The monitoring method of the multi-channel video provided by the embodiment of the invention can be suitable for monitoring the whole process of the network video signals of various video channels. For the convenience of understanding, the overall architecture diagram of the video stream overall flow process in the embodiment of the present invention is shown in fig. 2.
Referring to fig. 2, the present invention provides a full flow architecture for four different video signal sources, wherein the full flow architecture is roughly divided into four parts, namely receiving, scheduling, encoding, live video broadcasting or on-demand pulling.
The method comprises the steps that a video signal source receives a video signal from a satellite receiving side, the video signal is accessed to a scheduling layer through a Serial Digital Interface (SDI) or an Internet Protocol (IP) network interconnected among networks, the video signal is output by the scheduling layer and then enters a coding layer through the SDI or the IP network to be coded and then converted into an IP data stream, the output network video signal is finally entered into a live broadcast or on-demand layer through the IP network, and the IP data stream is converted, packaged, stored and pulled to be used by a live video broadcast or on-demand system on the live broadcast or on-demand layer.
Wherein 1) the receiving section. The reception of four different video signal sources is shown in fig. 2. 2) The scheduling layer uses different scheduling modes for different video signal sources to distribute, for example, for live video, a multicast network mode is generally adopted to implement. For another example, for video on demand, the received video signal may be scheduled by matrixing. 3) The coding layer may adopt different coding modes, such as hard packet broadcast coding, hard Time Messaging Protocol (RTMP) push stream, and the like. 4) And the live broadcast or on-demand layer is used for carrying out conversion packaging, storage and the like on the coded video signal for a live video broadcast or on-demand system.
In order to monitor the whole flow of a video channel of a multi-channel video and further improve the monitoring efficiency, the embodiment of the invention also provides other auxiliary monitoring methods, such as the monitoring link in fig. 2, and the method can also comprise the functions of link segment monitoring, equipment base monitoring, audio/video signal source detection, FLV stream monitoring analysis, stream slice detection and screenshot preview.
In order to solve the problem of low video monitoring efficiency in the prior art, in the embodiment of the present invention, a video stream of a plurality of video channels is subjected to screenshot, and a moving picture file corresponding to the plurality of captured video channels is displayed, so as to implement multi-screen monitoring on the plurality of video channels, based on the above-mentioned embodiment, referring to fig. 3, which is a flowchart of a monitoring method for multiple videos in the embodiment of the present invention, the method includes:
step 300: and the monitoring server acquires video streams of the current time period from the video channels of the multi-channel videos respectively.
Optionally, in the embodiment of the present invention, the video stream of the video channel of the multiple channels of videos may be acquired according to a preset period.
In the embodiment of the present invention, the monitoring server may communicate with a plurality of types of video servers, and the video servers may transmit video channels of multiple videos, such as video channel 1, video channel 2, video channel 3, and the like.
In practice, to reduce the volume of a video file, the video file is usually fragmented, and for different Streaming media protocols, there are different fragmentation manners and storage manners, for example, a dynamic bitrate adaptive technology (HTTP Live Streaming, HLS) protocol, and finally, a ts file (fragmented file) and an m3u8 file (index file) are stored on a video server, taking the HLS protocol as an example, when the monitoring server obtains a video stream from a corresponding video server, that is, when step 300 is executed, the method specifically includes:
first, the identification of the video channels of the multi-channel video and the download addresses of the video streams are obtained.
For example, the monitoring server may obtain the identification of each video channel and the download address of the video stream from the database.
In addition, in the embodiment of the invention, the video channel to be monitored can be selected in advance, and the identifier of the video channel selected in advance and the download address of the video stream can be further acquired.
And then, acquiring an index file of the video stream according to the download address of the video stream.
Optionally, in the embodiment of the present invention, the index file may be obtained according to a first preset period, for example, the index file is pulled every minute at regular time.
And finally, acquiring the fragment file of the video stream according to the index file of the video stream.
Specifically, the index file is an m3u8 file, and the m3u8 file records an index plain text file, obtains the index therein by parsing the m3u8 file, and can pull the corresponding ts file, i.e., the fragment file, according to the index.
Further, in the embodiment of the present invention, the fragmented file may also be stored. Preferably, the corresponding slice file is named and stored using the identification of the video channel.
Step 301: and the monitoring server detects the video stream of each current time period and judges whether a preset abnormal event is detected.
Taking the detection of the video stream of any one of the current time periods as an example, the step 301 can be divided into the following cases:
in the first case: and if the video stream of the next time period of the video channel corresponding to the video stream of any current time period is determined not to be acquired, determining that the cut-off abnormal event of the video stream of the corresponding video channel is detected.
Preferably, if the video stream is acquired periodically, it may be determined whether there is a situation in which the video stream is not acquired in two consecutive periods, and if so, it is determined that the cut-off abnormal event is detected.
In the second case: and if the audio data in the video stream of any current time period is determined not to be detected, determining that the mute abnormal event of the video stream of any current time period is detected.
In the third case: and if the pixel color values of the pictures of the continuous preset frames of the video stream at any current time interval are determined to represent black, determining that the black screen abnormal event of the video stream at any current time interval is detected.
In a fourth case: if the fact that the pictures of each frame of the video stream in any current time period are the same is determined to be detected, the fact that the static frame abnormal event of the video stream in any current time period is detected is determined.
Of course, by detecting the abnormal event of the video stream, other abnormal events, for example, an abnormal screen splash event, etc., may also be detected, and the embodiment of the present invention is not limited.
Step 302: and if the monitoring server determines that the preset abnormal event is detected, sending an alarm instruction to the monitoring terminal so that the monitoring terminal gives an alarm.
Specifically, the alarm may be given by a preset alarm manner, for example, by text or by sound.
It should be noted that the execution sequence of each step in the embodiment of the present invention is not limited, and the embodiment of the present invention provides only one possible implementation manner, that is, monitoring a video stream may be performed before screenshot, or may be performed after screenshot.
Preferably, in the embodiment of the present invention, the video stream is detected before the screenshot, and if an abnormal event of the video stream is detected, the warning information is sent to the relevant person, so that the efficiency can be improved, and if the abnormal event is detected, the abnormal information is also displayed in the motion picture file. For example, if a static frame abnormal event is detected, an alarm is given, and when the screenshot is completed and a moving picture file is displayed on the monitoring terminal, static frame abnormal information is also displayed in the moving picture file.
Step 303: the monitoring server intercepts the animation file from the video stream of each current time period.
If the acquired fragment file is a video stream, executing step 303 specifically includes: and intercepting the moving picture file from the fragment file of the video stream.
The format of the motion picture file is, for example, a GIF format.
In the embodiment of the present invention, when intercepting a moving picture file, the moving picture file with a preset duration may be intercepted, and the moving picture file with a preset number of frames may also be intercepted, which is not limited.
For example, if there are 3 video channels, which are respectively a video channel 1, a video channel 2, and a video channel 3, and the video channel 1 corresponds to a slice file 1, the video channel 2 corresponds to a slice file 2, and the video channel 3 corresponds to a slice file 3, corresponding moving picture files are respectively captured from the slice file 1, the slice file 2, and the slice file 3.
Further, in order to ensure the quality and definition of the motion picture file, the resolution of the motion picture file may be set, for example, set to 320 × 240 in the embodiment of the present invention.
Further, still include: acquiring identifiers of video channels of multiple videos, naming corresponding motion picture files of the video channels of the multiple videos respectively according to the identifiers of the video channels of the multiple videos, and storing the named motion picture files.
Therefore, naming is carried out according to the identification of the video channel, so that the names of the motion picture files corresponding to the same video channel can have the same identification information, the fragment files, the motion picture files, the names and the like of the same video channel can be easily found according to the identification, and the fragment files, the motion picture files, the names and the like can be distinguished from the related files of other video channels.
Step 304: the monitoring server respectively establishes the corresponding relation between the captured multiple moving picture files and the video names of the video channels of the corresponding multi-channel videos, and encapsulates the corresponding relation into a playing page, so that the monitoring terminal loads the playing page.
When step 304 is executed, the method specifically includes:
firstly, according to the identification of the video channels of the multi-channel videos, the video channel names corresponding to the video channels of the multi-channel videos are obtained.
Then, according to the identification of the video channel, a moving picture file corresponding to the video stream of the video channel of the multi-channel video is searched, and a corresponding relation between the plurality of moving picture files which are cut and taken out and the video names of the video channels of the corresponding multi-channel video is established.
For example, the obtained names of the video channel 1, the video channel 2, and the video channel 3 are respectively the Hunan satellite television, the Jiangsu satellite television, and the Zhejiang satellite television, and since the moving picture file is named and stored according to the identifier of the video channel, the name and the corresponding moving picture file can be associated according to the identifier of the video channel.
And finally, writing the corresponding relation between the video names of the video channels of the multi-channel videos and the moving picture files into a playing page.
For example, the dynamic image file is written into an html + css page, so that the monitoring terminal can display the dynamic image files of a plurality of video channels in a page loading mode, and the names of the video channels corresponding to the dynamic image files can be displayed according to the established corresponding relation between the video names and the dynamic image files, so that the display effect of the dynamic image files and the corresponding names is realized, and the display effect is more intuitive.
Further, in order to ensure that the latest moving picture file can be displayed on the monitoring terminal in real time, the embodiment of the present invention further provides an updating method, wherein the playing page is set to be updated according to a second preset period, wherein the second preset period is greater than the first preset period, because the first preset period is an execution period for acquiring the video stream and performing the screenshot, and the second preset period is greater than the first preset period, the latest moving picture file can be intercepted each time the playing page is refreshed, and therefore, the latest moving picture file can be displayed each time the playing page is refreshed.
Step 305: and the monitoring terminal displays the moving picture files and the video names of the video channels of the multiple paths of videos in the playing page by loading the playing page.
Optionally, an embodiment of the present invention provides a display implementation manner, where the monitor terminal displays a moving picture file and a video name of a video channel of multiple videos according to a preset display manner. For example, the display screen is divided into a corresponding number of presentation areas according to the number of video channels, and a moving picture file and a corresponding video name are respectively presented in each presentation area.
Fig. 4 is a schematic view of video monitoring effect according to an embodiment of the present invention. For example, there are 4 video channels, and the names of the video channels are video channel 1, video channel 2, video channel 3, and video channel 4, respectively, so that the display screen of the monitoring terminal can be divided into 4 display areas and displayed respectively.
Specifically, referring to fig. 5, which is a diagram illustrating an actual effect of video monitoring in an embodiment of the present invention, it can be seen from fig. 5 that multiple video channels, such as the Hunan satellite television, the Jiangsu satellite television, and the Zhejiang satellite television, can be simultaneously monitored on one display screen.
Optionally, in the embodiment of the present invention, an alarm implementation manner is further provided, and if the monitoring terminal determines that the displayed motion picture file is abnormal, an alarm is performed. That is to say, in the embodiment of the present invention, the video stream may be subjected to the anomaly detection and the alarm, or the moving picture file may be subjected to the anomaly detection and the alarm.
