Describe the bug

when i use web_cam the video will disconnect when the camera is unplugged

To reproduce

i added a bat_init() to try and see if that would allow the video to play when the camera is unplugged but it disconnects after 30 seconds

Expected behavior

i expect the camera to rely on its battery and keep streaming

So why is it so strange? This example originally displays the contents of the camera on the web page. The camera has been unplugged, indicating that a fault has occurred. Shouldn't the device stop running?
