<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;mso-fareast-language:EN-US">I’m currently stuck at mythtv 30 with raspi 3b frontends using openmax output; that has perfect playback for mpeg2 and h.264 up to and including 1920x1080p for recordings
from DVB and DVB-S2 <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;mso-fareast-language:EN-US">The reason I’m stuck at v30 is that openmax output was removed with 31, and I couldn’t get acceptable playback with pi3 or pi4 – decoding and menu speed was ok, but
I’d always get tearing, particularly noticeable on horizontal pans.<o:p></o:p></span></p>

tearing issue on either system. (but does use about twice as much cpu)<o:p></o:p></span></p>
