Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
At present, mainstream browsers in the market, including Google, Firefox, Safari and the like, all have their own live streaming media playing protocols, and for live streaming media source formats, that is, live streaming sources in rtsp format (rtsp source for short) or live streaming sources in rtmp format (rtmp source for short), the browsers cannot be directly opened, that is, the browsers do not support the browsers to directly play the rtsp source and rtmp source.
In the prior art, for these rtsp sources or rtmp sources, playing on a browser requires some related plug-ins and flash support, but current mainstream browsers discard flash and remove plug-ins.
In addition, authentication services are essential for live broadcasting. The authentication service can prevent the user from stealing related live broadcast information, and protect the privacy and traffic protection of the user. Therefore, how to safely play the streaming media live broadcast on the browser without the support of flash and plug-in becomes a problem to be solved
Based on the above problems of the related art, one of the core concepts of the embodiments of the present invention is provided, and an authentication service is provided from a streaming media live source to the whole process of playing by a browser in a scenario where streaming media live is played on a browser which discards flash and is depacketized, so that streaming media live can be safely played on a browser which discards flash and is depacketized.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a live streaming media playing method according to an embodiment of the present invention, where the method is applied to a live streaming server, and the method specifically includes the following steps:
step S11, a play request sent by the browser is obtained, where the play request carries a first timestamp, first encryption information, and a play address.
And step S12, performing authority authentication on the play request according to the first timestamp and the acquisition time of the play request.
Step S13, when the first authorization authentication for the play request passes, performing a second authorization authentication for the play request according to the first timestamp, the first encryption information, and a local preset key.
And step S14, sending the target video stream stored in the play address to the browser when the secondary authority authentication on the play request passes, so that the browser plays the target video stream.
In this embodiment, the browser may be various browsers on various devices (pc, Android, ios), such as Chrome, Safari, Firefox, a built-in browser (WeChat, QQ), and the like, but it is directed to a scenario in which these browsers do not develop a browser plug-in nor support flash.
When the browser needs to play the streaming media live broadcast, firstly, a play request is sent to a live broadcast server, the live broadcast server can receive the play request sent by the browser, authority identification is carried out on the play request, if the authority identification is passed, a target video stream stored under a play address can be sent to the browser, after the browser receives the target video stream, the target video stream can be played, namely the streaming media live broadcast is played, the target video stream refers to a video stream corresponding to the streaming media live broadcast and directly played by the browser without using a plug-in or a flash, namely the video stream corresponding to the streaming media live broadcast and desired to be watched by a user in the browser.
For browsers which do not develop browser plug-ins and do not support flash, the formats of live broadcast sources supported by browsers of different systems are different, for example, live broadcast sources supported by browsers of an IOS platform are in m3u8 format, and browsers of a PC or Android platform can play live broadcast sources through websocket format. Therefore, in this embodiment, if the browser is of the IOS system platform, the format of the target video stream is m3u8 format, and if the browser is of the PC or Android platform, the format of the target video stream is websocket format.
In this embodiment, the play request received by the live broadcast server needs to have specific content, including the first timestamp, the first encryption information, and the play address, that is, only the play request including these three pieces of information can be parsed and processed by the live broadcast server.
After the live broadcast server analyzes the broadcast request, the live broadcast server executes two authority identification processes to the broadcast request, namely, one authority identification of the broadcast request and the secondary authority identification of the broadcast request are executed, the secondary authority identification is continued only when the one authority identification is passed, if the secondary authority identification is passed, the live broadcast server sends a target video stream stored under a broadcast address to the browser, and the browser can directly play the target video stream on the browser after receiving the target video stream.
If the primary authority identification is not passed or the secondary authority identification is not passed, the live broadcast server can send a verification failure message to the browser to inform that the browser fails in the authority identification and cannot watch live broadcast, so that a user using the browser can intuitively know that the user cannot watch the live broadcast of the streaming media.
Wherein, the one-time authority identification of the playing request is completed according to the first time stamp and the acquisition time of the playing request; and the secondary authority authentication of the playing request is completed according to the first timestamp, the first encryption information and a local preset secret key.
If the live broadcast is watched without authentication, everyone knows the live broadcast address and can watch the live broadcast, which causes the waste of traffic. Therefore, by adopting the method of the embodiment, by acquiring the playing request sent by the browser, the primary authority identification and the secondary authority identification are sequentially carried out on the playing request, and under the condition that the two authority identifications are passed, the target video stream stored under the playing address is sent to the browser, so that the browser plays the target video stream.
In an embodiment, the performing authority authentication on the play request according to the first timestamp and the obtaining time of the play request may specifically include the steps of: and judging whether the time indicated by the first time stamp is after the acquisition time of the playing request.
In this embodiment, the obtaining time of the play request refers to the time when the live broadcast server receives the play request sent by the browser, and the first timestamp is compared with the obtaining time of the play request to determine whether the one-time permission authentication of the play request passes, and if the time indicated by the first timestamp is after the obtaining time of the play request, the one-time permission authentication of the play request passes, so that the secondary permission authentication of the play request can be continuously performed according to the first timestamp, the first encryption information and a local preset key; and if the time indicated by the first timestamp is before the acquisition time of the playing request, determining that the primary authority authentication of the playing request is not passed, and at the moment, performing secondary authority authentication no longer, and sending the target video stream stored in the playing address to the browser.
The time indicated by the first timestamp represents the latest usage time of the play request, and if the time indicated by the first timestamp is after the acquisition time of the play request, for example, the first timestamp is 1577085371, the conversion is carried out to the beijing time of 2019-12-2315: 16:11, and the acquisition time of the play request is 2019-12-2315: 14:10, it is obvious that the time indicated by the first timestamp is after the acquisition time of the play request, which indicates that the play request is not expired, i.e. the right of the play request passes one time authentication. And checking whether the playing request is overdue or not, if the playing request is not overdue, performing secondary authority identification on the playing request, and if the playing request is overdue, re-acquiring the playing request by the browser and re-sending the playing request to the live broadcast server. For a legal user, the live broadcast identification is sent to the conversion server, so that the playing request is obtained from the conversion server according to the live broadcast identification.
The performing of the secondary authority authentication on the play request according to the first timestamp, the first encryption information, and the local preset key specifically may include the steps of:
step S21, the first timestamp and the local preset key are processed by a preset encryption algorithm to obtain first comparison encryption information.
Step S22, determining whether the first encrypted information and the first comparison encrypted information match.
In this embodiment, after passing the one-time authorization authentication of the play request, the live broadcast server may continue to combine the first time stamp with the local preset key, and then encrypt the combined first time stamp with the local preset key by using a preset encryption algorithm to obtain first comparison encryption information, after obtaining the first comparison information, the live broadcast server may compare the first comparison information with the first encryption information carried by the play request to determine whether the first encryption information matches the first comparison encryption information, if the first encryption information matches the first comparison encryption information, it is determined that the two-time authorization authentication of the play request passes, and may send the target video stream stored at the play address to the browser, and if the first encryption information does not match the first comparison encryption information, determining that the secondary authority authentication of the playing request is not passed, and at this time, not sending the target video stream stored in the playing address to the browser, but at this time, the live broadcast server can send a prompt message that the authority authentication is not passed to the browser, so that the user knows that the authority of the user is not passed through by the browser and cannot watch the live broadcast of the streaming media.
In this embodiment, the preset encryption algorithm may be an MD5 encryption algorithm, or may be other encryption algorithms, such as a symmetric encryption algorithm or an asymmetric encryption algorithm.
Combining the first timestamp with the local preset key may be a simple combination of two parts, for example simply concatenating the two parts, illustratively the first timestamp is 1577085371, the local preset key is 6ede8f117002ae948bf78fa86f526dd4c, and the combination is 1577085371-6ede8f17002ae948bf78fa86f526dd4 c.
In the embodiment, the permission identification is firstly carried out on the play request according to the first timestamp, and the secondary permission identification is carried out under the condition that the primary permission identification is passed.
In an embodiment, considering that the live server needs to store the target video stream, the live server can send the target video stream to the browser after the browser right authentication is passed, before the step S14, the method may further include the following steps:
and step S31, acquiring a live broadcast request sent by a video source, wherein the live broadcast request carries a second timestamp, second encryption information and the live broadcast address.
Step S32, according to the second time stamp and the acquisition time of the live broadcast request, carrying out one-time authority identification on the live broadcast request;
step S33, when the primary authority authentication on the live broadcast request passes, performing secondary authority authentication on the live broadcast request according to the second encryption information of the second timestamp and the local preset key;
step S34, under the condition that the secondary authority identification of the live broadcast request is passed, a source video stream sent by the video source is obtained and stored in the live broadcast address;
and step S35, converting the source video stream into the target video stream, and storing the target video stream in the play address.
In this embodiment, the source video stream is provided by a video source, and the video source may be from live broadcast software, such as OBS, or from streaming media providing rtsp source address or rtmp source address, such as video networking streaming media developed by a certain company.
When a video source issues streaming media live broadcast, a live broadcast request can be sent to a live broadcast server, after the live broadcast server receives the live broadcast request, authority identification can be carried out on the live broadcast request firstly, if the authority identification of the live broadcast request passes, the live broadcast server can allow the video source to issue the streaming media live broadcast, and the live broadcast server can acquire a source video stream sent by the video source.
The source video stream provided by the video source is in rtsp format or rtmp format, and neither rtsp format nor rtmp format can be directly played by the browser, so that after receiving the video stream in rtsp format or rtmp format, the live broadcast server firstly stores the video stream in rtsp format or rtmp format in a live broadcast address, then converts the video stream in rtsp format or rtmp format into a format that the browser supports direct playing, namely, the video stream in m3u8 format and the video stream in websocket format, and then stores the video stream in m3u8 format and the video stream in websocket format together in the broadcast address. That is, the live address stores the source video stream, and the play address stores the target video stream.
In this embodiment, the number of users facing the live platform is large, and a plurality of browser system platforms are used, so that it is necessary to store a video stream in m3u8 format and a video stream in websocket format in the live server at the same time.
In this embodiment, the live request received by the live server also needs to have specific content, including the second timestamp, the second encryption information, and the live address, that is, only the live request including these three pieces of information can be parsed and processed by the live server.
After the live broadcast server analyzes the live broadcast request, the live broadcast request can be subjected to two authority identification processes, namely, the live broadcast request primary authority identification and the live broadcast request secondary authority identification are carried out, only under the condition that the live broadcast request primary authority identification passes through, the live broadcast request secondary authority identification can be carried out continuously, if the live broadcast request secondary authority identification also passes through, the live broadcast server can obtain a source video stream sent by a video source and store the source video stream under a live broadcast address.
If the primary authority identification is not passed or the secondary authority identification is not passed, the live broadcast server can send a verification failure message to the video source to inform that the authority identification of the video source is failed and the live broadcast cannot be issued, so that a user of the video source can intuitively know that the user cannot issue the live broadcast of the streaming media.
Wherein, one-time authority identification of the live broadcast request is completed according to a second time stamp and the acquisition time of the live broadcast request; and the secondary authority authentication of the live broadcast request is completed according to the second timestamp, the second encryption information and a local preset secret key.
In this embodiment, the specific method for identifying the primary right of the broadcast request is substantially the same as the method for identifying the primary right of the broadcast request, and is not described herein again, and the specific method for identifying the secondary right of the broadcast request is substantially the same as the method for identifying the secondary right of the broadcast request, and is not described again, which may be referred to in the foregoing embodiments specifically.
In this embodiment, a Node-Media-Server service may be utilized to convert a video stream in rtmp format or a video stream in rtsp format into a video stream in m3u8 format and a video stream in websocket format. A Node-Media-Server service is a set of scripting services written in Node.
By acquiring a live broadcast request sent by a video source, the live broadcast request is sequentially subjected to primary authority identification and secondary authority identification, under the condition that the two authority identifications are passed, receiving a source video stream sent by a video source, processing the source video stream to obtain a target video stream, then storing the target video stream in a play address, so that the live broadcast server can send the target video stream to the browser after the authentication of the play request sent by the browser is passed, by adopting the method of the embodiment, can convert the source video stream into a target video stream which is directly played by the browser, avoids the complex configuration of installing a plug-in the browser or needing the browser to support flash and the like, meanwhile, the method can prevent unauthorized video sources from being released live, prevent the live server from receiving the video stream of illegal video sources and causing the pressure of the live server to be high, and ensure the safety of the live streaming of the streaming media.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of another live streaming media playing method according to an embodiment of the present invention, where the method is applied to a conversion server, and the method specifically includes the following steps:
and step S41, acquiring the live broadcast identification sent by the browser.
Step S42, determining a playing address according to the live broadcast identification;
step S43, determining a first standard timestamp according to the acquisition time of the live broadcast identification and a preset time interval;
step S44, determining first standard encryption information according to the first standard timestamp, a local preset secret key and a preset encryption algorithm;
step S45, generating a playing request according to the playing address, the first standard timestamp and the first standard encryption information;
step S46, sending the play request to the browser, so that the browser obtains the target video stream stored at the play address from a live broadcast server according to the play request, thereby playing the live broadcast of the streaming media corresponding to the target video stream.
In this embodiment, the play request of the legal user is generated by the conversion server and sent to the browser, so that, for the live broadcast process of the streaming media of the legal user, before the browser sends the play request to the live broadcast server, the browser needs to obtain the play request from the conversion server.
When a legal user wants to watch the live broadcast of the streaming media in a browser, the legal user needs to know the live broadcast identification of the watched live broadcast of the streaming media, the live broadcast identification can be a live broadcast ID or a live broadcast room number, after the user inputs the live broadcast identification into the browser, the browser sends the live broadcast identification to a conversion server, after the conversion server receives the live broadcast identification sent by the browser, the conversion server calls an interface of the conversion server according to the live broadcast identification to obtain a playing address corresponding to the live broadcast identification, and meanwhile, a first standard timestamp and first standard encryption information are generated, and finally, a playing request is generated according to the playing address, the first standard timestamp and the first standard encryption information.
Specifically, the conversion server adds the acquisition time of the live broadcast identifier to a preset time interval to generate a first standard timestamp. The preset time interval refers to how much time the play request is allowed to be used after acquiring the live identification. The first standard timestamp is generated by the conversion server, and the preset time interval refers to how much time the play request is allowed to be used after the live broadcast identifier is acquired, so the first standard timestamp is used for indicating the latest use time of the play request, and the time for using the play request exceeds the time indicated by the first standard timestamp, so the play request is invalid, that is, the live broadcast server does not pass the authentication of the play request once.
After the first standard timestamp is obtained, the first standard encryption information can be determined according to the first standard timestamp, the local preset secret key and the preset encryption algorithm. Specifically, the first standard timestamp and the local preset key are combined, and then the combined first standard timestamp and the local preset key are encrypted by using a preset encryption algorithm to obtain first standard encryption information.
The preset encryption algorithm may be an MD5 encryption algorithm, or may be other encryption algorithms, such as a symmetric encryption algorithm or an asymmetric encryption algorithm. In this embodiment, it needs to be ensured that the preset encryption algorithms used by the conversion server and the live broadcast server are the same, and the local preset keys in the conversion server and the live broadcast server are also the same, for example, the preset encryption algorithms used by the conversion server and the live broadcast server are both MD5 encryption algorithms, and the local preset keys in the conversion server and the live broadcast server are both 7ede812ca002ae948bf78fa86f526dd4 d.
Combining the first standard timestamp with the local preset key may be a simple combination of two parts, for example simply concatenating the two parts, illustratively the first timestamp is 1577085075 and the local preset key is 7ede812ca002ae948bf78fa86f526dd4d combined to 15770850757-ede812ca002ae948bf78fa86f526dd4 d.
After the playing address, the first standard timestamp and the first standard encryption information are respectively obtained, the conversion server may generate a playing request, that is, the playing request may be composed of the playing address, the first standard timestamp and the first standard encryption information.
Illustratively, the browser receives a play request, sends the play request to the live broadcast server, and if the play request is generated by the conversion server and the time indicated by the first timestamp in the play request is after the acquisition time of the live broadcast server for the play request, the browser may acquire the stored target video stream at the play address from the live broadcast server, thereby playing the streaming media corresponding to the target video stream.
In an implementation manner, the conversion server may further obtain a live broadcast address sent by a video source, and determine a second standard timestamp according to the obtaining time of the live broadcast address and a preset time interval; determining second standard encryption information according to the second standard timestamp and a preset encryption algorithm; generating a live broadcast request according to the live broadcast address, the second standard timestamp and the second standard encryption information; and sending the live broadcast request to the video source so that the video source sends a source video stream to the live broadcast server according to the live broadcast request, and the live broadcast server converts the source video stream into a target video stream and stores the target video stream in the play address.
In this embodiment, the second standard timestamp is used to indicate the latest usage time of the live broadcast request, and the time of using the play request exceeds the time indicated by the second standard timestamp, so that the live broadcast request fails, that is, the live broadcast server does not pass the authentication of the live broadcast request once.
In this embodiment, the generation method of the second standard timestamp is similar to that of the first standard timestamp, and is not described herein again, the generation method of the second standard encrypted information is similar to that of the first standard encrypted information, and is not described herein again, and the generation method of the live broadcast request is similar to that of the play request, and is not described herein again.
