Please take into account that your YUV data may actually be YCbCr, the format is the same, but the scaling differs. With YCbCr the values range from 16-235 (analog standard) instead of the standard 0-255 range in the world of computers. If you are certain you are converting from/to the correct format, then you probably found a bug, but it is more likely that you are doing the wrong conversion, since the symptoms you describe fit a situation where you would have YCbCr data and interpret it as if it was YUV data on a 0-255 scale. - Arjan _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
