Re: 2010 FRC Camera Live Feed Lag

We are haveing the same problem also, are your saying a quick fix for this problem is to run the driverstation under the developer account?

Re: 2010 FRC Camera Live Feed Lag

I found the problem to be the graphs on the right side of the dashboard were causing a huge delay. I removed them and we now get near instant video (minus expected network latency). Our fixed dashboard is here http://www.chiefdelphi.com/forums/sh...ad.php?t=81378

/\ is our solution. The graphs on the right side of the Dashboard were lagging the image considerably so we took them out of the Dashboard and the image is very fast now (only the expected network latency). The fixed Dashboard is attached

Re: 2010 FRC Camera Live Feed Lag

What do you guys mean by "logging into the camera?" Is it the Axis Camera setup? Or are we talking about logging in by navigating to its IP address (and what would that be if this is the case)?

We're talking about connecting the camera to the computer via crossover cable, setting your computer's IP & subnet to 192.168.0.99 & 255.255.255.0, and typing http://192.168.0.90 into your browser. 192.168.0.90 is the camera's default IP address.

Re: 2010 FRC Camera Live Feed Lag

I want to check to make sure that anybody having this issue has seen the latest update (this is for C/C++) that in the description says, "the camera code now is much more efficient with less copies and image buffer allocations in the library.The PC Video server (images back to the dashboard) are much faster now – it should in most cases run at the full camera rate. For image sizes of 320x240 the total lag should be around 0.5 seconds. Smaller images are lower."

If you are using windriver this might help out. I haven't seen an update like this for Labview or Java yet, although I haven't looked as hard.

Get the Updates from here: http://first.wpi.edu/FRC/frccupdates.html

Question Re: 2010 FRC Camera Live Feed Lag

I have had that problem with the camera feed. We are using the lowest resolution, we are running it in the developer account with nothing else open. it is programmed in C++. Is there anything I can do about this?

Re: 2010 FRC Camera Live Feed Lag

Are you using the new update for C++? The second issue that can cause lag is that the driver station is bogged down. You can check with the task manager.
