Chainmax : it would be possible, with a lot of time. But I don't really think it's useful, since most of the filters are working in YV12 ( except Dust ). So it's not one of my priorities yet. For what purpose would you have the use of an YUY2 version ?
K-Dash : link is working, I'll make myself clearer : right click on the link, do 'copy adress', paste it in your adress bar, it'll work ( at least it's working for me ). I emphasised that sentence in my first post.
@all : I'll be away from my computer for 2 weeks soon, so I'll cope with the most obvious bugs first ( and there are plenty ). Another version should be up for tomorrow, correcting the multiple use of a same function with different mode. ( right now, except for expand / inpand / deflate / inflate, using more than once a function with a different mode always applies the function with the same mode ).
Edit : oups, my bad, only the 4 I corrected were subject to this bug. I should have read the changelog
