#3921: Faster RDFT -------------------------------------+----------------------------------- Reporter: ubitux | Owner: Type: enhancement | Status: new Priority: wish | Component: avcodec Version: git-master | Resolution: Keywords: fft rdft | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+----------------------------------- Comment (by kurosu): Would ne nice to have a (short) sample program or a FFmpeg command line, ie anything needed to just measure the test case. I haven't looked but isn't the reason for this slowness the use of atypical lengths. IIRC audio codecs may have specifical short windows (max 2048 samples?). -- Ticket URL: <https://trac.ffmpeg.org/ticket/3921#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
