Per Quested Aronsson created CB-1680:
----------------------------------------
Summary: Uncaught TypeError in cordova-*.js when using media API
Key: CB-1680
URL: https://issues.apache.org/jira/browse/CB-1680
Project: Apache Cordova
Issue Type: Bug
Components: CordovaJS
Affects Versions: 2.0.0
Environment: 1. Ripple, Chrome, Mac OSX 10.7.5
2. Phonegap Build, Apple iPad
Reporter: Per Quested Aronsson
Assignee: Filip Maj
Fix For: Master
When testing my code in Ripple, I get the following error and no sound plays:
```
Uncaught TypeError: Cannot set property '_duration' of undefined
cordova-2.0.0.js:3090
Media.onStatus cordova-2.0.0.js:3090
(called from anonymous function) ripple.js:477
row 3090: media._duration = value;
```
The same code tested in Phonegap Build does *not* crash. It doesn't work as
expected, but it doesn't crash. Audio playback doesn't stop when it should. The
audio file is played to the end every time.
Please find the relevant part of the code below. It will not run as is. It
expects to find an audio file of at least 8s duration at "audio/FX.m4a", and it
expects to find an HTML element with ID "cross", but that's it I think.
```javascript
function AudioPG() {
var self = this;
var soundOff = false;
var inter;
var sound = new Media('audio/FX.m4a', self.onSuccess,
self.onError);
var segmentEnd = 0.5; //sound.getDuration(); // used for sound
var sprites = { // id: [start, length], startpoints: 0,1,2,7
0: [1, 1.7], // Jackpot
1: [0.0, 0.5], // Click
2: [2.5, 5], // Whosh
3: [7.2, 7.7] // Buzz
};
this.checkSprite = function () { console.log('checkSprite');
if (segmentEnd) {
sound.getCurrentPosition(function(position) {
console.log([position, segmentEnd]);
if (position >= segmentEnd) { // getCurrentPosistion uses
seconds
sound.pause();
clearInterval(inter);
inter = null;
}
},
function(e) {
console.log("Error getting pos=" + e);
}
);
}
};
this.playSprite = function (id) {
if (soundOff) {
return;
}
var startTime = sprites[id][0];
segmentEnd = startTime + sprites[id][1];
if (sound) {
sound.seekTo(startTime*1000); // seekTo uses
milliseconds
sound.play();
if (!inter) {
inter =
setInterval(self.checkSprite,100);
}
}
};
this.stopSprite = function () {
if (sound) {
sound.pause();
}
};
this.toggleSound = function (e) {
var cross = e.target;
soundOff = !soundOff;
cross.style.opacity = (soundOff ? 0.4 : 0);
};
// onSuccess Callback
//
this.onSuccess = function () {
console.log("playAudio():Audio Success");
};
// onError Callback
//
this.onError = function (error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
};
document.getElementById('cross').addEventListener('touchstart',
self.toggleSound, false);
console.log(['AudioPG', segmentEnd]);
}
```
