CEF Forum

Now that the primary patents covering MP3s and AC-3 have expired, is it possible to get support for them in CEF? I'm not sure if there are other extenuating circumstances, but I figured with the majority of the patents expiring or expired, some form might be possible.

Good question. I think we'll need to wait and see what the lawyers decide. If Google ships with MP3 enabled in Chromium then we can ship it enabled in CEF as well.

Any updates on that?

Im trying to build version of cef with mp3 support but no other proprietary codecs?
I have not found any information on that in the Internet.
What I managed to find in cef souces is that if you leave USE_PROPRIETARY_CODECS flag true but comment AddContainerWithCodecs line for aac codecs, then https://html5test.com/ shows mp3 codec avaliable only
Can it be the temporary solution for the case I need mp3 only and dont need any other proprietary codecs?

Would be happy to have any piece of advice for that

Google has decided not to enable mp3 support by default for Chromium. See https://groups.google.com/a/chromium.or ... wGRjdOAQAJ

Just update from same thread:
And as luck would have it, the lawyers had forgotten to send their update, so now I have an update to share: We'll be enabling mp3 in M62 for Chromium builds. Hope this helps!
Chromium's issue: https://bugs.chromium.org/p/chromium/is ... ?id=746579

Great news!

This version of the CEF3 binaries were supposed to have MP3 support but the html5test.com page indicates that it's still unsupported in cefclient.

The link fddima gave with the Chromium's issue is unclear if we'll have to wait for the 63 stable release or some future update to the current branch.

Correct, it is currently unclear. Watch the Chromium issue for updates.

With the following comment on Chromium's issue tracker: https://bugs.chromium.org/p/chromium/is ... 746579#c12

As Chris notes in c#10, in M64+ MP4 and MP3 are available in Chromium. While the container will demux and the codec will now play, we're still sorting out the mime-type issues though so canPlayType/isTypeSupported aren't accurate.

Can we expect MP3 support out of the box in 3282?

3282 branch is M64. See https://bugs.chromium.org/p/chromium/is ... 746579#c20 for what is supported.
