It is incorporated into specification and the accompanying drawing of a part for constitution instruction shows embodiments of the invention, and with
Description is used for the principle for explaining the present invention together.In the drawings, similar reference is used to represent similar key element.Under
Accompanying drawing in the description of face is some embodiments of the present invention, rather than whole embodiments.Come for those of ordinary skill in the art
Say, on the premise of not paying creative work, other accompanying drawings can be obtained according to these accompanying drawings.
Fig. 1 is the method flow diagram that video is quickly shown in the present invention.
Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.Need
Illustrate, in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined.
The basic thought of the present invention is stored in the header file information of video file at the figure of video memory and use video card
The header file information of device parsing video file is managed, compared to the side for parsing header file information by central processing unit in the prior art
Formula greatly shortens the time needed for header file parsing, makes user from certain video file is clicked on to seeing video file
Stand-by period between video image was foreshortened within 1 second, to improve the usage experience of user.
Fig. 1 is that quickly the method for display video, this method comprise the following steps in the present invention：
Step S101, it is determined that the N number of video file that need to quickly show, wherein N is the integer more than zero；To N number of video text
Each video file performs herein below in part：The header file information of video file is extracted, is existed according to the size of header file information
A memory space for being used to store this header file information is created in the video memory of video card, records the storage position of this memory space in video memory
Confidence ceases, and records reflecting for storage location information of the mark of this video file with the header file information of this video file in video memory
Penetrate relation.
Step S102, the OPEN for being directed to a target video file in above-mentioned N number of video file is received, is reflected according to above-mentioned
The relation of penetrating finds the storage location information of memory space of the header file information of target video file in video memory, passes through video card
Graphics processor according to the header file of above-mentioned storage location information respective stored space loaded targets video file from video card
Information, read the video of target video file after the completion of loading the end position of header file information since target video file
Data are simultaneously played by display.
Step S102 can be performed a plurality of times after the completion of performing in step S101 in this method, that is, completes the head text of N number of video file
After the storage of part information, one in this N number of video file can be carried out repeatedly to play or to more in this N number of video file
Individual video file plays out respectively.
When N value is more than 1 in this method, the video format of N number of video file can be same video format, or, N
The video format of individual video file is incomplete same.The video format of video file includes：Audio Video Interleaved (Audio
Video Interactive, abbreviation AVI) it is form, windows media video (Windows Media Video, abbreviation WMV), advanced
Stream format (Advanced Streaming Format, abbreviation ASF), dynamic image expert group (MPEG (Moving
Pictures Experts Group, abbreviation MPEG) form, RM forms, RMVB forms.
In this method, the set-up mode of memory space can use one kind in following two modes：
Mode one, the capacity and the memory capacity phase of this header file information of the memory space for storing a header file information
Together, the storage location information of memory space refers to the original position and end position of memory space.When performing step S101, lead to
The graphics processor of video card is crossed according to the head text of storage location information respective stored space loaded targets video file from video card
The method of part information includes：One memory space is determined according to the original position indicated in storage location information to end position, from
The header file information of this memory space loaded targets video file.
Mode two, for the capacity all same of N number of memory space for storing N number of header file information and empty for continuous storage
Between, the storage location information of memory space refer to the initial address of N number of memory space, single memory space capability value and deposit
Store up the identification number in space.This identification number is corresponding with the identification number of N number of video file, such as the identification number of first video file
For 0 when corresponding memory space identification number be also 0, corresponding memory space when the identification number of second video file is 1
Identification number is also 1.When performing step S102, by the graphics processor of video card according to storage location information from video card it is corresponding
The method of the header file information of memory space loaded targets video file includes：Calculate single depositing of being indicated in storage location information
The product of the capability value in space and the identification number of memory space is stored up, according to the first address and above-mentioned product indicated in storage location information
