h264编码程序，能够实现视频压缩，分别压缩I帧p帧b帧-ENG coding procedures, video compression can be achieved, I frame compression p frame b frame

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, huahen

simple rtsp h264 decoding class i-p-b frames are enable etc.

实现H264编解码图像文件的源代码 实现算法：baseline profile ，含H.264算法参数设置(分辨率、帧率（I/P:15-20）等）和解码后的I帧-H264 codec to achieve an image file of the source code algorithm: baseline profile, including H.264 algorithm parameter settings (resolution, frame rate (I/P :15-20),
