• issue with ffmpeg split mp3 file into ts file(s)

  19 octobre 2016, par KenKenKen

  So I’m trying to split the mp3 file I have into .ts files using ffmpeg. Here’s the command I’m using :

  ffmpeg -i test.mp3 o1.ts

  The test.mp3 is a 28 seconds long audio.
  Then I created a m3u8 file, output.m3u8, with the following content :

  #EXTM3U
  
  #EXT-X-TARGETDURATION:30
  
  
  
  #EXTINF:28.000,
  
  http://localhost:8000/o1.ts

  Here’s the folder structure
  

  Then from command I started a local http server to serve these files

  python -m SimpleHTTPServer 8000

  I entered http://localhost:8000/output.m3u8 into the vlc player, but it doesn’t play it. So what’s the problem with my steps here ?

  Thanks

• how to merge a mp3 file into a mp4 file with low framerate(0.5) using FFmpeg wrapped in javacv

  21 février 2016, par hychanbb

  The video is with no sound only image and frame rate is 0.5, i want to merge a mp3 file into it, but it seem not work at all. Below it the code

              File folder = Environment.getExternalStorageDirectory();
  
              String path = folder.getAbsolutePath() + "/DCIM/Camera";
  
              long millis = System.currentTimeMillis();
  
              videoPath = path + "/" + "test_sham_"+millis+".3gp";
  
              try {
  
  
  
              //audio grabber
  
              FrameGrabber grabber2 = new FFmpegFrameGrabber(folder.getAbsolutePath()+"/Samsung/Music/Over_the_horizon.mp3"); 
  
  
  
              //video grabber
  
              FrameGrabber grabber1 = new FFmpegFrameGrabber(path+"/20140527_133034.jpg"); 
  
                  grabber1.start();
  
                  grabber2.start();
  
                recorder = new FFmpegFrameRecorder(path
  
                        + "/" + "test_sham_"+millis+".3gp",  grabber1.getImageWidth(), grabber1.getImageHeight(),2);
  
                  recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
  
                  recorder.setFormat("3gp");
  
                  recorder.setFrameRate(frameRate);
  
                  recorder.setSampleRate(grabber2.getSampleRate());
  
                  recorder.setVideoBitrate(30);
  
                  startTime = System.currentTimeMillis();
  
                  recorder.start();
  
  
  
                  Frame frame1, frame2 = null; 
  
  
  
                  while ((frame1 = grabber1.grabFrame()) != null || 
  
  
  
                        (frame2 = grabber2.grabFrame()) != null) { 
  
  
  
                      recorder.record(frame1); 
  
  
  
                      recorder.record(frame2); 
  
  
  
                  } 
  
                  recorder.stop(); 
  
                  grabber1.stop(); 
  
                  grabber2.stop(); 
  
                  System.out.println("Total Time:- " + recorder.getTimestamp());
  
  
  
              } catch (Exception e) {
  
                  e.printStackTrace();
  
              }

  I do the above and find out that the video contains no sound. Anyone knows how to deal with the framerate problem...
