Abstract:
1. A driving method for a video device comprising: obtaining a first instruction of a first operating system from a virtual file system of the first operating system; converting the first instruction of the first operating system into a second instruction of a second operating system, wherein the first operating system is different from the second operating system; virtualizing a kernel of the second operating system; and controlling a video driver for the video device for the second operating system to drive the video device according to the second instruction of the second operating system through the virtualized kernel of the second operating system; setting up a virtual interface driver in the kernel of the second operating system, wherein the virtual interface driver drives a connecting interface through the video driver, and the video driver drives the video device through the connecting interface; registering the video driver to the virtual interface driver; and wherein the step of controlling the video driver comprises: transmitting a start instruction to the video driver through the virtual interface driver, such that the video driver drives the video device to start transmitting video stream.
