I'm having an odd issue when playing back 2.35:1 aspect ratio videos on my Vizio Smartcast tv (through Apple AirPlay). The video will stretch vertically to just a little wider than 16:9. I have tested the same videos on iOS, browser, and Roku, and they work fine. Oddly, I was having the same issue with Plex playback on the same tv (through native Plex app on tv), and was able to correct it by turning off direct play and direct stream. I don't see an option to force a transcode through Jellyfin, though.
I went to test this, and found I don't actually have any sample content that is 21:9. I'll have a quick look to see if any videos exist in this AR (or try to make one with FFmpeg).
