frc driver station dashboard unable to open error

This works fine for streams of video, but probably not always for static images, since they'll only change if you change to a different image or mess with the pipeline at all.Īlso if you put the GRIP extension panel in the top left corner of the smart display and click on File in the menu so that the menu obscures part of the panel, and then close the menu, then the part of the image that was under the menu frequently becomes pinkish and says 'No image available' Publish Video basically only send images when something changes or it gets a connection for the first time.

Yeah, I'm actually not surprised the extension doesn't fully work with completely static images. I cannot fully reproduce with a static image, but the following might be a clue:

How frequently does it happen? Also, are there any errors in GRIP.log in your home directory? I'm having trouble reproducing that regardless of how high quality the image is. Glad to hear it's working a little better. If the first works and the second doesn't, it's a bug in GRIP's 'Publish Video' step, and if the second works and the first doesn't it's a bug in the GRIP SmartDashboard It looks like the old message is gone but we now get 'No image available' or 'Connection reset' from time to time instead (although probably not as frequently as we were getting 'Invalid Stream'). using the USB webcam viewer to view a stream from GRIP (if you can run GRIP on the RIO).using the GRIP extension to view a regular CameraServer feed from the roboRIO.So, it can work with GRIP or CameraServer regardless of where the images are coming Try: GRIPExtension uses the FRC dashboard protocol and lets you customize the address.

WebcamViewerExtension uses the FRC dashboard protocol and is hardcoded to the roborio address, so it works when you're using CameraServer or GRIP on the roboRIO.

VideoStreamViewerExtension uses a standard M-JPEG stream and lets you specify an address, so it works directly with an IP camera.

That had no issues with the video stream from the Axis, so we don't think that's the issue. Originally we were viewing the camera's video stream using the VideoStreamViewerExtension widget. We are using a webcam (Axis 1011) and not a USB camera.
