Can a multipart/x-mixed-replace stream be played in a webview inside javafx?

I am using a flask server to stream video from a webcam to a java client Here is the Flask implementation:

def generate():
    # grab global references to the output frame and lock variables
    global outputFrame, lock

    # loop over frames from the output stream
    while True:
        # wait until the lock is acquired
        with lock:
            # check if the output frame is available, otherwise skip
            # the iteration of the loop
            if outputFrame is None:
                continue

            # encode the frame in JPEG format
            (flag, encodedImage) = cv2.imencode(".jpg", outputFrame)

            # ensure the frame was successfully encoded
            if not flag:
                continue

        # yield the output frame in the byte format
        yield(b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + 
            bytearray(encodedImage) + b'\r\n')

@app.route("/video_feed")
def video_feed():
    # return the response generated along with the specific media
    # type (mime type)
    return Response(generate(),
        mimetype = "multipart/x-mixed-replace; boundary=frame")

I have a javafx webview screen, but it doesnt show anything. Is it because Webview does not support multipart/x-mixed-replace? Whats the solution for this? Is there any other option to get a python video stream onto a JavaFX application?
