Question

I need to know the duration of a video captured via PhoneGap before uploading to the server. The documentation for the MediaFile.getFormatData is a little vague and doesn’t seem to be working.

I have been able to successfully capture and upload a video, so all of that is working, just the duration part isn’t.

What am I doing wrong?

Running on an iPhone 4 with iOS 5.1.1

navigator.device.capture.captureVideo(function(mediaFile) {
        if(mediaFiles.length == 1) {
            $('#video_url').val(mediaFiles[0]);
            var profileVideo = document.getElementById('profile-video');
            profileVideo.src = mediaFiles[0].fullPath;

            var formatData;
            mediaFiles[0].getFormatData(function(data) {
                formatData = data;
            });

            if(formatData.duration > 30) {
                $('#infoMessage').html("Your video is longer than the allowed 30 seconds. Please record a new video. You can trim your video after it's been recorded.")
            }
        }
    }, function(error) {
    }, null);

Answer 1

You are trying to call async code in an synchronous manner. Try it like this instead:

mediaFiles[0].getFormatData(function(data) {
    if(data.duration > 30) {
        $('#infoMessage').html("Your video is longer than the allowed 30 seconds. Please record a new video. You can trim your video after it's been recorded.")
    }
});
