[12:18:48 CET] <durandal_1707> atomnuker: how to reduce ssd calculation overlap?
[13:47:08 CET] <atomnuker> I'd grab a pen and paper, figure out which parts of the buffer each step uses for 2 small sizes and see what the pattern is
[22:37:05 CET] <cone-223> ffmpeg 03Michael Niedermayer 07master:2d580d727cf2: avcodec/gdv: Optimize unscaled loop
[23:29:25 CET] <ubitux> any reason why the avutil blend api isn't used in the overlay filter?
[23:30:02 CET] <ubitux> i was looking for some kind of blend utils for the subtitles overlay and naively checked vf overlay but it seems not to be using any shared code
[23:30:13 CET] <ubitux> otoh i'm seeing ff_blend_rectangle & friends
[23:30:24 CET] <ubitux> maybe the pixel format support differing?
[23:43:01 CET] <durandal_1707> overlay code is optimized
[23:45:11 CET] <ubitux> and i guess transfering the optimization from lavfi to lavu would complexify the code?
[23:45:28 CET] <ubitux> actually the drawutils are in lavfi
[23:45:35 CET] <ubitux> from overlay to drawutils
[23:45:50 CET] <ubitux> complexify the api*
[23:48:02 CET] <durandal_1707> special vs generic
