I am trying to play a picamera in raspberry pi 4 using vlc with raspivid/raspistill. When I give a command: sudo raspivid -o cam.jpg then some errors come,

mmal: mmal_vc_component_enable: failed to enable component: ENOSPC
mmal: camera component couldn't be enabled
mmal: main: Failed to create camera component
mmal: Failed to run camera app. Please check for firmware updates

    have you enabled the raspberry pi camera port in raspi-config?

  • Are you using the latest Raspbian Buster fully updated? Is it a genuine Pi camera?

  • Why are you using sudo? Using the camera doesn't need sudo. Also run vcgencmd get_camera to check it's enabled.

  • Hello...Yes, I have enabled a camera using "sudo raspi-config". Also, I am using a latest updated RPi4 Buster. Also run vcgencmd get_camera that show me "supported=1 detected=1". This means my picamera is enabled.

The camera is probably running out of GPU memory. Check config.txt in the /boot/ folder. The gpu_mem option should be at least 128.
