Cameras are very slow through MJPG web stream, but not on driverstation's dashboard #63

No idea why this would happen. @ArchdukeTim

@virtuald?

Lot's of people at competition were having issues with low FPS camera streams, even though the usage was only at ~2 MB/s

I don't understand the title.

On the driverstation's FRC Dashboard application (the top panel of the dashboard), the cameras run at a reasonable framerate. However, when the cameras are viewed through a browser stream (like at 10.14.18.2:1181/stream.mjpg, for instance), the framerate is 1-2fps. The same thing thus occurs when we try to show the camera streams through the mjpg stream on the dashboard. @virtuald

o rly... that's very curious. I don't have an explanation for this, you should post a question on CD and I'll point Peter at it.

Any idea what version of cscore you're using? It would be in the driver station logs if you have that available.

What resolution/fps are you specifying?

ErikBoesen commented 5 years ago

@virtuald We are specifying 160x120, however this problem occurs regardless of the resolution we use. We played around with the FPS to try and get a more consistent framerate on the driverstation dashboard, but this issue occurs regardless of what FPS we choose there.

I'm not sure what version of cscore we're using. I updated all our dependencies on the robot on Friday.
