 Recently I have found that there is some pixelation when viewing certain
 channels using openmax. When viewing then using ffmpeg, that problem
 disappears. Either there are errors in the stream which are handled better
 by ffmpeg, or some mpeg2 feature is being used that is not supported by

 The raspberry pi 2 is able to sustain a 1080i stream using ffmpeg decoder
 and openmax renderer.

 I have updated the OpenMAX Normal profile to add an entry where ffmpeg is
 used for Standard Definition. I have also added "OpenMAX High Quality"
 which does ffmpeg and openmax for all resolutions.

 On raspberry pi 2, OpenMAX high Quality is fine, but has minor glitches
 with the OSD. I suspect it may work better on a raspberry pi 3.
