Hi, I created two files using these command lines:
ffmpeg -i fcp7_xdcam_ex_1080_25p_1s.mov -vf scale=in_color_matrix=bt709:out_color_matrix=bt601 -c:v ffv1 -an scale_test_bt601.nut ffmpeg -i fcp7_xdcam_ex_1080_25p_1s.mov -c:v ffv1 -an scale_test_unscaled.nut Using framemd5 I verified that the resulting output is identical. Is this some sort of optmization of swsscale (i.e. not doing anything when size and pixel format remain unchanged)? Can it be forced to do the conversion anyway? I know that there is also vf_colormatrix but that is much more limited than swscale and it's not LGPL.
