江湖告急。。。ICDecompress出错问题

Question

DIV3的MPG4压缩:
    m_hIC=ICOpen(ICTYPE_VIDEO,878070084,ICMODE_COMPRESS|ICMODE_DECOMPRESS);
    if(!m_hIC)
        goto RET;
    ICCompressGetFormat(m_hIC,&m_BmpU,&m_BmpC);
    if(!ICSeqCompressFrameStart(&m_cv,&m_BmpU))
        goto RET;
    if(ICDecompressBegin(m_hIC,&m_BmpC,&m_BmpU)!=ICERR_OK)
        goto RET;
p=(char*)ICSeqCompressFrame(&m_cv,0,pin,&k,&s);再用ICDecompress总是失败。而用用ICImageCompress速度那是巨慢啊大侠帮忙啊。让小弟过个好年吧：（
