TimeoutException after video freezes

[RusticRocket]

Steps to reproduce:

1. Run GRIP on laptop.
2. Create a new file with just a source for an IP camera.
3. Connect to robot over wireless.
4. Start previewing the image.
5. Eventually the video stream stops or freezes, usually within a minute or so.
6. Hit the "stop" button.
7. You get the stack trace below. Question is why did the video freeze to begin with. I'm not sure if something is causing it to "stop" and the stop button just isn't getting updated, or if the stream has just frozen. The interesting thing is that if we connect to the robot over ethernet, then it becomes much more stable and we can run the video stream for 15 or 30 minutes before it freezes.

Failed to stop
