If the frame per second of step 103, the first decoder decoding is less than the default play frame rate, preloads second and solve
Code device.Second decoder need to support the form of foregoing multimedia file.
Before step 103, include the step 100 of the default play frame rate of acquisition multimedia file to be decoded,
The sequencing of step 100 and step 101 and step 102 is not limited.
For example, the frame per second of the default broadcasting of multimedia file to be played is 30 frames/second, if the first decoder is decoded
Frame per second be less than 30 frames/second, then preload the second decoder.As the first decoder can be using the default play frame rate
The no preliminary judgement standard for being switched to the second decoder, the second decoder is then preloaded less than the default play frame rate.
Preload the second decoder to be beneficial in that, those skilled in the art can set further judgement mark
Standard, to decide whether the first decoder switching to the second decoder.If also meeting the further criterion, cut
Shift to the second decoder.Because the second decoder has been preloaded, therefore the decoding of multimedia file will not be interrupted, and improve decoding effect
Rate.Alternatively, if not meeting the further criterion, cancel and preload the second decoder.
The embodiment three shown in embodiment two and Fig. 3 shown in Fig. 2 provides two kinds of further criterion.
The method for the multimedia decoding that embodiment two is provided adds step compared to embodiment one after step 103
104：The frame per second that first decoder described in timing is decoded is less than the default play frame rate duration, if the time
More than the very first time threshold value of setting, then switch to the second decoder and decode the multimedia file.Alternatively, as do not met
Condition is stated, then cancels preloading the second decoder.
For example, very first time threshold value is 30 seconds, the example in embodiment one is continued to use, if the frame per second of the first decoder decoding
Less than 30 frames/second, and the state is continued above 30 seconds, then switches to the decoding of the second decoder, otherwise cancels preloading second
Decoder.
The method for the multimedia decoding that embodiment three is provided adds step compared to embodiment one after step 103
105：From the frame per second that the first decoder is decoded is less than the default play frame rate, if the picture for decoding predetermined frame number is disappeared
The time of consumption is more than the second time threshold of setting, then switches to the second decoder and decode the multimedia file；Otherwise, it is optional
Ground, cancels and preloads the second decoder.Second time threshold could be arranged to the predetermined frame number divided by the default broadcasting
Business obtained by frame per second, it can also be provided that the numerical value smaller than the business, is not limited herein.
For example, the frame of predetermined frame number 600, second time threshold is 20 seconds, the example in embodiment one is continued to use, from
The frame per second of first decoder decoding is less than 30 frames/from the second, if the time of decoding 600 frame pictures consumption is more than 20 seconds, switches
To the decoding of the second decoder, otherwise cancel and preload the second decoder.
The numeral listed in previous embodiment is only exemplary, it is therefore intended that convenient explanation, is not to present invention implementation
The restriction of mode.Those skilled in the art can make different settings according to actual conditions.

The optimal decoder of performance is used as the first decoder；The decoding performance averagely solves bit rate, minimum solution bit rate and highest solution
One or more of combinations in bit rate；The same type refers to same format and equal resolution and identical default
Play frame rate.
Those skilled in the art can decode the performance of the multimedia file of same type, and then selectivity with self-defining
Optimal decoder the first decoder the most of energy.
In a specific example, it is described selection the first decoder the step of include：Each decoder is counted to identical
The decoding number of times of the multimedia file of type, and the frame per second of its decoding are lasting less than the state of the default play frame rate
Time is more than the number of times of the very first time threshold value of setting, calculates the multimedia file that the number of times decodes type same as before with it
The ratio of number of times, then the minimum decoder of ratio is the optimal decoder of performance, selects the minimum decoder of the ratio to be used as the
One decoder.
In a specific example, it is described selection the first decoder the step of include：Each decoder is counted to identical
The decoding number of times of the multimedia file of type, and its decoding frame per second be less than the default play frame rate after decode predetermined frame
The time that several pictures is consumed is more than the number of times of the second time threshold of setting, calculates the number of times and decodes class same as before with it
The ratio of the number of times of the multimedia file of type, then the minimum decoder of ratio is the optimal decoder of performance, selects the ratio most
Low decoder is used as the first decoder；The same type refers to same format and equal resolution and identical default
Play frame rate.
For example, before this decoding, the multimedia file of the correspondence same type, the first decoder was called 10
It is secondary, wherein the frame per second for occurring for 5 times decoding is sustained for longer than the first of setting less than the state of the default play frame rate
The situation of time threshold, the second decoder was called 5 times, wherein the frame per second for occurring for 4 times decoding is less than the default broadcasting
The state of frame per second is sustained for longer than the situation of the very first time threshold value of setting, then in the first decoder and the second decoder,
The first decoder of preferential loading.
In another example, before this decoding, the multimedia file of the correspondence same type, the first decoder was called 10
It is secondary, risen wherein occurring the frame per second that decodes for 5 times less than the default play frame rate, decode that the picture of predetermined frame number consumed when
Between be more than setting the second time threshold situation, the second decoder was called 5 times, wherein 4 frame per second for occurring decoding are small
In the default play frame rate, the second time threshold that time that the picture of predetermined frame number consumed is more than setting is decoded
Situation, then in the first decoder and the second decoder, the first decoder of preferential loading.
The foregoing method preferred to the first decoder is beneficial in that for different multimedia files, dynamic monitoring
The efficiency of decoder decoding, and dynamic optimization is carried out to the loading sequencing of decoder.
Above-described embodiment is illustrated by taking two kinds of decoders as an example, and actual decoder is not limited to two kinds.
If all occurring in that situation about need to be switched when being available for all decoders called to decode same multimedia file,
Alternatively, the first decoder for being eventually switched to select before this decodes this document, and keeps decoding this document using the decoder,
Hereafter no matter there is the situation that the decoder of how many times first need to be switched by other decoders, the number of times is not counted in foregoing decoding
The calculating of energy.Those skilled in the art can also make different set.For example, in aforementioned schemes, being eventually switched to what is selected before this
After the decoding of first decoder, there is situation about need to be switched again in such as the first decoder, then according to priority before, switching
To other decoders, this time switching is included in the calculating of foregoing decoding performance.
