Floating point division by zero is not an error (as av_q2d performs), and in these cases the wrong return value is likely harmless. What is the actual error you are trying to fix? - Hendrik _______________________________________________ ffmpeg-devel mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
