The content of embodiment with reference to corresponding to Fig. 1, Fig. 2 are a kind of broadcastings of the animation provided according to an exemplary embodiment
The flow chart of frame frequency method of adjustment.As shown in Fig. 2 method flow provided in an embodiment of the present invention includes：
201st, the number of image frames in duration is being specified according to animation, is obtaining the currently playing frame frequency of animation, animation is SWF texts
Part form.
The number of image frames refers to the amount of images that animation within a specified time plays.Animation is SWF file format, and it can be with
Including Flash animations, the video of SWF file format, SWF file format film etc..
In order to determine the relation between the currently playing frame frequency of animation and its broadcasting frame frequency set, it is necessary to be existed according to animation
The number of image frames in duration is specified, obtains the currently playing frame frequency of animation., in embodiments of the present invention, will for the ease of description
When playing the broadcasting frame frequency set for animation to be defined as specifying frame frequency, and frame frequency is played for cartoon setting, often according to marking in the industry
Standard realizes that the standard frame frequency for specifying frame frequency to be played for animation in the industry, it is 24 frames/second such as to specify frame frequency.
The embodiment of the present invention is not defined to the concrete numerical value for specifying duration, and it can be the total of the animation that this, which specifies duration,
Duration, i.e., from the time interval commenced play out when the animation to end plays the animation；It can also be animation that this, which specifies duration,
Played duration, one section of duration as in animation playing process, for example, a length of from the animation is commenced play out to broadcasting when specifying
Time interval during the half number of image frames of the animation.
When specifying during a length of different numerical value, number of image frames is also different numerical value.For example, a length of when specified, this is dynamic
During the total duration of picture, number of image frames is the image totalframes that the animation includes；When specifying during the played duration of a length of animation,
Number of image frames is played number of image frames corresponding to the played duration.
Further, when a length of different numerical value, number of image frames are also different numerical value when specified, specified according to animation
Number of image frames in duration, when obtaining the currently playing frame frequency of animation, including but not limited to realized by the following two kinds mode：
First way：When specifying, the total duration of a length of animation, number of image frames are the image totalframes that the animation includes
When, can be according to the total duration and image totalframes of animation, calculate animation first averagely plays frame frequency, and this first is averagely broadcast
Frame frequency is put as currently playing frame frequency.
For example, if total animation duration is 20s (second), the totalframes of the animation is 360 frames, then according to the total duration of animation
And image totalframes, the first average frame frequency of the animation being calculated is 18 frames/second.Now, determine that the current of the animation is broadcast
It is 18 frames/second to put frame frequency.
The second way：, can when when specifying, the played duration of a length of animation, number of image frames are played number of image frames
In animation playing process, to obtain the played duration of animation and played number of image frames, according to played duration and broadcast
Number of image frames is put, calculate animation second averagely plays frame frequency, second is averagely played frame frequency as currently playing frame frequency.
If for example, the animation got during animation plays it is played when a length of 10s, played frame frequency be
200 frames, then according to played duration and played number of image frames, it is 20 frames/second that second be calculated, which averagely plays frame frequency, this
When, the currently playing frame frequency for determining the animation is 20 frames/second.
Further, in animation playing process, when obtaining the played duration of animation and played number of image frames, may be used also
To choose played default value section playing duration, and count the played number of image frames in every section of playing duration.Now, exist
When calculating the second of animation and averagely playing frame frequency, played number of image frames that can first according to animation in every section of playing duration,
The average broadcasting frame number in every section of playing duration is calculated, and according to the average broadcasting frame number in default value section, it is flat to calculate second
Play frame frequency.
For example, choosing 3 sections of played playing durations, 3 sections of playing durations are respectively 5s, 8s and 10s, and this 3 sections are broadcast
It is respectively 90 frames, 160 frames and 190 frames to put the played number of image frames in duration, then this three sections average broadcasting being calculated
Frame frequency is 18 frames/second, 20 frames/second and 19 frames/second.Further, according to the average broadcasting frame number in this 3 sections, it is calculated
Second averagely broadcasting frame number is (18+20+19)/3=19 frames/second.
202nd, the mapping relations between CPU usage when playing frame frequency and playing animation are obtained.
Generally, during CPU usage difference when playing animation, animation can be played out with different broadcasting frame frequencies.Example
Such as, the CPU usage when playing animation than it is relatively low when, e.g., when CPU usage during playing animation is 10%, animation can
To specify frame frequency to play out, as animation can be played out with the broadcasting frame frequency of 24 frames/second；CPU when playing animation is used
When rate is bigger, when CPU usage during such as playing animation is 30%, the broadcasting frame frequency of animation, which is less than, specifies frame frequency, such as animation
It can be played out with the broadcasting frame frequency of 18 frames/second.That is, animation plays frame frequency and CPU usage during playing animation
Between have certain mapping relations.In order to determine CPU usage corresponding to currently playing frame frequency, can first obtain play frame frequency with
The mapping relations between CPU usage during playing animation, and subsequently determine playing animation when CPU when utilization rate when, root
Realized according to the mapping relations.
, it is necessary to pre-establish before the mapping relations between obtaining CPU usage when playing frame frequency and playing animation
The mapping relations between CPU usage when playing frame frequency and playing animation.Wherein, the broadcasting frame frequency pre-established is dynamic with playing
The mapping relations between CPU usage during picture, including but not limited to as shown in Table 1.Wherein, in Table 1, play frame frequency with
Utilization rate is one-to-one relationship during CPU during playing animation.
Table one
| Play frame frequency | Utilization rate during CPU during playing animation |
| 18 frames/second | 40% |
| 20 frames/second | 30% |
| …… | …… |
| 24 frames/second | 10% |
Certainly, the numeral in above-mentioned table one is only used for illustrating, and does not form the limitation to the embodiment of the present invention.
In addition, that establishes plays the mapping relations between frame frequency and CPU usage during playing animation, can also be such as table
Form shown in two：
Table two
| Play frame frequency | Utilization rate during CPU during playing animation |
| 16-18 frames/second | 40% |
| 19-21 frames/second | 30% |
| …… | …… |
| 21-24 frames/second | 10% |
Certainly, the numeral in above-mentioned table two is also only used for illustrating, and does not form the limitation to the embodiment of the present invention.In table two
In, between utilization rate it is many-to-one relation when playing frame frequency and CPU during playing animation, i.e., is a certain scope when playing frame frequency
When, correspond to a CPU usage during playing animation.
203rd, according to currently playing frame frequency, mapping relations are inquired about, will CPU usage conduct corresponding with currently playing frame frequency
First CPU usage.
The step is the specific implementation of the first CPU usage when determining playing animation according to currently playing frame frequency.
Specifically, after the mapping relations when having pre-established CPU when playing frame frequency and playing animation between utilization rate, it is determined that working as
Corresponding to preceding broadcasting frame frequency during the first CPU usage, it can be realized according to the mapping relations.For example, it can be somebody's turn to do by inquiry
Mapping relations, will CPU usage corresponding with currently playing frame frequency as the first CPU usage.
, can be by the broadcasting frame in currently playing frame frequency and mapping relations when inquiring about mapping relations in currently playing frame frequency
Frequency is compared one by one, using CPU usage corresponding to preceding broadcasting frame frequency in mapping relations as the first CPU usage.
Such as, if currently playing frame frequency is 18 frames/second, and when playing frame frequency and CPU during playing animation between utilization rate
Mapping relations as shown in Table 1, then can by currently playing 18 frames of frame frequency/second with it is each in the mapping relations shown in table one
Frame frequency is played to be compared, using corresponding to 18 frames in mapping relations/second during CPU during playing animation utilization rate 40% as first
CPU usage.
In another example if currently playing frame frequency is 18 frames/second, and utilization rate during CPU when playing frame frequency and playing animation
Between mapping relations as shown in Table 2, then by currently playing 18 frames of frame frequency/second with it is each in the mapping relations shown in table two
Play frame frequency to be compared, because 18 frames/second belongs to this frame frequency scope of 16-18 frames/second, therefore, by currently playing frame frequency 18
CPU usage 40% corresponding to frame/second during playing animation is used as the first CPU usage.
204th, when the first CPU usage is not less than the first predetermined threshold value, according to specified frame frequency, the rear continued broadcasting of animation is adjusted
Put frame frequency.
First predetermined threshold value be playing animation than it is smoother when CPU usage.For example, if playing animation is than smoother
When CPU usage be 10%, then first predetermined threshold value be 10%.
, can be by the first CPU usage and after determining the first CPU usage in the currently playing frame frequency according to animation
One predetermined threshold value is compared.When the first CPU usage is not less than the first predetermined threshold value, by the follow-up play for adjusting animation
CPU usage when frame frequency is to adjust playing animation.In addition, when the first CPU usage is more than the first predetermined threshold value, illustrate this
When animation be still able to play the follow-up play frame frequency that than smoother, now must need not temporarily adjust animation.
When being not less than the first predetermined threshold value in the first CPU usage, broadcast by the broadcasting frame frequency for adjusting animation to adjust
Put CPU usage during animation, it can be ensured that the broadcasting frame frequency for adjusting animation realized based on the first predetermined threshold value, from
And can avoid when the first CPU usage is less than the first predetermined threshold value, because blindness is made by adjusting the broadcasting frame frequency of animation
Into unnecessary operation.
Wherein, because when to specify frame frequency playing animation, animation can play must be than smoother, therefore, can basis
Frame frequency is specified, adjusts the follow-up play frame frequency of animation.Specifically, can be according to specified frame frequency, by the follow-up play frame frequency of animation
Adjust to the difference between specified frame frequency and be not less than the second predetermined threshold value.
On the concrete numerical value of the second predetermined threshold value, the embodiment of the present invention is not especially limited.It is however, in order that follow-up dynamic
Picture, which can play, to be adjusted follow-up play frame frequency to closer to better, therefore, this is second default with specified frame frequency than smoother
Threshold value is the smaller the better.
For example, if currently playing frame frequency is 18 frames/second, it is 24 frames/second to specify frame frequency, then adjusts currently playing frame frequency
Extremely with 24 frames/second closer to better.
In addition, on according to frame frequency is specified, adjusting the specific implementation of the follow-up play frame frequency of animation, including it is but unlimited
In each image included by optimizing animation.For example, change each image, render each image etc. again.
205th, determine with the second CPU usage during follow-up play frame frequency playing animation, when the second CPU usage is not less than
During the first predetermined threshold value, continue according to specifying frame frequency, the step of adjusting the follow-up play frame frequency of animation, until during playing animation
CPU usage is not less than the first predetermined threshold value.
The step is optional step.After the follow-up play frame frequency of animation is adjusted, in order to test with the follow-up play frame frequency
During playing animation, whether CPU usage during playing animation can be less than the first predetermined threshold value, it is thus necessary to determine that with follow-up play frame
The second CPU usage during frequency playing animation.
In a manner of determining the second CPU usage when follow-up play frame frequency playing animation, and continue according to finger
Framing frequency, adjusts the mode of the follow-up play frame frequency of animation, may refer to above-mentioned steps 201 to the content in step 204, herein
