Description
Technical field
The present invention relates to cloud computing technology, particularly relate to a kind of method and system of play multimedia, server.
Background technology
Remote dummy interface, adopt the pattern of client-server, beyond the clouds, the server of i.e. remote data center fictionalizes the virtual interface that a set of user needs, and described virtual interface is shown in client, now, user uses described client and described virtual interface, and the operation interface just as using on main frame is the same; When the Internet is more and more popularized, described remote dummy interface tech can saving resource, can distribute hardware resource neatly again.
Under a lot of application scenarioss, such as: education, the scenes such as meeting, need that virtual interface is shared to a lot of user to use simultaneously, in such a scenario, be generally need the user of demonstration line correlation of being gone forward side by side by client access of virtual interface system corresponding to demonstration user operate by certain, be then pushed in other clients by the server that described virtual interface system is corresponding by described virtual interface, confession other users watch.
In existing scheme, usually presenting needing the direct mirror image of virtual interface shared to push in viewing client, being about to the Voice & Video be finally presented on virtual interface, being encoded into a stream of set form separately, and be sent to watch in client and present.Such scheme, for general demonstration operation, can meet consumers' demand, but for play multimedia information, particularly high-definition multimedia information, then can cause Consumer's Experience greatly to reduce because of the fluency deficiency of Voice & Video, its reason is, as shown in Figure 1, in existing virtual interface system 18, multimedia player 12 can first read pre-initial multimedia source 11 of playing, and will be presented on virtual interface corresponding to demonstrator 13 after the data decode of described initial multimedia source 11 correspondence, then in the encoder 14 of server 19 corresponding to virtual interface, the Voice & Video in the whole virtual interface in described initial multimedia source is had to be encoded into a stream again respectively broadcasting, be sent on each decoder module 16 of each viewing client 10 by respectively flowing through communication module 15, be presented on the virtual interface 17 of each client after each coding module 16 is decoded, so, all repeatedly to encode in virtual interface system and in server corresponding to described virtual interface system, described initial multimedia source of decoding, cause the fluency of the multimedia messages be finally presented on the virtual interface of client greatly to reduce, and, because the frame per second of media stream is higher, but the frame per second in virtual interface system is lower, to present multimedia messages corresponding to media stream more glibly, then need the frequency promoting media stream, thus can increase much unnecessary, repeat desktop images coding transmission process, so can increase the expense of server, and then cause the fluency of the multimedia messages be presented on the virtual interface of client to reduce, if do not promote the frequency of media stream, then the fluency being presented in the multimedia messages on the virtual interface of client then can decline greatly.
Summary of the invention
For solving the technical problem of existing existence, the embodiment of the present invention provides a kind of method and system, server of play multimedia, can overcome the excessive and slack problem of the multimedia messages being presented in client caused of server overhead.
For achieving the above object, technical scheme of the present invention is achieved in that
The invention provides a kind of method of play multimedia, be applied to server; Described method comprises:

Embodiment four
Fig. 7 is the schematic flow sheet of the specific implementation of the method for embodiment of the present invention play multimedia; Server pre-sets virtual interaction system; Fig. 8 is the concrete structural representation of the system of embodiment of the present invention play multimedia; As shown in Fig. 7, Fig. 8, in the remote dummy interactive interface that multichannel pushes, the concrete steps of the method for efficient play multimedia comprise:
Step 701: demonstrate client logs corresponding to user in virtual interaction system 81, and show virtual interacting interface 89 on demonstration subscription client 86;
Step 702: each viewing subscription client 87 is connected with server 80, and joins in multicast group corresponding to virtual interacting interface;
Here, the execution sequence of step 701 and step 702 can be exchanged.
Step 703: on demonstration subscription client 86, opens pre-initial multimedia source 82 of playing in multimedia player 83 by virtual interacting interface 89;
Step 704: described multimedia player 83 obtains the media stream of described initial multimedia source 82 correspondence;
Step 705: the media stream grabber 84 in the serviced device 80 of the media stream in described multimedia player 83 caught, described media stream grabber 84 reads the format information of described media stream, temporal information and positional information, and by after the encapsulation of the format information of data message corresponding for described media stream and media stream, temporal information and positional information, push on each viewing subscription client 87 corresponding to described multicast group by multicast mode;
Here, the format information of the data message that the described media stream after encapsulation is corresponding and media stream, temporal information and positional information are sent to each viewing subscription client 87 by the communication module 85 in described server 80;
Under the operating system of server is the condition of windows operating system, multimedia player generally adopts mediaFoundation framework to carry out multimedia, when each play multimedia, can create a mediasession object and a Topology object, mediasession object is used for controlling broadcasting; Topology object then comprises a series of interconnective player module, such as mediasource, stream, decoder etc., and each player module describes the data flow of whole playing flow, and allows to customize Topology object.In this case, described media stream grabber is exactly the Topology object of the specific customization under mediaFoundation framework, described media stream grabber can be loaded into by multimedia player, then when playing, by the communication module inside described media stream grabber direct forwarding data to server, data retransmission is gone out by described communication module.
Step 706: after each viewing subscription client 87 receives the format information of data message corresponding to the described media stream after encapsulation and media stream, temporal information and positional information, use the multiformat decoder 88 of self according to described format information, described media stream is decoded, subsequently, according to described temporal information and positional information, decoded described media stream is presented in the virtual interacting interface 89 of each viewing subscription client 87, for viewing user viewing.
Due to the media stream read in initial multimedia source, can be any form in theory, so the decoder employing a multi-format in client instead of the decoder of set form in prior art.Here, the CPU in client usually generally can be used to carry out soft solution to media stream, if but the permission of the hardware of client, then described client can use hard solution to accelerate decode procedure.
