Firefox can not use default mimeType to record audio #19

Closed infr closed 3 years ago

With the default mimeType video/webm;codecs=vp8 Firefox (81.0.2 tested) recording audio will fail with NotSupportedError: MediaRecorder.start: An audio track cannot be recorded: video/webm;codecs=vp8 indicates an unsupported codec.

This is a know issue in MediaRecorder API: https://github.com/w3c/mediacapture-record/issues/194
