Hi,
Sorry for the late reply.
From your experiment, the issue may come from the camera → CUDA.
Do you use GStreamer for reading FLIR camera?
If yes, could you change the sample to read the video input via GStreamer?
This experiment can narrow down the issue is from FLIR camera or memory driver.
Thanks.
I’m using the FlyCapture library from FLIR to grab images but I don’t have access to the source code of the library. On the other side, I’m not aware of any way to grab images from FLIR camera using GStreamer. Is there any hypothesis that can be emitted on the memory driver ? Can I test such hypothesis ?
Hi,
We need to check the camera path first. Different route handles with a different driver.
Generally, CSI camera passes the nvcamerasrc component via GStreamer while web-camera use the v4l2src element.
Could you help us check which element the FLIR camera apply?
I’m not using GStreamer to capture the camera and I’m not aware of any way to do so. So I’m basically stuck with the library from the manufacturer.
Hi,
Another possibility may use the v4l2 interface to read the camera information into device DMA duffer.
Hi,
I’m out of the lab for the week. I will look into that at my return on oct. 2nd.
Hi francois,
It might be a long shot, but you FLIR USB camera might have some UVC driver compability. When you connect the camera, do you see something like this when running dmesg on the cmdline:
[12633.107599] uvcvideo: Found UVC 1.10 device LI-10635 (2a0b:00ea)
[12633.109205] input: LI-10635 as /devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2.2/1-2.2:1.0/input/input23
dmesg gives this output after plugin the camera:

The camera is apparently not UVC compatible. I can see a /dev/video0 in my tree but can not grab from it with gstreamer.
This thread does not seem to have found a solution to directly grab the camera with gstreamer either:
From that dmesg you should be able to see the camera with “lsusb -d 1e10:3300”. If you look at a verbose listing of this it will tell you which parts are of a standard class and which parts require a custom driver:
lsusb -d 1e10:3300 -vvv

Can a USB3 vision device be used as a source in GStreamer ?
I see miscellaneous and bulk classes, so this is not a generic video device and probably requires some form of software to adapt it for use in video (you won’t automatically get a “/dev/video#” when this is connected to USB unless there is other software to act as a kind of “glue” to video). Is there any kind of downloadable software or requirements information with that camera?
UVC will transfer in isochronous mode (continuous real time), this camera transfers in bulk mode (like a hard drive dumping one picture at a time), plus control interface (the miscellaneous).
Hi francois.miralles,
Is there any update on this issue?
Thanks.
