You should be able to get these from huffman.c in the dv-encoder sample.</DIV> <DIV>Anyway, this code is so messy that youd better start from scratch..</DIV> Tue, 27 Jan 2004 10:00:46 GMT https://community.intel.com/t5/Intel-Integrated-Performance/DV-Decoder-Sample/m-p/973275#M20746 Intel_C_Intel 2004-01-27T10:00:46Z Re: DV Decoder Sample https://community.intel.com/t5/Intel-Integrated-Performance/DV-Decoder-Sample/m-p/973276#M20747 The sample provided is more or less unusable, unfortunately. Most of the samples, even if not a robust implementation, provide a good starting point. This is not one of them.
