Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A video playback method, an apparatus, a computer device, and a storage medium according to embodiments of the present application are described below with reference to the drawings.
Fig. 1 is a schematic flowchart of a video playing method according to an embodiment of the present application, where the method can be applied to a video playing website and a video player. For convenience of unified description, the following embodiments will explain the present application by taking the video playing method as an example applied to a video player, where the video player performs playing rate control on a video selected to be played by a user.
As shown in fig. 1, the video playing method may include the following steps:
step 101, acquiring a bullet screen file corresponding to a video selected by a user to be played.
With the development of bullet screen culture, most video websites, video APPs and the like support the input and display of bullet screens at present. The barrage refers to a comment subtitle popped up when a video is watched on the network, and the barrages displayed at the same specific time point in the video generally have the same theme, and the larger the number of the barrages, the stronger the topicality of the current video picture is.
When watching videos, the user can release the bullet screen at any time through the bullet screen input frame, and can also open the bullet screen display function to view bullet screens released by other users. The bullet screen that the user has published is stored in bullet screen database, when saving the bullet screen, can be with belonging to all bullet screens storage of same video in same bullet screen file, in the bullet screen database, different bullet screen files can distinguish according to the video identification that corresponds the video, and the video that the video identification can only confirm corresponds.
In this embodiment, when a user selects to play a certain video in the video player, the video player may obtain, according to the video identifier of the video, a bullet screen file corresponding to the video currently selected to be played by the user from the bullet screen database, where the bullet screen file includes all bullet screens related to the video currently selected by the user. For example, if the video currently selected by the user is the first episode of the 25 th episode of the sitcom series, "the video player obtains a bullet screen file matching with the video identifier from a bullet screen database according to the video identifier of the" sitcom ", where the bullet screen file includes all bullet screens from the 1 st episode to the 25 th episode.
Fig. 2 is an exemplary diagram of a part of contents of a bullet screen file, and as shown in fig. 2, the bullet screen file includes a plurality of bullet screens, and each bullet screen is composed of related information of the bullet screen (for example, information such as a corresponding video collection identifier, a timestamp, and the like) and specific contents of the bullet screen.
In a possible implementation manner of the embodiment of the present application, a user may select whether to start the video playing rate automatic adjustment function. For example, an "automatic play rate adjustment" function selection switch may be set in a setting interface of the video player, or an "automatic play rate adjustment" function selection switch may be set in a related information display interface of the video, and when the user starts the function, if the user selects the video, the video player acquires a bullet screen file corresponding to the video currently selected to be played by the user. Therefore, the user can autonomously and selectively control the video playing speed, the personalized requirements of the user can be met, and the user experience is improved.
And 102, acquiring the number of bullet screens in one or more target time periods in the video according to the bullet screen file.
In this embodiment, after the bullet screen file corresponding to the video currently selected to be played by the user is obtained, the number of bullet screens in one or more target time periods in the video can be counted according to the bullet screen file. For example, the number of bullet screens in one or more target time periods in the video may be obtained according to information corresponding to each bullet screen in the bullet screen file, where the information corresponding to each bullet screen may be an album identifier and/or a timestamp, and the timestamp refers to a time when the bullet screen appears in the video content, for example, when the video content plays to 23 '55 ", the timestamp of the bullet screen is 23' 55".
The target time period may be a playing time length of one video content, or may be a part of the playing time length of one video content, for example, one fifth of the playing time length is taken as one target time period.
As an example, for a video including multiple collections, the target time period may be the playing duration of each collection, that is, one collection in the video is used as one target time period, and according to the acquired bullet screen file and the collection identifier corresponding to each bullet screen in the bullet screen file, the number of bullet screens corresponding to each collection may be determined; or, the target time period may also be a part of the play time of one selection, for example, the play time of the selection is 40 minutes, and 30 seconds may be used as one target time period, and each selection is divided into 80 target time periods, so that the number of bullet screens included in each selection in every 30 seconds may be determined according to the acquired bullet screen file and the selection identifier and the timestamp corresponding to each bullet screen in the bullet screen file.
As an example, for a stand-alone video, the target time period may be a fraction of the play-out duration of the video. For example, for a movie, the playing time is 90 minutes, 1 minute can be taken as a target time period, the video content of the movie is divided into 90 target time periods, and the number of bullet screens included in each 1 minute in the movie can be determined according to the acquired bullet screen file and the time stamp corresponding to each bullet screen in the bullet screen file.
And 103, controlling the playing rate of the video in one or more target time periods according to the number of the bullet screens.
In this embodiment, after the number of the barrages in one or more target time periods in the video is determined, the playing rate of the corresponding time period can be controlled according to the number of the barrages included in each time period. Specifically, the larger the number of bullet screens, the slower the playback rate.
As an example, a threshold of the number of bullet screens may be predetermined, after the number of bullet screens in one or more target time periods is obtained, the number of bullet screens in one or more target time periods is compared with the threshold of the number of bullet screens, video content corresponding to a target time period in which the number of bullet screens exceeds the threshold of the number of bullet screens is played at a lower playing speed, and video content corresponding to a target time period in which the number of bullet screens does not exceed the threshold of the number of bullet screens is played at a lower playing speed. For example, the video content corresponding to the target time period in which the number of bullet screens exceeds the threshold of the number of bullet screens is played at a standard playing rate (represented by x), and the video content corresponding to the target time period in which the number of bullet screens does not exceed the threshold of the number of bullet screens is played at a playing rate of 1.5 x.
As an example, a corresponding relation table between different bullet screen numbers and playing rates may be preset, and after the bullet screen numbers of one or more target time periods are obtained, the playing rates of the one or more target time periods are determined by querying the preset relation table. For example, when the target time period is a selected set of videos, the table of the correspondence between the number of barrages and the playing rate may be as shown in table 1; when the target time period is a portion of the playing time of a selected set or an independent video in the video, the table of the correspondence between the number of bullet screens and the playing speed may be as shown in table 2.
TABLE 1
Number of bullet screens (y) Play Rate (x)
y≥6000 0.5x
5000≤y<6000 x
3000≤y<5000 1.1x
y<3000 1.5x
TABLE 2
Number of bullet screens (y) Play Rate (x)
y≥500 0.5x
300≤y<500 x
100≤y<300 1.1x
y<100 1.5x
After the number of the barrages in the target time period is obtained, the play rate corresponding to the target time period can be determined by inquiring the table 1 or the table 2, and then the video content is played according to the determined play rate when the video content is played to the target time period.
In a possible implementation manner of the embodiment of the application, the number of bullet screens with preset intentions included in bullet screen contents in one or more target time periods can be counted by utilizing a semantic recognition technology according to the content of each bullet screen in the acquired bullet screen file. The preset intention may be, for example, fast forward, slow play, etc. For example, for the barrage with the barrage content of "woman is annoying, does not want to see", "the plot is too draggy, wastes time", the corresponding intentions of these barrages are identified as fast-forwarding; for the barrage with the barrage content of 'too fast progress bar walking' and 'wonderful', the corresponding intention of the barrage is identified as slow playing. And then, according to the number of the bullet screens obtained through statistics, the playing speed of one or more target time periods is adjusted.
Further, for the same adjustment mode, different bullet screen numbers can be set corresponding to different playing rates. For example, for fast forward, when the number of barrage is less than 100, the corresponding play rate is the standard play rate; when the number of the barrage is not less than 100 and not more than 200, the corresponding playing speed is (1.1 × standard playing speed); and so on. For slow play, when the number of the barrage is less than 100, the corresponding play rate is the standard play rate; when the number of the barrage is not less than 100 and not more than 200, the corresponding playing speed is (0.9 × standard playing speed); and so on.
For example, if the number of barrages identified as fast-forward intentions in a target time period is 87, and if the number of barrages identified as slow-play intentions is 63, the play rate of the video in the target time period is a standard play rate; if the number of barrage identified as the slow-play intention is 118, the play rate of the video for the target time period is (0.9 × standard play rate). If the number of barrage identified as fast-forward intent is 142 and the number of barrage identified as slow-play intent is 105, the playback rate of the video for the target time period is (1.1 × standard playback rate).
According to the video playing method, the bullet screen file corresponding to the video selected to be played by the user is obtained, the bullet screen quantity of one or more target time periods in the video is obtained according to the bullet screen file, and then the playing speed of the video in the one or more target time periods is controlled according to the bullet screen quantity. Therefore, the purpose of controlling the video playing speed according to the number of the barrage related to the video is achieved, the automatic adjustment of the video playing speed is achieved, the trouble caused by manual fast forward and fast backward execution is avoided, the operation cost is reduced, the convenience of playing speed control is improved, and the series pursuit experience of a user is improved.
As described above, the current internet televisions, video players, etc. can provide different types of videos such as tv series, movies, and art programs for the user to select, and the user can watch tv series or art programs with multiple selections, or can select to watch independent videos such as movies. In a possible implementation manner of the embodiment of the present application, when a video selected by a user to be played is one of the video collections, for example, the user selects the 5 th collection of the drama "western blotting", the play rate of the collection may be controlled according to the number of barrages included in the collection, so as to achieve the purpose of controlling the play rate of different collections according to the wonderful degree of different collections included in the video. Thus, the present application provides another video playing method, and fig. 3 is a schematic flow chart of another video playing method provided in the embodiment of the present application.
As shown in fig. 3, the video playing method may include the following steps:
step 201, acquiring a bullet screen file corresponding to a video selected by a user to be played, wherein the video selected by the user to be played is a selection set in a video set, and the bullet screen file includes a selection set identifier corresponding to each bullet screen.
In this embodiment, when the video selected to be played by the user is one of the video sets, the bullet screen file corresponding to the video selected to be played by the user and acquired by the video player is the bullet screen file corresponding to the video set, that is, the bullet screen file acquired by the video player includes all bullet screens corresponding to each of the video sets.
Step 202, screening the first target barrage matched with the selection identifier of the video according to the selection identifier corresponding to each barrage, and determining the number of all the first target barrages.
In this embodiment, the barrage file acquired by the video player includes the album identifier corresponding to each barrage, and then the first target barrage matched with the album identifier of the video can be screened from the barrage file according to the album identifier corresponding to each barrage, and the number of all the first target barrages is acquired.
For example, if the video currently selected by the user is set 20 of 25 tv series sitter recording, each bullet screen identified by the selection identifier 20 in the acquired bullet screen files may be determined as a first target bullet screen, and the number of bullet screens identified by the selection identifier 20 is counted as the first target bullet screen number.
Step 203, judging whether the number of the first target barrage is larger than a threshold value of the selected barrage of the preset video set.
The selection set barrage threshold may be preset, for example, the selection set barrage threshold is set to 5000.
In this embodiment, after determining the number of first target barrage corresponding to the selection set in the video set currently selected by the user, the number of first target barrage may be compared, and if the number of first target barrage is greater than a preset selection set barrage threshold value, step 205 is executed; otherwise, step 204 is performed.
In a possible implementation manner of the embodiment of the present application, the selection set barrage threshold of the video set may also be determined according to the number of barrages included in a barrage file corresponding to the video set. Specifically, the number of barrages corresponding to each selection set in the video set may be obtained according to the selection set identifier included in each barrage, an average value of the number of barrages corresponding to each selection set is calculated, and the obtained average value is determined as the selection set barrage threshold value of the video set. Therefore, the selection bullet screen threshold value can be set in a targeted manner, so that the accuracy of playing rate control is improved, the problem that the user misses the content of a wonderful selection or spends a long time in play chase due to the fact that the selection bullet screen threshold value is too large or too small is avoided to a certain extent, and play chase experience of the user is further improved.
And 204, acquiring a preset first rate corresponding to the number of the first target barrage, and playing all contents of the video according to the first rate.
Step 205, obtaining a preset second rate corresponding to the first target bullet screen quantity, and playing the whole content of the video according to the second rate, wherein the second rate is smaller than the first rate.
In this embodiment, when it is known that the number of the first target barrage is less than or equal to the selection barrage threshold value through comparison, a preset first rate corresponding to the number of the first target barrage is obtained, and all contents of the video are played according to the first rate; and when the comparison shows that the number of the first target barrage is larger than the selection barrage threshold value, acquiring a preset second rate corresponding to the number of the first barrage targets, and playing the whole content of the video according to the second rate, wherein the second rate is smaller than the first rate.
For example, assume that the preset corresponding relationship between the first target barrage number and the playing rate is: the number of the first target barrage is larger than the threshold value of the selection barrage, and the playing speed is x; the number of the first target barrage is less than or equal to the threshold value of the selection barrage, and the playing speed is 1.5 x. Assuming that the selection currently selected by the user is the "journey to the west" set 5, the number of first target barrage corresponding to the selection is 3700, and the threshold value of the selection barrage is 3500, it may be determined that the first rate corresponding to the number of first target barrage is x, and the video player plays all the contents of the "journey to the west" set 5 at the play rate of x.
In the video playing method of this embodiment, when a video selected by a user to be played is a selected set in a video set, a first target barrage matched with an identifier of the selected set of the video is screened according to the identifier of the selected set corresponding to each barrage, and the number of all first target barrages is determined, and then the number of the first target barrages is compared with a preset threshold value of the selected set barrage of the video set, when the number of the first target barrages is less than or equal to the threshold value of the selected set barrage, a preset first rate corresponding to the number of the first target barrages is obtained, and all videos are played according to the first rate, when the number of the first target barrages is greater than the threshold value of the selected set, a preset second rate corresponding to the number of the first barrage targets is obtained, the second rate is less than the first rate, and the entire content of the video is played according to the second rate, thereby achieving the purpose of controlling the playing rate of the selected set according to the number of the barrages of the selected set, automatic adjustment of the play rates of different selections is achieved.
The video playing method disclosed by the application can also adjust the playing speed of different video segments in the video according to the wonderful degree of the video content for the video selected to be played by the user at present, so that the user can efficiently chase after the play without missing the wonderful video segments.
Fig. 4 is a schematic flowchart of another video playing method according to an embodiment of the present application.
As shown in fig. 4, the video playing method may include the following steps:
step 301, acquiring a bullet screen file corresponding to a video selected to be played by a user, where the video selected to be played by the user is an option in a video set, and the bullet screen file includes an option identifier and a timestamp corresponding to each bullet screen.
Step 302, screening second target barrages matched with the selection identifications of the videos and the preset time period identifications according to the selection identifications and the time stamps corresponding to each barrage, and determining the number of all the second target barrages.
The period identifier may be preset, for example, for each selection in the video set, each selection may be divided into a plurality of time periods, and each time period may be marked with a unique period identifier.
In this embodiment, the barrage file acquired by the video player includes the album identifier and the timestamp corresponding to each barrage, and according to the album and the timestamp corresponding to each barrage, the second target barrage matched with the album identifier of the video currently selected by the user and the preset time interval identifier can be screened from the barrage file, and the number of all the second target barrages corresponding to each time interval identifier is determined.
For example, suppose that the playing time of each selection of 25 television series "western shorthand" is 40 minutes, 30 seconds is taken as a time period, each selection is divided into 80 time periods, and the time period identifier of each time period is 1 to 80 in turn, that is, the time period identifier of 0 '0 "to 0' 30" in each selection is 1, the time period identifier of 0 '31 "to 1' 00" is 2, and so on, the time period identifier of 39 '31 "to 40' 00" is 80. Assuming that the selection currently selected by the user is set 5 of the western-style notes, and the corresponding selection identifier of one of the barrages is 5 and the timestamp is 0 '21' in the acquired barrage file, it can be determined that the barrage matches with the time identifier 1 in the set 5, and the barrage is one of the second target barrages in the video segments with the time interval identifier 1 in the set 5. According to the mode, all second target barrage respectively matched with the time interval identifications in the 5 th set can be screened out from the barrage file, and the number of all second target barrage matched with the time interval identifications is counted for each time interval identification and is used as the number of the second target barrage of the time interval identification.
And 303, acquiring the number of bullet screens corresponding to each preset unit time interval in the video according to the collection identification and the timestamp contained in each bullet screen.

Assuming that the selection set currently selected by the user is the 'journey to the west' set 5, the number of second target barrage matched with the time interval identifier 1 in the selection set is 330, the number of second target barrage matched with the time interval identifier 2 is 270, and the threshold value of the video barrage is 300, when the video player plays the 'journey to the west' set 5, the video segment corresponding to the time interval identifier 1 is played at the play rate of 0.5x, and the video segment corresponding to the time interval identifier 2 is played at the play rate of x.
