Cordova-file-plugin: file type = null after compressing video on iOS

Hi everybody,
I use Cordova-plugin-file to get video from my device. Everything work perfectly on Android. but in iOS, the file got type = null after the video is compressed on iOS device. Here is my option for the file plugin:

var options = {
                quality: 100,
                destinationType: Camera.DestinationType.FILE_URI,
                sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
                mediaType: Camera.MediaType.VIDEO,
                saveToPhotoAlbum: false

then use it like this:

                // file object
                var file = {};
                window.resolveLocalFileSystemURL(imageURI, function(fileEntry) {
                    fileEntry.file(function(fileObj) {
                        file = fileObj;
                }, function(err) {

It seems weird when the video still gets compressed when I choose quality: 100 but I still can accept that. But after being compressed, the file type is not defined (on Android it is still defined as ‘video/mp4’)
How could I resolved this ? Thank you.

I’m seeing the same thing. Ever find a solution to this?
