CEF only supports open formats. For example, ogg audio plays fine:

avcodec-53.dll
avformat-53.dll
avutil-51.dll

the version is older ?

I replace them with Chrome'14. Then audio_test.html can work.

Codecs like MP3 and AAC are included in Google Chrome releases but not Chromium 
builds. This is because these formats are not open and require licensing. 
Distributing these codecs with your application without a licensing agreement 
may violate the law in certain countries. You should discuss with a lawyer if 
appropriate.

In order to use proprietary audio and video codecs in Chromium/CEF you need to:

1. Acquire ffmpeg libraries that support the proprietary codecs.
2. Add 'proprietary_codecs': 1 to your cef.gypi configuration so that 
USE_PROPRIETARY_CODECS will be defined as required by net/base/mime_util.cc.

I add that 'proprietary_codecs': 1 to my cef.gypi.
and test it with http://html5test.com it works as google chrome and chromium.

But cefclient still can't playback *.mp4 file. 
it error return code is MEDIA_ERR_SRC_NOT_SUPPORTED : 4

Hello!

I have the same problem, I want to enable proprietary codecs like MP3, MP4, 
.... . We were able to add proprietary_codecs=1 to the cef.gypi file, and 
opening the CefClient app and visiting the http://html5test.com/ website told 
that the browser support these proprietary codecs, but it failed to playback 
the files. With the instructions provided by nook from previous replies, I 
copied the libffmpegsumo.dll file from Chrome next to CefClient, and the video 
playback just worked.

How can we build the libffmpegsumo.dll with the proprietary codecs in cef? I 
see some flags that might be useful, but wasn't able to build a 
libffmpegsumo.dll with the propreitary codecs in it. 
I've tried the following flags:
        build_ffmpegsumo
        use_system_ffmpeg
                ffmpeg_branding
                ffmpeg_branding=Chrome

Thanks for the help!
Balazs
