Win10 Anniversary Upgrade Video Coding Problems Cause USB Camera to Malfunction

  
        

Beijing time on the morning of August 20th, Microsoft said that it is solving the video coding problem in the Windows 10 anniversary upgrade. This problem has prevented many users from using the USB camera and the corresponding application.

Many users report that their cameras and software are not working properly after installing the Windows 10 Anniversary Upgrade.

Windows camera team engineer Mike · Mike Morante said the problem is due to Windows 10's way of adjusting the video stream of the USB camera. Windows 10 no longer allows software to access video streams in compressed formats such as MJPEG and H.264, but instead requires software to use uncompressed YUV and NV12 formats.

If the program calls a video stream in MJPEG and H.264 format from a USB camera, the expected result will not be obtained.

Morant said that after this adjustment, if multiple applications running on the PC use a single camera at the same time, system performance will be optimized. In the past, three applications needed to call H.264 video streams three times from a USB camera, but now only one YUV and NV12 video stream is called.

However, since many applications have not been adjusted accordingly, some problems have arisen.

Morant said that Microsoft is developing separate solutions for MJPEG and H.264. The former solution will be released in September, and the latter has no clear timetable. (李丽)
