The calculation amount that one times can be reduced saves the decoding resource of half, promotes one times of decoding performance.
In one possible implementation, it is decoded, is obtained according to regional area of the coordinate range to present frame
The corresponding decoding data of present frame, comprising: all pixels in present frame in the coordinate range are decoded, and to present frame
In all pixels outside the coordinate range be filled processing, obtain the corresponding decoding data of present frame.
In one possible implementation, processing is filled to all pixels in present frame outside the coordinate range,
It include: to 0 filling of all pixels in present frame outside the coordinate range.For example, in present frame outside the coordinate range
All pixels are filled with 0x00000000.
