Streaming http VLCJ - Githubissues

Palak92 commented 7 years ago

I am trying to stream a video via vlcj to local host by using this code:

public class StreamHttp extends VlcjTest {
static MediaPlayerFactory mediaPlayerFactory;
    public static void main(String[] args) throws Exception {
        new NativeDiscovery().discover();     

        String options = formatHttpStream("127.0.0.1", 5555);       

        mediaPlayerFactory = new MediaPlayerFactory(args);
        HeadlessMediaPlayer mediaPlayer = mediaPlayerFactory.newHeadlessMediaPlayer();
        mediaPlayer.playMedia("screen://", options);

        Thread.currentThread().join();
    }

    private static String formatHttpStream(String serverAddress, int serverPort) {
        StringBuilder sb = new StringBuilder(60);
        sb.append(":sout=#transcode{vcodec=mp4v,vb=800,scale=0,acodec=mpga,ab=128,channels=2,samplerate=44100}:duplicate{dst=std{access=http,mux=ts,");
        sb.append("dst=");
        sb.append(serverAddress);
        sb.append(':');
        sb.append(serverPort);
        sb.append("}}");
        return sb.toString();
    }
}

But when I type IP address and port number in my browser nothing comes up.

First, please take the time to format your code in markdown correctly if you expect any help.

Second, what do you expect me to do with this limited information and without logs. Enable logs, look at the logs, if you're still stuck, post the logs.

The code is : link for code
The logs:

The Program runs but I am not able to see streamed video at this IP

I see markdown formatting escapes you.

Probably something wrong with your transcoding "sout" string.

Palak92 commented 7 years ago

I checked the string containing "sout" with vlc media player ( in streaming option ) and copied it down in my program. I rechecked the string by executing it on cmd window. It works there too. The logs dont show any issue with the string.

caprica commented 7 years ago

Enable verbose native logging in vlcj using "-vvv" in MediaPlayerFactory arguments. Play your media.

Enable verbose logging in VLC using "-vvv" on the command-line. Play your media.

Compare differences in the logs.

caprica commented 7 years ago

Put it this way, there can only be a few things that are wrong.

Either it's your MRL, "screen://" - now this on its own looks OK, but you may need to set other options.

Or it's your sout string.

Or it's some other option you need to set on the MediaPlayerFactory.

Or it's some other option you need to set on your mediaPlayer.playMedia() call.

Look at the ScreenTestPlayer.java for some properties I set when using screen:// that you don't.

It's simply impossible for me to say given what you posted that it must be x, y or z.

I tried to compare the logs. They seem to be different and massive. I think there is some issue in mux. I have attached the files. here snippet to logs-- VLC:

I have tried putting MRL as file:///C:/out2.mp4 and string a: "sout \"#transcode{vcodec=h264,vb=56,venc=x264{profile=baseline},fps=12,width=176,height=144,acodec=mp3,ab=24,channels=1,samplerate=44100}:duplicate{dst=http{mux=ffmpeg{mux=flv},dst=:8080/},dst=display :sout-keep\""
