All the above alternatives can form alternative embodiment of the invention using any combination, herein no longer It repeats one by one.

Fig. 3 is a kind of flow chart of media stream capturing method provided in an embodiment of the present invention.This method can be held by terminal Row, which can be the second terminal 103 in implementation environment shown in Fig. 1, referring to Fig. 3, this method comprises:

301, when starting live streaming in application, terminal pre-establishes target connection, which is connected for obtaining from server Media Stream, the live streaming are applied for providing multiple direct broadcast bands.

Wherein, target connection can be RTMP stream connection, and direct broadcast band is also referred to as direct broadcasting room, and server can be stream matchmaker Body server.

In the embodiment of the present invention, user can carry out start-up operation to live streaming application at the terminal, such as click the live streaming and answer Icon triggers the enabled instruction applied to the live streaming.Terminal can star live streaming and answer when receiving the enabled instruction With, and establish target connection.In a kind of possible implementation, during starting live streaming application, terminal can be initialized Video player, the subsequent Media Stream got is played by the video player, and terminal can also initialize built in advance connection Management module executes the process for pre-establishing target connection by the built in advance connection management module.

Certainly, the embodiment of the present invention is illustrated for only establishing target connection when terminal is in starting live streaming application, real On border, terminal can also click any one direct broadcast band in user, be built with other opportunitys before triggering Media Stream acquisition instruction Vertical target connection, it is not limited in the embodiment of the present invention.

In a kind of possible implementation, before terminal pre-establishes target connection, step 3011 can be executed:

Step 3011, terminal initialization built in advance connecting object pointer variable are sky, obtain domain name.

Wherein, which can be expressed as " PSLinkObjectPtr ", when it is empty " NULL " When, indicate that the pointer variable is not directed toward any object.

In a kind of possible implementation, terminal can send domain name acquisition request to stream media scheduling management server, The domain name of stream media server system, the domain name and terminal are returned from stream media scheduling management server to terminal is obtaining media The IP address for the server that may be accessed when stream is corresponding.

In a kind of possible implementation, terminal can initialize built in advance and connect when initializing built in advance connection management module Pointer to object variable is connect, domain name is obtained, starts a built in advance connection management thread, is responsible for pre-establishing target company by the thread It connects.In a kind of possible implementation, target establishment of connection process may include step 3012 to step 3017:

Step 3012, when built in advance connecting object pointer variable is empty, terminal is that built in advance connecting object pointer variable is distributed Built in advance connecting object, the value for initializing the first attribute of built in advance connecting object, the second attribute and third attribute is first object Value, the value of the 4th attribute are initial time, execute step 3013.

Wherein, for first attribute for describing whether TCP connection has been established, which can use variable " IsTCPAvailable " is indicated；For second attribute for describing whether complete preposition instruction, which can use variable " IsPreCommandFinished " is indicated；For the third attribute for describing whether target connection can be used, which can be with It is indicated with variable " IsALive ", the 4th attribute is used to describe to finally receive the time of user's control message, the 4th attribute It can be indicated with variable " LastRPingTime ".

First attribute, the second attribute and third attribute can there are two value, such as first object value and the second target value, First object value and the second target value may each be logical value, for example, first object value can be False, the second target value can To be True.The value of 4th attribute is the time, and initial time can be 0.

When the value of the first attribute is first object value, expression does not set up TCP connection, when the value of the first attribute is the When two target values, TCP connection is had been established in expression；When the value of the second attribute is first object value, expression does not complete preposition finger It enables, when the value of the second attribute is the second target value, preposition instruction is completed in expression；When the value of third attribute is the first mesh It when scale value, indicates that target connection is unavailable, when the value of third attribute is the second target value, indicates that target connection is available.

Terminal is after the built in advance connecting object pointer variable distributes built in advance connecting object, and built in advance connecting object pointer variable is then It is not sky.

Step 3013, when the value of first attribute is first object value, terminal and server establish TCP connection, such as Fruit fails, and after the second preset duration of suspend mode, deletes the built in advance connecting object, setting built in advance connecting object pointer variable is sky, weight It is new to execute step 3012；If it is successful, the value of first attribute is revised as the second target value, step 3014 is executed.

Domain name, in the step 3013, the corresponding IP of the available domain name of terminal are obtained for terminal in step 3011 (Internet Protocol, Internet protocol) address, server corresponding with the IP address establish TCP connection.For example, eventually End can be translated domain names by DNS (Domain Name System, domain name system) server as corresponding IP address, example Such as, terminal can send domain name analysis request to dns server, and domain name mapping request carries the domain got in step 3011 Name, returns to the corresponding IP address of the domain name by dns server.

Step 3014, when the value of second attribute is first object value, terminal and server carry out multiple preposition fingers The interaction of order after the second preset duration of suspend mode, closes the TCP connection if any instruction fails, and deletes built in advance connection pair As setting built in advance connecting object pointer variable is sky；If it is successful, the value of second attribute and third attribute is revised as The value of 4th attribute is updated to current time by two target values.

Wherein, it is preposition instruction refer to broadcastings (Play) instruction before instruction, it is multiple it is preposition instruction including shake hands instruction, Connect (Connect) instruction and creation stream (CreateStream) instruction.

The interaction that terminal and server carry out multiple preposition instructions includes: that terminal to server initiates RTMP handshake procedure, It shakes hands and sends Connect instruction to server after completing, and wait its response results, then initiated to server CreateStream instruction, and wait its response results.Handshake procedure is for differentiating that terminal and server whether there is； Network connection is set up after Connect is instructed successfully, between terminal and server, but can not also support media flow transmission； It, can be with media stream between terminal and server after CreateStream is instructed successfully.

In a kind of possible implementation, after success carries out the interaction of multiple preposition instructions with the server, terminal can To obtain traffic identifier from the response results that the creation stream instructs, traffic identifier that is to say stream ID (identification, identity mark Know).

Terminal has received the response results of server during carrying out preposition instruction interaction with server, even if The response results are not user's control messages, but still can determine the company between terminal and server by the response results It connects and is available, therefore terminal can once update the value of the 4th attribute.

For server, server receive terminal initiation TCP connection, RTMP shakes hands, Connect is instructed and After CreateStream instruction, respective handling can be carried out.For example, the reception and processing step of instruction can be by the masters of server Process executes.

After terminal pre-establishes target connection, since user not yet clicks any direct broadcast band, terminal needs to maintain The heartbeat of the target connection pre-established, detailed process is referring to subsequent step 302 to step 303.

302, terminal detects the state of target connection, which includes available mode and down state.

Wherein, available mode indicates that terminal can obtain Media Stream from server, no based on the target connection pre-established Available mode indicates that terminal cannot obtain Media Stream from server based on the target connection pre-established.

In the embodiment of the present invention, terminal can carry out information exchange between server, to detect the state of target connection, In a kind of possible implementation, which can be the interaction of user's control message, and correspondingly, which can be with Include the following steps 3021 to step 3023:

Step 3021, terminal are attempted to read the user's control message that the server is sent, and send when reading the server User's control message when, the value of the 4th attribute is updated to current time, determine the target connection state be available State executes step 3022；When the unread user's control message sent to the server, step 3023 is executed.

In the embodiment of the present invention, terminal can carry out user's control message interaction between server, by interaction scenario, To determine the state of target connection.For example, terminal can attempt to read the Ping user's control message from server, if read Ping user's message is got, then to server response Pong user's control message.Since terminal receives the control from server Message processed shows that the target pre-established is connected as available mode, and therefore, terminal can carry out more the value of the 4th attribute Newly.

Correspondingly, server can cross certain time interval with every, based on the target connection pre-established, send to server Ping user's control message, and the Pong user's control message for waiting terminal to respond.For example, sending the step of control message to terminal Suddenly it can be executed by the host process of server.

It should be noted that the embodiment of the present invention is come with carrying out user's control message interaction between terminal and server Determine target connection state for be illustrated, in fact, between terminal and server can also use other interactive modes, Such as the interaction of heartbeat message, to determine the state of target connection, it is not limited in the embodiment of the present invention.

Step 3022, when the state of target connection is available mode, after the first preset duration of terminal sleeping, continue to hold Row attempts the step of reading the user's control message that the server is sent.

Wherein, which was less than between the time that the server sends user's control message Every for example, the time interval that server sends user's control message is 5 seconds, the first preset duration is 1 second.

In the embodiment of the present invention, when terminal detects target connection in available mode, when terminal can be with one section of suspend mode Between after, reattempt read the user's control message from server, wherein the time of suspend mode be less than server send user's control The time interval of message, this sleep mode can save terminal under the premise of not influencing to detect the state of target connection Resource consumption.

Step 3023, terminal obtain current time, judge between the time between current time and the value of the 4th attribute Every whether being greater than prefixed time interval, if so, determining that the state of target connection is down state, if not, suspend mode the After one preset duration, by the step of executing the user's control message for attempting to read server transmission, determine that the target connects State.

Wherein, which is greater than the time interval that the server sends user's control message, for example, server The time interval for sending user's control message is 5 seconds, and prefixed time interval can be 8 seconds.

If the time interval between current time and the value of the 4th attribute is greater than prefixed time interval, show in advance There are risk, target connection is unavailable for the target connection of foundation.If time interval is less than prefixed time interval, suspend mode one After the section time, continue state-detection.

It should be noted that the step 3023 is according between the time between current time and the value of the 4th attribute Every, determine the target connection state a kind of possible implementation.By being controlled according to current time with user is finally received Difference between the time of message processed can accurately learn whether normally carrying out user's control between terminal and server The interaction of message, so that it is determined that the state of target connection.

303, when the state of target connection is down state, terminal re-establishes target connection.

In a kind of possible implementation, it includes: the shape when target connection that terminal, which re-establishes the process that target connects, When state is down state, after the second preset duration of suspend mode, the connection of built in advance pointed by built in advance connecting object pointer variable is closed The TCP connection of object, and built in advance connecting object pointed by built in advance connecting object pointer variable is deleted, built in advance connection pair is set As pointer variable be sky, re-execute pre-establish target connection the step of, that is to say, re-execute the steps 3012 to step 3014.Wherein, compared to the first preset duration, the second preset duration be can be set shorter, and such as 10 milliseconds.

Reliable target can be kept to connect by step 302 to step 303, between terminal and server, to guarantee For user when clicking direct broadcast band, terminal directly can obtain Media Stream from server using target connection.

304, when receiving the Media Stream acquisition instruction to any direct broadcast band, terminal is connected based on the target, from this Server obtains the Media Stream of the direct broadcast band.

In the embodiment of the present invention, terminal can show multiple live streamings frequency that live streaming application provides after starting live streaming application Road, user can carry out clicking operation to any one direct broadcast band, trigger the Media Stream acquisition instruction to the direct broadcast band, After terminal receives the Media Stream acquisition instruction, it can be broadcast to the Media Stream of the server request direct broadcast band It puts.

In a kind of possible implementation, is connected based on the target, the Media Stream of the direct broadcast band is obtained from the server Include the following steps 3041 to step 3046:

Step 3041, when receiving the Media Stream acquisition instruction to any direct broadcast band, terminal obtains the direct broadcast band Stream address and stream title.

In the embodiment of the present invention, live streaming application provide all direct broadcast bands be corresponding with stream address and stream title, when with When any one direct broadcast band is clicked at family, terminal can be obtained according to the corresponding relationship between direct broadcast band and stream address and stream title Get stream address (StreamURL) and stream title (StreamName) of the direct broadcast band that user is clicked.

In a kind of possible implementation, stream media scheduling management server can store the mark and stream of direct broadcast band Corresponding relationship between address and stream title, when terminal detects that user clicks the operation of any one direct broadcast band, terminal can It is requested with being sent to stream media scheduling management server, which carries the mark for the direct broadcast band that user is clicked, Streaming Media Management and running server can according to terminal send direct broadcast band mark, inquire corresponding relationship, by corresponding stream address with Stream title is sent to terminal, so that terminal gets stream address and the stream title of direct broadcast band.

Step 3042, terminal judge whether the value of built in advance connecting object pointer variable is empty, if so, executing step 3044, if not, executing step 3043.

Terminal can first judge whether the value of built in advance connecting object pointer variable is sky, if it is sky, shows to build in advance Vertical target connection is unavailable, then terminal can execute step 3043, if being not sky, terminal, which can execute, reads third category The step of property.

Step 3043, terminal judge the third attribute of built in advance connecting object pointed by built in advance connecting object pointer variable Whether value is first object value, if so, step 3044 is executed, if not, executing step 3045.

When the value of third attribute is first object value, indicate that target connection is available, when the value of third attribute is not When first object value, indicate that target connection is unavailable.

Step 3044, terminal are based on the stream address, obtain Media Stream from the server.

In the embodiment of the present invention, when the built in advance connecting object pointer variable is empty, terminal executes the step 3044, or, When the built in advance connecting object pointer variable is not empty, and the value of the third attribute is the first object value, terminal executes should Step 3044.

The step 3044 is that terminal is based on stream address, executes normal Media Stream and obtains process, the acquisition process of Media Stream It may include: after terminal establishes TCP connection and carry out preposition instruction interaction with server, based on stream address, to be sent to server Play instruction (Play instruction) receives the Media Stream that server returns.
