It's been working perfectly for months.

I've verified that the videos are playable in-browser natively, that they are accessible to the host and that they are mounted and accessible to the container via docker exec.

I've verified the same behaviour from a brand new docker instance (virgin config, db, temp files).

Server logs (optional)
I can provide logs, but having run the debug log and attempted to play the video, nothing of any relevance appeared in them.

Environment (please complete the following information):

Hey - I had the same issue trying to run 1.9.0 release but when I switched to 2.0.0 release it worked. I was running native with nodejs though, not in docker.

[drwb]

I'm running 2.0.0 as well. Moving from :edge-debian-bullseye to :latest and nuking everything seems to have fixed it.

[rhatguy]

This same thing happened to me. I thought something was wrong with my videos or something so I wiped the complete tmp directory before finding this. I tried moving back to :latest and completely wiping everything, but it still seems broken for me. I've started rebuilding all of my thumbnails and re-converting all of my video. That will take a couple of days.

This is broken in the demo also so something has clearly gone wrong with the app

I'll try to do some more testing once I have everything rebuilt.

[bpatrik]

Thanks for the report. i will look into it.

It seems the app by mistake servers the thumbnail instead of the original (or converted) video file. The issue is probably with the routers order (see routers folder on the backend src folder)

[rhatguy]

Just wanted to update that my PiGallery2 (running edge-debian-bullseye) auto-updated last night and this fix corrected the issue for me. Super thanks for @BluSyn for the fix and @bpatrik for the awesome app!
