hevc decoding issues questions

hi, as i have some applications i may ask here if someone has an idea what could cause this and if there is a solution.

its about DVB hevc broadcasts and often fails to decode in hw with ffmpeg.

i experience this in several apps like tvheadend, plex, emby, ...

sample failures are

tvheadend
vaapi: decode: unsupported pixel format: yuv420p10le

encoding to h265 as note working fine

plex
[Transcoder] [hevc @ 0x6f2080] PPS id out of range: 0
[Transcoder] [hevc @ 0x14af040] Could not find ref with POC -48
[Transcoder] [eac3_eae @ 0x14e0d40] Sample rate 0 invalid
[Transcoder] Error while processing the decoded data for stream #0:1
...

my source are either DVB-C or DVB-S streams coming from tvheadend, i also tested with filtering subs, teletext on/off, made no difference ...

when i look for these failures there are alot of entries, but nothing i could understand to work with.

may someone here had experience with these beaviors.

hardware is as note intel i7-8700 UHD630

and, mkv movie files are working ...

for an tipp thanks ahead
