Hi, @friendtasy running a quick test of MediaSource.isTypeSupported('audio/webm; codecs="opus"'); and MediaSource.isTypeSupported('audio/webm; codecs="Opus"'); in the console and getting true for both in Win10/Chrome, same on Mac. Regardless, video.js, http-streaming and the mpd-parser do not change codec strings so this is likely a browser support issue. Can you please attach a link to a sample manifest and/or a reduced test case and I would be happy to take another look.

@friendtasy the manifest you attached seems fine to me. Are you able to test this against the branch from the PR linked above? videojs/http-streaming#1219
