Why do I get "ioctl(VIDIOC_DQBUF): No such device" After a couple minutes of streaming my PC monitor

in flag

I am using my Raspberry PI to stream a monitor at work with real time operating details of a conveyor system. I've set up the PI with a capture card and an HDMI to DVI splitter to do so and stream using TeamViewer.

This has worked great for the past several months, but now, a few minutes after starting the stream, the video freezes and I get a repeating

[video4linux2,v4l2 @ 0xa72005f0] ioctl(VIDIOC_DQBUF): No such device

I can restart the stream by rebooting the device, but it freezes again after a couple of minutes.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
