Hello, I’ve very specific problem with some HEVC streams from DVB-T2 in Czech republic.
The movements are - how to say - jagged, shaded, pixeladet edges, someting like partial “ghosts”.
I can provide a recording. I have following observations:
- The problem occurs only on particular streams on one particular DVB-T2 multiplex (MUX24 in Czech republic). And not always.
- It is not problem of a poor signal from antenna (perfect signal strength and quality)
- If I record the affected stream, the problem occurs also while its playback on Vero and the artefacts are always the same
- The recording is playable on PC (VLC player) without problem so stream is not “damaged”
- When I connect to Vero’s TVheadend server from PC version of Kodi (as client) the problem doesn’t occur, so I think that there is no problem with DVB-T2 signal nor TVheadend
- Similar problem is observable on my other TV box Tesla TEH-500 (Android, also with Amlogic chipset)
- It seems like some postprocessing problem of videostream - maybe incorrect deinterlace etc.
- Stream info (from ffmpeg):
Stream #0:0: Video: hevc (Main), yuv420p(tv, bt709), 960x540 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 1k tbn, 50 tbc (default)
- All other H.265 content is played correctly by my Vero.
It seems like these particular streams contains something wrong that is not 100% compatible with Amlogic HW decoding of HEVC.
Could you provide any clue how to solve this, please?
I use latest upgrade of OSMC, with Vero 4k. Output set to 1080p50 (but doesn’t matter).
