SOLVED: Trickplay Permissions Issue

[roughnecknine0]

I'm having an issue with Trickplay image generation that I believe is due to permissions but I can't seem to figure out how to fix it.

Setup is Jellyfin in it's own LXC, media is on a drive that's mounted to my host & bind-mounted to the container, and I have the Jellyfin setting "Save trickplay images next to media" enabled for all libraries.

I believe I have UID/GID mappings correct because in my Jellyfin LXC I am able to create test.txt files on the media drive without issue.

Abridged log is here

I believe I fixed my issue. When I was testing I was using user root with UID/GID 0, however Trickplay Image Generation runs as user Jellyfin with UID/GID 110. I adjusted ownership on the drive and am now running the scheduled task to see if it works.
