Phonegap：如何獲得捕獲視頻的實際寬度和高度

Question

我試圖通過手機電話獲取捕獲視頻的高度&。無論拍攝視頻時我的iPhone是縱向還是橫向，寬度/高度輸出始終爲480x360。任何想法爲什麼？

captureSuccess: function(mediaFiles) { 
    var path, mediaFile; 
    path = mediaFiles[0].fullPath; 
    mediaFile = mediaFiles[0]; 
    mediaFile.getFormatData(function(mediaFileData) { 
     console.log(mediaFileData); 
     //output for mediaFileData : {"width":480,"duration":1.478333,"bitrate":0,"codecs":null,"height":360} 
    }, function(error) { 
     console.log(error); 
    }); 
}

試試這個

$("<video/>").attr("src", "VIDEO_PATH").on('loadedmetadata', function() { 
    var dimensions = [this.videoWidth, this.videoHeight]; 
    alert(dimensions); 
});
