Spotify Codecs Still Unsupported even with proprietary_codecs=true ffmpeg_branding=Chrome

[jammerxd]

Hi there,

I'm trying to make a web player for spotify that uses the spotify web sdk - my html page is fine since it works without issues in chrome and edge.

I tried using my html page to see if it'll play inside of cefsharp but the result I get in the dev tools console is this:
[0919/143916.787:INFO:CONSOLE(18)] "Uncaught NotSupportedError: Failed to execute 'addSourceBuffer' on 'MediaSource': The type provided ('audio/mp4; codecs="mp4a.40.2"') is unsupported." (18)

I am building with proprietary codecs since youtube videos play just fine within the browser.

Can someone help me figure out how to get this enabled?

Best place to ask for help building CEF is https://magpcss.org/ceforum/index.php

If you built cefclient I'd also suggest testing with that first to confirm your build is correct.

I personally haven't built a version with proprietary codecs enabled for 6+ months, maybe something changed.

I actually got the build to work - but now there's an issue with widevine - the spotify client is returning a 403 when trying to open the spotify website in the cefclient.exe sample app -

Ugh. Yep to the forums I go. This is so dumb and painful.

Looks like additional Widevine License is required.

Yes I'm the one that opened that topic - additionally I've sent multiple requests to widevine and heard nothing.

I know (you used the same username) 👍

Posting as reference for anyone else that ends up here looking for information.

Personally I'd expect a response to take weeks not days.
