Picture, the only image of present frame in memory.
The present invention dynamically adjusts the broadcast strategy of sequence frame image, reaches money by the service condition of monitoring CPU and memory
Source allocation optimization has good effect.
In a specific embodiment, specifically include：
1, assume to need to play a height of 102,4*1,024 one wide and containing the gif file of 64 frame images
If 2, decoded gif file, image is all in deposit memories for playing, need to occupy at this time in save as：
Byte number * frame numbers=1024*1024*4*64=256MB that each pixels of Memory=wide * high * occupy
256 Mbytes of memories will be occupied.The memory of this size for mobile device very, may result in using because
It is collapsed for EMS memory occupation is full.
There are three types of the play mode of sequence frame image in this programme：
Pattern 1:CPU play mode decodes each frame image by CPU real-time circulations, there was only present frame in memory
Image.This pattern will generate CPU certain consumption；
Pattern 2:Memorymodel, i.e., will all be added memory after sequence frame image decoding, when broadcasting will no longer generate CPU solutions
Code consumption, can effectively reduce the consumption of CPU and electricity.
For this programme by monitoring the service condition of CPU and memory, the load mode of dynamic control sequence frame image reaches money
The optimization in source is handled.
1) service condition of system CPU and memory can be monitored by the method that system provides, monitors CPU and occupies
Rate CPU_Used and device memory free time size Free_Memory.
2) 2 threshold value CPU_Threshold=80% are set and indicate that CPU occupies as 80%, Memory_Threshold=
50 indicate equipment free memory free time 50, unit MB.
3) before loadingsequence frame image, formula can be passed through：The word that each pixels of GIF_Memory=wide * high * occupy
Joint number * frame numbers, which calculates this image and all loads into memory, needs the memory headroom size occupied.
4) compare GIF_Memory and Free_Memory：
If a, GIF_Memory>Free_Memory-Memory_Threshold then illustrates that remaining memory cannot
The whole loads for meeting this sequence frame image, can only play this sequence frame image by the way of CPU real-time decodings.
If b, GIF_Memory<Free_Memory-Memory_Threshold then illustrates that remaining memory meets this
Whole loads of sequence frame image, using memory load mode, reduce the consumption of CPU.
5) after no matter sequence frame image starts broadcasting in which way, in the monitoring readjustment of CPU and memory, do following
It calculates：
A, work as Free_Memory<Memory_Threshold and CPU_Used<When CPU_Threshold, i.e. free memory
When the threshold value and CPU set less than us occupies not up to threshold value, EMS memory occupation is higher at this time, needs to account for sequence frame image
Memory carries out discharging while being switched to CPU play mode.
B, work as Free_Memory>Memory_Threshold and CPU_Used>When CPU_Threshold, i.e. free memory
When the threshold value and CPU set more than us occupies over threshold value, CPU is occupied higher at this time, is needed to be switched to memorymodel, be subtracted
The consumption of few CPU.But operation 4) is first carried out before handover, sees whether meet switching condition
C, work as Free_Memory<Memory_Threshold and CPU_Used>When CPU_Threshold, i.e. free memory
When the threshold value and CPU set less than us occupies over threshold value, CPU and memory all occupy higher at this time, will be switched to CPU and broadcast
Mode playback, because memory, which is held over, will likely can lead to program crashing.
