All the above alternatives, can form the alternative embodiment of the application according to any combination, and the application is real It applies example and this is no longer repeated one by one.
Fig. 3 is a kind of method for pushing flow chart of the live video stream shown according to another exemplary embodiment, this implementation Example is applied to be illustrated in implementation environment shown in above-mentioned Fig. 1 with the method for pushing of the live video stream, and this method can be with Including following several realization steps:
Step 301: during the push of live video stream, when the live video stream of push is double screen stream, monitoring is straight Broadcast the transmission performance indicators of video flowing.
As it was noted above, main broadcaster's terminal can carry out coded treatment to two-way live video stream respectively, later while backward Two-way live video stream after platform server push coded treatment, wherein the two-way live video stream includes transverse screen stream and vertical screen Stream is properly termed as push double screen stream here.During pushing double screen stream, for the ease of can when unstable networks To be adjusted automatically to push mode, the transmission performance indicators of main broadcaster's terminal monitoring live video stream.
In one possible implementation, which may include that video encoding rate and/or video frame are lost Packet rate.It that is to say, main broadcaster's terminal can monitor video encoding rate, alternatively, video frame packet loss can also be monitored, then alternatively, also Video encoding rate and video frame packet loss can be monitored simultaneously.
Further, before executing method provided by the embodiments of the present application, it can show that plug-flow adjusts function choosing-item, it should For opening or closing plug-flow mode adjustment function, which refers to straight according to this plug-flow adjustment function choosing-item The push state adjustment plug-flow mode for broadcasting video flowing is executed when detecting that plug-flow adjustment function choosing-item is in the open state The method for pushing of live video stream provided by the embodiments of the present application.
For example, main broadcaster's terminal can show that plug-flow adjusts function choosing-item on live streaming interface, when main broadcaster user wants main broadcaster When terminal can be according to the push situation adjust automatically plug-flow mode of live video stream, plug-flow adjustment function choosing-item can control It is in the open state, to open plug-flow mode adjustment function, in this way, main broadcaster's terminal will monitor directly automatically during live streaming Broadcast the transmission performance indicators of video flowing.
Further, plug-flow adjustment function choosing-item defaults open state, or can also be manually opened by main broadcaster user. In addition, also can control plug-flow adjustment function choosing-item when main broadcaster user does not need main broadcaster's terminal adjust automatically plug-flow mode It is in close state, the plug-flow mode adjustment function can also close therewith at this time.Further, when the plug-flow mode adjustment function After capable of closing, main broadcaster's terminal resets historical statistical data, which includes but is not limited to the reference live streaming of history Number, with reference to live streaming duration, continuous Caton degradation numerical value.
Step 302: when the transmission performance indicators are less than reference index threshold value, the push of double screen stream being reduced to single screen stream and is pushed away It send, and the continuous Caton degradation numerical value is increased by the first numerical value.
Wherein, the continuous Caton degradation numerical value be used for indicate continuously from double screen stream push be reduced to single screen stream push number or Degradation rate.
In an implementation, when causing the push of live video stream Caton phenomenon occur since network transmission performance is poor When, the push of adjust automatically live video stream can be generally carried out by adjusting modes such as encoding rates, however, when live video stream When transmission performance indicators are still less than reference index threshold value, illustrate that live video still can not be solved by adjusting modes such as encoding rates Double screen stream can be pushed be reduced to the push of single screen stream at this time by the push Caton problem of stream, also, main broadcaster's terminal is by the continuous Caton Degradation numerical value increases by the first numerical value.
Wherein, which can be by user's customized setting according to actual needs, can also be by main broadcaster end Default setting is held, the embodiment of the present application is not construed as limiting this.
In addition, first numerical value can also be write from memory by user's customized setting according to actual needs by main broadcaster's terminal Recognize setting.For example, which can be set to 1, and the continuous Caton degradation numerical value is increased by 1 when counting every time at this time.
In one possible implementation, may include: by the realization that the push of double screen stream is reduced to the push of single screen stream will be horizontal Screen stream is sent to background server, and forbids pushing vertical screen stream.That is, the push of double screen stream is reduced to the push of single screen stream When, vertical screen stream can be cut off, only push transverse screen stream to background server.
Certainly, above-mentioned said for stopping push vertical screen stream when the push of double screen stream is reduced to the push of single screen stream It is bright, in another embodiment, it can also stop pushing transverse screen stream, the embodiment of the present application does not limit this.
It should be noted that after the push of double screen stream is reduced to the push of single screen stream by main broadcaster's terminal, in some embodiments, when Detect situations such as increasing new business, for example when the company of increasing wheat business, main broadcaster's terminal can restart double screen stream and push away It send.Later, main broadcaster's terminal continues to monitor the transmission performance indicators of live video stream during double screen stream pushes, to count continuous card Pause degradation numerical value.
In addition, it is necessary to explanation, above-mentioned steps 301 and step 302 are for realizing in the push process of live video stream In, count the operation of continuous Caton degradation numerical value.
Step 303: being broadcast live in number or reference live streaming duration when in reference, which reaches with reference to drop When grade threshold value, start continuous single screen stream mode, which refers to the mode for only allowing to push single screen stream.
Wherein, reference live streaming number and reference live streaming duration can be set by user is customized according to actual needs It sets, this can also be not construed as limiting by main broadcaster's terminal default setting, the embodiment of the present application.
Wherein, this can be by user's customized setting according to actual needs with reference to degradation threshold value, can also be by main broadcaster end Default setting is held, the embodiment of the present application is not construed as limiting this.
When the continuous Caton degradation numerical value reaches with reference to degradation threshold value in reference main broadcaster number or reference live streaming duration, Illustrate that continuous several times detect Caton collapse event, i.e. continuous several times main broadcaster terminal is reduced to list because Caton situation pushes double screen stream Screen stream push, starts continuous single screen stream mode at this time, does not allow to push two-way live video stream simultaneously in this kind of mode, only allow Push live video stream all the way.
Such as, it is assumed that the continuous Caton degradation numerical value is used to indicate continuously to be reduced to time that single screen stream pushes from the push of double screen stream Number, this is 10 times with reference to live streaming number, when this is set as 5 with reference to degradation threshold value, if detected in 10 live streamings at this Continuous Caton degradation numerical value reaches 5 times, then starts continuous single screen stream mode, i.e., only single screen stream is allowed to push.For another example, it is assumed that the company Continuous Caton degradation numerical value is used to indicate continuously to be reduced to the degradation rate that single screen stream pushes from the push of double screen stream, a length of when this is with reference to live streaming 300 minutes, when this is set as 20% with reference to degradation threshold value, if continuous Caton drop was detected in live streaming duration at 300 minutes Grade rate reaches 20%, then starts continuous single screen stream mode, i.e., only single screen stream is allowed to push.
It should be noted that during counting continuous Caton degradation numerical value, if number is broadcast live in reference or with reference to straight In sowing time is long, which not up to refers to degradation threshold value, then resets the continuous Caton degradation numerical value again It is counted.
Step 304: whether the push state for monitoring live video stream meets double screen stream pushing condition.
During main broadcaster's terminal executes the push of single screen stream, in order to determine when to revert in the case of which kind of Whether the push of double screen stream, the push state that can monitor live video stream meet double screen stream pushing condition.In a kind of possible reality In existing mode, it may include as follows that whether the push state for monitoring live video stream, which meets the specific implementation of double screen stream pushing condition, Two kinds of possible situations:
The first situation: statistics single screen flow/time length, the single screen flow/time length refer to the duration of the continuous single screen stream mode, When the single screen flow/time length reaches the first duration threshold value, determine that the push state of the live video stream meets double screen stream push item Part.
Wherein, which can be by user's customized setting according to actual needs, can also be by main broadcaster end Default setting is held, the embodiment of the present application is not construed as limiting this.
That is to say, main broadcaster's terminal counts the duration of continuous single screen stream mode, if the duration reach this first Duration threshold value, it may be considered that the push environment restoration of live video stream can determine the live video to stable state at this time The push state of stream meets the double screen stream pushing condition.Wherein, stable state described in the embodiment of the present application refers to push environment It can satisfy the state of double screen stream push.
For example, it is assumed that the first duration threshold value is 12 hours, then main broadcaster's terminal starts after entering continuous single screen stream mode The duration of the continuous single screen stream mode is counted, once detecting that the duration reaches 12 hours, then can determine that this is straight The push state for broadcasting video flowing meets the double screen stream pushing condition.
Second situation: statistics single screen stablizes push times and/or the interim push times of single screen, which stablizes push time Number refers to, and the number that Caton is broken does not occur during the duration of single screen stream push is more than the second duration threshold value and plug-flow, which faces When push times refer to single screen stream push duration be not up to the second duration threshold value and plug-flow during do not occur what Caton was broken Number；When the single screen stablizes push times and/or the interim push times of the single screen reach the first frequency threshold value, the live streaming is determined The push state of video flowing meets the double screen stream pushing condition.
Wherein, which can be by user's customized setting according to actual needs, can also be by main broadcaster end Default setting is held, the embodiment of the present application is not construed as limiting this.
In addition, first frequency threshold value can be by user's customized setting according to actual needs, it can also be by main broadcaster end Default setting is held, the embodiment of the present application is not construed as limiting this.
In one possible implementation, main broadcaster's terminal statistics single screen stablizes push times.Specifically, if single screen stream Pushing duration is more than the second duration threshold value, and there is no Caton collapse event in duration, then main broadcaster's terminal Single screen is stablized into push times and increases second value.When single screen, which stablizes push times, reaches the first frequency threshold value, it is believed that The push environment of live video stream is substantially more stable, can determine that the push state of the live video stream meets the double screen at this time Flow pushing condition.

In an implementation, starting double screen stream push, statistics double screen stablizes push times during the push of double screen stream, i.e. statistics double screen stream pushes away The number of Caton degradation does not occur during being more than third duration threshold value and plug-flow for the duration sent.If the double screen stablizes push times Reach the second frequency threshold value, illustrates that Caton collapse event does not occur during the push of double screen stream, at this time it is considered that live video The push environment of stream, which determines, to be restored to stable state, thus may determine that the push state of the live video stream meets the double screen stream Pushing condition., whereas if Caton number, which occurs, in period reaches setting value, then illustrate the push environment of live video stream and non-real It is positive to restore to stable state, need to come back to the operation for starting continuous single screen stream mode at this time, main broadcaster's terminal is by historical data It resets and restarts to calculate.
Wherein, which can be by user's customized setting according to actual needs, can also be by main broadcaster end Hold default setting.In some embodiments, which can be identical as the second duration threshold value, certainly, the third Duration threshold value can also be different from the second duration threshold value, and the embodiment of the present application does not limit this.
Wherein, which can be by user's customized setting according to actual needs, can also be by main broadcaster end Default setting is held, the embodiment of the present application is not construed as limiting this.
