There’s a strange slideshow effect that happens when playing back 1080p and 4K HEVC content. Audio still plays back normally. BT.709 and BT.2020 are both affected.

Here’s a link of the video capture: 37.83 MB file on MEGA

Also, here is a link to a source clip: 72.5 MB file on MEGA

Thanks for making a new post.

I can see the issue.

Can you try a USB/SD image as sent via PM?

Cheers

Sam

Sure thing! I’d be happy to.

I can’t reproduce the issue either on the release kernel or the tesing kernel. Is it something to do with Plex? Can you play these videos without Plex?

I’m gonna do a clean install without addons to make sure, before I try the test image.

Edit: the slideshow effect is still present with clean install.

Edit2: the test image is a winner. It has perfect playback. Thanks for letting me try it out!

Thanks for confirming. It’ll be a little while before this hits release.
