Hello frankshieh , sorry about the delay. There's no 400P on Lite, but 480P (640x480) should go above 120FPS.

Thanks for this information - I'll look if the high fps could be the culprit herefrankshieh Thanks - will let you know how it goes.
Hello frankshieh,
the 10GB feature is still in development, should be out in main in 1/2 weeks
You can try it with the branch develop_embedded(depthai-python repo).Hello frankshieh , yes you can send frames from host to device with XLInkIN node. Simple code here - sending video frames to device for inferencing. For recroding/replaying, we are just refactoring this example but for now, you can use this demo.
Thanks, Erik- Edited
Hello @frankshieh ,
so the reason behind this issue is the XLink - protocol that we use between host/device. With the new version of depthai2.10.0.0, we have increased XLink packet size which will improve throughput by quite a bit - I am able to get 117.3 FPS running the code above. We haven't updated depthai_demo to 2.10.0.0 but will do today (you can do it yourself by changingdepthai==2.10.0.0inrequirements.txt)
Thanks, ErikAt the moment, the OV9282 sensor configs we use have limits as:
- 1280x800 and 1280x720: 60fps
- 640x400 (binning enabled): 120fps
We will need to replace the register configs in firmware, to be able to achieve higher FPS. Advertised from Omnivision:
But maybe higher is possible lowering the bit depth (from the current 10-bit to 8-bit), and we should also add custom sensor resolution config, to apply cropping (reducing number of lines, thus allowing for an even higher FPS).
