Most webcam manufacturers do not provide drivers for Linux systems, including untu. Therefore, Linux developers must do their best to run the

Through the previous Linux UVCV4L2 Technology Brief Introduction (a) we understand the UVC and v4l2 simple knowledge.Here is a description of the USB device's documentation: http://www.usb.org/developers/docs/devclass_docs/So what do we need to do if we want to implement a UVC camera device?I simply looked at the kernel configuration file for several CM projects, and now the V4L2 drive configuration options

Through the previous Linux UVCV4L2 Technology Introduction (a) we have learned the simple knowledge of UVC and V4L2.So what do we need to do if we want to run a UVC camera device?I simply looked at the kernel configuration files for several CM projects and found that the V4L2 drive configuration options in those systems were open, but the Config_usb_video_config option was not open, That is, in the current

Ubuntu14.04 install GStreamer to test UVC H264 CameraRecently debugging UVC H264 Camera, need to test the camera in Ubuntu, so with the help of GStreamer to achieve.Gtreamer is a programming framework based on the glib library (the latest version needs glib2.0) to build streaming media applications, the goal of which is to simplify the development of audio/video applications that can now be used to deal wit

As far as I know, Linux will provide a unified drive framework for USB cameras in the future, that is, UVC. However, in fedora 14, no image is displayed after the camera is connected, but the system logs and hardware feedback are displayed as normal. After installing the guvcview graphical tool through yum, we found that there is a option called privacy, which is checked by default. after removal, the normal image is displayed immediately. At the same

I wrote two articles in front to illustrate the zc301 of the implementation of the specific see http://blog.csdn.net/hclydao/article/details/21235919The following by the way the general USB is also written on the front of the ZC301 get to the format is JPEG so do not have to do what processing can be used to display, but the standard UVC gets to the YUV422 format needs to be converted to RGB before it can be displayed here we in the previous two code

The so-called CMOS camera usually has a shit driver. If you want to apply the camera, you can use the UVC camera. This class shows the UVC camera's various parameter settings. It should be noted that if the frame rate is not high, it is often caused by the exposure time being too long. This relationship is like this. The longer the exposure, the better the image imaging quality, but the frame rate naturally

We believe that many people have used webcam. The use of webcam is not unfamiliar. In today's example, we introduce the snap design of webcam. If you've seen my Ubuntu core IoT design before, it's probably no stranger to the project. You can refer to my article "Snapcraft hands-on---Web Camera". Unfortunately, the webcam
