To learn the detail, you can check<BR /><BR />file: umc_h264_gen_enc_tmpl.cpp.h, function: H264CoreEncoder_Init<BR /><BR />Thanks,<BR />Chao Fri, 10 Sep 2010 07:50:44 GMT Chao_Y_Intel 2010-09-10T07:50:44Z https://community.intel.com/t5/Intel-Integrated-Performance/H-264-encoder-params/m-p/854135#M6890 Hi,<BR /><BR />In the H.264 encoder param, there is flag (the last line of the param file) that takes the values 0 to 3.<BR /><BR />3 sample.log /* speed/quality grade [0,3] (0-maximum speed, 3-maximum quality); log file name (unused) */<BR /><BR />When I check the encoder, there's another flag called ANALYSE_RD_OPT. I think that ANALYSE_RD_OPT means Rate-Distortion Optimization, but what's the use of the first flag?What's the differnece between the two flags?<BR /><BR />Thank you!
