Cordova Ionic - Read a video file and get Base64 data

I am working on a project where i need to get a base64 data from the file in Android and IOS platforms. I tried a lot but i dont get base64 data of a video file. Can anyone suggest a working method?

$cordovaCapture.captureVideo(options).then(function (videoData) { $cordovaFile.readAsDataURL(videoData[0].localURL) .then(function (success) { console.log("==========success=========="); console.log(success); }, function (error) { console.log("==========error=========="); console.log(error); }); }
