Player 2 sends playing request to media server 1；
Media server 1 sends broadcast address to download agent module 3；
3 downloads of media data of download agent module；
Download agent module 3 is debugged；
After the completion of debugging, corresponding media data is returned to player 2 by download agent module 3.
The present embodiment core scheme includes：
1, adapter tube player 2 downloads logic.The download policy of general player 2 itself determined by player 2, logic ratio
Relatively simple, if broadcast address is directly transmitted to player 2, play quality is unable to get guarantee, and download agent module 3 is used for
The downloading logic for substituting player 2, is directly changed to player 2 from the mode of 1 downloads of media data of media server by player 2
Data are read from download agent module 3, so that mounted mass under Optimal improvements, improves play quality.Specific practice is：It will be original
Broadcast address passes to download agent module 3, and download agent module 3 generates a new local broadcast address, by new sheet
Ground broadcast address passes to player 2.
2, download agent module 3 is connected.Normal condition adapter tube downloading only needs to pass to broadcast address into local downloading
Proxy module 3 can, but go wrong when need to debug, since the debugging difficulty of the equipment such as Android compares
Greatly, it is therefore desirable to connect the lesser equipment of the debugging difficulties such as PC.It at this time needs according to the configuration parameter of local file or straight
The mode for connecing preset parameter is connected to download agent module 3 in specified PC equipment, to facilitate with the download agent mould on PC
Block 3 substitutes local download agent module 3 and is debugged.
3, the broadcasting control informations such as broadcasting, pause, stopping, dragging in Android device are sent by being connected to the network
To the download agent module 3 on PC, the download agent module 3 for making the proxy module on PC substitute the local Android receives broadcasting
The control of device 2.It can choose using original ICP/IP protocol, the agreements such as HTTP can be used also to complete the biography of these information
It is defeated.
4, the download agent module 3 at the end PC creates downloading task, from matchmaker according to original broadcast address and broadcasting control information
1 downloading media data of body server return to corresponding media data then according to the media data request of player 2
Player 2 goes wrong if played, and directly repairs and debugs at the end PC, until the download agent problem reparation at the end PC, plays
Device 2 can normal play.
5, after being repaired the problem of the end PC, because the public a set of code of all platforms, can be replaced with the code after reparation
3 code of download agent module for changing the original problematic end Android, should also repair the problem of the end Android after replacement
?.
6, the connection control routine for modifying the end Android connects configuration from the download agent at the end PC and changes back Android
Local download agent module 3, verifying use the download agent module 3 of the local Android, if described the problem using normal
It is repaired.
The working principle of download agent module 3 introduced below：
3 essence of download agent module is by the downloading work substitution of 2 the inside of player.There are two major functions, and 1 is from matchmaker
1 downloads of media data of body server, 2 be to serve data to player 2.
1.1 from 1 downloads of media data of media server
Download agent module 3 supports the media data of two kinds of forms.One is the media data of single file, such as mp4,
The single files such as rmvb.64K once can be requested to media server 1 as unit of 64K to 1 request data of media server,
128K, 256K or 512K data.Then the data downloaded to are stored in inside memory, if the memory of setting is (in available
20% deposited) it writes completely, then new data are no longer downloaded, if there is new request of data, then can be chosen most inside available data
Old hash replaces.Data can be requested from the beginning of file, can also be from the intermediate request of file, can also be from text
The end of part starts to request.
Second is HLS protocol media.If only a kind of code rate, directly requests corresponding m3u8 to media server 1
File and corresponding ts file.If there is various code rate, the m3u8 file of all code rates can be first downloaded, lowest bit rate is then selected
Start to download.Then remove to download the ts file of corresponding code rate according to the request code rate of player 2.If the not number of request of player 2
According to just no longer being downloaded after downloading 5 ts files.
1.2 serve data to player 2
The webserver for starting a local to give player 2 offer service, and media data is passed through local
Webserver is supplied to player 2.It, can be out of proxy module after local webserver receives the request of data of player 2
Corresponding data are read in deposit data, are sent to player 2.For the media of HLS, it is also an option that the code rate sum provided,
For example media server 1 is there are three types of code rate, can choose and only provides one such or two kinds or three kinds, freedom degree compares
It is high.The user high for network speed, does not provide the media data of low bit- rate, promotes the clarity of user, the user low for network speed,
The media data of high code rate is not provided, user's Caton is avoided, avoids playing not smooth.
Original broadcast address and new local broadcast address are carried out corresponding method by download agent module 3 introduced below：
For the media of single file, we can calculate md5 value according to download address, and being then converted to length is 40
Hash value as download agent module 3 task mark, by corresponding task when player 2 requests media data to bottom
Hash value is transmitted to the webserver of download agent module 3, and the corresponding media data of hash value is returned to broadcasting by webserver
Device 2.
For the media of HLS, the parameter in download address is removed, the md5 value of download address is calculated, as media
Hash mark.When player 2 is requested, hash is used to collect m3u8 as parameter to proxy module webserver request one；Hash and
Code rate information passes to webserver simultaneously as two parameters, the expression as second level m3u8.M3u8 is added into code rate information
Calculate a new md5 value, the mark as ts file stream.
