title: How to enable H264 support in CEF3 latest version ?
body: <p>I have known that cef3's older version like 2623 can enable H264 support through modify chromium\src\cef\cef.gypi file.
  But in recent versions like 3071 or 3029, cef3 has removed cef.gypi file.
  I have googled this,  but what I found is still through modify the cef.gypi file. 
  Since this methold  is only valid for older versions. Is there another way that I can make newer version enable H264  support ?
  Thanks very much!</p>
