这是上一个代码的优化，加了IDR帧编码，适合不稳定网络（如移动通信网），已产品化，基于华恒S3C6410-R2开发板采集视频并压缩为H264格式，带IDR帧，使用时.c文件要改名为cam2fb.c-This is a code optimization, plus the IDR frame coding for unstable networks (such as mobile communications network), has been product oriented, huaheng S3C6410-R2 based on development board capture and compression for the H264 video format, with IDR frames, use time. c file to be renamed cam2fb.c
