Dear all,

not sure if this has been addressed already: my mediabox (Zotac) has a Kaby Lake GPU (HD Graphics 620 Kaby Lake GT2).
Whenever i switched on VAAPI hardware decoding, livetv is not running smoothly anymore (input dvb-c with tvheadend backend). UHD are playing fine.
When VAAPI hardware decoding is deactivated, live tv is fine, UHD playback is stuttering. I also tried to only activate certain codecs underneath VAAPI hw decoding (i.e. HEVC only) - same result.

Player process info for live tv: h264 codec

Any ideas what I can try out?

 Post your Debug Log. This is exactly my setup where everything is fine. Besides tvheadend - recordings work?
