You most likely need this plugin: https://support.mozilla.org/en-US/kb/open-h264-plugin-firefo...

Seems like in Firefox, H.264 in WebRTC is supported in an entirely different fashion than other kinds of H.264, like in an MP4 file.

Besides that WebRTC is a tire fire¹ on any browser, why don't you just use VP8?

Should be available everywhere.

Enabling anything with "Cisco" in its name is out of scope for many (and anyway not available on Google's mobile OS).

The problem with VP8 is it's almost never hardware accelerated, neither on the encoding nor on the decoding side, so it's undesirable. Also, the software encoder x264 is quite far ahead of libvpx vp8 in terms of the encoding cost vs bitrate vs quality tradeoffs in our testing. We really hope AV1 solves all these issues once and for all in the years to come.
