| 发明名称 | Method and system for sharing a buffer between a graphics processing unit and a media encoder | ||
| 摘要 | A program module executing in a first process space of a mobile computing device receives a buffer request from a graphics driver running in a second process space of the mobile computing device, wherein the second process space is isolated from the first process space. The program module assigns a buffer to the graphics driver to store image data processed by a graphical processing unit (GPU) controlled by the graphics driver. The program module receives a release of the buffer from the graphics driver. The program module assigns the buffer to a media encoder driver for a hardware media encoder to encode the image data in the buffer into a file. | ||

| 主权项 | 1. A method comprising: receiving, by a program module executing in a first process space of a mobile computing device, a buffer request from a graphics driver running in a second process space of the mobile computing device, wherein the second process space is isolated from the first process space; assigning, by the program module, a buffer to the graphics driver to store image data processed by a graphical processing unit (GPU) controlled by the graphics driver; receiving, by the program module, a release of the buffer from the graphics driver; and assigning the buffer to a media encoder driver for a hardware media encoder to encode the image data in the buffer into a file. | ||
