Abstract
The present invention provides a kind of method of asynchronous quick loading video thumbnails, including：Step 1, smart machine open the thread pool of the quantity of a loading video thumbnails task limited in the same time；Step 2, smart machine set up a memory management, and local file cache management；Step 3, when smart machine interface needs to show video thumbnails, will open a sub- thread and run inside thread pool；Step 4, sub-line journey generate the URL of the md5 value of 32 according to the address of video, go to search thumbnail by the URL, preserve the thumbnail；Video thumbnails are parsed and are shown by step 5, smart machine.The present invention can greatly improve, by obtaining data in internal memory or local file caching, the speed for loading video thumbnails.
Description
Technical field
The present invention relates to domestic intelligent apparatus field, the method for more particularly to asynchronous quick loading video thumbnails.
Background technology
The development of domestic intelligent equipment now and the contact of network more and more tightr, by numerous electricity by way of network
Sub- equipment is contacted together, and the technology interconnected between various equipment also reaches its maturity.As a kind of interconnection of smart machine also
Through starting the extensive family for entering domestic consumer, multimedia function is achieved by being connected with television set.Media are such as realized
Function, needs substantial amounts of video resource meet the demand of user, and user is in the Video Reservoir during Picking video resource, special
It is not that the video resource that oneself likes is selected, needs to understand the content of video in advance, needs to go to understand from other approach, for not
The video resource that is familiar with or knows nothing needs, and needs to play the video, carries out dragging broadcasting and goes to understand, for user
Speech, such experience is very original, generally screens suitable video resource and has just spent the substantial amounts of time.For such
Defect, existing way are by word brief introduction, allow user understand its content, but word brief introduction content is that comparison is thin, lead to
The mode to video interception is crossed, allows user faster more intuitively understand video content, how quickly to load video thumbnails is me
Need solve problem..
Content of the invention
For the problem that above-mentioned prior art is present, on the premise of interface fluency is not affected, rapidly load multiple
Video thumbnails show that, on interface, which includes technical scheme below：
The method of asynchronous quick loading video thumbnails, including：
Step 1, smart machine open the thread pool of the quantity of a loading video thumbnails task limited in the same time；
Step 2, smart machine set up a memory management, and local file cache management；
Step 3, when smart machine interface needs to show video thumbnails, will open a sub- thread and run inside thread pool；
Step 4, sub-line journey generate the URL of the md5 value of 32 according to the address of video, go to search breviary by the URL
Figure, preserves the thumbnail；
Video thumbnails are parsed and are shown by step 5, smart machine.
The thumbnail data with the presence or absence of the video in internal memory and local file caching is first looked for, if it does, that
The direct access data are parsed and are shown in interface.
In internal memory and local file caching, when thumbnail is not preserved, the video from the original of video, will be intercepted
Thumbnail, after intercepting, by the video thumbnails data, stores in internal memory and local file caching.
The present invention is had the advantages that compared with prior art：
The present invention can greatly improve, by obtaining data in internal memory or local file caching, the speed for loading video thumbnails
Degree.
Description of the drawings
Fig. 1 is the FB(flow block) of the modification method at the mobile terminal synchronously simulating smart machine interface of the present invention.
Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
As shown in figure 1, before this invention in specific embodiment, method includes：
S1, smart machine open the thread pool of the quantity of a loading video thumbnails task limited in the same time；
S2, smart machine set up a memory management, and local file cache management；
S3, when smart machine interface needs to show video thumbnails, will open a sub- thread and run inside thread pool；
S4, sub-line journey generate the URL of the md5 value of 32 according to the address of video, go to search thumbnail by the URL, protect
Deposit the thumbnail；
Video thumbnails are parsed and are shown by S5, smart machine.
Hereinafter above-mentioned steps are described in detail.
The smart machine of the present invention is a Household multimedia equipment for having intelligence system, except the system that installs is soft
Part, hardware components include CPU, memory etc..In the VIDEO PROJECTION technology of this present invention, also include for connecting with smart machine
Connect, and show the display device of smart machine content.First, a thread pool is opened on the backstage of smart machine, loading is regarded
The sub-line journey of frequency thumbnail is all placed in the thread pool and runs, and improves the opening speed of sub-line journey, limits sub-line in the same time
The quantity of Cheng Yunhang, it is to avoid because excessive thread causes smart machine operation slow.
While creating a memory management class on backstage, android system provides this class of LruCache, can limit
Spendable maximum memory value, and in the low memory of system, system can automatically reclaim the internal memory to ensure system
Fluency.
A local file cache management class is created, data is directly stored in the form of a file locally, and limits
Spendable maximum space.
When the interface of smart machine need to show video thumbnails, can backstage create a thread, by video address with
And need the control for showing to be delivered in thread, then the thread is added to inside thread pool, goes to manage the line by thread pool
The operation of journey.
When above-mentioned thread runs, first according to the address of video, a URL is generated according to the AES of MD5（URL
Can be understood as a mark）, it would be desirable to the interface control of display stamps this mark, completes it when video thumbnails are obtained
Afterwards, judge again, marking whether for the control is consistent with current, if unanimously just shown, if inconsistent, then will
Directly terminate this thread.Can so prevent, when multithreading is simultaneously using this control, cause thumbnail to show asking for mistake
Topic.
URL according to generating goes to retrieve with the presence or absence of the thumbnail data in internal memory, if it is present, directly from internal memory
Middle taking-up data are shown that at this time, the whole flow process that loads terminates, and speed of fetching data from internal memory is most fast.
If the not data in internal memory, then the URL according to generating goes to retrieve in local file caching with the presence or absence of should
Thumbnail data, if it is present, obtaining data from local file caching, the data is stored in internal memory, under being easy to
Data can be rapidly obtained from internal memory during secondary acquisition, then parse the data display in interface, at this time, whole loading
Flow process terminates.Speed is slightly slow compared to from internal memory.
If not getting data from internal memory and local cache, then will intercept directly according to original
Corresponding video thumbnails, intercept after completing, and the data are stored in internal memory and local file caching, for next time
When display, data can be quickly obtained in depositing from internal memory or this region and parse and show.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to the present invention's
Thought, all will change in specific embodiments and applications, and this specification content is should not be construed as to the present invention
Restriction.
