I use ffmpeg to decode x264 720P stream from a IP camera,
av_open_input_file(&pFormatCtx, url, NULL, 0, NULL) works well,
parameter url could be a RTSP://host address or the pathfilename save by my
program metion in the mail,only question left is: I cannot control the
displaying frame rate now,i wondered if someone could help me.

thanks a million!!
