Hardware transcoding does not work for some vertical videos about immich

Yes. It should be fixed once we upgrade to FFmpeg 7.0. jellyfin-ffmpeg's relevant PR was merged recently, so that might be possible soon.

Can you attach a sample file so we can reproduce the problem?

@aviv926 the above sample can reproduce the problem on my end.

Edit: I have also attached the ffmpeg log for the sample and my vainfo

It seems this is an issue with AMD devices in particular. Intel supports 4096x4096 and I can't see a limit on this for Nvidia. I also don't know if it affects discrete AMD GPUs or just APUs, and if there are different limits for different APUs.

All in all, it might be worth rotating for VAAPI only, but needs more investigation as to the surface area of the issue and how much of a performance hit it would be for devices that don't need this.

Could this issue be on VAAPI itself? According to the datasheet for my Phoenix iGPU there should be 8k encode, decode support for h265 8/10 bit

https://patchwork.freedesktop.org/patch/577299/ - I believe this is related.

That does look related. I think we can wait for that to make its way into an FFmpeg release.

Is this still an issue?
