Fig. 2 is the structural representation of the system of the different Online Videos of dynamic load provided by the invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figure 1, the invention provides the method for the different Online Videos of a kind of dynamic load, comprise the following steps:
S1, Online Video comprises video main body file and the auxiliary fragment of video; Storage belongs to same video fileVideo main body file ID and the corresponding relation of video profile; Wherein, described video profile comprisesThe auxiliary fragment memory address of video and the auxiliary fragment ID of video. Wherein, the auxiliary fragment of video comprise video head,One or more in video run-out and video ads.
S2, before video main body file described in dynamic load, or, in video main body described in dynamic loadAmong the process of file, or, after video main body file described in dynamic load, described in needs loadingWhen the auxiliary fragment of video, resolve described video profile, obtain the auxiliary fragment ID of video; Then search slowDeposit, judge that in described buffer memory, whether storing the video corresponding with the auxiliary fragment ID of described video assists fragment,If judged result is no, carry out S3; If judged result is yes, carry out S4.
Concrete, video head described in dynamic load before video main body file described in dynamic load; MovingState loads after described video main body file video run-out described in dynamic load; Video master described in dynamic loadVideo ads described in dynamic load among the process of body file.
In practical application, especially for each video file that belongs to same video album, its common toolHaving identical video head, video run-out and video ads, is only video content difference. Therefore, for avoidingRe-cover video head, video run-out and video ads are loaded, in the present invention, load video firstWhen head, video run-out or video ads, be loaded in buffer memory, follow-up when calling same videoWhen head, video run-out or video ads, only need from buffer memory, directly call, and need to from hard disk, not weighNew loading, thus the video load time shortened.
In addition, in this step, after depositing auxiliary described video fragment in buffer memory, also comprise:
When the auxiliary fragment of described video, in described buffer memory, free time reaches predefined time span continuouslyTime, from described buffer memory, delete the auxiliary fragment of described video. By this kind of mode, can ensure to deposit in buffer memoryThe auxiliary fragment of the video being often called to that storage is active; For the auxiliary segment of not invoked video for a long time,From buffer memory, delete in time, thus the utilization rate of raising buffer memory.
S3, further resolves described video profile, obtains the auxiliary fragment memory address of described video, soObtain the auxiliary fragment of described video according to the auxiliary fragment memory address of described video afterwards, and described video is auxiliaryFragment deposits in buffer memory; Then carry out S4;
S4 reads described video auxiliary fragment, then video supplementary plate described in dynamic load from described buffer memorySection.
As shown in Figure 2, the present invention also provides the system of the different Online Videos of a kind of dynamic load, comprising:
Memory module, Online Video comprises video main body file and the auxiliary fragment of video; Described memory module is usedBelong to the video main body file ID of same video file and the corresponding relation of video profile in storage; Wherein,Described video profile comprises the auxiliary fragment memory address of video and the auxiliary fragment ID of video;
The first parsing module, before video main body file described in dynamic load, or, in dynamic load instituteState among the process of video main body file, or, after video main body file described in dynamic load, work as needWhile loading the auxiliary fragment of described video, described the first parsing module is used for resolving described video profile,Obtain the auxiliary fragment ID of video;
Search module, for searching buffer memory, judge in described buffer memory and whether store with described first and resolve mouldPiece is resolved the auxiliary fragment of video that the auxiliary fragment ID of the described video obtaining is corresponding;
The second parsing module, for when described in search module and do not find and described video at described buffer memoryWhen the auxiliary fragment of video corresponding to auxiliary fragment ID, further resolve described video profile, described in acquisitionVideo is assisted fragment memory address;
Acquisition module, for resolving the auxiliary fragments store of the described video obtaining according to described the second parsing moduleAddress, obtains the auxiliary fragment of described video;
Deposit module in, deposit buffer memory in for the auxiliary fragment of described video that described acquisition module is got;
Read module, for when described in search module and find and the auxiliary fragment of described video at described buffer memoryWhen the video that ID is corresponding is assisted fragment, or, when the described module that deposits in deposits described video in described buffer memoryWhen auxiliary fragment, read the auxiliary fragment of described video from described buffer memory, then described in dynamic load, video is auxiliaryHelp fragment.
The method and system of the different Online Videos of dynamic load provided by the invention, to each in video albumVideo file, is first loaded into the video head of identical content, video run-out or video ads in buffer memory,, only need to from buffer memory, directly adjust need to call these video head, video run-out or video ads time when follow-upWith, and do not need again to reload video head, video run-out or video ads, that is: do not need to re-coverLoad video head, video run-out or the video ads of identical content, thereby simplified video loading procedure,Improve video loading efficiency, finally improved video-see person's viewing experience.
The above is only the preferred embodiment of the present invention, it should be pointed out that common for the artTechnical staff, under the premise without departing from the principles of the invention, can also make some improvements and modifications,These improvements and modifications also should be looked protection scope of the present invention.
