Ethernet bandwidth limitations Oak-D

matthew

Hello, I am running a very basic pipeline that streams the left rectified, right rectified, and stereo depth images from the Oak-D PoE camera, and can't seem to get beyond around 600MBit/s bandwidth utilization. This limits the streams FPS to around 20Hz. Do you have any suggestions for getting over this low bandwidth limit? Or is moving to the video encoder the only option?

Thanks,
Matthew

Hello matthew, this could likely be the maximum bandwidth of our device. The link on the device itself is gigabit but can't be utilized (there's a lot of load on 1 core of the device). We still have some ideas on how to improve this (to around 700/800 MBit/s) but this isn't a critical feature so there's no ETA yet. As you mentioned, I would suggest using a video encoder if you plan to transfer large frames through ethernet.
Thanks, Erik
