• 404 error video file (m3u8) not being read

  4 décembre 2019, par user1163234

  I am using a Java Servlet and Tomcat to create a video file(HLS-m3u8). I am using a JSP to try and view that file using a hls.js .

  CODE

   File folder = (File) getServletContext().getAttribute(req.getServletContext().TEMPDIR);
  
      File result = new File(folder, "cam.m3u8");
  
  
  
      FFmpeg ffmpeg = new FFmpeg("ffmpeg");
  
      FFprobe ffprobe = new FFprobe("ffprobe");
  
  
  
  
  
  
  
      FFmpegBuilder builder =
  
              new FFmpegBuilder()
  
                      .setInput("rtsp://xx:xx@192.168.86.00/live")
  
                      .addOutput(result.getAbsolutePath())
  
                      .addExtraArgs("-acodec", "copy")
  
                      .addExtraArgs("-vcodec", "copy")
  
                      .addExtraArgs("-f", "hls")
  
                      .addExtraArgs("-safe", "0")
  
                      .addExtraArgs("-hls_flags", "delete_segments+append_list")
  
                      .done();
  
      builder.setVerbosity(FFmpegBuilder.Verbosity.DEBUG);
  
  
  
      FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
  
  
  
      // Run a one-pass encode
  
      executor.createJob(builder).run();

  JSP

  var name;
   <%
 File folder = (File) request.getServletContext().getAttribute(request.getServletContext().TEMPDIR);
 File result = new File(folder, "cam.m3u8");
%>
   window.onload = function() {
   name = '<%= result.getCanonicalPath()%>'
       var video = document.getElementById('video-player');
       if(Hls.isSupported()) {
           var hls = new Hls();
           hls.loadSource( '<%= result.getCanonicalPath()%>');
           hls.attachMedia(video);
           hls.on(Hls.Events.MANIFEST_PARSED,function() {
               video.play();
           });
       }
       else if (video.canPlayType('application/vnd.apple.mpegurl')) {
           video.src ='<%= result.getCanonicalPath()%>';
           video.addEventListener('loadedmetadata',function() {
               video.play();
           });
       }
   }

  The file is being created at

  "/Users/ari.sprung/Library/Caches/IntelliJIdea2018.1/tomcat/Unnamed_webappRunnerSample_6/work/Catalina/localhost/ROOT/"

  When I debug the console I see an error 404 when the player tries to load the m3u8 file. I think its adding http://localhost:8080 to the address of the file. Any idea ?

• How do I allow MPEG tcp 'pull' from FFMPEG

  7 mars 2021, par Ian

  I am using FFMPEG to create a TCP MPEG-2 stream using the following inside of nginx :

  


  exec ffmpeg -i rtmp ://localhost:1935/live/$name -codec copy -g 1 -bsf:v h264_mp4toannexb -f mpegts tcp ://192.168.1.225:1235 ;

  


  I'd like to allow a client to pull a stream from this server rather than pushing to a specific address. Can I do this ?
