Green screen with just a hint of content on some videos

Help and Support Vero 4K / Vero 4K +

Recently my Vero4K started to exhibit a symptom where some videos consistently show green rectangle instead of video. Audio works fine, menu works fine.

Some videos play (consistently) fine
Some videos have this (consistently)

It worked before but I’m not aware of any change which could have caused it.

Please advise.

I’d recommend checking that your system is up to date

Version shown is OSMC December 2021 2021-12.1 or some such.

Update process says there are no updates available.

Have you tried playing the Jellyfish clip from local storage?

I just tried it - it looks exactly same - that is - most of the time it’s a green screen with an occasional flicker of content as jellyfish over nfs as in my video referenced in original post.

6

Is there a chance you can try with a fresh install of OSMC?

Thanks

I reinstalled OSMC completely and no luck. Same symptoms.

Are you still able to reproduce the issue with Jellyfish?

Yes I am.

Interestingly, it blinks even with playback paused: see new video here: iCloud

I tried playing with it a bit more.
Observation:

h.264 and mpeg content plays fine
h.265 shows this green screen (sometimes content is flickering through a bit, sometimes a bit more)

Even old h.265 files, which I remember being playable (on this same player) a while back exhibit this symptom.

The decoder use in player process is am265-hw, which I think is the one which should be used.

Any ideas on what could be wrong? I can’t wrap my head around it …
Also, I can’t see in h265 specific settings … are there any?

No. That jellyfish plays OK here. @tanio99 might like to look at this

And you could try a testing kernel - I sent you a link.

Are those videos remuxes?

I’m not sure - how do I find out?
