Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a playing method disclosed in an embodiment of the present application, where the method may be executed by a video playing APP in cooperation with a background server, and includes the following steps:
s101: the background server correspondingly stores each caption of the video and the playing start and stop time of each caption.
Wherein, a subtitle is a subtitle with a continuous time interval formed by the play start time and the play end time. For example, a subtitle with a playback time of 1 minute 03 seconds to 1 minute 30 seconds is a single subtitle. Conversely, if there are subtitles for 1 minute 03 second and 19 minutes and subtitles appear again from 1 minute 21 second to 1 minute 30 second, two subtitles appear in the time range from 1 minute 03 second to 1 minute 30 second.
S102: the video playing class APP receives a range of playing rates input by a user.
The playing speed belonging to the playing speed range is the playing speed of the double-speed playing video.
In this embodiment, based on the requirement of the user to play the video at double speed and the requirement of seeing clearly the subtitles during the process of playing the video at double speed, the difference from the prior art is that the user inputs a play rate range, which is called as an original play rate range.
Specifically, the video playback APP may display selectable items in a range of multiple playback rates, where the selectable item selected by the user is the playback rate range input by the user.
For example, the video playing class APP displays selectable items of the playing rate range in the form of multiples of the reference playing rate in the playing interface of the video, such as 1-1.5 times, 1.25-2 times, and the like. The user may select any one of the selectable items by clicking, for example, the user clicks 1.25 times to 2 times, and the original playback rate range of the video playback class APP received the user input is [1.25 × reference playback rate-2 × reference playback rate ].
The original playing speed range has the function of limiting the playing speed of the video, and the adopted playing speed belongs to the original playing speed range no matter the playing speed is reduced or increased subsequently, so as to meet the requirement of double-speed playing of a user.
S103: the video playing class APP selects a first playing rate from the original playing rate range.
Since the subsequent playback rate is reduced based on the original playback rate range, the first playback rate is at least greater than the minimum playback rate of the original playback rate range, so as to leave room for the subsequent reduction of the playback rate.
For example, the original playback rate is in the range of [1.25 × reference playback rate-2 × reference playback rate ], and the first playback rate may be 1.3 times the reference playback rate or 2 times the reference playback rate.
S104: in the process of playing the video at the first playing speed, the video playing type APP obtains each subtitle of the played video and the playing start and stop time of each subtitle from the background server.
S105: and playing the video at the playing start time of each subtitle at a second playing speed according to each subtitle and the playing start and stop time (including the playing start time and the playing end time) of each subtitle by the video playing APP.
The second playing speed is less than the first playing speed, and the second playing speed belongs to the range of the original playing speed.
As can be seen from the above process, the second playing speed is lower than the first playing speed, so that the playing method described in this embodiment reduces the playing speed of the video at the moment when the subtitle starts to be played, so that the user can clearly see the subtitle.
More specifically, the second playback rate is the minimum playback rate in the range of the original playback rates, so that the user can see the subtitles to the greatest extent.
S106: and playing the video at a third playing speed at the playing ending moment of each subtitle according to each subtitle and the playing starting and ending time of each subtitle by the video playing APP.
The third playing speed may be the first playing speed, that is, after the subtitle playing is finished, the first playing speed is restored.
Or, the third playing speed is a playing speed which is greater than the second playing speed and belongs to the original playing speed range. That is, after the subtitle playback ends, the playback rate can be increased to any playback rate in the original playback rate range that is greater than the second playback rate.
As can be seen from the process shown in fig. 1, in the process of playing a video at a double speed, if a subtitle appears in the video, the playing rate of the video is reduced, so that the retention time of the subtitle can be increased, and the subtitle can be seen clearly by a user, thereby improving the user experience.
It should be noted that S106 is an optional step, and after the subtitle playing is finished, the playing rate of the video is increased, so as to further meet the requirement of the user on the magnification playing.
Fig. 2 is a playing method disclosed in an embodiment of the present application, and compared with the method shown in fig. 1, the main difference is that when the playing rate is decreased or increased, a smooth decrease or a smooth increase is adopted to reduce the playing frustration caused by the change of the playing rate.
The method shown in fig. 2 comprises the following steps:
s201: the background server stores the corresponding relation between each subtitle and the playing start and stop time of each subtitle.
In this embodiment, each subtitle has the same meaning as the aforementioned "one subtitle".
S202: the video playing class APP receives an original playing rate range.
S203: the video playing type APP obtains the corresponding relation between each subtitle of a video being played and the playing start and stop time of each subtitle from a background server.
S204: and in the process of playing the video at the first playing speed, the video playing APP sequentially uses the playing speed in the first playing speed set to play the video at the playing starting time of each subtitle according to the corresponding relation.
Wherein, the playing rates in the first playing rate set are decreased in sequence. The decreasing rule may be any one of the following:
1. decreasing by a first preset step.
2. Decreasing with a first preset acceleration. The calculation method for obtaining the decreasing play rate by using the acceleration is the same as that in the prior art, and is not described herein again.
The playback rates in the first set of playback rates are each less than the first playback rate because the goal is to reduce the playback rate.
It should be noted that the playback rates in the first playback rate set all belong to the original playback rate range, so as to meet the user's requirement for double-speed playback.
S205: and the video playing APP plays the video at the playing ending time of each subtitle by using the playing speed in the second playing speed set according to the corresponding relation.
Wherein the playback rates in the second playback rate set are incremented.
The playing speed in the second playing speed set is increased by a second preset step length or a second preset acceleration, and the playing speed in the second playing speed set is greater than the minimum playing speed in the first playing speed set, so that the requirement of increasing the playing speed can be met. It is also possible that the playback rates in the second playback rate set are each greater than the playback rates in the first playback rate set.
The playing rates in the second playing rate set all belong to the original playing rate range.
In the process shown in fig. 2, in the process of playing the subtitles, the playing speed of the video is gradually reduced, and after the subtitles are played, the playing speed of the video is gradually increased, so that the change of the speed has a "smooth" effect, and therefore, the pause and frustration of the video playing can be reduced, and the user experience is further improved.
It should be noted that the above-mentioned smooth increasing of the playing rate and the smooth decreasing of the playing rate are not necessarily performed simultaneously in one playing process. That is, the playing speed can be directly reduced from the first playing speed to the second playing speed, and the playing speed is smoothly increased at the moment of the caption playing ending. In this case, the playback rates in the second playback rate set are each greater than the second playback rate. Or, the playing rate may be smoothly reduced at the start time of the subtitle playing, and the playing rate is directly increased to a third playing rate at the end time of the subtitle playing, where the third playing rate is greater than the playing rate in the first playing rate set (of course, the third playing rate may also be greater than the minimum playing rate in the first playing rate set).
Fig. 3 is a playing method disclosed in the embodiment of the present application, which is mainly different from the methods shown in fig. 1 and fig. 2 in that a user is supported to input a playing rate of playing a video at a fixed magnification, instead of a playing rate range, and the playing rate is reduced or increased based on the fixed playing rate.
The method shown in fig. 3 comprises the following steps:
s301: the background server stores the corresponding relation between each subtitle and the playing start and stop time of each subtitle.
S302: and the video playing APP starts to play the video at a reference playing speed according to a video selection instruction input by a user.
In this embodiment, a user may click any one of videos in the video library, and the video playing APP receives a click instruction for a certain video, that is, receives a video selection instruction.
S303: the video playing APP plays the video at a first playing speed after receiving the first playing speed of the double-speed playing video input by the user.
For example, the user clicks and selects 1.5 times on the playing interface of the video, and the video playing class APP plays the video at a reference playing rate of 1.5 times.
S304: the video playing type APP obtains the corresponding relation between each subtitle of a video being played and the playing start and stop time of each subtitle from a background server.
S305: in the video playing process, the video playing APP reduces the playing speed of the video at the playing starting time of each subtitle.
Wherein, reducing the playing rate of the video may include any one of the following situations:
1. and playing the video at a second playing speed which is less than the first playing speed.
The second playing rate may be a preset playing rate or a randomly selected playing rate.
2. The playing rate of the video is gradually decreased, and the decreasing rule is as described above and will not be described herein.
It should be noted that, in the embodiment shown in fig. 2, since the user selects a play rate range, the decreased lower limit play rate satisfies the limitation of the play rate range, and in the embodiment, since the user selects a play rate value, the lower limit value of the play rate, for example, the reference play rate, may be preset, that is, the play rate is not decreased any more after being decreased to the reference play rate. Of course, the lower limit of the playback rate may not be set.
S306: and increasing the playing speed of the video at the end playing time of each subtitle in the video playing APP.
Wherein, increasing the playing rate of the video may include any one of the following situations:
1. the video is played using a first playback rate.
2. The playing rate of the video is gradually increased. The incremental rule is as described above and will not be described here.
3. The video is played using a play rate greater than the first play rate.
In the method shown in fig. 3, the adjusted play rate is not limited by the play rate range, and therefore, the video play type APP can be preset according to the user experience, which is more flexible.
Fig. 4 is a playing device disclosed in the embodiment of the present application, including: the device comprises a first acquisition module, a second acquisition module and a speed reduction module. Optionally, a speed increasing module can be further included.
The first obtaining module is used for obtaining playing information of each subtitle in a video, and the playing information of any subtitle comprises a playing starting time of the subtitle. The second obtaining module is used for obtaining a first playing speed, wherein the first playing speed is a playing speed adopted by playing the video at a double speed. The speed reduction module is used for reducing the playing speed of the video at the playing starting time of any subtitle in the video in the process of playing the video at the first playing speed.
Optionally, the playing information of any subtitle further includes: the playing end time of the subtitle. The speed increasing module is used for increasing the playing speed of the video at the playing ending time of any subtitle in the video.
For specific implementation of the functions of the modules, reference may be made to the above method embodiments, which are not described herein again.
The playback apparatus shown in fig. 4 reduces the playback rate of the video when the subtitles begin to be played back, and therefore, the possibility that the user will see the subtitles clearly can be increased when the video is played back at a double speed.
