Hi devs,
I know this has been discussed forever but i think more and more
broadcasters are transmitting mixed frames to conserve bandwidth leading
to spamming in mythtv logs (ok, so i can turn verbosity down) when the
deinterlacer is turned on and off constantly:

As there seems to be no fix for this except by manually (not good for
WAF) turning progressive detection off via the menu, i'm happy to submit
some sort of temporary bandaid to turn off detection if the rate of
toggling exceeds a certain threshold within a 10s period (or something
like that). This seems to be happening on more and more channels and
becoming somewhat an irritation with jerky motion making me and the
family dizzy.
Have i missed some post which tells me how to fix this or am i
approaching this the wrong way ? Any comments welcome.
Thanks
D
