[FFmpeg-devel] [PATCH] lavu/tx: support in-place FFT transforms

2021-02-10 Thread Lynne
This commit adds support for in-place FFT transforms. Since our internal transforms were all in-place anyway, this only changes the permutation on the input. Unfortunately, research papers were of no help here. All focused on dry hardware implementations, where permutes are free, or on software i
