WebRTC troubleshooter provides a set of tests that can be easily run by a user to help diagnose WebRTC related issues. The user can then download a report containing all the gathered information or upload the log and create a temporary link with the report result.

• Microphone
  • Audio capture
    • Checks the microphone is able to produce 2 seconds of non-silent audio
    • Computes peak level and maximum RMS
    • Clip detection
    • Mono mic detection
• Camera
  • Check WxH resolution
    • Checks the camera is able to capture at the requested resolution for 5 seconds
    • Checks if the frames are frozen or muted/black
    • Detects how long to start encode frames
    • Reports encode time and average framerate
  • Check supported resolutions
    • Lists resolutions that appear to be supported
• Connectivity
  • Udp/Tcp connectivity
    • Verifies it can talk with a turn server with the given protocol
  • IPv6 connectivity
    • Verifies it can gather at least one IPv6 candidate
  • Data throughput
    • Establishes a loopback call and tests data channels throughput on the link
  • Video bandwidth
    • Establishes a loopback call and tests video performance on the link
    • Measures rtt on media channels.
    • Measures bandwidth estimation performance (rampup time, max, average)

Due to their time duration they are not part of the normal test suite and need to be run explicitly.

• [Network latency](https://test.webrtc.org/?filter_test=Network latency)
  • Establishs a loopback call and sends very small packets (via data channels) during 5 minutes plotting them to the user. It can be used to identify issues on the network.

• Audio and Video streams
• Iframe apprtc
• Iframe video
• Multiple audio streams
• Multiple peerconnections
• Multiple video devices
• Multiple video streams
• Peer2peer
• Peer2peer iframe
• Single audio stream
• Single video stream
