Vertical videos playing horizontally

[howardh]

I have some videos filmed in portrait mode, but when I play them, they're rotated 90 degrees. Jellyfin clearly knows the correct video orientation because the automatic thumbnails are all correctly oriented. It also seems to only happen on some videos and not others. Why could that be?

It should be fixed in Jellyfin 10.10.

Ah, thanks! I updated and it's working properly now. It doesn't look like 10.10 was needed. I went from 10.8 to 10.9.11.
