Yes. I can't get any Dolby Vision files to play at all on my device. MP4 or MKV doesn't work.

I thought I would jump in, just to confirm. I added in the Plex ffmpeg patch to a fresh git pull of Kodi and compiled for my 2019 Shield. I was able to verify the patch was included, but it is not enough to make DV work with MKV. That said, the mp4 DV does work fine for me.

I'll gladly try any future patches, but probably won't do any dev work myself.
