Gstreamer1.0图像保存

本人利用gst-launch-1.0 -v v4l2src ! jpegenc ! filesink location=test.jpg 只能保存一张摄像头图像,但如何把每一帧都保存为一张jpg图?

gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM), width=(int)4032,height=(int)3040, framerate=30/1' ! nvvidconv flip-method=0 ! 'video/x-raw, format=(string)I420' ! jpegenc ! multifilesink location=%05u.jpg
每一帧都会单独保存一张图片
