Playback of AV1 videos encoded with AOMEnc not possible - Flyk3 - 2023-12-08

I am currently experimenting with AV1, using StaxRip for encoding and the following guide for the settings.
I can play the finished test videos with VLC or MPC without any problems, but not in Kodi. The video simply won't play there. There is no error message, the overview of the videos is still displayed.
I have enabled debugging in Kodi, but the only noticeable thing I can find is the following line: ffmpeg[0x2165c693550]: [av1] Failed to get pixel format.

However, this only affects videos that I have encoded with AOMEnc, SvtAv1Enc encoded videos work in Kodi. Remux with MKVToolNix or output as MP4 with MP4Box does not work either.

Since I can play the videos with other players, I suspect Kodi is the cause of the problem. I have already reinstalled it, unfortunately without any improvement.

I hope you can help me here. I have uploaded an example video to test whether it is just my system. This is only a part of the free video "Big Buck Bunny", so it is completely legal.

Here are the encoder settings used in StaxRip: 
StaxRip encoder settings:

Try with:

Code:
--enable-keyframe-filtering=1

FFmpeg not supports keyframe-filtering=2, is a know issue:
Quote:--enable-keyframe-filtering=2 is a bit more efficient than mode 1, and doesn't suffer from the blocking bug. However, it breaks muxing with ffmpeg and may break seeking with some players. It can still be muxed correctly with mkvmerge. Test any set-top players or browsers you care about your file working in before using this setting. If you only plan to play it back locally on a sane player like mpv, then you're definitely safe. You should use this if the compatibility issues aren't a factor for you.

And even using DXVA acceleration for decoding FFmpeg is still used for demuxing
