Dear Aravis hello,
I want to set the frame rate using the arv_camera_set_frame_rate function.
The thing is when I set it to 150 frames and I read using the arv_camera_get_frame_rate function I get 66.49.
Does the maximum rate I could set is 66.49?
Thank you in advance
It depends on your camera, and how it is configured. Aravis by itself does not impose limits to the framerate.
arv_camera_get_frame_rate_bounds() will give you the device limits.
Hello Emmanuel,
Thank you for your answer, I called that arv_camera_get_frame_rate_bounds() function and this is the result.
the maximum bound is 66.493843 and the minimum bound is 0.499989
In the datasheet of my camera, I have this information:
Freerun mode frame rate 161
Trigger frame rate (continuous) 161
Trigger frame rate (maximum) 164
I am using the arv-tool-0.8 features to list all the features but, I have no device found in return.
This happens only with my USB camera even if I added the vendor to /etc/udev/rules.d/rules.
The maximum frame rate may depend on other settings, like the exposure time. That should be all explained in your camera documentation.
But as alwaysl, bug happens, it could be an Aravis issue.
Yes, I want to use the arv-viewer-0.8 to set manually the parameters.
my issue is when I run the arv-viwer-0.8 the USB camera is not listed in the list. I could only the ethernet camera.
I added the vendor to the /etc/udev/rules.d/rules but still couldn’t see the camera in the list.
Could you help, please?
Thank you in advance.
Could you run arv-viewer with debug enabled: arv-viewer-0.8 -d all, and post the console output here ?

mmm failed to open the USB device…
but it works if I use directly the library!
Trying running arv-tool-0.8 -d all as root and report the output here.
Hello,
I launched the arv-viewer-0.8 with a the root user and it works,
Thank you for your help,

Great.
This means the rules.d file is either wrong, or not taken into account. What is the content of your file ?

You probably need to tell udev to reload the rules:
udevadm control --reload-rules && udevadm trigger
And disconnect reconnect your USB camera.
