I am using ffmpeg as a library. how to to force it ( in the code, not commandline) use tcp?
shortly like that
int f=1;
while(av_read_frame(pFormatCtx, &packet)>=0)
        // Is this a packet from the video stream?
            // Decode video frame
            avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished,
            // Did we get a video frame?
                do work with frame
        if (f>1) break;
