Unable to view stream from Firefox

[tessssaract]

Firefox: 130.0.1
OS: Fedora 40 Silverblue

After starting a stream at https://b.siobud.com/ (stream key), the video does not display on Firefox, though the audio does. The stream works on my Android phone (also using Firefox), other devices outside of my home network, and on Chromium (on the same computer). Firefox has no issues streaming video from other sites (Youtube, Jellyfin, Bluesky, etc.), so I'm not sure what specifically about Broadcast Box would be an issue?

Please let me know if there is other information I could provide to help in troubleshooting. Thanks!

I have this issue as well, except it doesn't show the video on my phone either. In particular, when using AV1 or HEVC, this occurs, h.264 works normally. I get the issue on both a local host as well as https://b.siobud.com/api/whip.

As far as I know, Firefox currently doesn't support AV1 or HEVC in WebRTC. Only H264, VP8 and VP9 is supported according to Mozilla. H265 won't be supported anyway, caused by licensing issues. See https://developer.mozilla.org/en-US/docs/Web/Media/Formats/WebRTC_codecs
