I've done more testing and I can get the Shield TV with the 64 bit version
working okay.  The older FireTV 4K I can get to work with OpenGL only. It's
about like the v31 in quality.  However, the new FireTV Max has major
issues. With either Mediacodec or OpenGL I have to have the Audio Read
Ahead at a 1000 or higher.  It has relatively good quality with decent FSP
jitter until you try to skip forward. It might work for one or 2 skips, but
at some point it audio fails and the video looks like double frame rate,
i.e. faster than normal walking, etc. the Menu/Playback/Playback data show
the FPS at 122 but it bounces. I can't recover without ESCing back out of
the recording.
