We should work on libavfilter NOT libmpcodecs. Filters should be ported
to libavfilters not cleaned up in libmpcodecs thats time wasted on a "going
to be removed" system.
thats then even adding more burden on me to merge idiotic cleanup back and
forth between libavfilter/libmpcodecs and mplayer
About regression tests, the idea is not bad if someone wants to do it. But
Asking to do that (unrelated) work as condition for this patch feels a bit
offensive IMHO. Ive not seen others make unrelated requests since a long time
and i have even asked for help many times and there are
important issues id like to work on like the malloc/free speed issue.
I prefered the past where comments where based on technical issues and not
philosophical ones. And where maintainers could work on their code without
everyone bikesheding every change.
