2023年4月5日 · Hello there, We are trying to bring up the Cameras in our custom board with AGX Orin 32GB module and JetPack 5.0.2. The following is our current configuration: We are using 1 SG5-IMX490C-GMSL2-Hxxx SONY 5.44MP IMX490 RGGB x4 Camera(no ISP), plugged to Orin CSI port4 through the max9296 GMSL2 LINKA.

2020年8月27日 · You may need to account for the fixed point scaling used within the camera drivers. Look at v4l2-ctl -l to see the min, max, and step values for the exposure control. I think you will find that the units are not micro seconds.

2023年10月10日 · Hello, my goal is to A. use logitech 4k usb camera. B. capture 4k frames (to get 4k uncomressed representation in memory) C. save raw data to disk ( 4k, bmp, uncompressed) my work plan is : A. Done: set v4l2 to capture 4k (40962160,MJPG). B. Done: write & execute c++ app that uses v4l2 c. TODO: validate i have in-memory raw representation of the image (40962160 bytes) C. TODO: save raw data ...

2022年10月3日 · Hi, I have a Jetson Xavier NX, L4T version we are using is 32.5. We are using radar ‘iwr6843isk’ to capture raw data and pass it to Jetson. I would like to get time stamps from the driver we use for each frames. I went through some of the related topisc Also I have tried printing the time stamp for start and end of frame from the vi driver. But I want to get the exact timestamping from the ...

2021年2月11日 · I am comparing the output of the raw data captured through v4l2 on the Xavier NX and Nano platforms, and found an unexpected difference. I configure the camera to create a very bright image (to better see the data), and using the command v4l2-ctl --stream-mmap --stream-count=1 --stream-to=raw.dat I get the following output on the Nano (seen in a hex editor): FF 0F FF 0F … This is consistent ...

2018年9月7日 · Hi support, I have developed a pcie v4l2 driver support V4L2_MEMORY_MMAP feature,and can capture video from pcie (FPGA). I have disable pcie MMU and reserved specific address used by pcie in dts file.

I saw the following answer : V4l2 returning 14-bit raw instead ...

2020年6月22日 · hello czyhit, FYI, according to Camera Architecture Stack. you should access UYVY camera sensor via v4l2src; since libargus and nvarguscamerasrc working with bayer formats. seems you’re using V4L2 IOCTL to verify basic functionality during sensor bring-up, there’s failure for stream-on. please also check Verifying the V4L2 Sensor Driver session to have compliance test; you may also refer ...

2018年2月2日 · Hi All, I want to know that how to check v4l2_dbg message in the console. Target board is TX2 and source version is R28.1 I think that it will be control with console_loglevel. Is it right? Anyway, Please let me know for that detail. Thanks & BR,
