To elaborate on what my ideas behind this patch are.
Its for libavfilter to be successfull, to have a competetive feature set and
not be an academic toy without features, not used by anyone because it lacks
the most basic filters. I want to give these features to our users ...
But i dont want this code to stay like this in SVN for ever, i do have eyes
and i do too see its not pretty but for me the cosmetic aspect is very minor.
The much bigger aspect or me is that using these filters through the wraper
is technically annoying, the APIs are far from mapping 1:1 onto each other
porting filters to libavfilter is technically a good idea not only cosmetically
and i want it to happen. But i do want to make the features available to our
users during all the time and not keep 50 filters that are ready but ugly
away from our users for 2 years. That really would be very nasty from us to do
to our users
If you want the filters ported to native quickly, theres SOC, theres code in,
theres funding by the foundation, theres contributing patches yourself or
talking other people into helping.
But i dont think a big "we will remove it in a year" is going to achive anything
a fork is easier than porting the filters. And in FOSS its "you want it, you do
it" not "you dont want it, you can prevent others from doing it"
And once someone of us is fed up enough and just forks, the official tree of
libavfilter will perish, no users, no bugreports, noone will port anything in
it. I also would leave and contribute where i can work freely without these
philosophically loaded discussions.
