Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Now the mainstream browsers on the market, including Google, Firefox, and Safari, have their own protocols for playing live streaming media. The live source (referred to as the rtmp source) cannot be directly opened by the browser, that is, the browser does not support the direct playback of the rtsp source and the rtmp source.

In the prior art, for these rtsp sources or rtmp sources, if you want to play on the browser, some related plug-ins are required, and flash support is required, but current mainstream browsers are abandoning flash and removing plug-ins, which is undoubtedly It brings difficulty to playing live streaming media through a web browser, and reduces the convenience of playing live streaming media.

In addition, different systems support different live source formats. For example, the live source supported by the IOS system platform is in m3u8 format, and the PC or Android platform can play the live source through websocket format.

Based on the above-mentioned defects of the related art, one of the core concepts of the embodiments of the present invention is proposed. After obtaining the rtsp source or the rtmp source, the rtsp source or the rtmp source is converted, so that the terminals of different systems can play the live broadcast corresponding to the terminals of their respective systems. Live streaming in source format.

Please refer to FIG. 1. FIG. 1 shows a flowchart of steps of a method for playing live streaming media provided by an embodiment of the present invention. The method is applied to a browser, and the method may specifically include the following steps:

Step S11, acquiring the rtmp source of the live streaming media to be played.

Step S12, calling a first conversion service to convert the rtmp source into a target source, where the target source is a live broadcast source supported by the browser.

Step S13, playing the live streaming media corresponding to the target source.

In this embodiment, the browser may be various browsers on various devices (pc, Android, ios), such as Chrome, Safari, Firefox, built-in browsers (WeChat, QQ), and the like.

The live streaming media to be played refers to the live streaming media that the user wants to play directly on the browser. For example, a live broadcast of a live broadcast platform.

The target source refers to the live broadcast source of the live streaming media broadcast that the browser supports to play directly. For example, the live source supported by the IOS system platform is the live source in m3u8 format. Therefore, for the browser applied on the IOS system platform, the live source in m3u8 format needs to be obtained, that is, the rtmp source address will be converted through the first conversion service. It is m3u8 source; PC and Android devices can use bilibili open source flv.js to play websocket source. Therefore, for browsers on PC or Android platform, it is necessary to obtain the live source in websocket format, that is, the rtmp source is converted through the first conversion service. Convert to websocket source.

By using the method of the embodiment of the present invention, the live streaming source can be directly played on the browser of the IOS system platform, and the live streaming source can be directly played on the browser of the PC or Android platform, which is convenient and quick.

In this embodiment, the rtsp source corresponds to an rtsp source address, the rtmp source corresponds to an rtmp source address, and the target source corresponds to a target source address. According to the rtsp source address, rtmp source address and target source address, the corresponding rtsp source and rtmp source can be found. source or target source. By acquiring the rtmp source of the live streaming media to be played, and then calling the first conversion service to convert the rtmp source into the target source, the browser can then play the live streaming media to be played for the user to watch.

In this embodiment, the rtmp source corresponds to an rtmp source address, and the first conversion service may obtain the rtmp source through the rtmp source address, and then convert the rtmp source into the target source.

In this embodiment, the first conversion service may be a Node-Media-Server service, and the Node-Media-Server service is a set of script services written by node.js that can convert rtmp live broadcast sources into target sources such as m3u8 and websocket.

In this embodiment, when the user wants to directly play the live streaming media to be played on the browser, the user obtains the rtmp source of the live streaming media to be played, calls the first conversion service, and directly converts the rtmp source into the target source. The target source is the live broadcast source that the browser can directly play, so the live streaming media corresponding to the target source can be played directly through the browser without the need for the browser to install additional plug-ins and flash support, which improves the convenience of playing live streaming media, and , the user does not perceive the entire operation process, improving the user experience.

In addition, considering that under normal circumstances, the live streaming sources of live streaming include rtsp sources and rtmp sources, therefore, the obtained sources are not necessarily all rtmp sources, and rtsp sources may also exist. Refer to Figure 2, which is the implementation of this application. For example, the flow chart of the live streaming service provided by the example, in this embodiment, before acquiring the rtmp source of the live streaming media to be played in step S11, the following steps may also be included:

In step SA1, according to the live broadcast identifier of the to-be-played live streaming media live broadcast, the interface of the live streaming media live broadcast service is invoked, and it is judged whether the rtsp source of the live streaming media live broadcast to be played can be obtained.

Step SA2, in the case that the rtsp source can be obtained, start the conversion process.

Step SA3, using the conversion process to obtain the rtmp source.

In this implementation, the live broadcast identifier is an identifier used to search for the live streaming media to be played when the user accesses the live broadcast with the browser client. The live broadcast identifier can be a room ID or a live broadcast number, and each live streaming corresponds to a specific live broadcast. logo.

The live streaming service refers to the service of obtaining the source address of the target source according to the requested live broadcast identifier, and the target source address can be accessed by the browser to obtain the target source.

When accessing the live broadcast through the browser client, request the interface of the live streaming service, pass in the live broadcast identifier, and call the live streaming service interface according to the live broadcast identifier. At this time, it is necessary to determine whether the to-be-played streaming media corresponding to the live broadcast identifier can be obtained. The rtsp source of the live broadcast, specifically, if the rtsp source can be returned, it means that the live broadcast is being performed and there is a live stream, then the rtsp source of the live streaming media to be played can be obtained, and a corresponding rtsp source address can be obtained.

Since the rtsp source cannot be directly converted to the live source supported by the browser, but the rtmp source can be converted to the source supported by the browser, therefore, if the user wants to play the live streaming source directly on the browser, after obtaining the rtsp source, you can Start the conversion process, convert the rtsp source into an rtmp source, and obtain a corresponding rtmp source address, and then use the rtmp source to convert the rtmp source into a live source in a format supported by the browser after obtaining the rtmp source.

In this embodiment, the conversion process may be an ffmpeg process, and the conversion process may be included in the live streaming service, or may be independent of the live streaming service. In this embodiment of the present invention, the conversion process is included in the live streaming service. Explain in detail.

The ffmpeg process is an open source computer program used to record, convert digital audio and video, and convert it into a stream, which can be executed by the called Process.

In practice, the user may need to play multiple live streaming media in the browser, so there may be multiple conversion processes at the same time. At this point, you can use Task to enable multithreading to call Process to execute the ffmpeg program, and perform the conversion process from rtsp to rtmp source.

By using the method of this embodiment, not only can the rtmp source be converted, but also the rtsp source can be converted, so that the browser can directly play the live streaming media of the rtmp source and the rtsp source.

Referring to FIG. 3, FIG. 3 is a flowchart of a streaming media live broadcast method provided by an embodiment of the present invention. In one embodiment of the present invention, since the live streaming media live broadcast to be played corresponding to the incoming live broadcast identifier may not be live broadcast, there is no live broadcast. stream, at this time, the rtsp source of the live streaming media to be played cannot be obtained, that is, the rtsp source returned after calling the live streaming service interface is empty, it will not enter the conversion process, and an error message false will be returned.

For example, if a user wants to view a live program of a live broadcast platform, the live broadcast program is the live streaming media broadcast to be played, and the room ID (live broadcast identifier) of the live broadcast program is 101. Enter the room ID101 in the search window of the browser, If the live program is not live, an error message will be returned to the browser and displayed on the browser interface for the user to view, so that the user can know the status of the live streaming media to be played.

Continue to refer to FIG. 3 , in an embodiment of the present invention, a static dictionary is established in the streaming media live service, and the static dictionary is used to store the rtsp source address corresponding to the rtsp source and the target source address corresponding to the target source. Association relationship, in this embodiment, in step SA3, the conversion process is used to obtain the rtmp source, which may specifically include the following steps:

Step SB1, query whether the static dictionary stores the association relationship between the rtsp source address and the target source address.

Step SB2, in the case that the static dictionary is queried to store the association relationship between the rtsp source address and the target source address, directly obtain the rtmp source.

In this embodiment, since it can be queried that the static dictionary stores the association relationship between the rtsp source address and the target source address (websocket address and m3u8 address), it means that the requested live broadcast through the ffmpeg service has been performed before. The operation of identifying the corresponding rtsp source to convert the rtmp source, therefore, when the association relationship between the rtsp source address and the target source address is stored in the static dictionary by subsequent query, the corresponding rtmp source can be directly obtained.

Convert the rtsp source corresponding to the requested live broadcast ID to the rtmp source through the ffmpeg service, and can return the rtsp source address corresponding to the rtsp source, the rtmp source address corresponding to the rtmp source, and the target source address corresponding to the target source. The returned target source address includes websocket There are two kinds of address and m3u8 address, and then the Node-Media-Server service is used to select the corresponding target source address according to the platform system where the browser works and send it for the browser to access. The browser accesses the target source address to obtain the target source, so as to realize playback and waiting Live streaming capabilities.

Of course, the returned target source address can also be based on the platform system on which the browser works, and only include either the websocket address or the m3u8 address, which is not limited here.

In this embodiment, the static dictionary is equivalent to a book, and is used to store a correspondence or association between the rtsp source address corresponding to the requested live broadcast identifier and the target source address. Since the rtmp address is confidential and cannot be exposed, the static dictionary In the dictionary, it is better to establish the association between the rtsp source address and the target source address.

The static dictionary stores key-value key-value pairs. There can be multiple key-value key-value pairs. The rtsp source address is the key in the dictionary. The value value stores a class class, which can contain the websocket address and These two fields of m3u8 address. For example, taking the PC or Android platform as an example, the requested live broadcast ID is 1208, the streaming media live broadcast service obtains the rtsp source according to 1208, and obtains a corresponding rtsp source address, where the rtsp source address is the key in the static dictionary, according to The rtsp source address can be queried in value to a websocket address (the address accessed by the PC or Android platform browser) and an m3u8 address (the address accessed by the iOS platform browser), for example, the websocket address is ws://127.0.0.1/ 1208.flv, the address of m3u8 is http://127.0.0.1:8000/1208/index.m3u8.

In this embodiment, after the rtsp source address is obtained and the conversion process is started, it is first possible to query whether there is an rtsp source address corresponding to the requested live broadcast identifier in the static dictionary, and the value is the value associated with the rtsp source address corresponding to the requested live broadcast identifier. The key-value pair of the target source address, if the key-value pair exists in the query, it means that the static dictionary stores the relationship between the rtsp source address and the target source address, and the rtsp source corresponding to the live broadcast identifier has been converted to rtmp request, at this time, the conversion process can directly use the association relationship to obtain the rtmp source address associated with the rtsp source address, and then access the rtmp source address to obtain the rtmp source, and use the rtsp source address stored in the static dictionary and all the rtmp source addresses. The relationship between the target source addresses can be directly obtained according to the rtsp source, and the rtmp source can be obtained, and the corresponding rtsp source address and target source address can be obtained, so as to save the conversion time of the conversion process.

Continuing to refer to FIG. 3 , in an embodiment of the present invention, if the static dictionary is queried whether the association between the rtsp source address and the target source address is stored, it is not found that the rtsp source is stored in the static dictionary. The relationship between the address and the target source address. For example, the streaming media live service is the first time to execute the service that requests the rtsp source corresponding to the live broadcast identifier. At this time, there is no rtsp source corresponding to the requested live broadcast identifier pre-stored in the static dictionary. and the rtsp source address, let alone a key-value pair about the rtsp source address corresponding to the live broadcast identifier and the target source address associated with the rtsp source address. In this embodiment, after querying whether the static dictionary stores the association relationship between the rtsp source address and the target source address, the following steps may be further included:

Step SC1, in the case where the association relationship between the rtsp source address and the target source address is not stored in the static dictionary, call a second conversion service to convert the rtsp source into the rtmp source, and at the same time Returns the destination source address.

Step SC2: Obtain the converted rtmp source and the target source address.

In this embodiment, if the static dictionary is not queried to store the relationship between the rtsp source address and the target source address, the rtmp source cannot be directly obtained. In this case, the second conversion service can be called to convert the The rtsp source is converted into the rtmp source, and the target source address is returned at the same time, and the converted rtmp source can be obtained after the conversion.

In this embodiment, the second conversion service may be a service of a process in the ffmpeg process that converts the rtsp source into the rtmp source.

Referring to FIG. 2 and FIG. 3, in this embodiment, in order to save the computing cost of the system, after acquiring the converted rtmp source and the target source address in step SC2, the following steps may be further included:

Step SD1, establish an association relationship between the rtsp source address corresponding to the rtsp source and the target source address corresponding to the target source.

Step SD2, adding the association relationship between the rtsp source address and the target source address into the static dictionary.

In step SD3, when the rtsp source is obtained again, the association relationship between the rtsp source address corresponding to the rtsp source and the target source address is queried from the static dictionary, and the rtmp source is directly obtained.

In this embodiment, after the second service calculation, the rtmp source corresponding to the rtsp source can be obtained, the rtsp source address corresponding to the rtsp source and the target source address corresponding to the target source can be obtained at the same time, so the rtsp source address and the corresponding rtsp source address can be established. The association relationship of the target source address, and the established association relationship between the rtsp source address and the target source address is added to the static dictionary, that is, a key-value key-value pair is added to the static dictionary. The operation of converting the rtsp source corresponding to the requested live broadcast identifier to the rtmp source has been performed through the ffmpeg service. Therefore, after obtaining the rtsp source according to the live broadcast identifier again, it can be queried that the static dictionary stores the rtsp source address and the described rtsp source. When the target source address is associated, the corresponding rtmp source can be obtained directly, and the target source address can be directly obtained without calling the second conversion service for conversion again, which can avoid calling the second conversion service every time the rtsp source is obtained. Conversion, saves the computational cost of the second conversion service and can save conversion time.

In one embodiment of the present invention, it is considered that during the running process of the conversion process, its running state can be monitored. For example, after entering the conversion process, under normal circumstances, the rtsp source always exists, that is, the live broadcast source always exists. The conversion process can be monitored as normal, that is, the rtmp source can be continuously obtained. However, when the live source is suddenly disconnected and the rtsp source does not exist, the conversion process can be monitored as abnormal, that is, the rtmp source cannot be obtained. In this embodiment, after starting the conversion process, the following steps may be specifically included:

Step SE1, in the case that the rtmp source cannot be acquired by the conversion process, exit the conversion process, and query whether the association between the rtsp source address and the target source address is stored in the static dictionary.

Step SE2, in the case where the association between the rtsp source address and the target source address is stored in the static dictionary, delete the association between the rtsp source address and the target source address from the static dictionary .

Taking the conversion process to an ffmpeg process as an example, Process calls ffmpeg to monitor the running status of the ffmpeg process, monitor whether the rtmp source can be obtained through the ffmpeg process, and monitor the exit of the ffmpeg process. Therefore, if it is monitored that the rtmp source cannot be obtained through the ffmpeg process, the ffmpeg process can be exited, and at the same time, the static dictionary can be queried whether the relationship between the rtsp source address and the target source address is stored. The association relationship between the rtsp source address and the target source address is stored in the static dictionary, and the key-value pair in the static dictionary is directly deleted. If the static dictionary is not queried to store the rtsp source address and the The association relationship between the target source addresses does not require any operation, and the method of this embodiment can process the key-value pairs in the static dictionary in time, ensure the accuracy of the key-value pairs in the static dictionary, and improve the conversion efficiency of the subsequent conversion process.

In one embodiment of the present invention, considering that the static dictionary is limited in size, when reading a piece of data from the static dictionary, the smaller the amount of data in the static dictionary, the faster the reading speed, so the static dictionary stores The key-value pair that expresses the association between the rtsp source address and the target source address is managed. For example, a static dictionary such as a user who starts playing multiple live sources at the same time, when the user does not want to play one of the live sources, normally exits one of the live sources. In this conversion process, the key-value pair expressing the association between the rtsp source address and the target source address in the static dictionary will not be deleted, so the key-value pair will be retained in the static dictionary, but the live source will be disconnected after a period of time. Open, that is, the rtsp source does not exist, and it is meaningless to store the association relationship between the rtsp source address and the rtmp source address in the static dictionary. In this embodiment, the method may also include the following steps:

Step SF1, periodically judging whether the association relationship between the rtsp source address and the target source address stored in the static dictionary is available, wherein, when the rtsp source corresponding to the rtsp source address does not exist, the rtsp source address The association with the target source address is not available

Step SF2, in the case where the association relationship between the rtsp source address and the target source address stored in the static dictionary is unavailable, delete the relationship between the rtsp source address and the target source address from the static dictionary. connection relation.

In this embodiment, it is periodically determined whether the association between the rtsp source address and the rtmp source address in the static dictionary is available. Specifically, a polling task is added to check whether the key-value value in the polling dictionary is available, that is, the rtsp source is checked. Whether the rtsp source corresponding to the address exists, if not, delete the key-value pair.

In this embodiment, the polling period may be set to 5 minutes, or may be set to 10 minutes, which is not specifically limited here.

In this embodiment, by periodically judging whether the association relationship between the rtsp source address and the rtmp source address in the static dictionary is available, and deleting the key-value pair when unavailable, the unavailable key-value pair in the static dictionary can be deleted in time to ensure the static dictionary The key-value pairs in are within the limited range, which improves the query and reading speed of static dictionaries.
