• configure : fix LARGEADDRESSAWARE flag with MSVC

  24 juillet 2015, par Hendrik Leppkes

  configure : fix LARGEADDRESSAWARE flag with MSVC
  Otherwise it would get translated like a library path (-L option),
  
  which breaks setting the flag.

• avutil/opencl : is_compiled flag not being cleared in av_opencl_uninit

  5 mars 2015, par Srikanth G

  avutil/opencl : is_compiled flag not being cleared in av_opencl_uninit
  When OpenCL kernels are compiled, is_compiled flag is being set for each
  
  kernel. But, in opencl uninit, this flag is not being cleared.
  
  This causes an error when an OpenCL kernel is tried on different OpenCL
  
  devices on same platform.
  Here is the patch with a fix

• How to change or modify pitch of audio file (music etc like .mp3 file)using FFMPEG ?

  18 octobre 2022, par syed kashifullah

  I want to change and modify pitch an .mp3 audio file using FFMPEG.
But I am unable to use FFMPEG to change or modify pitch of that sound.
what command (exact command) should be exactly use for changing pitch of an audio file ?

  


   String outPutPath = new File("/storage/emulated/0/Share it Application/Over_the_HorizonTemp.wav").getPath();
                 
                String[] strFfmpeg  = {"ffmpeg","-i" ,strInputPath,"-af", "rubberband=tempo=1.0:pitch=1.5:pitchq=quality" ,outPutPath};
                execffmpegBinary(strFfmpeg);


  


  execffmpegBinary Function :

  


  public void execffmpegBinary(String[] command) {
    Config.enableLogCallback(new LogCallback() {
        @Override
        public void apply(LogMessage message) {
            Log.e(Config.TAG, message.getText());
            Log.e("TAG", "apply: " +message.getText());
        }
    });
    Config.enableStatisticsCallback(new StatisticsCallback() {
        @Override
        public void apply(Statistics statistics) {

        }
    });

    long executionId = FFmpeg.executeAsync(command, new ExecuteCallback() {
        @Override
        public void apply(long executionId, int returnCode) {
            if (returnCode == RETURN_CODE_SUCCESS) {
                
                Log.e("1TAG", "apply:return code "+returnCode );
                Log.e("1TAG", "apply:execution Id "+executionId );
                Log.e("1TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));


            } else if (returnCode == RETURN_CODE_CANCEL) {
                Log.e("2TAG", "apply:return code "+returnCode );
                Log.e("2TAG", "apply:execution Id "+executionId );
                Log.e("2TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));

            } else {
                Log.e("3TAG", "apply: returnCode"+ returnCode);
                Log.e("3TAG", "apply:return code "+returnCode );
                Log.e("3TAG", "apply:execution Id "+executionId );
                Log.e("3TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));

            }
        }
    });
