I'm pretty sure this is wrong, why would you need this?

But I do hit the "NOTREACHED()" check below. A test did moment ago gets the log
as:
chromium: [FATAL:ffmpeg_demuxer.cc(668)] Check failed: false. Proprietary codecs
not enabled.

The proprietary codecs, e.g. OpenH264, is not available on android. We need work
around it to utilize MediaCodec to play back H264 recording.

Done.

   InitBitstreamConverter();
 #else
   NOTREACHED() << "Proprietary codecs not enabled.";
