MEDIA.getDuration() returns -1 if MEDIA.play() never been called at least once about cordova-plugin-media HOT 10 OPEN

Done, the bug remains.

1. You didn't mention before that you are working with a file that was just created with captureAudio.
2. Why should this make a difference? The relevant part here is that you create a new Media object with a path to a certain file. If this plugin doesn't actually read the file data until you call play() - then it just can't know the duration. You will have to check this plugin's code to understand when it is reading the file to get the duration.

If the current state then is not what you want, create a new issue and suggest this to be implemented or best create a PR yourself.

I have a solution to get the correct duration after recording on iOS:

After below line:

Add:

        [self prepareToPlay:audioFile withId:mediaId];
        double duration = round(audioFile.player.duration * 1000) / 1000;
        [self onStatus:MEDIA_DURATION mediaId:mediaId param:@(duration)];

What platform? What platform version?
What device were you testing on? What OS version was that running?
What version of the plugin?

What is MEDIA? Do you mean Media?

@janpio
platform android(v7.0.0 ) on "HTC One A9" & "Samsung galaxy A7" , both android nougat and 5.0.2 plugin version.
sorry for mistake, yes Media is true. (include recorded voice and video in this case).

Then first update your cordova-android to the current version 7.1.1 to make sure this is not fixed already.

Documentation says:

media.getDuration
Returns the duration of an audio file in seconds. If the duration is unknown, it returns a value of -1.

Is it possible that the data is actually not available before play was executed? When is the file actually requested/loaded?

from cordova-plugin-media.

I tried different ways,data should not available "onSuccess"? working version is like:

 navigator.device.capture.captureAudio(onSuccess, onError, options);

   function onSuccess(mediaFiles) {
      var  path,recordedVoice,stat,interval,;
     
       path = mediaFiles[0].fullPath;
       recordedVoice = new Media(path, function(){console.log("well played!")}, function(e){console.log("error:"+e)},function(status){stat=status});
      
       recordedVoice.play();
       recordedVoice.pause();

         document.getElementById("playBTN").addEventListener("click",()=>{
           var constant=100/(recordedVoice.getDuration()*10);
///etc..

Yes, I think that's a need, thanks a lot.

I have a solution to get the correct duration after recording on iOS:

After below line:

cordova-plugin-media/src/ios/CDVSound.m

Line 777 in b1c1353

// no callback - that will happen in audioRecorderDidFinishRecording

Add:

        [self prepareToPlay:audioFile withId:mediaId];
        double duration = round(audioFile.player.duration * 1000) / 1000;
        [self onStatus:MEDIA_DURATION mediaId:mediaId param:@(duration)];

Nice catch zhang! I don't know how to do it, but a pull request for this would be great
