  • How Opensl es on android control the audio speed ?

    6 décembre 2013, par user1882379

    I use NDK+FFMPEG on android to decode an video file, and transfer the decoded pcm data to opensles for play audio .I register the opengles for the pcm format：

      SLDataFormat_PCM format_pcm;
    
    format_pcm.formatType = SL_DATAFORMAT_PCM;
    
    format_pcm.numChannels = channel;
    
    format_pcm.samplesPerSec = rate * 1000;
    
    format_pcm.bitsPerSample = SL_PCMSAMPLEFORMAT_FIXED_16;
    
    format_pcm.containerSize = SL_PCMSAMPLEFORMAT_FIXED_16;

    also I convert the decoded pcm data to AV_SAMPLE_FMT_S16 format using swr_convert(...), but the play audio speed is very fast. but if you use sdl , the play speed is normal. It would be sdl can control the play audio speed, but opensles can not. I do not know whether it is my mistake using opensles or opensles can not control audio speed(need application to control)？

  • How to implement Java methods in Nativescript ?

    6 septembre 2017, par Mike Wazowski

    I’m having trouble calling some methods of an Android java library for ffmpeg. I think I successfuly loaded the library because I can console.log the library object :

    JS: BuildConfig -> function () { [native code] }
    
JS: ExecuteBinaryResponseHandler -> function () { [native code] }
    
JS: FFmpeg -> function () { [native code] }
    
JS: FFmpegExecuteResponseHandler -> function () { [native code] }
    
JS: FFmpegLoadBinaryResponseHandler -> function () { [native code] }
    
JS: LoadBinaryResponseHandler -> function () { [native code] }

    This is the code I want to "translate" (under Usage)

    This is how far I got (using this nativescript guide) :

    // [...]
    

    
var MyCustomLoadBinaryResponseHandler = 
    
com.github.hiteshsondhi88.libffmpeg
    
.LoadBinaryResponseHandler.extend({
    
  onStart: function() {
    
    console.log('Started loading ffmpeg');
    
  },
    
  onFailure: function() {
    
    console.log('Failed loading ffmpeg');
    
  },
    
  onSuccess: function() {
    
    console.log('Successfully loaded ffmpeg');
    
  },
    
  onFinish: function() {
    
    console.log('Finished loading ffmpeg');
    
  }
    
});
    

    
console.dir(MyCustomLoadBinaryResponseHandler);
    
//^ this logs the following
    
//~ JS: === dump(): dumping members ===
    
//~ JS: "()function () { [native code] }"
    
//~ JS: === dump(): dumping function and properties names ===
    
//~ JS: extend()
    
//~ JS: null()
    
//~ JS: === dump(): finished ===
    

    
var context = app.android.context;
    

    
var ffmpeg = 
    
com.github.hiteshsondhi88.libffmpeg.FFmpeg.getInstance(context);
    

    
console.dir(ffmpeg);
    
//^ this logs the following
    
//~ JS: === dump(): dumping members ===
    
//~ JS: {
    
//~ JS:     "constructor": "constructor()function () { [native code] 
    
//}"
    
//~ JS: }
    
//~ JS: === dump(): dumping function and properties names ===
    
//~ JS: constructor()
    
//~ JS: concatenate()
    
//~ JS: execute()
    
//~ JS: getDeviceFFmpegVersion()
    
//~ JS: getLibraryFFmpegVersion()
    
//~ JS: isFFmpegCommandRunning()
    
//~ JS: killRunningProcesses()
    
//~ JS: loadBinary()
    
//~ JS: setTimeout()
    
//~ JS: <init>()
    
//~ JS: clone()
    
//~ JS: equals()
    
//~ JS: finalize()
    
//~ JS: getClass()
    
//~ JS: hashCode()
    
//~ JS: notify()
    
//~ JS: notifyAll()
    
//~ JS: toString()
    
//~ JS: wait()
    
//~ JS: === dump(): finished ===
    

    

    
ffmpeg.loadBinary(
    
  new MyCustomLoadBinaryResponseHandler()
    
);
    

    
var MyCustomExecuteBinaryResponseHandler = 
    
com.github.hiteshsondhi88.libffmpeg
    
.ExecuteBinaryResponseHandler.extend({
    
  onStart: function() {
    
    console.log('Started running ffmpeg');
    
  },
    
  onProgress: function(thisMessage) {
    
    console.log(' ffmpeg running');
    
    console.log(thisMessage);
    
  },
    
  onFailure: function(thisMessage) {
    
    console.log('Failed running ffmpeg');
    
    console.log(thisMessage);
    
  },
    
  onSuccess: function(thisMessage) {
    
    console.log('Successfully run ffmpeg');
    
    console.log(thisMessage);
    
  },
    
  onFinish: function() {
    
    console.log('Finished running ffmpeg');
    
  }
    
});
    

    
//this is where it crashes
    
ffmpeg.execute('-version', new 
    
MyCustomExecuteBinaryResponseHandler());</init>

    Unfortunately, the whole app crashes with no error message the app and I can’t continue unless I have more information on what is going on. Am I implementing the methods in a wrong way ? How do you suggest I continue ?

    edit : these are the last logs on the console
