• Web page with script

  28 avril 2017, par Peter

  please be patient with me, I have never been very much into the coding (only at the university just a little) but here is one thing I would love to have. I havent done any research before asking before I dont even know what to search for :) but here is what I would like to do :

  I have synology device with multicast TV stream connected to it. I have installed ffmpeg and everytime I want to record a TV show I have to do it from CLI so I was thinking it would be nice to run this ffmpeg from the web page. I mean I would click the TV channel from the drop down menu, set the name of a file, set the time and click RUN and then the command (ffmpeg -i http://MULTICAST_STREAM-variable -acodec copy -vcodec copy /var/services/homes/xxx/NAME_OF_TV_SHOW.mpg) will execute on my synology...Is something like this possible ? (I hope it is)...What exactly should I search for ?

  Thank you very much

• Stopping FFMPEG from failing if one output fails

  10 septembre 2022, par Devin Dixon

  I am writing a service that is using FFMPEG to send an RTMP to multiple services. A simple example is such :

  


  ffmpeg -re -i rtmp://localhost:1935/live/xxxxxx -vcodec copy -acodec copy -attempt_recovery 1 -max_recovery_attempts 5 -drop_pkts_on_overflow 1 -f flv rtmp://a.rtmp.youtube.com/live2/xxxxxx -f flv rtmps://live-api-s.facebook.com:443/rtmp/xxxxx


  


  For the above example, occasionally the Facebook output fails and FFMPEG stops all streams. Is there a way to have ffmpeg not stop if one output fails ?

  


• Error running exec() for FFMPEG in Android app

  28 juillet 2015, par Douglas Anunciação

  When following this tutorial : https://github.com/cine-io/android-ffmpeg-with-rtmp and after compiling successfully in Ubuntu 14.04 64-bits I get an IOException when trying to execute ffmpeg :

  String abspath = getApplicationInfo().nativeLibraryDir;
  
  
  
          // Change the permissions
  
          try {
  
              Runtime.getRuntime().exec("chmod -R 777 "+ abspath).waitFor();
  
          } catch (InterruptedException e) {
  
              e.printStackTrace();
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }
  
  
  
          String cameraPath = "/storage/emulated/0/DCIM/Camera/";
  
          String cmd = "ffmpeg -i "+ cameraPath + "VID_20150728_150045662.mp4 -y "+ cameraPath + "output.mp4";
  
  
  
          ProcessBuilder processBuilder = new ProcessBuilder(cmd);
  
  
  
          final Map environment = processBuilder.environment();
  
  
  
          environment.put("LD_LIBRARY_PATH", getDir("lib", 0).getAbsolutePath());
  
  
  
          try {
  
              Process process = processBuilder.start();
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }

  And the IOException is :

  Error running exec(). Command : [ffmpeg -i

  Does anyone knows the solution for this problem ?
