Image corruption with playback of 10bit videos on RPi4 LE11

Hi

I'm having image corruption in the form of blocks of pixels when playing 10bit videos on RPi4 LE11

Playback works fine in Kodi on my laptop, so it's not the video file nor kodi.

On RPi4 LE11 this plays without any issues:

Stream #0:0: Video: h264 (High), yuv420p(tv, bt709/unknown/unknown, progressive), 1280x720 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc

On RPi4 LE11 this plays with corrupted pixel blocks:

Stream #0:0: Video: h264 (High 10), yuv420p10le(progressive), 1280x720 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc

There is no slowdown or lag or anything. It's just that the image decoding gets corrupted.

Thank you for any help.

10 / 12 bit deinterlacing is a know issue. As a workaround, disable deinterlacing at playback menu (gear icon).

Can you try a nightly build? That has improvements for handling unusual pixel formats (like more than 8-bits/pixel).

I don't see anything in the original report about files being interlaced.

Interlaced content at 10/12-bits is incredibly rare.

You are really only talking about studio master files - nothing sold, broadcast, or streamed is in this format.

I tried that but it didn't make a difference.

I've downloaded LibreELEC-RPi4.arm-11.0-nightly-20230809-ecf5de7.img.gz and will give it a go in the next few days.

Thanks for the help.

Hi

I updated LE to LibreELEC-RPi4.arm-11.0-nightly-20230816-1d807c8.img.gz and it fixed the problem!

Thank you for the help and for LE
