记录一个.arv视频文件（测试版）

就一个给定的GVM而言，您可以随时以视频器件的原格式来记录当前GVM访问的图像。例如，使用Python语言，以Telepathe为GVM进行这一操作：


                # First launch Telepathe and display NAOCam images
                camProxy = ALProxy("ALVideoDevice", IP, PORT)
                nameId = "telepathe_videoModule"
                numberOfImagesToRecord = 100
                period = 2
                success = camProxy.recordVideo(nameId, "/home/nao/naoqi/data/myFile", numberOfImagesToRecord, period)
                # This will record 100 images in myFile.arv at half the framerate of Telepathe.
                 
                # Stop grabbing
                camProxy.stopVideo()
