I loaded small h263 videos in ffmpeg 7.0 (current) which would run
h263dec.c (I assume) and then encoded them using h264.mp4 format.  I then
did the same thing in the ffmpeg.git version (future version 8.0) where
patch8 was deleted.  Visually detected no problem and when I used the
patchbay arithmetic subtract on the 2 versions of encoded files, they
showed no anomalies.

But I completely re-run make clean,  ./autogen.sh/configure/make dance

Finally, it compiled but I am not sure what made the difference as I always
use "make clean" and then run "bld.sh" which includes "autogen.sh"; i.e. -
