Cannot open RTMP stream with FFMPEG Java Cannot assign requested address

Question

I am trying to open an RTMP stream with avformat_open_input and for some reason i keep getting Cannot assign requested address error.
My RTMP URL is correct because i can watch the stream using VLC Player and ffmpeg command line:
ffmpeg -i rtmp://1.1.1.1/app/teststream -vcodec copy -acodec copy output.mp4

int timeout = 2500;
setConnectionTimeout(timeout);

AVDictionary optionsDictionary = new AVDictionary();

String timeoutStr = String.valueOf(this.timeoutMicroSeconds);
av_dict_set(optionsDictionary, "timeout", timeoutStr, 0);

int analyzeDurationUs = 1500 * 1000;
String analyzeDuration = String.valueOf(analyzeDurationUs);
av_dict_set(optionsDictionary, "analyzeduration", analyzeDuration, 0);

int ret;

if ((ret = avformat_open_input(inputFormatContext, streamUrl, null, optionsDictionary)) < 0) {
  // ERROR Cannot assign requested address
}

I am using org.bytedeco:ffmpeg:5.1.2-1.5.8 (ffmpeg-5.1.2-1.5.8.jar)

Why i can't open it?

Answer 1

just pass null as optionsDictionary if its rtmp. ffmpeg backwards comp is not the best
