I am trying to enable mp3 support in CEF 3.3239.1697.g4c795f5 in OSX Sierra. I typed the following sequence of commands.

set CEF_USE_GN=1 
set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome
python /Users/myusername/Projects/cef_src/automate-git.py
--download-dir=/Users/myusername/Projects/cef_src/v1 --no-release-build --x64-build

The binary (cefclient) was built but if I open html5test.com, it says mp3 is not supported.

I believe you actually didn't set any flags, because set is not the correct command to do that (set is for Windows batch, not Linux/OSX). I'm not quite sure about OSX, but I believe you need to do something like this:

export CEF_USE_GN=1
export GN_DEFINES="is_official_build=true proprietary_codecs=1 ffmpeg_branding=Chrome"

Not sure you need the quotes there. Please also see my response here.

Make sure to set the magic flags in both scripts: update.bat and create.bat.

Some info on MP3 and OSX here. Quote: We have approval from legal to go ahead and move mp3 into non-proprietary codecs list; lets go ahead and do this for the M62 ffmpeg roll.
