I am currently trying to read an RTSP stream with FFMPEG and can't get past
avformat_open_input.

Any help would be appreciated!

thank you.

#include <libavformat/avformat.h>

int main()

    AVFrame* frame = NULL;
    AVFormatContext* formatc = NULL;

    AVCodecContext* codecc = NULL;
    char* error = new char[255];

    if (!(frame = av_frame_alloc())) {
        std::cout << " failed to alloc frame";
        return -1;
    }
    formatc = avformat_alloc_context();
    formatc->interrupt_callback = int_cb;

    codec = avcodec_find_decoder(AV_CODEC_ID_H264);
    codecc = avcodec_alloc_context3(codec);
    int result = avcodec_open2(codecc, codec, NULL);
    if (result != 0) {
        std::cout << "failed to open codec";
    }

    result = avformat_open_input(&formatc, "rtsp://:8554/testStream", NULL,
NULL);
    if (result != 0) {
        av_strerror(result, error, 255);
        std::cout << "couldnt open input " << error<< std::endl;
        avformat_close_input(&formatc);
        return -1;
    }

    result = avformat_find_stream_info(formatc, NULL);
    if (result != 0) {
        std::cout << "could not find stream information\n";
        return -1;

    return 0;
