Camera FPS on the nano

hey,

with the devkit and GStreamer, will it achieve in practice, encoding of 28 FPS at 3280x1848 ? (theory number of the nano)

and will a camera like that would work for that purpose :

thanks in advance.

Hi vbellet, the encoder supports up to 4Kp30 (3840x2160), so in theory it should keep up too at your resolution of 1848 vertical lines.

From what I can tell with the IMX219 sensors, their 4K resolution is for still images only.

Did someone with a nano and raspberry camera already tried at that resolution ?

3380*1848

I’ve tried before to capture 4K video from the IMX219 Raspberry Pi Camera Module v2 in 4K mode, but it does not seem to work, sorry. The product specs I’ve seen for that camera online imply 4K still images.

I see but one person on the forum did run that :

v4l2-ctl -d /dev/video0 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
	Index       : 0
	Type        : Video Capture
	Pixel Format: 'RG10'
	Name        : 10-bit Bayer RGRG/GBGB
		Size: Discrete 3280x2464
			Interval: Discrete 0.048s (21.000 fps)
		Size: Discrete 3280x1848
			Interval: Discrete 0.036s (28.000 fps)
		Size: Discrete 1920x1080
			Interval: Discrete 0.033s (30.000 fps)
		Size: Discrete 1280x720
			Interval: Discrete 0.017s (60.000 fps)
		Size: Discrete 1280x720
			Interval: Discrete 0.017s (60.000 fps)

To me that means it should work no?

That command just lists the formats - when I actually tried to run the capture @ 4K on that camera, it didn’t work for me.

Too bad :/

Here’s a new camera using IMX179 sensor that reports 4K @ 15FPS: http://www.appropho.com/products_ii_en.html?id=187&type=36#pdb04

great news. Unfortunately we are looking for a M12 or M8 lens :/ and we need to be have more 25 FPS at minimum resolution of 3280x1848 ( a bit less than 4k)

I think this one can do high FPS if the carrier board has a 4 lane connection: https://www.uctronics.com/index.php/arducam-8-mp-sony-imx219-camera-module-with-m12-lens-fisheye-for-invidia-jetson-nano.html

We tried this one and it also does not go above 120fps, even tho the spec says otherwise: https://www.uctronics.com/arducam-8-mp-sony-imx219-m12-mount-low-distortion-noir-camera-module-for-nvidia-jetson-nano.html

Any idea why? is it the kernel driver that thinks it’s a RPi V2 camera?

Hi razvan.grigore,
