In an embodiment, as shown in fig. 2, a method for pushing a video bitstream is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
step 202, two paths of video code stream data pushed by a video monitoring device are received through a video receiving channel, the video receiving channel is started based on transmission parameter information sent by the video monitoring device, the two paths of video code stream data comprise a first path of code stream data and a second path of code stream data, the first path of code stream data is used for video monitoring and previewing, the first path of code stream data is generated without a fixed period coding key frame, the second path of code stream data is used for recording a video file, and the second path of code stream data is generated by the fixed period coding key frame.
The user can use different types of terminal equipment to log in the cloud server platform, and when different users log in the cloud server platform, the user can initiate viewing requests or downloading requests of monitoring videos in different scenes through triggering operation. The monitoring video refers to a video file collected by monitoring equipment. WebRTC, the name of which is abbreviated from Web Real-Time Communication (English), is an API that supports Web browsers for Real-Time voice conversations or video conversations. WebRTC realizes a web-based video conference, the standard is WHATWG protocol, and the aim is to achieve Real-Time communication (RTC) capability by providing simple javascript through a browser.
Specifically, different monitoring devices can establish connection with the server based on WebRTC. The server can receive two paths of video code stream data pushed by the video monitoring equipment through a video receiving channel, the video receiving channel is started based on transmission parameter information sent by the video monitoring equipment, the two paths of video code stream data comprise a first path of code stream data and a second path of code stream data, the first path of code stream data is used for video monitoring and previewing, the first path of code stream data is generated without a fixed period coding key frame, the second path of code stream data is used for recording a video file, and the second path of code stream data is generated by the fixed period coding key frame. The video monitoring device refers to a device having an image acquisition function in a monitoring system, such as a camera monitoring device. The code stream (Data Rate) is the number of times that a communication port changes high and low levels when transmitting Data in 1 second, and is also called a code Rate, and the more Data is transmitted per unit time, the more information is contained, and it is the most important part in picture quality control in video encoding. The code stream data refers to data in standard formats of audio and video transmitted on the internet according to a real-time streaming protocol. The video stream data may include a plurality of frames of images arranged in sequence, and the transmission of the video stream data refers to the transmission of the plurality of frames of images through the video stream in sequence. After the WebRTC connection is established between the server and the video monitoring device, the server may negotiate with the monitoring device to transmit parameter information corresponding to video stream data. For example, after the WebRTC connection is established between the server and the video monitoring device, the video monitoring device may send the generated SDP information to the server through the WebRTC connection, and complete exchange of the SDP information with the server, that is, the video monitoring device and the server complete negotiation of related transmission parameter information, the server may open a corresponding video receiving channel according to the transmission parameter information included in the SDP information, and the opened video receiving channel is used to receive video code stream data pushed by the video monitoring device. The SDP refers to Session Description Protocol (Session Description Protocol or SDP for short) and describes initialization parameters of streaming media. Because the WebRTC media information interaction needs to use the SDP data format, when the monitoring device needs to transmit video stream data to the server, the server needs to first acquire SDP file information, and then open a corresponding video receiving channel to transmit corresponding video stream data through transmission parameter information included in the SDP information.
And step 204, storing two paths of video code stream data.
After the server receives the two paths of video code stream data pushed by the video monitoring equipment through the video receiving channel, the server can store the two paths of video code stream data. The first path of code stream data is used for video monitoring and previewing, the first path of code stream data is generated without adopting a fixed period coding key frame, the second path of code stream data is used for recording a video file, and the second path of code stream data is generated by adopting a fixed period coding key frame. The key frame is used for describing all information of the compressed image and can restore the image, and the non-key frame is used for compensating the information of the key frame and gradually optimizing the image effect. Therefore, after the server stores the two paths of video code stream data sent by the monitoring device, when the server receives different requests sent by the user terminal, the server can send different code streams to the corresponding user terminal, for example, after the user terminal establishes a connection with the cloud server based on WebRTC, the user terminal can subscribe to view a real-time monitoring video pushed by the monitoring device, and can view and download a video file recorded by the cloud server.
In this embodiment, two paths of video code stream data pushed by the video monitoring device are received through the video receiving channel, and the video receiving channel is opened based on the transmission parameter information sent by the video monitoring device. The two paths of video code stream data comprise a first path of code stream data and a second path of code stream data, the first path of code stream data is used for video monitoring and previewing, and the first path of code stream data is generated without adopting a fixed period coding key frame. The second path of code stream data is used for recording video files, and the second path of code stream data is generated by adopting fixed period coding key frames and stores two paths of video code stream data. Therefore, various code stream data can be provided, the types of the code stream data are enriched, the code stream data are adapted to different application scenes, the monitoring videos can be checked by the user terminal through an external network in real time in different scenes, and the monitoring video files recorded by the cloud server can be downloaded.
In an embodiment, as shown in fig. 3, before receiving two paths of video code stream data pushed by a video monitoring device through a video receiving channel, the method further includes a step of opening the corresponding video receiving channel according to the transmission parameter information, which specifically includes:
And step 304, returning a corresponding acceptance response according to the WebRTC connection request, and establishing WebRTC connection with the video monitoring equipment.
And 308, opening a corresponding video receiving channel according to the transmission parameter information.
Before the server receives two paths of video code stream data pushed by the video monitoring equipment through the video receiving channel, when the server receives a WebRTC connection request sent by the video monitoring equipment, the server can return a corresponding receiving response according to the WebRTC connection request, and the WebRTC connection is established with the video monitoring equipment. After the WebRTC connection is established between the server and the video monitoring device, the server can receive transmission parameter information sent by the video monitoring device through the WebRTC connection, and the server opens a corresponding video receiving channel according to the transmission parameter information to receive code stream data sent by the video monitoring device. Because the WebRTC media information interaction needs to use an SDP data format, after the server establishes WebRTC connection with the video monitoring device, the server can receive SDP information sent by the video monitoring device through the WebRTC connection, and the server opens a corresponding video receiving channel according to transmission parameter information included in the SDP information. Therefore, based on the WebRTC connection, the corresponding video receiving channel can be opened according to the transmission parameter information contained in the SDP information, different video code stream data can be pushed to the server, and the types of the code stream data are enriched so as to adapt to different application scenes.
In an embodiment, as shown in fig. 4A, after storing two paths of video code stream data, the method further includes a step of forwarding the two paths of video code stream data, which specifically includes:
and 402, forwarding the first path of code stream data to a corresponding user terminal.
And step 404, forwarding the second path of code stream data to a recording server.
The server receives the two paths of video code stream data pushed by the video monitoring equipment through the video receiving channel, and after the two paths of video code stream data are stored, the server can forward the two paths of video code stream data. Specifically, the server may distribute the received code stream data, forward the corresponding first path of code stream data to a user subscribing to the video monitoring device, and forward the corresponding second path of code stream data to the recording server. That is, the server may forward the first path of code stream data to the corresponding user terminal, and forward the second path of code stream data to the recording server. The first path of code stream data is used for video monitoring and previewing, and is characterized in that a fixed period coding key frame is not adopted, the consumed bandwidth is the same with the image quality, the data volume of the key frame is far larger than that of a non-key frame, and the fixed period coding key frame is not adopted in the first path of code stream data, so that the data volume can be effectively reduced, and the consumption of the bandwidth is reduced under the same with the image quality, such as the coding data volume of a P frame. The second path of code stream data is used for recording a video file, and the path code stream data is characterized in that key frames are encoded at fixed periods, for example, every 30 frames, so that the recorded file can support progress dragging during playing. Fig. 4B is a schematic diagram of an architecture of video stream pushing. When different user terminals log in the cloud server platform by using the browser, the user terminals can check and preview real-time monitoring videos and download video files recorded by the cloud server. The user terminal can also subscribe the plug flow of the video monitoring equipment on the cloud server by using the browser supporting the WebRTC, and automatically acquires the corresponding plug flow. Therefore, the cloud server can automatically forward the video code stream data subscribed by the user terminal. Meanwhile, video file index and video file downloading services for inquiring and recording by mobile equipment and PC equipment are provided, monitoring videos in different scenes are checked on the external network, and convenience is brought to users.
In one embodiment, the step of forwarding the first path of code stream data to the corresponding user terminal includes:
and sending the first path of code stream data to the user terminal through the opened video sending channel, wherein the video sending channel is opened based on the negotiated transmission parameter information.
The user terminal can subscribe the plug flow of the video monitoring equipment on the cloud server by using the browser supporting the WebRTC, and automatically acquires the corresponding plug flow. Specifically, when the cloud server receives two paths of video code stream data pushed by the video monitoring device through the video receiving channel, the server can forward the second path of code stream data to the recording server for recording and storing the recording file. If a user subscribes the plug flow of the monitoring device, the server may forward the first path of code stream data to the corresponding subscribing user. Therefore, various code stream data can be provided, the types of the code stream data are enriched, different application scenes are adapted, and the fact that the user terminal can check the monitoring video in real time through the external network under different scenes is achieved.
In one embodiment, the method further includes a step of sending the second code stream data corresponding to the queried video file to the user terminal, and specifically includes:
and receiving a video file downloading request sent by a user terminal.
And according to the video file downloading request, inquiring the video file from the database, and sending the second path of code stream data corresponding to the inquired video file to the user terminal.
When different user terminals log in the cloud server platform by using the browser, the user terminals can check and preview real-time monitoring videos and download video files recorded by the cloud server. Specifically, when the server receives a video file downloading request sent by the user terminal, the server may query the video file from the database according to the video file downloading request, and send the second path of code stream data corresponding to the queried video file to the user terminal. Therefore, various code stream data can be provided, the types of the code stream data are enriched, different application scenes are adapted, and the fact that the user terminal can download the monitoring video file recorded by the cloud server in different scenes is achieved.
