As shown in Figure 1, a kind of flow of the generation method of live video summary provided in an embodiment of the present invention, can wrap It includes：
S101, since live streaming, every the period of the first duration, the live streaming segment of the first duration of acquisition.
It is broadcast live, just live streaming is sampled every the period of the first duration, collect a sampling since main broadcaster Segment is the live streaming segment of the first duration, which can be pre-set time span.It thereby realizes pair The segmentation of main broadcaster's live streaming, convenient for subsequently extracting the live content for best embodying main broadcaster's style and characteristic.
S102 obtains the number of users for the live streaming segment for watching each first duration and the message number of user's transmission, will The number of users and message number of acquisition input default excellent degree calculation formula, calculate the live streaming segment of each first duration Excellent degree.
In general, the live content for best embodying main broadcaster's style and characteristic is exactly the splendid contents being broadcast live, when being broadcast live out During existing splendid contents, watch the message number that the spectators of this section of splendid contents send that can increase.When therefore, for each first Long live streaming segment can obtain the message number of the number of users for watching the live streaming segment and user's transmission, by the use of acquisition Amount amount and message number input default excellent degree calculation formula, calculate the excellent journey of the live streaming segment of each first duration Degree.The excellent degree enables the different splendid contents of different live streaming segments to be compared with unified standard, convenient for follow-up Extraction best embodies the live content of main broadcaster's style and characteristic from the live streaming segment of each first duration.Wherein, excellent degree Calculation formula i.e. excellent degree and number of users and the mathematical operation relation of message number.
S103, according to the excellent degree of the live streaming segment of each first duration, from the straight of each first duration It broadcasts in segment, chooses the first excellent highest live streaming segment of degree of default quantity, obtain excellent live streaming segment.
The excellent live streaming segment is synthesized live video summary, and is illustrated in the live streaming boundary of corresponding main broadcaster by S104 In face.
Live streaming segment contents are more excellent, and the excellent degree of the segment is higher.Therefore from the live streaming of each first duration In segment, the first excellent highest live streaming segment of degree of default quantity is chosen, these live streaming segments can be used as excellent live streaming piece Section synthesizes live video summary.Such as：From 60 live streaming segments of 1 minute of acquisition, 5 excellent degree highests are chosen Live streaming segment, this 5 live streaming segments excellent degree be followed successively by 10,9,8,7,6, be above it is remaining 55 live streaming segment, This 5 live streaming segments are then synthesized into live video summary, and are illustrated in the live streaming interface of corresponding main broadcaster.
The method of above-described embodiment, while multiple excellent live contents are extracted, by these excellent live streaming segments certainly Dynamic circuit connector is made a summary as live video, and is illustrated in the direct broadcasting room interface of corresponding main broadcaster.When user wants to know about a certain main broadcaster, As long as watch the live video summary in main broadcaster's direct broadcasting room interface, it is possible to watch the main broadcaster in a short time and repeatedly be broadcast live In essential part, avoiding user in conventional method needs to take a significant amount of time the whole field live streaming of repeatedly viewing main broadcaster or go through The problem of history plays back understands the style and characteristic of main broadcaster with making user's more convenient and quicker.
Optionally, the step S101 of embodiment illustrated in fig. 1, can specifically include：
The live streaming segment of the first duration is obtained by continuous sampling；The continuous sampling is, first duration when Between when two adjacent live streaming segments is obtained in section, time interval 0.
Such as：First duration is arranged to 1 minute, the live streaming time started is 14:When 00, first is obtained by continuous sampling The process of the live streaming segment of duration is：14:01 acquisition 14:00-14:01 live streaming segment A, 14:02 acquisition 14:01-14:02 Segment B is broadcast live, 14:01 to 14:In 1 minute of 02, the time interval between adjacent two live streaming segments A, B is 0.Pass through The mode of continuous sampling can ensure that the live streaming segment of the first duration obtained is to contain the live streaming piece of all splendid contents Section, avoids omitting any splendid contents.
Give up the final stage live streaming segment obtained when live streaming stops every time.
In general, be broadcast live stop when obtaining final stage sampling segment duration be less than before sample segment when It is long, and main broadcaster in the period before stopping is broadcast live and does not have brilliant show, therefore can will be obtained most when live streaming stops every time Latter section of live streaming segment is cast out.Which reduces poor redundancies to be broadcast live segment, is conducive to improve live video summary life Into efficiency, and the method for sampling of the identical duration for the present embodiment, it is ensured that the isometric property of live streaming segment.
Optionally, the step S102 of embodiment illustrated in fig. 1, can specifically include：
At the end of the live streaming segment for obtaining each first duration, the live streaming segment of each first duration is watched Number of users.
Due to during each live streaming, there is a situation where that certain customers' not timing enters or leaves direct broadcasting room, together Shi Ruguo live contents are excellent enough, and user will be attracted to stay in direct broadcasting room and continue to watch, therefore for each first duration Segment is broadcast live, unification is using the number of users of direct broadcasting room at the end of the live streaming segment as the number of users for watching the live streaming segment.
Such as：A length of 1 minute when first, the live streaming of certain main broadcaster is from 14:00 starts, and a live streaming segment A of acquisition is 14: 00 to 14:During 01 live content, at the end of obtaining live streaming segment A, that is, 14:The number of users of main broadcaster's direct broadcasting room when 01 Amount, it is to be appreciated that the user of direct broadcasting room is exactly the user of viewing live streaming.It is seen in period with directly acquiring the first duration See that the number of users of the live streaming segment of each first duration is compared, this method eliminates inactive users quantity, after being conducive to The continuous excellent degree for obtaining the more accurately live streaming segment of each first duration.
It obtains in first duration, the message count corresponding with the live streaming segment of each first duration that user sends Amount.
It is understood that user has sent message and just represents to live content " cheer " in live streaming, that is to say, that one As in the case of have sent the user of message and will not leave live streaming, can be direct therefore when obtaining the message number that user sends Obtain the message number corresponding to the live streaming segment that user sends in first time period.Such as：A length of 1 minute when first, The live streaming of certain main broadcaster is from 14:00 starts, and a live streaming segment A of acquisition is 14:00 to 14:During 01 live content, 14 are obtained:00 To 14:The message number that user sends in 01 period.
After obtaining number of users and message number using above-mentioned optional mode, the default excellent degree calculates public Formula can be：
Wherein, t is first duration, and p is the number of users, and m is the message number, and w is first duration Live streaming segment excellent degree.
It is understood that the accuracy for the excellent degree that the setting of t need to can guarantee, t, which crosses conference, causes what is obtained Be broadcast live segment it is long and comprising more redundancy, the excellent degree of the segment for making acquisition is not accurate enough, and t is too small to increase calculating It measures and reduces efficiency, and since the too small contingency that excellent degree can be caused to calculate of live video segmentation is higher.Therefore, Ke Yigen T is set according to historical experience, alternatively, setting t according to the current transmission rate of live video when obtaining live streaming segment.Such as：The value of t It could be provided as 10 seconds, alternatively, more than 10 seconds.
T is set according to historical experience.Can be that a large amount of live videos are sampled with different t by analyzing to compare in advance When, whether obtained excellent degree is corresponding with the excellent situation of reality of each live streaming segment contents, so that it is determined that going out one properly Value.Such as：When t is 10 seconds, the excellent degree value of obtained each live streaming segment, the reality with each live streaming segment contents Excellent situation is corresponding, then can be arranged to t 10 seconds.
Alternatively, t is set according to the transmission rate of live video when obtaining live streaming segment.Since live streaming is that one kind regards in real time Frequency spreads transferring technology, and transmission rate changes due to the transmission environment in transmission process influences, the transmission rate when transmission environment is good Soon, the live video stream transmitted within a certain period of time is more, and transmission rate is slow when transmission environment is poor, transmits within a certain period of time Live video stream it is few.Such as：When transmission rate is fast, the live content transmitted in 10 seconds has been finished in short for main broadcaster, and is passed When defeated rate is slow, the live content transmitted in 10 seconds does not finish the words also for main broadcaster.Therefore, can be set according to historical experience T on the basis of, according to the current transmission rate of live video, adaptability sets t.Can specifically it include：Live streaming is obtained every time Before segment, the current transmission rate of live video is first obtained, compares current transmission rate and default rate-valve value.It is if current Transmission rate is more than or equal to default rate-valve value, then every the period of the first duration, the live streaming segment of the first duration of acquisition； If current transmission rate is less than default rate-valve value, every the period of the 5th duration, the live streaming of the 5th duration is obtained Segment；Wherein, the 5th duration is more than first duration.Such as：Before the live streaming segment for obtaining t durations, live streaming is first obtained The current transmission rate v of video compares v and default rate-valve value v0Size, wherein default rate-valve value v0According to go through The live video average transmission rate that history experience is set.If v >=v0, then t is arranged to historical experience value 10 seconds, if v<v0, So t may be configured as 12 seconds.It is appreciated that in v<v0In the case of, appropriate the first duration t for increasing sampling can be to avoid The delay of the live streaming segment contents obtained caused by live video transmission rate is relatively slow, can make acquisition the first duration it is straight The excellent degree for broadcasting segment is more accurate.Specific setting for the first duration t can also be other any modes, every energy Enough make the set-up mode of the sufficiently exact t of excellent degree of the live streaming segment of the first duration of acquisition, may be incorporated for the present invention, The present embodiment is not restricted this.
Since the excellent degree acquisition methods are to characterize first with the message number of unit user transmission in the unit interval The excellent degree of the live streaming segment of duration, therefore, either piece is broadcast live according to acquisition in the t whether set according to historical experience The t that the current transmission rate adaptability of live video is set during section, that is, any mode to live video segmentation, can lead to Cross the excellent degree of the quantization of the live streaming segment of a length of t when this method obtains.
Optionally, the step S103 of embodiment illustrated in fig. 1, can specifically include：
From the live streaming segment of each first duration, the first excellent highest live streaming of degree of default quantity is selected Segment, as pending live streaming segment；Each supplement segment for increasing by the second duration at each pending live streaming segment head and the tail, obtains The then excellent live streaming segment of a length of 3rd duration；When the described 3rd a length of first duration and second duration and； It is described supplement segment be in live streaming it is each it is pending live streaming segment head and the tail between the live streaming segment without time interval.
Such as：From the live streaming segment of each first duration, select 5 excellent highest live streaming segments of degree and make For pending live streaming segment, then at this 5 pending live streaming segment head and the tail each increase by 25 seconds supplement segments, when obtaining 5 The excellent live streaming segment of a length of 1 minute.It is described supplement segment be in live streaming it is each it is pending live streaming segment head and the tail between nothing The live streaming segment of time interval.Such as a certain live streaming segment is the 60th second in live video to the in 5 pending live streaming segments Segment between 70 seconds, then the supplement segment of the live streaming segment is just the piece in live video between the 35th second to the 60th second Section and the segment between the 70th second to the 95th second.Since user is often watching the brilliant show of main broadcaster in live streaming Afterwards, just start to send message, that is, there are certain time delays for the increase of message number.Simultaneously because live video is real-time Property, and live content transmission can be influenced be subject to transmission environment, the transmission of live content also there is certain time delay.Cause This, compared with the method for excellent live streaming segment is chosen from the live streaming segment obtained directly according to excellent degree, the present embodiment Method supplements the supplement segment of the 3rd duration in the first place of pending live streaming segment, both ensure that message number and excellent live streaming piece The correspondence of section, that is, make the excellent live streaming segment of acquisition excellent enough, and the whole story of wonderful is covered, see user The content for the excellent live streaming segment seen completely links up as far as possible.
The generation method of live video summary provided in an embodiment of the present invention, passes through the live streaming piece obtained since live streaming The message number that section and number of users corresponding with live streaming segment and user send calculates the excellent journey of each live streaming segment So as to the excellent degree according to the live streaming segment, supplement process is done to obtain excellent live streaming segment to the live streaming segment for degree, And by it is excellent live streaming segment synthesize summary, can give each main broadcaster automatically generate one as far as possible comprising completely link up it is excellent The live video summary of segment is broadcast live, understand the style and characteristic of main broadcaster with alloing user's more convenient and quicker.
As shown in Fig. 2, another flow of the generation method of live video summary provided in an embodiment of the present invention, can wrap It includes：
Step S201, S202, it is corresponding respectively with step S101, S102 of embodiment illustrated in fig. 1, no longer illustrate herein, in detail See the foregoing explanation to Fig. 1 embodiments.
S203 from the live streaming segment of each first duration, chooses the highest live streaming segment of excellent degree as the One pending live streaming segment；Each supplement segment for increasing by the second duration at the first pending live streaming segment head and the tail, obtains duration For the first excellent live streaming segment of the 3rd duration.
