Only a minor problem found with the bitstream. However the reconstructed samples provided by the author of the bitstream are incorrect (see email). ---------------------------------------------------------------- Dear Thierry, Dear Video Conformance Testing AHG members, This is to report that I have decoded bits_conf_lep_11, and I have the following remarks: 1) In sequence_header(), I find an illegal aspect_ratio_information (8). 2) I am not able to get a perfect match with your reconstructed frames. 2.090% % of the pels have a mismatch of +-1. Once again, this mismatch may be explained by the fact that you did not use a floating-point implementation of IDCT to produce this bitstream. I think that it is better to use floating-point IDCT to produce bitstreams (ans reconstructed frames) for Video Conformance Testing. Unfortunately this point not mentionned in the AHG report produced in Paris. I will document these problems and put this bitstream on the tape.
