I am facing a very peculiar issue with my OAK-D Lite Luxonis camera.
I am running a YOLOv9 Medium model on my QT application on a camera stream from an OAK-D Lite.
The GPU is a GTX 1650 with 4GB VRAM. The general FPS I am getting on my model is around 25-30.
This works normally. But after a restart of the system the next day, the FPS on the camera stream goes down and fluctuates between 9FPS to 30FPS. And the fluctuation is visible on the camera in terms of frames also lagging and flickering. I have tried restart of the camera stream multiple times and yet it remains the same.
But when I physically remove the usb cable and attach it back and then start the stream, it resets somehow and gives the normal 25-30 FPS. The usb cable is a USB 3.0 cable and the UVC app works with the cable.
The system is a ubuntu 22.04 OS with 12 cores and 12 GB RAM on a B450M K motherboard with AMD Ryzen 5 2600 chip.
I get similar behaviour with the depthaidemo.py app also. I have attached screenshots, Sometimes after several restarts in the depthademo app it will reset and start giving 30FPS in the app. Same works for the camera stream on my app as well. But the number of restarts needed of the stream are random and not specific. A physical usb detach reattach almost always works and resets the FPS to 30 and then the camera works for the entire day properly without any issues until the next restart of the system the next da
