    initial v1  
    11I have done some testing of this bug. It looks to me like the hardware advanced and fast deinterlace may have stopped working with the release of the RPI3. I am unable to see advanced deinterlace working at all on RPI3. Earlier versions of raspbian will not boot on the RPI3.

    3 With a small test program and lots of playing around I have found that advanced deinterlace only works with a tunneled path from decoder to deinterlacer. MythTV normally has the deinterlace as part of the video output stage. It will have to be moved to the decoding stage for the appropriate tunnel to be used. I believe this may be a bug in the raspberry pi firmware. However the deinterlace does not seem to be documented anywhere other than in forum postings, so I do not know for sure if this is intended.

     5There was a firmware change with firmware version 2d0f7ec (July 8, 2016). The nFlags now carry deinterlace information which must be passed forward with each buffer.
