I wish I could go back to contribute more, but work has taken all my

The advantage of the Fire TV is that it's totally out of sight. It's
plugged to the HDMI port of my LG TV and powered by USB from the TV
The shield wouldn't allow me to do that which with a TV attached to a
wall is problematic.

I'm up to about -500ms audio shift ; and 650ms read-ahead. There
doesn't appear to have been much changes to how the decoding loop is
processed and if we reach the end of the audio buffer things will
start to stutter badly and it never recovers.

I don't get that with the MediaCodec decoder, but then there's
terrible tearing happening.
Interestingly though, the CPU usage is rather similar between
MediaCodec and ffmpeg ; about 60% on all 4 cores when watching h264
1080i content
