in this step, the triggering condition is that the user opens the video player through the remote operation of the terminal device, or the user changes the display frame size of the video player through the remote operation of the terminal device, such as full-screen or zoom display frame.
Step 203, the video management module obtains video original parameters corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal in the video decoder according to the H264 code stream corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal;
step 204, the video management module obtains video playing parameters corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal in the video renderer according to the video original parameters corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal;

Note that the first type in this embodiment refers to a case applicable to Media Foundation.
Media Foundation is a new generation of multimedia application library that microsoft pushes on Windows Vista, in order to provide a unified multimedia audiovisual solution for Windows platform, and developers can play video or sound files through Media Foundation, transcode multimedia file formats, or encode a series of pictures into video, etc. Players such as Windows MEDIA PLAYER are written using the Media Foundation framework.
In one embodiment, as shown in fig. 3, the video management module obtains video source file information in a monitored virtual machine corresponding to a monitored terminal, and sending the video source file information in the monitored virtual machine corresponding to the monitored terminal to the monitored virtual machine includes:
Step 301, the video management module judges the type of the player;
Step 302, if the player is of the second type, the video management module acquires video original parameters corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal according to the video source file information in the monitored virtual machine corresponding to the monitored terminal, and separates the video source file corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal;
in this step, the triggering condition is that the user opens the video player through the remote operation of the terminal device, or the user changes the display frame size of the video player through the remote operation of the terminal device, such as full-screen or zoom display frame.
Step 303, the video management module obtains video playing parameters corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal in the video renderer according to the video original parameters corresponding to the video source file information in the monitored virtual machine corresponding to the monitored terminal;

The second type in this embodiment refers to a case applicable to DirectShow.
FIG. 4 is a schematic diagram of the DirectShow framework. As shown in FIG. 4, the framework of DirectShow is composed of filters, managed by FILTER GRAPH MANAGER. Directshowis located in the application layer. It uses a model called FILTER GRAPH to manage the overall data flow process; each functional module participating in data processing is called a Filter; the filters are connected in FILTER GRAPH in a certain order to form a "pipeline" to work together, and the working flow is shown in fig. 5. Filters are broadly divided into three categories by function: source Filters, transform Filters, and RENDERING FILTERS.
Illustratively, taking mp4 format as an example, there are two formats of the video source file intercepted by DirectShow, one is the avc1 format, without start_code, and the first 3-4 bytes are the size of the whole frame; the other is the original NAL packetization format, the first few bytes are the length of the NAL, not the start_code. At this time, information such as profile, level, PPS, SPS and the like of the encoder must be obtained by some global data so as to be able to decode.
MediaFoundation the video source file intercepted is a standard H264 code stream, one is annex-b byte stream format format, namely the first 3-4 bytes of each frame are the start_code of H264, 0x00000001 or 0x000001. Yet another difference is that MediaFoundation intercepts the video stream directly in the source file splitter, while directshowis intercepts the file stream in inputPin of TransformFilter.
Note that DirectShow is a new generation of development package for streaming media processing based on COM (Component Object Model), which is proposed by microsoft corporation on the basis of ActiveMovie and Video for Windows, and is published together with DirectX development package. DirectShow uses a model called FILTER GRAPH to manage the whole data flow, and by using DirectShow, we can conveniently capture data from the acquisition card supporting the WDM driving model, and perform corresponding post-processing and even store the data in a file. This facilitates access to multimedia data in a multimedia database management system (MDBMS). It supports a wide variety of media formats, including Asf, mpeg, avi, dv, mp, wave, etc., providing powerful support for capturing and playback of multimedia streams. The players such as storm video and audio and Aiqi are written by using a DirectShow framework.
