Today in competition, we were running into an issue where our MJPG camera stream on the SmartDashboard dies every 15-20 seconds. It usually comes back after 15-30 seconds. The video is being streamed from an NVidia Jetson TK1, using a custom server. I would immediately assume that this problem is caused by this software, but I'm not so sure because it only occurs on the field network. On the SmartDashboard we get a "read timeout" error when the stream dies.

Throughout all of our testing during build season and tethered testing at competition, this has not been a problem. As far as I can remember, we never saw this problem occur during Suffield Shakedown, though we didn't use our vision system much there. It has only occurred on the field at this event

I have talked to a few of the field staff at the event and went through the DS logs to check for problems, but there wasn't much interesting there. Bandwidth usage is within acceptable limits (~3 Mbps) and there is not a lot of packet loss.

I was wondering if anyone had any suggestions to help get this working better for tomorrow, because I am at a loss to figure out what is going on. My long term solution is likely going to involve going to a UDP based streaming protocol.

Thanks.
