Basilisk's WebRTC cannot seem to detect my camera

Post by jobbautista9 » 2025-11-19, 13:56

So I've thought about trying out the browser's WebRTC function, and while the microphone works fine, my camera can't be detected. I'm using my Android phone as a webcam via VCamdroid. Firefox 145 can detect it just fine and offers me whether to share it.

Example URL is https://webrtc.github.io/test-pages/src/single-video/. There's nothing in the devtools and toolkit error consoles that seem relevant to my issue.

Has anyone been able to get Basilisk to detect a webcam?

This is a known bug. libvpx encoding/decoding in WebRTC broke at some point between Moonchild's last release of Basilisk and my first release of Basilisk. I have not been able to determine what change caused this to break. WebRTC services that do not use libvpx do work including webcam with Basilisk, but unfortunately almost all services use libvpx.

Hmm I wonder if there's a way to force the OpenH264 plugin to be used then so it doesn't use libvpx. In https://mozilla.github.io/webrtc-landing/pc_test.html I was able to get Waterfox Classic to use the plugin (and my OS's task manager confirms that it created a plugin-container process for OpenH264) by ticking the "Require H.264 video" checkbox. But in Basilisk even with that box ticked I am not getting the prompt to share my camera.
