webrtcHacks - How to Figure Out WebRTC Camera Resolutions

I did some experiments with WebRTC's getUserMedia() constraints? This lead me down a rat hole but I had some interesting results.

Highlights include:

  • Non-obvious Findings
  • Mandatory constraints are really suggestions.
  • Kill the stream before applying new constraints.
  • Use https for a better user experience.
  • Don’t bother changing constraints in Firefox today.
  • Auto-identifying Camera Resolutions
