Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of picture frame player method.
With reference to the schematic flow sheet that Fig. 1, Fig. 1 are picture frame player method of the present invention preferred embodiment.
The present embodiment proposes a kind of picture frame player method, and described picture frame player method comprises:
Step S10, when receiving the playing request of video, according to the current frame rate of pixel value determination terminal of the size of memory space preset and the picture frame of current storage;
Step S20, judges whether described current frame rate is less than default basic frame rate;
Step S30, when described current frame rate is less than described basic frame rate, the picture frame corresponding based on described current frame rate creates Target Photo frame.
Step S40, plays the described picture frame of current storage and the Target Photo frame of establishment.
Particularly, in the present embodiment, comprise before described step S10 and store the step that high in the clouds sends picture frame, the step that described storage high in the clouds sends picture frame comprises: when receiving the picture frame that high in the clouds sends, the described picture frame received is stored into default memory, and when receiving the playing request of video, according to the size of the memory space preset and the current frame rate of the pixel value determination terminal of picture frame that prestores; Or described step S10 comprises: when receiving the playing request of video, receive the picture frame that high in the clouds sends simultaneously, and the described picture frame received is stored in preset memory, according to the size of the memory space preset and the current frame rate of the pixel value determination terminal of picture frame that prestores.Memory space in the present embodiment is preferably DDR memory (DoubleDataRate, Double Data Rate synchronous DRAM).It will be appreciated by persons skilled in the art that the DDR value that each TV is corresponding is different, as being designated DDR value corresponding to TV (X1) for 128MB, being designated DDR value corresponding to TV (X2) for 256MB.
In the present embodiment, with reference to Fig. 2, described step S10 comprises:
Step S11, when receiving the playing request of video, obtains the horizontal pixel value of the first frame picture frame in terminal current picture frame and vertical pixel value;
In the present embodiment, during terminal storage picture frame, preferred described picture frame is according to red pixel, the order arrangement of green pixel and blue pixel, the pixel value of the picture frame of terminal storage is equal, preferably when receiving the playing request of video, obtain the horizontal pixel value of the first frame picture frame of the current storage of terminal and vertical pixel value, the horizontal pixel value of described picture frame is the horizontal pixel sum of three kinds of pixels, vertical pixel value is the vertical pixel sum of three kinds of pixels, as the horizontal pixel of red pixel, when the horizontal pixel of green pixel and the horizontal pixel of blue pixel are all 2MB, the horizontal pixel value of described picture frame is then 6MB, in like manner, when described red pixel, green pixel, and the vertical pixel value of blue pixel is when being all 1MB, the vertical pixel value of described picture frame is then 3MB.
Step S12, is multiplied described horizontal pixel value with described vertical pixel value, to obtain the pixel value of described picture frame;
Step S13, by the storage capacity value of default memory space divided by described pixel value, to obtain described current frame rate.
In the present embodiment, for explaining detailed process in detail, be exemplified below: when terminal receives the picture frame of high in the clouds transmission, determine that horizontal pixel value and the vertical pixel value of the picture frame received are respectively 6MB and 3MB, DDR value terminal preset is if 128MB is as molecule, using the product 18MB of described horizontal pixel value 6MB and vertical pixel value 3MB as denominator, the current frame rate calculating terminal is 128MB/18MB=7.1, be understandable that, described dynamic frame per second is approximately 7, i.e. the picture of described terminal display per second is 7 frames.
Step S20, judges whether described current frame rate is less than default basic frame rate;
In the present embodiment, described basic frame rate is the frame per second of terminal demonstration animation effect, if terminal can the smooth frame per second showing animation effect be 20 frame pictures per second, from above-mentioned example, when described current frame rate be 7 frames per second time, described terminal can judge that current frame rate is less than default basic frame rate, is understandable that, described basic frame rate is preset as analog value according to specific needs.
