Abstract

The invention discloses a streaming media mapping method under an RDP (Remote Desktop Protocol) environment, which comprises the following steps of server side development and client side development, wherein the service side development comprises the steps of developing a Transformer Filter, appointing receiving media file types and registering to a system; scanning the Transform Filter and loading by a Direct Show in the process of automatic connection, developing a Rending Filter and receiving corresponding instructions sent by player application programs, and transmitting the related data received in a server by a data transmission module to a client side; and a data receiving module for receiving a streaming media packet from the server, a Source Filter obtaining the steaming media packet from the data receiving module and backwards sending the packet to a data decoding module, and a local medial player program for loading the Source Filter to realize a complete Direct Show system and the play of the steaming media data on a local terminal are provided in the client side development. By the mode of data mapping, the data of the streaming media are transmitted to the terminal before decoding and is decoded and rendered by hardware resources of the terminal, thereby smoothly playing the media file.

Description

Streaming Media mapping method under the RDP environment

[technical field]

The invention belongs to the multimedia application field, specifically be meant Streaming Media mapping method under a kind of RDP environment.

[background technology]

Under the RDP environment user in the playing stream media file, the parsing of this media file and the work of playing up all concentrate on the server to be carried out on server.This using method has produced 2 problems:

1, because the video transmission mechanism of RDP has determined the refresh rate of RDP environment sub-screen can't reach the refresh rate that the normal play film needs, the slack phenomenon of picture appears when causing watching film under the RDP environment.

2, when the decoded stream media file, need take a large amount of server system resources, this has increased the weight of the server work load to a great extent.

[summary of the invention]

Technical problem to be solved by this invention is to provide Streaming Media mapping method under a kind of RDP environment.By the mode of data map, the data of Streaming Media are sent to before decoding on the terminal, utilize the hardware resource of terminal media file is decoded and to play up, reach the purpose of smooth playing media file.Keep the consistency of user on operating habit simultaneously.

The present invention solves the problems of the technologies described above by the following technical solutions:

The Streaming Media mapping method comprises the steps: under the RDP environment

Step 100: server end exploitation; Comprise the steps:

Step 101: exploitation Transform Filter, specify the media file type that receives, and be registered to system; DirectShow will scan Transform Filter and load in the process that is dynamically connected certainly;

Step 102: exploitation Rending Filter receives the corresponding command that player application is sent;

Step 103: data transmission module sends to the related data of receiving on the server on the client;

Step 200: client exploitation; Comprise the steps:

Step 201: data reception module receives the flow media data packet from server;

Step 202:Source Filter obtains flow media data packet from data reception module, and sends to the data decode module backward;

Step 203: local media player program, load SourceFilter, and realize a complete DirectShow system, realize the broadcast of stream medium data in terminal this locality.

Beneficial effect of the present invention is: 1, solve terminal slack problem during files in stream media on the Play Server under the RDP pattern; 2, solve the RDP server takies a large amount of server resources when the playing stream media file problem; 3, make full use of the hardware resource of terminal this locality, improve the effect of files in stream media under the RDP environment.

[description of drawings]

The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

Windows platform media player framework DirectShow be Microsoft for allow the programmer when the exploitation media player from the transfer of data of complexity, hardware differences frees in the work such as synchronism, and a cover media player framework of definition.

When the exploitation media file player application framework and bottom work are finished by DirectShow, like this, the multimedia application of developing based on the DirectShow framework will become simple relatively.On the windows platform, all basically media players are based on all that the DirectShow framework finishes.Fig. 1 is the DirectShow system schematic of a standard.

Filter is the minimum functional module in the DirectShow framework as the element in the DirectShow framework, and a Filter generally is made up of one or more Pin, and the connection between the Filter is finished by Pin.Filter is a kind of Com assembly, in order to allow the DirectShow system can load Filter, need register Filter in system before using Filter.

DirectShow will enumerate Filter all in the system automatically when the playing stream media file, and several Filter that will satisfy lowest term are linked in sequence, and forms a complete broadcast chain.Fig. 2 has simply explained the building process of a Filter chain.

Basic system according to the DirectShow system of above introduction can see that each media player comprises 3 Filter at least:

SourceFilter: be responsible for data organization, obtain data by local file system or the Internet;

TransformFilter: be responsible for data forwarding, and the media data decode operation;

RenderingFilter: media data output.

On this basis, can be by on server, replacing the purpose that Transform Filter reaches the Streaming Media mapping.

Concrete implementation detail comprises the steps:

Step 100: server end exploitation; Comprise the steps:

Step 200: client exploitation; Comprise the steps:

Fig. 3 is a Streaming Media mapping implementation structure chart.

The specific product operating process:

1, the TSX server program is installed on server;

2, in client the TSX client-side program is installed;

3, on server, watch film by RDP.

Beneficial effect of the present invention is: 1, solve terminal slack problem during files in stream media on the Play Server under the RDP pattern; 2, solve the RDP server takies a large amount of server resources when the playing stream media file problem; 3, take full advantage of the hardware resource of terminal this locality, improve the effect of files in stream media under the RDP environment.

Claims

1.RDP Streaming Media mapping method under the environment is characterized in that: comprise the steps:
