本文详细解析了音视频编解码过程中的关键参数及其应用，通过实例展示了如何使用x264命令进行高效编码，并深入探讨了编码过程中POC（Picture Order Count）与帧间预测的关系。同时，提供了编码命令的使用技巧，帮助开发者优化视频文件大小与质量。

h->fdec->i_poc =
h->fenc->i_poc = 2 * (h->fenc->i_frame - h->frames.i_last_idr);

printf("\n h->fenc->i_poc = %d \n \n ",h->fenc->i_poc);//zjh

    h->fdec->i_type = h->fenc->i_type;
    h->fdec->i_frame = h->fenc->i_frame;
    h->fenc->b_kept_as_ref =
    h->fdec->b_kept_as_ref = i_nal_ref_idc != NAL_PRIORITY_DISPOSABLE;

用命令编码一序列，命令中用到了选项keyint

x264 --crf 22 --keyint 20 -o test.264 hall_cif.yuv 352x288

printf(n h-fenc-i_poc = d n n ,h-fenc-i_poc); - 加菲 - .

D:\>x264 --crf 22 --keyint 20 -o test.264 hall_cif.yuv 352x288
