Fig. 3 is a flowchart of a video playing method according to an embodiment of the present invention. The execution subject of the embodiment of the present invention is a terminal, and referring to fig. 3, the method includes:
301. the terminal generates a connection pool.
The terminal can be a mobile phone, a tablet computer, a personal computer and the like, can be provided with a client of the video application, can communicate with a server of the video application through the client, and can play videos through the client.
The connection pool is used for storing at least one connection object between the terminal and the server. The connection pool may be an array, where each location in the array is used to store a connection object. The connection pool may be cached in the memory of the terminal. The maximum number of connection objects in the connection pool may be determined according to the setting operation, for example, 2 to 3 connection objects may be included in the connection pool.
The connection object is used to indicate a connection between the terminal and the server. In particular, the connection object may encapsulate a method for connection (english: method), such as an encapsulation handshake method, a network connection method, and a network flow method. The connection refers to a communication link between the terminal and the server, and may be a Real Time Messaging Protocol (RTMP) connection, which may be used to transmit a video stream.
Regarding the timing of generating the connection pool, for example, the terminal may generate the connection pool when receiving a start instruction for a video application. The start instruction may be triggered by a click operation on an icon of the video application. As another example, the terminal may generate the connection pool when displaying the interface of the video application. For another example, the terminal may generate the connection pool when starting power up, which is not limited in this embodiment. In addition, the process of generating the connection pool may be specifically performed by a client of a video application in the terminal.
Specifically, the generation process of the connection pool may include the following steps one to three:
step one, a terminal receives a domain name of a server.
The domain name is used to identify the address of the server, for example, if the terminal and the server communicate based on the RTMP protocol, the domain name of the server can be RTMP:// XXXX. Regarding the process of receiving a Domain Name, in one possible implementation, the terminal may send a Domain Name request to a Domain Name System (DNS) server, receiving the Domain Name of the server for the video application sent by the DNS server. In another possible implementation, the terminal may send a domain name request to the server of the video application, and receive the domain name sent by the server of the video application.
And step two, the terminal generates at least one connection object according to the domain name of the server.
Optionally, the process of generating any connection object may include: the terminal generates a flow identifier, adds the flow identifier to the domain name to obtain an identifier of a connection object, and encapsulates an object corresponding to the identifier of the connection object with a method for connection to obtain a connection object. In the process of generating the flow identifier, the terminal may generate a random number, use the random number as the flow identifier, and may also obtain a preset flow identifier, which is not limited in this embodiment.
And step three, for each connection object in the at least one connection object, the terminal establishes connection with the server based on the connection object.
Specifically, the connection between the terminal and the server may include a handshake connection, a network connection, and a network flow connection, and accordingly, step three may include the following steps 3.1 to 3.3.
And 3.1, the terminal performs handshake with the server based on the connection object.
The handshake refers to a process of mutually agreeing on the states of the operation modes before information exchange is performed, that is, a process of establishing communication parameters between the receiving end and the transmitting end. The terminal may establish communication parameters with the server before obtaining the live stream from the server.
Specifically, the handshake phase in the RTMP protocol is usually completed by the terminal and the server sending three blocks, where the blocks sent by the terminal are denoted as C0 block, C1 block, and C2 block, and the blocks sent by the server are denoted as S0 block, S1 block, and S2 block. Wherein a block refers to a message fragment. The specific interaction process of the terminal and the server in the handshake phase may include the following steps 3.1.1 to 3.1.4:
and 3.1.1, the terminal sends the C0 block and the C1 block to the server.
And 3.1.2, after receiving the C0 block or the C1 block of the terminal, the server sends an S0 block and an S1 block to the terminal.
And 3.1.3, after the terminal receives the S0 block and the S1 block of the server, sending the C2 block to the server. When the server gets the C0 block and the C1 block, the S2 block is sent to the terminal.
And 3.1.4, after the terminal receives the block S2, other data can be sent to the server, and after the server receives the block C2, other data can be sent to the terminal.
And 3.2, the terminal establishes network connection with the server based on the connection object.
Wherein the network connection is a basic connectivity between the terminal and the server. The terminal can establish a network connection with the server, and the server and the terminal establish the network connection but cannot support video streaming.
Specifically, the terminal may transmit a connection (english: connect) command message to the server, requesting the application of the server to establish a connection. After receiving the connection command message, the server may send a confirmation Window Size (english) protocol message to the terminal, and connect with the application indicated by the connection command message. The server may also send a set bandwidth protocol message to the terminal. After the terminal processes the message of setting the bandwidth protocol, the terminal can send a protocol message for confirming the size of the window to the server. The server may return a message of successful connection after connecting to the application program, and may also send a Stream start (english: Stream Begin) message in the user control message to the terminal, and the server may send a result message in the command message to the terminal, the result message being used to notify the status of the connection.
And 3.3, the terminal establishes a network flow with the server based on the connection object.
Wherein the network stream connection represents a channel for transmitting multimedia data, and the terminal can establish a plurality of network streams with the server.
Through the above process, the terminal can only perform basic message interaction with the application program of the server, but cannot transmit the video stream, so that the terminal can send a create stream (english: creatstreamable) command in the command message to the server at the stage of establishing the network stream connection, and after receiving the create stream command, the server can send a result (english: result) in the command message, wherein the result is used for notifying the terminal of the state of the network stream. A network stream connection has been established between the terminal and the server and a video stream can be transmitted between the terminal and the server.
Through the steps 3.1 to 3.3, the terminal executes three processes of handshaking, network connection establishment and network flow establishment in advance before pulling the stream, so that the three processes of handshaking, network connection establishment and network flow establishment are not required to be executed again during pulling the stream, and the time occupied by the three processes during pulling the stream is saved, so that the total duration of pulling the stream is reduced, the speed of acquiring the video stream is increased, and the speed of watching the video by a user is increased.
And step four, adding the connection object to the connection pool by the terminal.
Through the steps one to three, the terminal creates an available connection, and then a connection object corresponding to the connection can be added to the connection pool, so that the connection can be acquired from the connection pool when the video is played subsequently. By analogy, a plurality of connection objects can be added into the connection pool by executing the steps one to three for a plurality of times, so that the connection pool stores the plurality of connection objects.
Alternatively, the connection indicated by each connection object in the connection pool may be available status. In particular, for each connection object in the connection pool, the terminal can keep the connection indicated by the connection object available by interacting with the server, avoiding that the connection is released because it has not interacted with the server for too long. In one possible implementation, the process of maintaining the connection in the available state may include the following steps one to three:
step one, the terminal sends heartbeat messages to the server every other preset time length based on the connection indicated by the connection object.
The heartbeat message is used for maintaining the connection between the terminal and the server, and can test whether the server is in an online state or not. The heartbeat message may be, for example, a ping frame in a ping-pong (english: ping) communication. The preset time period may be 5 seconds.
And step two, the server receives the heartbeat message and sends a heartbeat response to the terminal.
The heartbeat response is used to confirm that the server is online, and may be, for example, a pong frame in a pingpong communication. Optionally, the content carried by the heartbeat response may be the same as the content carried by the heartbeat message, for example, a protocol field of the heartbeat message may be modified, and the modified heartbeat message is used as the heartbeat response.
And step three, the terminal receives the heartbeat response of the server based on the connection indicated by the connection object.
For the connection indicated by any connection object in the connection pool, when the terminal receives the heartbeat response of the server based on the connection, the connection between the terminal and the server is normal, and therefore the connection can be determined to be in an available state. And when the terminal does not receive the heartbeat response of the server based on the connection, the connection between the terminal and the server is disconnected, so that the connection can be determined to be in an unavailable state, and the corresponding connection object can be released.
Optionally, after the preset duration, the terminal may perform the first to third steps again, so as to interact with the server at regular time, so as to maintain the connection as a long connection.
302. And the terminal receives a video playing instruction.
The video playing instruction is used for indicating the playing of video streams and can be triggered by clicking operation of a live broadcast room. The video playing instruction may carry an identifier of the video stream, where the identifier of the video stream is used to indicate the video stream. The identification of the video stream may be, for example, a room number or stream name of a live room.
303. And the terminal acquires any connection object from the connection pool.
Alternatively, the terminal may traverse at least one connection object in the connection pool, determine whether the connection indicated by each connection object is in an available state, and when the connection indicated by any connection object is in the available state, obtain the connection object, so as to pull the video stream from the server based on the connection indicated by the connection object. When the connections indicated by at least one connection object in the connection pool are all in an unavailable state, the terminal can generate the connection object, and establish the connection with the server based on the connection object, so that the video stream is pulled from the server by reestablishing the connection with the server.
304. The terminal supplements the connection pool.
Specifically, the process of supplementing the connection pool may include the following steps one to two:
step one, a terminal generates a connection object.
And step two, the terminal establishes connection with the server based on the connection object.
And step three, adding the connection object to the connection pool by the terminal.
Further, considering that the terminal can play a plurality of videos in sequence, the terminal can obtain a plurality of connection objects from the connection pool, and then the terminal can generate a plurality of connection objects, establish a connection with the server based on the plurality of connection objects, and add the plurality of connection objects to the connection pool.
