Here I have written the code in JavaScript using phonegap but unable to get video data in base64
function captureVideo()
{
navigator.device.capture.captureVideo(captureSuccess, captureError, {limit: 1});
}
function captureSuccess(mediaFiles)
{
console.log(JSON.stringify(mediaFiles));
console.log("HERE I WANT BASE64 CODE");
}
To get a data-uri from the video frame you will have to draw it onto a canvas element first (as well as making sure that CORS requirements are fulfilled).
I am not that familiar with Cordova but hopefully this will get you in the right direction:
// create a canvas element
var canvas = document.createElement('canvas'), // canvas
ctx = canvas.getContext('2d'), // context
video = document.getElementById('myVideoId'); // get video element somehow
// setup canvas dimension
canvas.width = video.videoWidth || video.width;
canvas.height = video.videoHeight || video.height;
// draw in current video frame
ctx.drawImage(video, 0, 0, canvas.width, canvas.height);
// extract data-uri
var dataUri = canvas.toDataURL(); // PNG is default, use image/jpeg for JPEG
If you need to do this many times then only set up canvas once and use the drawImage
/ toDataURL
calls when you need a frame.
Hope this helps!
