• FFmpeg, Icecast and ice_name in Cyrillic

  6 juin 2021, par Alexandr Kuznetsov

  Sorry for my English, I hope you can understand me.

  


  To set stream names (-ice_name), I need to use Cyrillic characters. But on Icecast server I get hieroglyphs.

  


  If I use software other than ffmpeg, then everything is displayed fine. But I need to use ffmpeg exactly.

  


  Here's the source :

  


  "c:\ffmpegrec\ffmpeg.exe" -i rtmp://... -fflags nobuffer -vn -c:a libmp3lame -b:a 192K -content_type audio/mpeg -f mp3 -ice_name "Имя стрима" -ice_description "Описание стрима" -ice_public 0 -password ... icecast://...


  


  All this is run through a .bat file.

  


• Is it possible to stream a video from FMLE directly to an media player without a mediation of FMS ?

  7 janvier 2015, par UserOfStackoverflow

  I want to know if it is possible to stream a video from FMLE (Flash Media Live Encoder) directly to an media player without a mediation of FMS (Flash Media Server) since I don’t want to restream it to many users ?

  Here is schematics of what I want (I hope it better explains my question) : http://s12.postimg.org/x4glz1l59/My_Scheme.png

  If it is possible then what media player(s) can do that ?

  Also if you know more tool like FMLE (Flash Media Live Encoder) or FFmpeg which can be controlled over command line please let me know !

  P.S.
  Thank you for your answers and suggestions also I hope that you like my drawing skills... :D

• Merging mp4 and mp3 on Android using FFmpeg

  4 janvier 2015, par user3568918

  i am developing a video capturing Android App.
  My Goal is to merge the captured Video file with a given mp3 audio file. I am using FFmpeg to merge the files. The capturing is done with the Android.Media Framework.
  If i now try to merge the files like descripted here :

  How to multiplex mp3 and mp4 files in Android

  i get the error : avcodec_open2() error -1: Could not open video codec.

  Is there a way to convert the captured video file in a readable version for FFmpeg ?
  Or is there any other way to solve this issue ?

  i Dont want to capture the video with FFmpeg, caus this will be to much complex and not clean (for my opinion)

  Hope that any body can help :)
  thanks in advance.

  I Capture like propsed in the android DOC :

  http://developer.android.com/guide/topics/media/camera.html

  and this is how i try to merge

      FrameGrabber grabber1 = new FFmpegFrameGrabber(videoPath);
  
      FrameGrabber grabber2 = new FFmpegFrameGrabber(audioPath);
  
      grabber1.start();
  
      grabber2.start();
  
      FrameRecorder recorder = new FFmpegFrameRecorder(OutputPath,grabber1.getImageWidth(), grabber1.getImageHeight(), 2);
  
      recorder.setFormat("mp4");
  
      recorder.setVideoQuality(1);
  
      recorder.setFrameRate(grabber1.getFrameRate());
  
      recorder.setSampleRate(grabber2.getSampleRate());
  
      recorder.start();
  
      Frame frame1, frame2 = null;
  
      long timestamp = -2;
  
      int count = 0;
  
      boolean isFirstTime = false;
  
      boolean isFirstCheck = true;
  
      while ((frame1 = grabber1.grabFrame())!=null) {
  
          //frame1 = grabber1.grabFrame();
  
          frame2 = grabber2.grabFrame();
  
          recorder.record(frame1);
  
          recorder.record(frame2);
  
      }
  
      recorder.stop();
  
      grabber1.stop();
  
      grabber2.stop();
  
      }catch (org.bytedeco.javacv.FrameGrabber.Exception e) {
  
          e.printStackTrace();
  
      } catch (Exception e1) {
  
          e1.printStackTrace();
  
      }
