// Android MediaPlayer will be used. ?

Still, I wonder if IsMediaCodecAvailable() covers all the cases. What exactly is
this handling?

I don't think we need to mention MediaPlayer here, this is after all
"MediaCodecUtil" :) I've added that comment to mime_util though.

The IsMediaCodecAvailable() method is a complete-device blacklist, whereas this
just blacklists the vp8 codec. E.g. we'll still use the MediaCodec for h264.
