I have the issue that the image captured is cropped. I don't know where it comes from but I'm exploring all possibilities. Note that it works perfectly on a 32 bits os with same versions of v4l, kernel, libc and everything. The system is generated with Yocto so I'm 100% sure the versions don't change. I don't think the kernel plays a big role here and my knowledge about it is not significant enough to dig into the image capture calls easily. I tried using musl instead of libc but results are similar. I don't need to enable quirks to fetch the image when using it but the cropped image is exactly the same. Here is the system configuration: * Kernel 4.9.52 * v4l 1.14.2 * XHV57-NBL60 usb camera with uvcvideo driver Would you know how I could know V4l is not causing such issue?
