+上面不行，JPEG可能是为了静态抓图，而不是mjpg, 设置回YUYV
+gst-launch-1.0 v4l2src device=/dev/video2 !  "video/x-raw,format=YUYV,width=640,height=480" !  videoconvert !  video/x-raw,format=I420 !  autovideosink
+gst-launch-1.0 v4l2src device=/dev/video2 ! capsfilter caps="video/x-raw,format=YUYV,width=640,height=480" !  videoconvert !  autovideosink
+尝试mjpg，还是要设置回jpeg
+gst-launch-1.0 v4l2src device=/dev/video2 !  image/jpeg,width=640,height=480 !  jpegdec !  videoconvert !  autovideosink

+  上面不行，就用专用转换方案
