The invention discloses a method and device for quickly displaying video. The method includes: extracting header file information of a video file, creating a storage space for storing the header file information in the video memory of a graphics card, and recording the storage space in the video memory. Location information, recording the mapping relationship between the identification of this video file and the storage location information of the header file information of this video file in the video memory; receiving the opening instruction for the target video file, according to the mapping relationship through the graphics processor of the graphics card according to the storage location information Load the header file information of the target video file from the corresponding storage space in the video memory, and after the loading is completed, read the video data of the target video file from the end position of the header file information in the target video file and play it through the display. In the present invention, the header file information is parsed by the graphic processor of the graphics card, which greatly shortens the time required for header file parsing and improves user experience.
Description
technical field [0001] The invention relates to the technical field of multimedia data processing, in particular to a method and device for quickly displaying video. Background technique [0002] With the continuous development of computer technology, the hardware configuration of the computer used for home or work is also continuously improved, which is mainly reflected in the development of its core device—Central Processing Unit (CPU). According to the word length and function of the microprocessor, the central processing unit has gone through the following development stages in turn: 4-bit and 8-bit low-end stage, 8-bit mid-range stage, 16-bit stage, 32-bit stage, Pentium series stage, Core series stage. With the continuous enhancement of the processing power of the central processing unit, the speed of computer processing tasks is also getting faster and faster, but even so, it still cannot meet the user's needs for certain operations in terms of user experience. For e...
