The code decididing pix fmts is in libavutil av_find_best_pix_fmt_of_2() and code using that (if i guess correctly where the choice is made) so its not swscale that decides what to use [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Complexity theory is the science of finding the exact solution to an approximation. Benchmarking OTOH is finding an approximation of the exact
