CefSharp is a wrapper around the Chromium Embedded Framework in a lot of cases a feature must be added to CEF first before it can be used in CefSharp. CEF has its own Feature Request Forum at https://magpcss.org/ceforum/viewforum.php?f=7

They both require audio codecs that require royalties. See https://github.com/cefsharp/CefSharp/wiki/General-Usage#multimedia-audiovideo

Closing as this isn't something we can support out of the box. You have to build CEF from source.

Hi Guys,

I wanted to make Apple Music program with CefSharp, so could use the program instead of webpage.
The website loads fine exept it will not load a song. After alot of reseaching yesterday I saw that you need to enable secured content (DRM). Because I tried Spotify web player and asks to enable secure playback.

I was searching for hours and found something about WidevineCDM. But I am new to this and have no idea how it actually works. I will make a repo for this project if anyone wants to help.

Hope to hear from some of you soon!
Here are some screenshots of code and the errors.

Widevine DRM is already supported.

The default builds don't include the AAC audio codec due to licensing restrictions. So once you enabled widevine you'll find the browser is still unable to play the audio. See https://magpcss.org/ceforum/viewtopic.php?f=6&t=17917&p=47013

If Apple music uses AAC audio codec then the audio won't play.

[stevenboeren]

Is there any way to make it play that? bc on Google Chrome it just works fine. I'm 17 and just wanna try somthing since I wanna be a Software Developer.

Companies like Google and Microsoft pay licensing fees to include h264/AAC decoders in their products. CefSharp is open source, it only includes support for freely available codecs.

Your best bet is to try another browser, WebView2 from Microsoft might be a viable option.
