• Save StreamTitle tag in recording

  29 décembre 2022, par jarno

  Some streams have StreamTitle tag set and it changes from time to time. Is that information send only when it changes in the stream ? For example in this stream StreamTitle is used to tell the artist and the name of current song :

  


  ffprobe -v error -show_entries format_tags http://st.downtime.fi/sun.mp3


  


  Is the StreamTitle tag exclusive to MP3 streams ? Can one have it in Opus streams as well ?

  


  Can such information be added to the output file created when recording the stream by ffmpeg for example, to be able to see which song is playing when playing the recording later ? Could another tag be used to tell program name which may also alter in time ?

  


• Draw on Android video and save

  23 novembre 2015, par YI YANG

  I am a beginner to the Android meida programming, so if I have any problem please tell me, thank you very much.

  Recentally, I saw an IOS version App called V1 Sports ! it allows you to record a video and then draw lines, circles or any shapes on the video. Those shapes are stored, next time when you open your video, the shapes are still there, unless you clear the shapes overlay on the video.

  I am wondering how to implement those functions on an Android deveice, it is so cool. Use ffmpeg or something like that ? I do not know where to start. Please tell me some hints Thank you very much.

  This is command string which i want to process.

  String[] command = new String[]"ffmpeg -y -i " + old_video_path + " -strict experimental -vf curves=vintage -s 240x320 -r 30 -aspect 4:3 -ab 48000 /storage/emulated/0/video.mp4" ;
  executeFFmpeg(command) ;

  private void executeFFmpeg(String[] cmd) {
  
      try {
  
          ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onStart() {
  
                  Log.e("Progress", "onStart");
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.e("Progress", "onProgress");
  
              }
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.e("Progress", "onSuccess");
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  Log.e("Progress", "onFailure" + message);
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
  
  
                  Log.e("Progress", "onFinish");
  
  
  
              }
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
