Picture, video metadata is mainly used in video file and video information is shown in terminal；Each different player plays video
Parameter required for file include starting the Starting mode of player with corresponding to each different player plays video file
Multiple identification codes.
The crawl of third party's aggregated application uses the aggregated metadata of the video file of different player plays, by video text
The aggregated metadata of part is sent to cloud server storage, when terminal receives the play instruction for indicating playing video file
When, the request of data of video file is sent to cloud server, when cloud server receives the request of data of the video file,
The aggregated metadata of the video file is sent to terminal.Terminal receives the polymerization member number for the video file that cloud server is returned
According to, and the request of user behavior statistics is sent to cloud server, cloud server receives user's statistics of terminal transmission
During request of data, the user behavior statistics that terminal in user's use is constantly uploaded is sent in terminal, terminal receives high in the clouds
The user behavior statistics that server is returned, and the determination broadcasting of default selection strategy is combined according to user behavior statistics
The first object player of video file.
Intelligence chooses statistical analysis of the selection strategy of first object player from cloud server to user behavior, system
The result of meter analysis includes the more player plays videos using which video provider of currently used user, and user
At most select the player plays of which video provider video file.Terminal according to default selection strategy priority from
High to Low to judge successively, when it is determined that meeting a selection strategy, the player that a selection strategy is indicated is defined as first
Destination player.
The priority of default selection strategy is followed successively by from high in the end：
The player that user is set is defined as first object player；
The player that cloud server is recommended for video file is defined as first object player；
Cloud server is analyzed to the most player of the playing video file number of times drawn and is defined as first object broadcasting
Device；
Cloud server is analyzed to the most player of the active user's access times drawn and is defined as first object broadcasting
Device.
Step 110：Terminal obtains first that correspondence first object player is set from the aggregated metadata of video file
Identification code, and by the first identification code start first object player, broadcasting be encapsulated in the aggregated metadata of video file with
Corresponding first video resource of first object player.
Specifically, after first object player is determined, terminal is obtained pair from the aggregated metadata of the video file
The first identification code for answering first object player to set, and obtain the Starting mode data of first object player, the first mesh
The Starting mode data for marking player come from cloud server, and any feasible Starting mode can all be supported, for example extensively
Broadcast mode, activity modes or intent modes, basic Starting mode data should include：The player to be started name
Title, the startup method of player and the identification code for starting the video file；Terminal is got first plays the video file
First object player, then starts first object player by the startup method of first object player, and by first
The incoming first object player of identification code, so as to start first object player, plays the video file and is encapsulated in video
The first video resource corresponding with first object player in the aggregated metadata of file.Video file correspondence first object is played
First video resource of device is provided with unique first identification code, and first identification code is sent to first object player, you can
Using the first video resource of first object player plays video file.
Wherein, as shown in fig.2, starting comprising the following steps that for first object the first video resource of player plays：Step
Rapid 200：The Starting mode data of first object player are obtained from the aggregated metadata of video file；Step 210：According to
The Starting mode data of one destination player determine the startup method and the first identification code of first object player；Step 220：
First object the first video resource of player plays is started by the startup method of first object player and the first identification code.
Step 120：When there is network condition change, terminal is selected and current net from the aggregated metadata of video file
Second video resource of network situation matching, will be used as the second destination player for the player for playing the second video resource.
Specifically, following the basic of the video resource that definition highest video file is played under conditions of network permission
Principle, when occurring network condition change in playing process, for example, occurring multiple interim card in playing process has influence on playing body
When testing, from the aggregated metadata of video file by calculate get the definition that is matched with current network conditions it is relatively low the

Rapid 330；
Step 320：Directly continued from the first video resource broadcasting finish time and play the second video resource；
Step 330：The slice header information for determining the first video resource is the first slice header information, and determines the second video resource
Slice header information be the second slice header information, and according to the first slice header information and the second slice header information calculating by first object player
Switch to the duration difference compensation produced during the second destination player；Finish time is played according to the first video resource poor with duration
Value complement repay positioning continue play the second video resource switching time point, and from switching time point continue broadcasting the second video money
Source.
For example, a length of 1 hour when first, a length of 04 minutes 1 hour when second, being provided by each video provider
The slice header information of video file, learns, the head that the first video resource is indicated in the first slice header information are 3 minutes, the second head
The head that the second video resource is indicated in information are 7 minutes, are calculated according to the first slice header information and the second slice header information by first
It is 4 minutes that destination player, which switches to the duration difference compensation produced during the second destination player, is broadcast according to the first video resource
Finish time is put, the switching time point for positioning the second video resource of broadcasting that continues for 4 minutes with the compensation of duration difference in such as 30 minutes should
Should be 34 minutes, and from switching time point continue within 34 minutes broadcasting the second video resource.
