IMHO not really. FFT is a fairly core part of FFmpeg, so I don't believe 100% depending on an external solution is an option. So we still need to reasonably maintain our implementations. > It is even available on windows AFAIK, since Julia uses it. I'd like to point out that I would only use the word "even" for Solaris, OS/2, Haiku or BeOS support. I think Windows, Linux, BSD and OSX support count as "basic OS support" for us. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
