In general, yes. However there may be some problems with this. There 
could be MythTV changes needed, as  there were this time where a couple 
of things were renamed in FFmpeg. Also the FFmpeg patches may not always 
apply cleanly, they may need changes. In both of these situations, you 
don't know at what stage in the commits of FFmpeg code the changes are 
needed. Also, an FFmpeg branch such as release/4.4 does not follow on 
from release/4.3, but rather both are branched from master, so bisecting 
may have to be done on FFmpeg master.
