Issue Description

arake001 commented 5 years ago

I have an overflow of frames. Resolution of depth data falls by half from 1280x720 to 640x360 and fps is fluctuating from 21 to 30 fps.

I had this problem on Nvidia Jetson Xavier. The solution that worked for me was to use an external PCIe to USB3 card.

arake001 commented 5 years ago

@darrell-rg I am using USB3 card. But still, I have the same issue.

Could you check please if the overflow errors disappear if you use a lower resolution, please?

I have experiment this fluctuation in the fps on Windows, in Ubuntu it disappears. Other thing you could try is turning off the Auto Exposure Priority, this can be found on the RGB options under the controls section. Maybe it is also due to the auto exposure setting....
