Converting Dolby Vision to HDR10

[TheDreadPirate]

Someone probably could make a plugin to do this, but I don't like the idea of Jellyfin modifying my files automatically. This is not something that can be done on the fly either.

I tried using the updated command in the first post of this thread, but I am in the Exec Console of a Jellyfin Container in Portainer on a Terramaster F4-423 NAS and I get the below error.

Code:

[out#0/matroska @ 0x560aec387200] Error opening output /movies/XXXXTest/hdr10_video.mkv: Read-only file system
Error opening output file /movies/XXXXTest/hdr10_video.mkv.
Error opening output files: Read-only file system

I tried logging in as root and then the PUID:GUID, but the same thing.

How can I get this to work?

I moved this post from the other thread.  Are you still having issues?  I'm assuming you figured out that you needed to write to a directory that wasn't read-only to the container.
