As shown in fig. 1, the implementation environment includes: the system comprises a collection terminal, a video networking server, a streaming media module and an Internet terminal. The acquisition terminal is connected with the video network server, the video network server is connected with the streaming media module through the video network, and the streaming media module is connected with the internet terminal through the internet.
The acquisition terminal is used for acquiring video data (including audio data and video data) and sending the video data to the video networking server through a video networking protocol, so that the video data in the video networking server are all video networking video data.
In one embodiment, the acquisition terminal may be a video network acquisition terminal, and after the video network acquisition terminal acquires video data, the video network acquisition terminal directly transmits the video data to a video network server through a video network protocol.
In addition, because the video network can realize the real-time transmission of the full-network high-definition video which can not be realized by the internet at present, therefore, the video data collected by the internet collection terminal can be converted into video data of the video network, so that the real-time transmission of high-definition video is realized through the video network, therefore, in one embodiment, the collection terminal may also be an internet collection terminal, such as an internet IPC camera, the internet collection terminal is connected to the transfer server through the internet, the transfer server is connected to the video server through the video network, after the internet collection terminal collects the video data, the video data can be sent to the protocol conversion server, after the protocol conversion server converts the internet protocol video data into the video data of the video internet protocol, and then sending the video data to the video network server, so that the video network server receives the video data.

Referring to fig. 2, fig. 2 is a flowchart of a video data transmission method according to an embodiment of the present invention, as shown in fig. 2, the method may be applied to a streaming media module in a video data transmission system, where the video data transmission system further includes a video networking server and an internet terminal, the video networking server is connected to the streaming media module through a video networking, and the streaming media module is connected to the internet terminal through an internet, and the method specifically includes the following steps:
and step S21, receiving a video display request sent by the Internet terminal.
In this embodiment, the video display request may include a video play request and a video preview request.
The internet terminal can be a computer, a pad or a mobile phone and other intelligent equipment, a user operation interface is provided on the internet terminal, the operation interface can be a web interface or a specially developed client interface, video stream display areas of video data of various video networks are displayed on the operation interface, and a user can select one of the video stream display areas, so that the internet terminal can detect a video display request triggered by the user. Specifically, the selection operation may be a single click, a double click, or a hover operation.
In this embodiment, the video data of the video network may be video data of the video network stored in a video network server, or may also be real-time video data acquired by an acquisition terminal, where the real-time video data and the video data of the video network may be video data in an H264 format.
For example, in a video conference scene, when it is time to speak in a branch conference room, it is usually necessary to push a video stream of the branch conference room onto a large screen of a main conference room, but before pushing the video stream onto the large screen of the main conference room, it is determined that a video of the branch conference room is unproblematic, that is, it is determined that a capture terminal of the branch conference room can capture video data normally, so that the video stream captured by the capture terminal of the branch conference room needs to be previewed first to see whether there is a problem, at this time, a user of an internet terminal may move a mouse to a video stream display area corresponding to the branch conference room on an operation interface, hover the mouse for a preset time, for example, for 2 seconds, at this time, the internet terminal may detect a video preview request, which is triggered by the user and is directed to the capture terminal of the branch conference room, that is, and send the video preview request to a streaming media module, so that the streaming media module may receive a video display request, which is sent by the internet terminal and is directed .
For another example, after it is determined that the collection terminal of the branch meeting place can normally collect video data through previewing, it is determined that the video stream of the branch meeting place is pushed to the large screen of the main meeting place, at this time, a user of the internet terminal can move a mouse to a video stream display area corresponding to the branch meeting place on an operation interface and click the video stream display area, at this time, the internet terminal can also detect a video playing request, which is triggered by the user and is directed to the collection terminal of the branch meeting place, that is, a target collection terminal, and send the video playing request to the streaming media module, so that the streaming media module can receive the video display request, which is sent by the internet terminal and is directed to the target collection terminal.
And step S22, acquiring target video data from the video network server according to the video display request.
In this embodiment, for real-time video data, the streaming media module sends a video stream acquisition request for the target acquisition terminal to the video networking server before the video networking server acquires the target video networking video data, and the video networking server receives the video stream acquisition request and then acquires the real-time video data from the corresponding target acquisition terminal.
Therefore, in this embodiment, the streaming media module obtains the target video data from the video networking server according to the video display request, and actually, the streaming media module sends the video stream obtaining request for the target acquisition terminal to the video networking server, and the video networking server forwards the real-time video data or the video networking video data uploaded by the target acquisition terminal to the streaming media module.
And step S23, converting the target video network video data into RTMP video data.
Because the internet protocol is different from the video networking protocol, the internet terminal cannot process the video networking video data, and therefore, in this embodiment, the target video networking video data is first converted into the RTMP video data based on the TCP protocol by the streaming media module, and then can be processed by the internet terminal.
The RTMP (Real Time Messaging Protocol) is based on TCP, and is a Protocol family, which includes various variants such as RTMP basic Protocol and RTMPT/RTMPs/RTMPE. RTMP is a network protocol designed for real-time data communication, and is mainly used for audio-video and data communication between a Flash/AIR platform and a streaming media/interaction server supporting the RTMP protocol. Software supporting the protocol includes Adobe Media Server/ultraportable Media Server/red5, etc. RTMP is the same as HTTP, and belongs to the application layer of TCP/IP four-layer model.
The video networking video data includes an ethernet header (14 bytes), a video networking switching protocol header (22 bytes), a common header (4 bytes), a user protocol data header (28 bytes), and pure video data.
The RTMP video data includes an ethernet header (14 bytes), an IP protocol header (20 bytes), a TCP protocol header (20 bytes), an RTMP protocol header (variable length), and pure video data.
In an embodiment, the step S23 may specifically include the following steps:
step S231, parsing the target video network video data to obtain an ethernet header, a user protocol data header, and pure video data.
Wherein the user protocol header comprises at least: frame rate, code rate, resolution, and timestamp information.
Step S232, the user protocol data header is encapsulated according to the RTMP protocol, and an RTMP protocol header is obtained.
Step S233, determining the RTMP video data according to the ethernet header, the IP protocol header, the TCP protocol header, the RTMP protocol header, and the pure video data.
In this embodiment, the streaming media module firstly analyzes and processes the video data of the target video network, and obtaining the video data of the target video network includes obtaining the video data of the target video network
In this embodiment, the video data of the video network is transmitted in the video network in the form of a data packet, so that the video data of the video network received by the streaming media module is actually a video data packet of the video network, and the same RTMP video data is also transmitted in the form of a data packet in the video network, so that the RTMP video data converted by the streaming media module is actually an RTMP video data packet, and after the streaming media module receives the video data packet of the video network, the video data packet of the video network is sequentially unpacked and packaged, thereby completing the conversion from the video data packet of the video network to the RTMP video data packet. Wherein, the unpacking process is as follows:
the streaming media module firstly removes an Ethernet header and a video networking exchange protocol header of a video networking video data packet, and the video networking video data packet at the moment becomes: a common header (4 bytes), a user protocol data header (28 bytes), and pure video data;
the streaming media module continues to parse the video networking video data packet, and the common header is removed, at this moment, the video networking packet becomes: a user protocol data header (28 bytes) and pure video data, wherein the user protocol header mainly contains the frame rate, code rate, resolution, time stamp and the like of the video data. At this point the information contained in the user protocol header is saved for later encapsulation of the RTMP data packet.
The streaming media module continues to analyze the video networking video data packet, and the user protocol header is removed, so that the video networking video data packet is left: pure video data, which is true video data.
And after the unpacking process, performing a packaging process, wherein the packaging process comprises the following steps:
the streaming media module encapsulates the video data into RTMP header information according to the frame rate, code rate, resolution, timestamp and the like of the video data contained in the user protocol header acquired by unpacking and according to the RTMP protocol format, and the data format is obtained before the RTMP header information is added to the pure video data acquired in the unpacking process: an RTMP protocol header (variable length) and pure video data;
finally, the streaming media module adds an ethernet data header, a TCP packet header and an IP packet header on the basis of an RTMP protocol header (variable length) and pure video data, and the final format of the RTMP data packet is: ethernet header (14 bytes), IP protocol header (20 bytes), TCP protocol header (20 bytes), RTMP protocol header (variable length), and pure video data.
In an embodiment, the streaming media module may be written in C + + language to improve compatibility of the streaming media module and facilitate the migration of the streaming media module, so that the streaming media module may be installed in a video networking server or the streaming media module may be installed in an internet terminal, where the step S233 may specifically include the following steps:
step S2331, call a network protocol stack of the video networking server, add the ethernet header, the IP protocol header, the TCP protocol header, and the RTMP protocol header to the pure video data, and obtain the RTMP video data.
Step S2332, call a network protocol stack of the internet terminal, add the ethernet header, the IP protocol header, the TCP protocol header, and the RTMP protocol header to the pure video data, and obtain the RTMP video data.
In this embodiment, the streaming media module is used as a program in the video networking server or the internet terminal, and the program can directly call a network protocol stack carried by the video networking server or the internet terminal, for example, when the video networking server or the internet terminal is a server of a Linux system, the streaming media module can call the Linux network protocol stack, and add an ethernet header, an IP protocol header, a TCP protocol header, and an RTMP protocol header to pure video data, thereby obtaining RTMP video data. It should be noted that step S2331 and step S2332 should not be construed as limited to the order of execution.
The video network server or the internet terminal can be provided with double network cards, one network card is connected with the video network, and the other network card is connected with the internet, so that double-network communication of the video network server or the internet terminal can be realized.
In this embodiment, through with streaming media module direct mount on video networking server or internet terminal, can avoid deploying streaming media server alone, resources are saved, simultaneously, also can avoid video networking video data to retransmit between a plurality of servers, improved data transmission efficiency, guarantee video data's real-time.
Step S24, sending the RTMP video data to the internet terminal, so that the internet terminal displays the RTMP video data.
In this embodiment, after the streaming media module converts the target video data into the RTMP video data, the RTMP video data may be returned to the internet terminal, so that the internet terminal can receive the RTMP video data returned by the streaming media module and display the RTMP video data on the interface of the internet terminal.
Specifically, after receiving the RTMP video data, the internet terminal first calls a play plug-in installed in the internet terminal to decode the RTMP video data, and then displays the decoded RTMP video data.
In this embodiment, it is considered that the internet terminal receives data in other data formats because the internet terminal needs the nginx or tomcat service, and at this time, the internet terminal decodes all the received data, thereby distinguishing a data packet of the RTMP protocol, and calls a corresponding plug-in to decode and display a video.
In this embodiment, after receiving a video display request, sent by an internet terminal, for a target acquisition terminal, a streaming media module obtains target video data from the video networking server according to the video display request, converts the target video data into RTMP video data, and sends the target video data to the internet terminal, so that the internet terminal displays the RTMP video data.
In addition, this embodiment can avoid deploying the streaming media server alone through with streaming media module direct mount on video networking server or internet terminal, resources are saved, simultaneously, also can avoid video networking video data to forward between a plurality of servers, has improved data transmission efficiency, further guarantees video data's real-time.
In addition, before the internet terminal displays the video of the target acquisition terminal, that is, before the streaming media module sends the RTMP video data to the internet terminal, the internet terminal needs to perform handshaking, connection establishment, streaming establishment, and playing processes with the streaming media module in sequence.
Referring to fig. 3, fig. 3 is a flow chart of handshaking between a streaming media module and an internet terminal according to an embodiment of the present invention, as shown in fig. 3, C0, C1, and C2 are three fixed-size data blocks, and S0, S1, and S2 are three fixed-size data blocks, and the handshaking procedure is as follows:
the handshake starts when the internet terminal sends C0 and C1, and the server sends S0 and S1 after receiving C0 or C1; when the internet terminal collects S0 and S1, C2 is sent, and when the server collects C0 and C1, S2 is sent; after the client and the server receive S2 and C2, respectively, the handshake is completed.
The connection establishment procedure is as follows:
1. the internet terminal sends a "connect" in a command message to the streaming media module requesting a connection to be established with a service application instance.
2. After receiving the connection command message, the streaming media module sends a confirmation window Size (WindowAcknowledgement Size) protocol message to the internet terminal, and simultaneously connects to the application program mentioned in the connection command.
3. The streaming media module sends a set bandwidth () protocol message to the client.
4. After the internet terminal processes the set bandwidth protocol message, it sends a confirmation window Size (WindowAcknowledgement Size) protocol message to the streaming media module.
5. The streaming media module transmits a "Stream start" (Stream Begin) message in the user control message to the internet terminal, and the streaming media module transmits a "result" (_ result) in the command message to inform the internet terminal of the connection status.
The process of establishing the flow is as follows:
1. the internet terminal transmits a "create stream" (createStream) command in the command message to the streaming media module.
2. After receiving the command of 'creating stream', the streaming media module sends 'result' in the command message to inform the internet terminal of the stream state.
The playing process is as follows:

2. After receiving the play command, the streaming media module sends a set block size (ChunkSize) protocol message.
3. And the streaming media module sends 'streamlogic' in the user control message to inform the Internet terminal of the stream ID.
4. If the play command is successful, the streaming media module sends a response status of "netstream.play.start & netstream.play.reset" in the command message, and informs the internet terminal that the execution of the "play" command is successful.
After finishing the above-mentioned 4 steps of handshaking, establishing connection, establishing stream and playing, the streaming media module sends the RTMP video data to be played by the Internet terminal.

2. Video networking packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
