PhoneGap unable to getDuration() out of Media API, but other methods work

Question

I\'m building out an audio media recorder/player with PhoneGap. It\'s all working beautifully, but I\'ve hit a wrinkle I can\'t seem to iron.

my_media.play();

Answer 1

This solution works for me. Basically, play and immediately stop. It doesn't seem to take any time, seems like a decent workaround.

media.play();
media.stop();
var length = media.getDuration();

Answer 2

This question is too old. But it is still relevant because many might have been facing this same problem. Whenever nothing works I just do one thing, upgrade or downgrade the version. In this case I solved my problem by installing following version.

cordova plugin add cordova-plugin-media@1.0.1

Answer 3

I also faced similar problem in cordova for iOS. I was successfully able to record, play and stop audio but unable to get current position and total duration for audio file. So I added my_media.release() just after I was done finishing recording audio i.e. after my_media.stopRecord() and it worked like a charm. Earlier I was getting -1 for getDuration() and 0 for getCurrentPosition().

Hope it helps someone.

The metadata for the media in question has not been loaded when you call my_media.getDuration(). In the documentation you referenced in your question the example code puts the getDuration call into an interval:

var timerDur = setInterval(function() {
    counter = counter + 100;
    if (counter > 2000) {
        clearInterval(timerDur);
    }
    var dur = my_media.getDuration();
    if (dur > 0) {
        clearInterval(timerDur);
        document.getElementById('audio_duration').innerHTML = (dur) + " sec";
    }
}, 100);

I would recommend doing something similar.
