MKV files with AV1 Video play as music file (lemmy.world)

Using 18.7 right now on my Nvidia Shield. I have to stay on this version for now.

I have some MKV files that use ~~OPUS audio tracks~~ AV1 Encoding, and KODI plays them as music files with no video. The files play without problems with VLC for Android.

Has anyone seen this before? Was ~~OPUS~~ AV1 support so new in Leia that the video player didn't bother with it?

EDIT: The issue was with the AV1 codec, which wasn't added to Kodi until v19.x (software), or really fully-implemented until v20.x

See my comment below for some additional detail

Thanks for the reply!

I don't have the means to re-encode now, unfortunately. I'm away from all hardware, just a laptop I'm prohibited from installing software on.

Here's the Media Info from VLC on the laptop:

Format : AV1 Format
YUV Chroma subsampling : 4:2:0
Bit depth : 10 bits

The video is AV1 format, which might not work with your shield which would be what I surmise is the problem

I was able to confirm that Kodi v19.5 can play these files (though stuttering due to software decoding), and v20.x can play them smoothly. I'll have to work to get my old, incompatible add-ons working in v20.x or live without them.

Thanks again for your insight and expertise.

Thanks for the help! I'll see what the rest of my local library is and what alternative media formats are available.

Thanks again!
