Raspberry HQ camera FPS

I try to run Raspberry Pi HQ camera IMX477 on Jetson Nano 2GB Developer Kit, with boost the NVCSI/VI clocks, 4056 X 3040.
Jetson have 1.5Gbps/lane * 2 lanes , it have to be ~20-24 fps, but I got ~10 fps only.

What problem is can be?

Did you run argus_camera --kpi?

5

What’s the version? J4.4/J4.5?

6

J4.5
argus_camera also shows ~10-11fps

8

We were verified on J4.4.1 get below result. However J4.5 looks like have problem on my platform.

$ argus_camera --kpi
PerfTracker 1: frameRate 30.02 frames per second at 1 Seconds
PerfTracker: display frame rate 30.50 frames per second
PerfTracker 1: framedrop current request 0, total 0
PerfTracker 1: latency 37 ms average, min 37 max 38
PerfTracker 1: frameRate 29.97 frames per second at 2 Seconds
PerfTracker: display frame rate 30.00 frames per second
PerfTracker 1: framedrop current request 0, total 0
PerfTracker 1: latency 37 ms average, min 37 max 37

Thank you. I will test J4.4.1 and let you know.

BTW, how is it possible to get 30FPS on 2 lane x 1.5 gbps?
4056 * 3040 * 10 * 30 = 3.6Gbps.
Maybe you test something wrong?

Below maybe relative topic.

resolved. 29.9fps.

@prapor How did you achieve 30fps with the Nano + IMX477? Was it a particular Jetpack version? How does the math work out? It doesn’t seem like it should be possible with the 1.5Gbps bandwidth per lane. Were you able to encode 30fps in both h264 and h265? Thanks!

Looks like it is indeed possible to capture the full 4:3 sensor resolution at 30fps in both h264 and h265. Not sure how it works out with the lane bandwidth, but it works.
