So we have: C++, 2xBR v3.3b, LGPL http://sourceforge.net/p/paintown/code/HEAD/tree/trunk/src/util/graphics/sdl/xbr.cpp C++, 2xBR v3.3b, GPL https://github.com/yoyofr/iFBA/blob/master/fba_src/src/intf/video/scalers/xbr.cpp The former is clearly a copy&paste from the latter, so that should be used as reference. paintown code was relicensed to GPL with Hyllian's consent, so we should be able to do the same (if licensing is a concerns, which probably isn't for such a fringe filter). Algorithm description can be found here: https://web.archive.org/web/20140904180543/http://board.byuu.org/viewtopic.php?f=10&t=2248 (note: it was down the last time I checked). NOTE: since both are games/emulators, I suppose it won't be easy to make them generate a reference output, so we should rely on comparing the output generated by the filter with some output found on the web. @arwa: are you willing to readapt your xbr filter to make use of Hyllian's code? -- FFmpeg = Freak and Frightening Maxi Powered Enhancing Gangster _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
