I would like to run tests on Raspberry Pi 2/3 and 4.

I assume the local build process, is the same as for Ubuntu/Debian i.e. 
install build depends using Ansible and use ./configure (no additional 
options) for mythtv.

At present on a Pi 4 (4GB) with a default install of Raspbian Buster, 
the best performance I can get is with V4L2 Codecs, but even this has 
issues particularly with HD (UK DVB-T2 ) over HDMI 1920x1080 @50Hz.

Video Playback Profile defaults to MMAL.

I maybe missing some necessary settings, there are so many possible 
options, so I would like to use the same settings as used during 
development, can anyone provide these ?

The settings needed for pi2/3 and 4 are:

mythfrontend Video Profile

any changes required to /boot/config.txt

Pi 4 default uses dtoverlay=vc4-fkms-v3d with max_framebuffers=2 i.e. 
running Fake KMS, Pi 2/3 do not use the fkms overlay.

Once I have everything working I can update the mythtv-light wiki 
page(s) for Raspberry Pi.
