The issue is that, when using the ffmpeg based decoder, legacympegparse is
needed.
However, when setting the rank of ffdec_mpeg2dec to PRIMARY+1, legacyparse ends
up not being selected. The solution is to remove mpeg2dec (eg, set its rank to
NONE - note that SECONDARY wasn't enough), then it all works smoothly as
legacympegparse gets used. Your patch to bump ffdec_mpeg2dec to PRIMARY+1 is
not then needed.
