      如果遇到这个问题的话:

      coolpi@car-c:~$ gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=25/1 ! videoflip method=vertical-flip !  mpph264enc ! rtspclientsink latency=0 location=rtsp://192.168.0.100:554/test
      Setting pipeline to PAUSED ...
      ERROR: Pipeline doesn't want to pause.
      ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not open device '/dev/video11' for reading and writing.
      Additional debug info:

      Freeing pipeline ...
      
      

      执行命令前加上sudo,给上权限,摄像头就能用了
