In order to illustrate technical solution described herein, illustrated below by specific embodiment.
Fig. 1 is the implementation process schematic diagram of the seamless play method for the multimedia file that one embodiment of the application provides, such as
This method may comprise steps of shown in figure：
Multimedia file to be played is buffered in preset cushion space by step S101 when receiving preset instructions.
In the embodiment of the present application, the preset instructions can be the instruction that user's point opens webpage, can also be to more matchmakers
Body file carries out the instruction of loop play.As an example, when being loaded with multimedia file in some webpage, the net is pre-set
Page point opens the multimedia file of rear loop play webpage load, once user's point opens the webpage, mean that have received it is default
Instruction.In the embodiment of the present application, cushion space can be pre-set, multimedia file to be played can be buffered in preset
Cushion space, multimedia file, can be according to the broadcastings per frame data in multimedia file when preset cushion space stores
Order buffer is in buffer queue.Multimedia file can be audio file, can also be video file, can be by when storage
According to：First frame data of multimedia file to be played, the second frame data ..., the forms of last frame data stored.
Step S102 is played, and monitor institute after caching since preset cushion space obtains multimedia file
State the playing progress rate of multimedia file.
It in the embodiment of the present application, can be after multimedia file to be played caches, from preset cushion space
Data are obtained one by one to play out, and the playing progress rate for monitoring multimedia file is needed during broadcasting, it is described to broadcast
Degree of putting into is time point currently playing in the multimedia file playing process.
As an example, the data cached in the buffer queue of cushion space are：P1, P2, P3, P4 ..., Pn, caching
A total of n frame data of multimedia file after being cached to last frame data in buffer queue, can send a caching and terminate
Instruction, meanwhile, start decoding data plays out one by one from the beginning to the end from preset buffer queue：Obtain P1 simultaneously
It plays, obtain P2 and simultaneously play, obtain P3 and play, frame data broadcasting at once is not got when acquisition, but according to each
Reproduction time of the frame data in multimedia file plays out, it is assumed that the playing interval of every two frame data is T, in previous frame number
When according to T time after broadcasting, current frame data is played, the time due to obtaining the frame data from buffer queue is less than the frame number
According to reproduction time, obtained from buffer queue so each frame data can be realized as it is smooth, without Caton phenomenon.
Certainly, in practical applications, can also be arranged：After the frame data for having cached default frame number, from preset buffering
Space obtains data and plays out one by one.This is because in the process that acquisition data play out from buffer queue
In be to obtain and play since the first frame data, as long as before obtaining each frame data in sequence, which is buffered in
In buffer queue, when the data of front play out, data rearward can be carried out at the same time caching, in this way,
Shortening time that since webpage play being opened to multimedia file to a certain extent (or shortens and determines more matchmakers
Body file loop play to really start play time).
As an example, the cache-time per frame data is t1, and the playing interval per frame data is T, it is assumed that current cache N
Frame data can start to play, then, the data also uncached to n-th frame data are：N-N frames are cached to n-th frame data also
The time needed is：(n-N) * t1 are (n-1) * T from current first frame to the time that n-th frame data need is played to, as long as slow
Time (n-N) * t1 that n-th frame data also need to is stored to be less than or equal to from current first frame to being played to n-th frame data needs
Time be (n-1) * T, certainly, the value of n is the frame number for including in total to the multimedia file from 1.
In practical applications, the time t1 of one frame data of caching is likely less than the playing interval T of every frame data, in this way, only
Cache a frame data, so that it may play out to obtain a frame data from buffer queue.
Step S103 sets the playing progress rate when the playing progress rate is the end time of the multimedia file
It is set to the time started, the multimedia file is controlled and restarts to play.
In the embodiment of the present application, can be arranged multimedia file from first frame to last frame loop play, i.e., from
Head arrives tail loop play, when playing progress rate is the end time of multimedia file, sets playing progress rate to the time started, just
Broadcasting can be from the beginning re-started, can be specifically, after playing last frame data, continues to read the from preset cushion space
One frame data are decoded broadcasting.Since data to be played are maintained in cushion space, and it is every according to multimedia file
What the playing sequence of one frame data was stored, so, during loop play, can last frame broadcasting after, after
It is continuous to read the first frame data from cushion space and continue cycling through broadcasting, avoid interim card during loop play, incoherent existing
As realizing seamless play.
As an example, it is 0 at the beginning of the broadcasting of the multimedia file of setting:00, the end time 0:30, delay simultaneously
It is P1 to Pn to deposit the data cached in queue, can realize loop play according to the playing progress rate of present multimedia file, may be used also
To realize loop play according to the sequence of the data in currently playing buffer queue, with the playing progress rate of present multimedia file
For, if current playing progress rate is 0:30, then current playing progress rate is set as 0:00, control plays from the beginning, with
For the sequence of data in currently playing buffer queue, if the current data for obtaining and playing are Pn (last frame number
According to), then it from the beginning reacquires data P1 and plays, after P1 acquisitions data play out, continue according to the number in buffer queue
According to sequence obtain and play successively.In this way, no matter according to the playing progress rate of present multimedia file, according further to currently playing
Buffer queue in seamless play when may be implemented to switch during loop play of the sequences of data.
Fig. 2 is the flow diagram of the seamless play method for the multimedia file that the another embodiment of the application provides, and is such as schemed

It should be noted that for the browser of WebKit cores, need to add a webkit prefix, that is, create
WebkitAudioContext objects.
Step S202, after the instruction for receiving webpage unlatching, by decodeAudioData to the webpage
Multimedia file in audiocontext objects carries out asynchronous decoding.
In the embodiment of the present application, once receiving the instruction (for example, user opens the instruction of the webpage) of webpage unlatching,
Can by decodeAudioData to the multimedia file in the audiocontext objects of the webpage into line asynchronous solution
Code.
Web Audio API (Web Audio API support the audio file of multiple format, for example, common WAV,
The audios such as MP3, AAC, OGG) middle-size and small-size audio file is buffered using AudioBuffer methods, can specifically it pass through
XMLHttpRequest (var request=new XMLHttpRequest ()；XMLHttpRequest is expansible super text
This transmission is asked) method to ask audio file to be realized carries out.But it is non-textual since audio file is binary file,
It needs responseType=request.open (' GET', url, true)；Request.responseType='
arraybuffer'.Response type are Web api interface Response, including a kind of respond style, be read-only category
Property) be arranged to ' arraybuffer '.
Step S203 returns to the AudioBuffer examples for housing decoded multimedia file after decoding.
In the embodiment of the present application, after decodeAudioData () is decoded, this function can call a readjustment letter
Number is returned stores the audio after decompression comprising unpressed PCM format AudioBuffer examples.The decoded more matchmakers returned
Body document instance can be understood as the multimedia file of caching.
Step S202 to step S203 be actually how multimedia file to be played to be buffered in from bottom description it is pre-
If cushion space.
Step S204 is arranged at the beginning of the multimedia file plays and is more than with end time, the time started
Or it is equal to 0, the end time is less than or equal to the total time of the multimedia file.
In the embodiment of the present application, the time of audio broadcasting, function can be configured by function noteOn (time)
Total duration of the time of noteOn (time) no more than audio.For example, the time of audio long attribute duration is 5 minutes,
Could be provided as 3 minutes reproduction times, source.noteOn (180000), unit ms), the unisonances such as time are arranged in longest
The frequency time is long.We are by taking an audio file as an example, it is assumed that total playing duration of audio file is 5 minutes, we are arranged 3 minutes
Reproduction time, i.e., the time started be 0, the end time 3:00.In certain practical application, can also be arranged the time started is not
0, for example, it is also possible to be arranged from 1:00 starts to play, and is played to 4:00, the time started is greater than or is equal to 0, and the end time wants small
In or equal to the multimedia file total playing duration.
Step S205 is played, and monitor institute after caching since preset cushion space obtains multimedia file
State the playing progress rate of multimedia file.
