going through AwContents makes no sense here

can some java class from media/base/android expose this method instead?

[Tima Vaisburd, 2016/07/23 00:07:27]

Thank you, will do. 

[Tima Vaisburd, 2016/07/23 03:50:58]

Hm, I could not find a good place in media/base/android either. Now put it in
MediaCodecUtils. Shall I create a new Java class, e.g. MediaInfo?
Chris, Frank, WDYT?

i think that MediaCodecUtils is fine.  if we don't have any more methods similar
to this in the future, then there's no problem.  otherwise, we can pull them out
into a separate class then, when it's clearer what their common theme is.
