?Here, according to the results of the reading document, according to the conditions of the UVC device, there is a fixed architecture on the hardware. So assuming that the hardware is not a UVC device architecture, it is very difficult to convert a normal camera into a UVC camera.Second, how can the Android system support the

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

There are many ways to achieve, according to the steps to see which kind of, online said what pick-up card, in fact, is to turn AV into UVC, now on the market a lot of cameras directly is already UVC, in Windows Plug and Play.Android is also Linux, this is a good run.1. First download the Android USB detection program, insert the UVC camera, in the program to see

Have done a bit of USB related things, recently because the project needs to learn a bit about multimedia knowledge. Then want to know about the UVC and v4l2 knowledge.First, two concepts are introduced:UVC:USB Video class(also known as USB Video device class or UVC) is a USB device class video product that does not require the installation of any driver to plug

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

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

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

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

I have collected a lot of information and learned a lot of useful things. Here I will record them to help others learn and use them later. // --------- The following is the content of the Microsoft website I have seen some questions about Windows Embedded ce DirectShow camera support.

/spca5xx) This series of drivers for the Sunplus chip camera, also applies to other chips, such as the current domestic cottage camera one brother "medium Star Micro" (Z-star) chip. Michel Xhaard, a defender of the project, started with a common driver around the age of 60 (about 2003), and was constantly modified to develop into a general-purpose driver that supports more than 250 cameras. He also wrote st
