To reproduce:
- Make a clean profile.
- Log In to browser Discord, find any post with a video file that's encoded in h264 or AVC. Not an embedded one, i.e., Youtube.
- It may show a loading icon on the top right hand side of the video, eventually it'll stop and show the sad face error picture.
Auto Play is set to Allow all auto-play.
Interestingly, video files used to work before on this version of Orion or the previous (can't quite recall). I think a Discord update must've broke something on what Orion was using to handle the files. Works OK on Firefox 115.15.0esr and Chromium.
