Always the decoder have the official "code", that is defined by the Motion Expert Group, but not the encoding (that is the trick). Anyway, the codec is "pixel perfect", so always the decoding picture is the same, not like other codecs like MPEG2 where exist a possible iDCT algorithm and precision of this, affecting the final image decodec. If the image is corrupted in the decoding process is a faulty or buggy program issue.
