Hey again, thanks for posting this!
According to Jellyfin's Media Info tab on the movie I did this to, it worked. It got rid of the Dolby Vision layers and is now just HDR10. But now I'm having some other weirdness.
Basically, Jellyfin won't read the final file at all, it just stays on a loading screen. This happens in the web app, the android app, and findroid (findroid doesnt show a loading screen, it just gets stuck on the play/fast forward UI and greys out some buttons).
My NAS also has it's RAM eaten up entirely by Jellyfin (16gb) and the CPU spikes in usage every now and then to 50% or more. Even after I close the window, the CPU will stay around 25% usage and the RAM usage will increase, until whatever process Jellyfin is trying to do seemingly fails, freeing up the RAM, and then restarts. This CPU usage behavior only goes away when I terminate the Jellyfin app in Truenas and start it again.
VLC also won't play the final file instantly, it just reads the file from my NAS (or external SSD if I put the file on there) at 385mbps. That is, until I click a point on the timeline, then it plays the video just fine, but there is no audio. Even though there are many different audio streams I can select, and Jellyfin as well as potplayer identify them, none of them seem to output any audio. Similarly, subtitles don't seem to work either, even though they are identified.
I suspect there is something that went wrong going from the MP4 file to the final file, as the MP4 file (the file made from taking the HEVC file and putting it into the MP4 container) plays instantly and as expected in VLC. I did try and upload this file (the HEVC to MP4 file) to Jellyfin and it stuttered a ton (unless it was transcoded to 1080p 20mbps, anything higher had slight stuttering), even though it played fine in VLC. Probably because there is no audio? But just adding info in case it helps.
Just in case, here is the commands I ran (I'm running Windows 11, FFMPEG for Jellyfin 6.0.1-8-portable_win64, DoVi 2.1.2, also tried with normal FFMPEG)
