Disable streams #1387

Open ItayNaumann opened 1 month ago

ItayNaumann commented 1 month ago

During the season, we've used photonvision, and we had bandwidth problems. We wanted to see a certain stream, but only 1 stream at a time while stopping all of the others. Not seeing the stream didn't disable it, and it took a lot of bandwidth with it.

A way to disable each one of the streams, probably via a NT entry.

Could also be cool maybe a "focus mode" for when there are a couple of cameras and wanting to show only one of the stream at a time, maybe a NT entry that uses the port's number to choose focus

If not viewing a stream doesn't decrease bandwidth, I would argue that actually a bug and we should open an issue either way to try and triage it.

How were you viewing the streams? What "app" were you using?

ItayNaumann commented 1 month ago

We were listening from the camera publisher entry in our dashboard

Juniormunk commented 1 month ago

What resolution were the streams? Are they color or gray scale?

ItayNaumann commented 1 month ago

One colorfull, one greyscale. OV 9281 and OV 9282. I think that both had a stream of 640 by 480

Which dashboard software did you use? And did you also have the web ui open at the same time?
