The question is why? It will effectively result in nearly the same code except that picture buffer will be allocated properly. IMO codecs with such design can suffer from additional memcpy from internal buffer with stride=width*bpp to frame with whatever stride it has. _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
