Good night (of the day, in the morning)!
I have a Logitech HD Pro Webcam C920. After the last update (2705), an opportunity to record in HD mp4, but now there is no ability to record uncompressed stream, it is impossible to record in a resolution of 1920 * 1080 * 30, the stop button does not work, video recording is performed and uses about 320-350MB ram. When you select a resolution 2304 * 1536 program refuses to work with the camera: writes that the device HD Pro Webcam C920 is not found, it is impossible to take a photo, only helps edit permissions in the registry by hand, which would return the program to a usable state. The site official the manufacturer indicates that the device has a resolution of 3Mp.
