? it is possible that the channel use 10bit instead of the common 8bit !

Ok, somehow framerate not computed. I don't know how it computed in hevc, but after this workaround my hevc 1080 channels started working.
