As shown in figure 1, a kind of player method of the composite video comprising SCVF single channel voice frequency multi-channel video, comprises the steps：
S1. composite video is opened；Comprising SCVF single channel voice frequency and multi-channel video in composite video.
S2. the SCVF single channel voice frequency and multi-channel video in composite video is recognized；Determine the quantity comprising video in composite video
Information, it is determined that main view corresponding with audio frequency frequency；The main view frequency refers to the video for providing audio frequency, i.e. sound-content in audio frequency is
Taken place frequently out by main view.With competitive sports as example, including audio frequency, the video of ewscaster and each visual angle of multichannel explained
The video of match scene, wherein, ewscaster explains to race, then video based on the video of ewscaster, the video of ewscaster
With the audio frequency of explanation by timestamp synchronous, other each road videos and ewscaster's audio video synchronization；
S3. the subwindow of respective amount is set up in broadcast window according to the quantity comprising video in composite video, and will be every
All the way video is corresponded with window；In being embodied as, when five road videos has been identified, in broadcast window five sons are set up
Window, and each subwindow plays video all the way；Subwindow carries out the tune of position, size, level as desired by pulling
It is whole.Often increase a subwindow, the consumption to system resource will increase, therefore, son is set up according to the quantity information of video
Window, rationally using system resource；
S4. read for the first time, front 100 frame and front 100 frame per video all the way of audio frequency is obtained, when audio frequency and Ge Lu are regarded
When frequency is discontented with 100 frame, all obtain；The frame number of acquisition is more, more to the occupancy of the system resources such as internal memory, therefore, protecting
Less frame number that obtains also embodies the reasonable utilization to system resource in the case of card composite video broadcasting smoothness.
S5. main view frequency is synchronous by timestamp with audio frequency, other videos are by frame number and main audio video synchronization.Particularly
Refer to the 1st frame of other road videos and the 1st frame synchronization of main view frequency, the 2nd frame of other road videos is same with the 2nd frame of main view frequency
Step ... ... the Y frames of other road videos and the Y frame synchronization of main view frequency.Multithreading audio frequency and video are carried out according to audio time stamp same
Step decoding, pinup picture, audio frequency are played and shown；When playing to 95 frame, operating procedure S6 while composite video is played；Start
More rearward, then the consumption to system resource is less for the frame number of operating procedure S6, but the frame number of startup optimization step S6 is leaned on very much
Afterwards, the broadcasting of composite video just occurs the phenomenon of interim card, therefore, during for choosing 100 frame audio frequency and each road video every time,
Preferred startup optimization step S6 when playing to any one frame in 90-95 frames, that is, reduce the consumption to system resource,
In turn ensure that the smooth playing of composite video.
S6. the X time reading, obtains the 100 frame audio frequency and each road video started from current frame number, if without data,
Then to step S7；If data, to step S5；X is the positive integer more than 1；
S7. when step S6 is obtained less than new played data, the content in S5 just terminates whole compound after finishing
The broadcasting of video.
The present invention plays the composite video file for including SCVF single channel voice frequency multi-channel video, by obtaining audio frequency number therein
According to, video data is synchronized according to the time of audio frequency, then using multithreading multi-channel video and audio frequency are solved simultaneously
Code, by the video data after multipath decoding the ad-hoc location i.e. subwindow of same broadcast window is mapped to, per road video correspondence
The position of subwindow carry out the adjustment of size, level by pulling, audio data decoder is played by sound card, it is final to realize
The synchronous broadcasting of composite video.
