All MIME types supported by MediaRecorder in Firefox and Chrome?

Question

Where can I find a list of all MIME types that are supported by Firefox or Chrome? All examples I\'ve seen so far using video/webm onl

Answer 1

MediaRecorder support for common audio codecs:

MediaRecorder.isTypeSupported('audio/webm;codecs=opus'); // true on chrome, true on firefox => SO OPUS IT IS!
MediaRecorder.isTypeSupported('audio/ogg;codecs=opus'); // false on chrome, true on firefox
MediaRecorder.isTypeSupported('audio/webm;codecs=vorbis'); // false on chrome, false on firefox
MediaRecorder.isTypeSupported('audio/ogg;codecs=vorbis'); // false on chrome, false on firefox

Firefox used Vorbis for audio recording in the 1st implementations but it moved to Opus since.

So OPUS it is!
