Is it legal to build chromium embedded framework for commercial use with the following environment variable set:
set GYP_DEFINES=proprietary_codecs=1 ffmpeg_branding=Chrome

If the answer is positive, why were the official builds from http://opensource.spotify.com/cefbuilds/index.html not done like that to support MP3?

Thanks

You must have a license from MPEG LA to distribute binaries with proprietary codecs enabled.

Is there other option other than FFmpeg to support MP3?

Not via the audio tag, but you could play mp3s using OS functions or third-party libraries such as Flash.

Thank you for response.

MP3 support is very critical as more and more games are developed using HTML5. How should I change CEF3 to allow it to use windows functions to play MP3?

You would need to implement mp3 playback in your own application.

Looks like the official build supports ogg vorbis by default. Am I right?

Yes. http://http://html5test.com is a good resource if you have questions about supported media formats.
