[0032] Optionally, as an optional implementation, as Figure 2 As shown, the method for transmitting the live stream may be performed by an electronic device, which may be, for example, Figure 1 The user device or server shown in the figure comprises:

[0033] S202, obtaining a multi-source live stream, wherein the multi-source live stream is a live stream formed by converging at least two live streams, and the at least two live streams are audio and video streams from different live sources but showing the same live content;

[0034] S204, determining a target live stream from the at least two live streams according to the transmission quality of the live streams in the at least two live streams;

[0035] S206, transmitting the target live stream to a target push address, wherein the target push address is a push address to which at least two live streams belong.

[0036] Optionally, in this embodiment, a multi-source live stream can be obtained by acquiring at least two live streams at the access point of the live stream, and then aggregating the at least two live streams into one multi-source live stream for transmission of the aggregated live stream.

[0037] Optionally, in this embodiment, a live stream formed by the convergence of at least two live streams can be converged in a manner that each live stream is converged into a multi-track video stream, and each track is used to transmit the audio and video of the live stream; the convergence method can also be that each live stream is converged into a multi-track video stream, and each track is used to transmit a specific signal, such as a video signal, an audio signal, a text signal, etc.

[0038] Optionally, in this embodiment, at least two live streams may be audio and video streams from different live sources but showing the same live content. For example, in the same live broadcast, live streams acquired by audio and video capture devices broadcasting the same content but at different positions.

[0039] Optionally, in this embodiment, the streaming address of at least two live streams belonging to the same channel can be an address to which at least two live streams are pushed together. For example, when a user uses a mobile terminal to issue a request to obtain a certain live content, the streaming address of at least two live streams belonging to the same channel is the mobile terminal used by the user.

[0040] As an optional scheme, a target live stream is determined from at least two live streams according to the transmission quality of the live streams in the at least two live streams, including: determining the target live stream from the at least two live streams according to the signal transmission quality of each track, wherein the track is a track formed by converging multiple tracks associated with any live stream of the at least two live streams, and the track is used to transmit audio and video signals of the same live stream.

[0041] Optionally, in this embodiment, the audio and video signals of the same live stream may include all signals in the original live stream, such as: video signal, audio signal, text signal, etc.

[0042] To further illustrate, when a user sends a request to obtain a certain live broadcast content through a mobile terminal, there are at least two audio and video acquisition devices for the live broadcast content, and one audio and video acquisition device can generate one live broadcast stream, and ultimately at least two live broadcast streams will be generated. After the at least two live broadcast streams are aggregated into one multi-source live broadcast stream, the at least two tracks of the aggregated multi-source live broadcast stream are used to transmit the original at least two live streams, and the audio and video signals that are finally pushed to the user's mobile terminal are selected based on the quality of the tracks transmitting the at least two live broadcast streams.

[0043] It should be noted that after obtaining a multi-source live stream formed by the convergence of at least two live streams, it is necessary to confirm the transmission quality of the at least two live streams, determine the target live stream based on the transmission quality of the live streams, and push the target live stream to the streaming address to which the at least two live streams belong.

[0044] To further illustrate, the optional Figure 3 As shown, a multi-source live stream 302 is obtained, wherein the multi-source live stream is a live stream formed by the convergence of at least two live streams, and the at least two live streams are audio and video streams from different live sources but showing the same live content; according to the transmission quality of the live streams in the at least two live streams, a target live stream (live stream B) is determined from the at least two live streams; the target live stream is transmitted to a target push address 304, wherein the target push address is a push address to which at least two live streams belong.

[0045] Through the solution provided in the embodiment of the present application, the purpose of giving priority to the transmission of live streams with better quality is achieved, and the need to switch other live streams for transmission during the transmission of live streams due to transmission quality is reduced, thereby reducing the negative impact on the transmission of live streams caused by switching live streams, thereby achieving the technical effect of improving the transmission efficiency of live streams, and further solving the technical problem of low transmission efficiency of live streams.

[0046] As an optional scheme, the target live stream is determined from at least two live streams according to the signal transmission quality of the track, including: determining the target live stream from the at least two live streams according to the signal transmission quality of each first-class track, wherein the first-class track is N tracks formed by aggregating multiple tracks associated with the at least two live streams according to the same type, the first-class track is used to transmit the same type of audio and video signals, and the number of types of the multiple tracks is N.

[0047] Optionally, in this embodiment, the audio and video signals may be different signal components of a live stream, such as a video signal, an audio signal, a text signal, etc., and each signal of each live stream has a live stream mark to mark which live stream the signal belongs to.

[0048] To further illustrate, when a user sends a request to obtain a certain live content through a mobile terminal, there are at least two audio and video acquisition devices for the live content, and one audio and video acquisition device can generate one live stream, and ultimately at least two live streams will be generated, and each live stream has multiple signals, and the multiple signals of at least two live streams are gathered together by type, and the signals are pushed through tracks, for example, track A is used to push video signals, track B is used to push audio signals, and track C is used to push text signals.

[0049] Through the solution provided by the embodiment of the present application, when receiving multiple live streaming signals, the audio and video of the live streaming are separated and aggregated according to type, and the aggregated tracks are transmitted through tracks, thereby improving the transmission efficiency of the live streaming.

[0050] As an optional solution, before determining a target stream from at least two live streams based on the signal transmission quality of the track, where the track is used to transmit the audio and video signals of the audio and video stream, the method also includes: determining the track described by each audio and video signal according to the pre-configured tags of each audio and video stream signal.

[0051] Optionally, in this embodiment, the preconfigured mark may be a mark indicating which track all audio and video signals corresponding to an original live stream are transmitted by, or a mark indicating which track a certain type of audio and video signal is transmitted by.

[0052] Through the solution provided by the embodiment of the present application, after the audio and video signals corresponding to the live stream are obtained, the obtained audio and video signals are marked, and then the audio and video signals are transmitted through the tracks corresponding to the marks, thereby achieving correct transmission of new video signals.

[0053] As an optional solution, before determining a target live stream from at least two live streams based on the transmission quality of the live streams in at least two live streams, the method also includes: determining the transmission quality of the live stream based on the freeze or interruption duration of the at least two live streams.

[0054] Optionally, in this embodiment, the freeze or interruption duration of the two live streams may be a single freeze or interruption duration or a cumulative freeze or interruption duration generated during the transmission of the audio and video signals corresponding to the live streams.

[0055] To further illustrate, when track A is used to transmit all audio and video signals corresponding to live stream a, the duration of freeze or interruption in the stream is shorter than that when track B is used to transmit all audio and video signals corresponding to live stream b, then the transmission quality of live stream a is considered to be better than that of live stream b.

[0056] Through the solution provided in this embodiment, the transmission quality of the live stream is determined by the duration of freezing or interruption, thereby improving the efficiency of transmitting the live stream.

[0057] As an optional solution, after determining the transmission quality of the live stream according to the freeze or interruption duration of at least two live streams, the method further includes:

[0058] S1-1, determining a first live stream from at least two live streams according to a queue preset for at least two live streams;

[0059] S1-2, when the freeze or interruption duration of the first live stream is less than or equal to a preset threshold, determining the first live stream as the target live stream;

[0060] S1-3, when the freeze or interruption duration of the first live stream is greater than a preset threshold, determining a second live stream after the first live stream from at least two live streams;

[0061] S1-4, when the freeze or interruption duration of the second live stream is less than or equal to a preset threshold, the second live stream is determined as the target live stream.

[0062] Optionally, in this embodiment, according to the queues preset for the at least two live streams, the first live stream is determined from the at least two live streams. The live stream at the front of the queue can be determined as the first live stream according to the queues preset for the two live streams. The queues preset for the two live streams can be a queue in which the live streams are arranged in the order in which they start transmission, or can also be a manually determined queue.

[0063] Optionally, in this embodiment, the duration of the freeze or interruption is less than or equal to the preset threshold, which means that the duration of a single freeze or interruption is less than or equal to a first preset threshold and the cumulative duration of the freeze or interruption is less than or equal to a second preset threshold.

[0064] Optionally, in this embodiment, when the duration of freeze or interruption of the first live stream is less than or equal to a preset threshold, the first live stream can be determined as the target live stream and transmitted through the track.

[0065] Optionally, in this embodiment, when the duration of freeze or interruption of the first live stream is greater than a preset threshold, a second live stream after the first live stream is determined from at least two live streams, and when the duration of freeze or interruption of the first live stream is greater than the preset threshold, the backup signal is set to the second live stream.

[0066] Optionally, when the cumulative freeze or interruption duration of the second live stream is less than or equal to a preset threshold, the second live stream is determined as the target live stream. Alternatively, when the target live stream is the first live stream, and the freeze or interruption duration is greater than the preset threshold, and the single freeze or interruption duration of the second live stream is less than or equal to the preset threshold, the target live stream is switched to the second live stream, and the cumulative freeze or interruption duration of the first live stream is cleared.

[0067] Optionally, the target live stream may be specified through a manually specified mode.

[0068] It should be noted that if there are at least three live streams that converge into one multi-source live stream, the switching queue of the target live stream is a ring queue.

[0069] To further illustrate, when the target live stream is the first live stream, the target live stream switching is triggered, and the target live stream is switched to the second live stream; when the target live stream is the second live stream, the target live stream switching is triggered, and the target live stream is switched to the third live stream; when the target live stream is the third live stream, the target live stream switching is triggered, and the target live stream is switched to the first live stream.

[0070] Through the solution provided in this embodiment, by timely switching the target live stream, it is possible to switch in time when a long freeze occurs, and the effect of timely solving the live freeze after the live freeze occurs is achieved.

[0071] It should be noted that after obtaining a multi-source live stream formed by the convergence of at least two live streams, it is necessary to confirm the transmission quality of the at least two live streams, determine the target live stream based on the transmission quality of the live streams, and push the target live stream to the streaming address to which the at least two live streams belong.

[0072] To further illustrate, the optional Figure 3 As shown, a multi-source live stream 302 is obtained, wherein the multi-source live stream is a live stream formed by the convergence of at least two live streams, and the at least two live streams are audio and video streams from different live sources but showing the same live content; according to the transmission quality of the live streams in the at least two live streams, a target live stream (live stream B) is determined from the at least two live streams; the target live stream is transmitted to a target push address 304, wherein the target push address is a push address to which at least two live streams belong.

[0073] Through the solution provided in the embodiment of the present application, the purpose of giving priority to the transmission of live streams with better quality is achieved, and the need to switch other live streams for transmission during the transmission of live streams due to transmission quality is reduced, thereby reducing the negative impact on the transmission of live streams caused by switching live streams, thereby achieving the technical effect of improving the transmission efficiency of live streams, and further solving the technical problem of low transmission efficiency of live streams.

[0074] As an optional solution, for ease of understanding, the above live streaming transmission method is applied to a live video broadcast scenario as an example:

[0075] In the existing live streaming transmission, if there are multiple different audio and video acquisition devices, for example, when there are multiple cameras in the same live broadcast, one camera corresponds to one live stream, but the status of each stream needs to be detected and controlled in real time. If the signal quality or availability of the currently transmitted live stream is abnormal, the algorithm for implementing disaster recovery switching control is complex and prone to errors.

[0076] Optionally, in this embodiment, the transmission of the live stream can be, but is not limited to, converging multiple live streams corresponding to multiple cameras of the same live broadcast into a multi-track live stream at the streaming boarding point, and marking the correspondence between the multiple live streams and each track in the multi-track live stream. After the multi-track live stream is transmitted to the central source station, the central source station associates the multi-track stream with a certain track filter. When it is detected that the transmission of the live stream corresponding to a certain track triggers the switching track condition of the track filter, the track is switched from the track transmitting the live stream to the track transmitting the next live stream, and the live stream transmission of the next live stream is performed.

[0077] Optionally, in this embodiment, the track filter is used to set preset values ​​for freeze and interruption durations, and is also used to detect track quality and availability.

[0078] To further illustrate, the optional Figure 4 As shown, the specific steps are as follows:

[0079] S402, the edge node sends a request for obtaining live content;

[0080] It should be noted that the live content acquisition request sent by the edge node includes: the live content acquisition request sent by the user when using the terminal or device.

[0081] S404, in response to the live content acquisition request, acquiring multiple live streams corresponding to the live content;

[0082] S406, aggregating multiple live streams into one multi-track live stream at the streaming loading point;

[0083] S408, transmitting a multi-track stream to a central source station;

[0084] S410, setting a track filter for a multi-track stream at a central source station;

[0085] S412, determining a main signal live stream and a backup signal live stream according to the track quality of one multi-track stream obtained by the track filter;

[0086] S414, the track filter determines the target live stream as the main signal live stream;

[0087] S416, if the duration of freezing or interruption of the target live stream is less than or equal to the target threshold, execute step S418, otherwise execute S420;

[0088] S418, transmitting the target live stream from the central source station to the regional central node;

[0089] S420, confirming the target live stream as the next live stream according to the order of the ring queue, and returning to S416;

[0090] S422, transmit the target live stream to the edge node.

[0091] Through the solution provided in the embodiment of the present application, multiple live streams showing the same content are aggregated into one multi-track live stream, and if an abnormality occurs in the current live stream during the live broadcast, it is only necessary to switch the track of the same channel to switch other live streams without switching other channels, thereby achieving the purpose of signal transmission of multiple live streams through one multi-track live stream, thereby achieving the technical effect of easily monitoring the transmission quality of the live stream and switching the live stream.
