2024年11月19日 · Hi, I have developed a driver for a camera that supports 3 modes, GREY, Y14, and Y16. The camera outputs in 1680x1050 @ 90,45, or 30. The issue is when I have use_sensor_mode_id = false and I use a command like v4l2-ctl -d /dev/video1 --set-fmt-video=width=1680,height=1050,pixelformat='Y14 ' --stream-mmap --stream-to=frame.bin it is …

2019年1月17日 · V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN 0x00000000 Unknown timestamp type. This type is used by drivers before Linux 3.9 and may be either monotonic (see below) or realtime (wall clock). Monotonic clock has been favoured in embedded systems whereas most of the drivers use the realtime clock.

2020年8月20日 · We want to get v4l2_buffer timestamp with system os. We use this follow method to update our code. But we found there are not match. How can we get v4l2 buffer timestamp with correct system os timestamp? (eptime us)1597886732.814339 (system os time)1597886725.256784 We still use JetPack3.3. Is there any way to get system os …

2022年10月3日 · When that failed I spent some time trying to cherry pick out the struct definitions (vb2_buffer, vb2_queue, vb2_plane, etc) but that quickly got down to some includes only available in the kernel source. I don’t think that using vb2_buffer (or vb2_v4l2_buffer) is …

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 …

2021年9月10日 · I’ve read reports that say that capturing video from a CSI-connected camera will only provide bayer data, and that only using libargus enables the ISP. I’d prefer to use v4l2, mostly because it has a C (vs C++) interface, which is easier to access via FFI. And, it does seem that when I use libv4l2, I get lots of libargus output. Before I go all the way down the road of …

2024年2月15日 · Hello All, I have customised the IMX219 driver and device tree for my custom sensor. I am able to get data through v4l2 but nvgstcapture is failing to work in jetson nano. I used the same customised driver in NX its working properly. I am attaching the argus log here. Let me know what could have been gone wrong. nvargus_log.txt (33.6 KB)

2016年12月15日 · I understand from the release notes (of L4T R24.2/R24.2.1) that the on-board CSI camera now supports v4l2 interface. But, I am not able to capture video from the camera using v4l2. Please provide a Gstreamer sample pipeline for the same.
