Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the disclosure provides a video monitoring method, which is applied to a cloud server, wherein a video management module, a monitoring virtual machine and at least one monitored virtual machine are arranged on the cloud server. As shown in fig. 1, the video monitoring method includes the following steps:
101, a video management module acquires video source file information in a monitored virtual machine corresponding to a monitored terminal and sends the video source file information in the monitored virtual machine corresponding to the monitored terminal to a monitoring virtual machine; the video source file information comprises a video source file and video information;
it can be understood that, in this step, the monitored virtual machine can process the video source file information normally, that is, the video played by the user at the monitoring terminal is not affected.
In an embodiment, as shown in fig. 2, the step of acquiring, by a video management module, 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 a monitoring virtual machine includes the following steps:
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 size of the display frame of the video player through the remote operation of the terminal device, such as a full screen display or a zoom display frame.
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 launched by microsoft on Windows Vista, and aims to provide a unified multimedia video solution for Windows platform, and developers can play video or sound files, transcode multimedia file formats, or encode a series of pictures into video, etc. through Media Foundation. Windows Media Player, etc. is written using the Media Foundation framework.
In an embodiment, as shown in fig. 3, the acquiring, by the video management module, video source file information in a monitored virtual machine corresponding to the monitored terminal, and sending the video source file information in the monitored virtual machine corresponding to the monitored terminal to the monitoring virtual machine includes:
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 size of the display frame of the video player through the remote operation of the terminal device, such as a full screen display or a zoom display frame.
Note that the second type in this embodiment refers to a case where DirectShow is applied.
FIG. 4 is a schematic diagram of the framework of DirectShow. As shown in FIG. 4, the framework of DirectShow consists of Filter, which is managed by Filter Graph Manager. DirectShow is located in the application layer. It uses a model called Filter Graph to manage the whole data flow process; each functional module participating in data processing is called a Filter; the filters are connected in a certain sequence in the Filter Graph to form a 'production line' to cooperatively work, and the work flow of the filters is shown in fig. 5. Filters are roughly classified into three categories according to their functions: source Filters, Transform Filters, and Renderingfilters.
Illustratively, taking an mp4 format as an example, the formats of video source files intercepted by DirectShow are two, one is an 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 bytes being the length of the NAL, not the start _ code. At this time, information such as profile, level, PPS, SPS, etc. of the encoder must be obtained by some global data to be decoded.
The video source file intercepted by the MediaFoundation is a standard H264 code stream, and one format is an annex-bbyte stream format, namely, the first 3-4 bytes of each frame are the start _ code of H264, and 0x00000001 or 0x 000001. Yet another difference is that MediaFoundation is to intercept the video stream directly in the source-file splitter, while DirectShow is to intercept the file stream in inputPin of TransformFilter.
It should be noted that DirectShow is a new generation development kit for streaming media processing based on com (component Object model) and developed by microsoft based on ActiveMovie and Video for Windows, and is released together with DirectX development kit. DirectShow uses a model called Filter Graph to manage the processing process of the whole data stream, and by using DirectShow, data can be conveniently captured from an acquisition card supporting a WDM driving model, and corresponding post-processing and even storage are carried out in a file. This facilitates access to multimedia data in a multimedia database management system (MDBMS). It widely supports various media formats including Asf, Mpeg, Avi, Dv, Mp3, Wave, etc., providing powerful support for the capture and playback of multimedia streams. Players such as storm audio and video, and entertainment are written by using a DirectShow framework.
