Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an aspect of an embodiment of the present invention, there is provided a method for controlling a play speed. Alternatively, the above-mentioned control method of the playing speed can be applied, but not limited, to the application environment as shown in fig. 1. As shown in fig. 1, a target client of a target application is running on a terminal device 102, and the target client can play a media file (e.g., a video), and the first media file is currently playing on the target client. The terminal device 102 may be connected to a server 106 through the network 104, and the server 106 may be a background server of the target client for providing the media file to the target client for playing.
The terminal device 102 or the server 106 may determine a first time required to move from the current location of the terminal device 102 to the target location; and adjusting the playing speed of the first media file on the target client according to the first time.
Alternatively, the target position may be a destination of a current trip of a target object corresponding to the terminal device 102.
Optionally, in this embodiment, the terminal device 102 may be a terminal device configured with the target client, and may include but is not limited to at least one of the following: mobile phones (such as Android phones, iOS phones, etc.), notebook computers, tablet computers, palm computers, MID (Mobile Internet Devices), PAD, desktop computers, etc. Such networks may include, but are not limited to: a wired network, a wireless network, wherein the wired network comprises: a local area network, a metropolitan area network, and a wide area network, the wireless network comprising: bluetooth, WIFI, and other networks that enable wireless communication. The server may be a single server or a server cluster composed of a plurality of servers. The above is only an example, and the present embodiment is not limited to this.
Optionally, in this embodiment, as an optional implementation manner, the method may be executed by a server, or may be executed by a terminal device, or may be executed by both the server and the terminal device. As shown in fig. 2, the flow of the method for controlling the play speed may include the steps of:
step S202, determining a first time required for moving from the current position of the terminal to the target position;
step S204, according to the first time, the playing speed of the first media file on the target client is adjusted.
Optionally, the above-mentioned control method of the playing speed may be, but not limited to, in the process of playing the media file using the client or in other scenes for controlling the playing speed of the client.
For example, a user plays a current video using a target client running on a terminal. The terminal or the background server of the target client may determine a first time required for the user to reach the destination (corresponding to the target location); and adjusting the playing speed of the current video according to the first time. For example, if the current video cannot be played at the current playing speed until the destination is reached, the playing speed of the current video may be adjusted faster so that as much content as possible is played before the user reaches the destination. For another example, if the current video has been played at the current playing speed for a period of time before the destination is reached, the playing speed of the current video may be slowed down to reduce the blank time that the user has in the process of reaching the destination.
By the embodiment, a first time required for moving from the current position of the terminal to the target position is determined by adopting a mode of adaptively adjusting the playing speed; according to the first time, the playing speed of the first media file on the target client is adjusted, the technical problems of complex operation and poor user experience existing in a playing speed control mode in the related technology are solved, the operation required for adjusting the video playing speed is simplified, and the user experience is improved.
The method for controlling the playback speed will be described with reference to fig. 2.
In step S202, a first time required to move from the current position of the terminal to the target position is determined.
The terminal can be operated with a target client, and the target client can be a client with a media file playing function. The target client may be a client that logs in using a target account, or may be a client that exists in a web page or other form, where the target account is used to identify a target object. The target client may also be a client that is not logged in using any account, wherein the terminal identification of the terminal may be used to identify the target object.
The media file can be a video, a PPT or other files with continuous playing function in time.
Optionally, in this embodiment, before determining a first time required to move from the current location of the terminal to the target location, obtaining, by the target client, selection information of a target object corresponding to the terminal, where the selection information includes: a target location.
Before or during the playing of the first media file is started, the user may set the play mode of the target client to the road mode by performing a specific operation. In the route mode, the user can set selection information (route-related information) related to the current route, and the selection information may include: target location (destination of current trip).
In addition to the target location, the selection information may include one of the following: the vehicle used to complete the current trip (e.g., bus, train, private car, walk, etc.). For different vehicles, the selection information may further include: vehicle information (e.g., train number information of a bus, train, bus, etc.) corresponding to a vehicle.
For example, after the user selects the playing mode as the route mode, the user enters the setting interface shown in fig. 3, the user may select information such as a destination of the current route, a vehicle used, a video to be played, and the like, the selected vehicle is a bus, and the user may further select information of the number of buses, a driving mode of the bus, and the like. When the selection box after the video to be played is selected is clicked, the user can jump to the video selection list to be played as shown in fig. 4. The user may select a video to be played or a designated episode.
For another example, if the user selects the route mode during playing the media file, the media file to be played may be defaulted as the current media file without the user selecting the media file to be played.
Through the embodiment, the target client side obtains the selection information containing the target position, so that the target position can be conveniently determined, and the accuracy of determining at the first time is further ensured.
In addition to the target location, the current location of the terminal may be obtained by a positioning system (e.g., global positioning system, GPS) on the terminal to determine a first time to move from the current location to the target location. The operation of acquiring the current position is event-triggered (for example, detecting that the road mode is entered, detecting an operation instruction for triggering the play speed update), or may be periodically triggered (for example, after the road mode is entered, periodically triggering the play speed update, periodically determining the first time and the remaining time, and updating the play speed).
The first time for moving from the current position to the target position may be determined in various ways, for example, the first time may be determined according to a real-time speed of the terminal and a moving path from the current position to the target position, the first time may be determined according to an average speed of the terminal and a moving path from the current position to the target position, and the first time may be determined according to auxiliary information (e.g., a train schedule, time information provided by a third party), for example.
As an alternative embodiment, determining the first time required to move from the current location of the terminal to the target location may include: determining a moving route for moving from a current position to a target position; acquiring the current moving speed of the terminal through a speed sensor on the terminal; a first time required to move to the target position along the movement route at the movement speed is determined.
After the user selects to enter the road mode, the current position and the target position of the terminal can be obtained, and a moving route from the current position to the target position is planned. In the case where there are a plurality of routes from the current location to the destination location, a plurality of routes may be displayed on the destination client (for example, as shown in fig. 5), and a moving route may be determined according to the selection of the user. For the determined movement route, the remaining length of the movement route (the distance S from the current position to the target position) may be calculated.
In the process of playing the first media file using the route mode, the target client may display a map interface including a moving route according to the operation of the user, and change the moving route according to the detected selection information.
The terminal may be provided with a speed sensor, and may determine a current moving speed of the terminal (target object) according to speed information of the terminal detected by the speed sensor, or may determine the current moving speed of the target object in other manners (for example, the moving speed of the terminal may be determined by using positioning information of the terminal and by a distance moved in a short time). It should be noted that the determination method of the moving speed may be similar to the method of detecting the moving speed of the terminal by the map software, and is not described herein again.
After the moving speed is determined, a first time required for moving to the target position according to the moving route at the current moving speed may be determined according to the distance from the current position to the target position and the current moving speed.
According to the embodiment, the current moving speed of the user determined by the speed sensor on the terminal determines the first time required for moving to the target position at the current moving speed according to the planned moving route, the determination mode is simple, and the occupation of software and hardware resources of the terminal is reduced.
As another alternative, determining the first time required to move from the current location of the terminal to the target location may include: determining a moving route from a current position to a target position; determining the stroke length of the finished stroke of the terminal and a second time consumed for finishing the finished stroke; determining the average moving speed for completing the finished stroke according to the stroke length and the second time; a first time required to move to a target location along a movement route at an average movement speed is determined.
The movement route can be planned in the same manner as described above. After the moving route is planned, the length of the completed journey (the length of the journey from the initial position for collecting the journey information to the current position) and the second time consumed for completing the completed journey can be recorded, and the average moving speed for completing the completed journey is calculated according to the completed journey length and the second time.
After determining the average moving speed, a first time required to move to the target location along the moving route at the average moving speed may be determined based on the distance from the current location to the target location and the average moving speed.
By the embodiment, the first time required for moving to the target position according to the planned moving route at the average moving speed is determined according to the average moving speed of the finished journey, so that the inaccurate determination of the moving speed caused by the change of the moving speed of the terminal (such as waiting for a red light, parking, acceleration and deceleration) can be avoided, and the accuracy of the determined first time is improved.
As still another alternative embodiment, determining the first time required to move from the current location of the terminal to the target location may include: the method comprises the steps that vehicle information is obtained through a target client, wherein the vehicle information is used for representing a vehicle used for moving from a current position to a target position, the vehicle runs according to a preset running route, one or more preset parking positions are arranged on the running route, each parking position in the one or more parking positions corresponds to one parking moment, and the one or more parking positions correspond to the target parking position corresponding to the target position; determining a target parking time corresponding to the target parking position; and determining the time difference between the target parking time and the current time as the first time.
For public transportation, each vehicle may have a predetermined stop location or locations, and each stop location may correspond to a predetermined stop time, or a predicted stop time (e.g., a predicted stop time for map-like software). The target position of the current trip may correspond to a target stop position, which corresponds to a target stop time. And if the time difference between the current time and the target stop time is smaller than the first time, the first time is the time difference between the target stop time and the current time.
For example, for a 10-line subway from an origin station a to a destination station B of 13:00 departure, a station C is a station corresponding to a target position, the stop time of the station C is 13:40, the target stop time corresponding to the target position is 13:40, and the first time is 20 minutes if the current time is 13: 20.
By the embodiment, the first time is determined by using the auxiliary information, so that the process of determining the first time can be simplified, and the accuracy of determining the first time is improved. And the first time is determined according to the stopping time of the vehicle, so that the first media file can be guaranteed to be played before the vehicle is taken, the potential safety hazard caused by the fact that a user watches the first media file when walking is avoided, and the safety of the user is guaranteed.
In step S204, a playing speed of the first media file on the target client is adjusted according to the first time.
After the first time is determined, the playing speed of the first media file can be adjusted according to the first time, the first media file is a media file played on a target client, and the target client can be a client running on a terminal.
Besides the first time, the remaining playing time of the first media file can be determined, and the remaining time refers to: the time required for the target client to play the first media file at the current playing speed may be: the playing from the current time to the last time of the first media file may also refer to: play from the current time to the time when the end of the slice starts (e.g., set to skip the beginning and end of the slice).
As yet another alternative implementation, determining the remaining time for the target client to play the currently played first media file may include: determining a first moment of current playing of a first media file and a second moment of beginning of the end of the first media file; and determining the time required for playing from the first time to the second time according to the first playing speed as the remaining playing time.
For example, if the total duration of the first media file is 1 hour, 58 minutes and 48 seconds, the current playing time is 1 hour, 20 minutes and 00 seconds, and the ending time of the first media file is 1 hour, 56 minutes and 00 seconds, the remaining playing time may be 38 minutes and 48 seconds, or 36 minutes.
By the embodiment, the remaining duration of the feature of the media file is used as the remaining time of the first media file, so that unnecessary play time of the end of the clip can be removed, and the accuracy of calculating the remaining time can be ensured.
Optionally, the remaining playing time may also be the total playing time of a particular segment (e.g., a highlight segment) remaining in the first media file, which may be identified together when the first media file is published, or may be identified before the target object plays the first media file.
After the remaining playing time is determined, the first time and the remaining playing time may be compared, and the playing speed of the first media file may be adjusted according to the comparison result.
Optionally, in this embodiment, when the first time is less than the remaining playing time and the current first playing speed of the first media file is less than the maximum playing speed allowed by the target client, the playing speed of the first media file is adjusted from the first playing speed to a second playing speed, where the second playing speed is greater than the first playing speed.
If the first time is less than the remaining playing time, and the current first playing speed of the first media file is less than the maximum playing speed allowed by the target client, the first media file is played at the current playing speed, and when the first media file reaches the target position, the first media file cannot be played completely, so that the playing speed of the first media file can be increased, and more media file contents can be played as far as possible.
By the embodiment, under the condition that the first time is less than the remaining playing time and the current first playing speed of the first media file is less than the maximum playing speed allowed by the target client, the playing speed of the first media file is increased, the capability of the target client for playing the media file can be improved, and the user experience is improved.
The playback speed allowed by the target client may be various, for example, as shown in fig. 6, normal playback (1 × speed), low speed (0.5 × speed, 0.75 × speed, etc.), high speed (1.25 × speed, 1.5 × speed, 1.75 × speed, 2 × speed, 2.5 × speed, 3 × speed, etc.).
The play speed of the first media file may be increased in a number of ways. For example, the play speed of the first media file may be increased from the first play speed by a play speed one step higher than the first play speed (e.g., from 1.5 times to 1.75 times).
Optionally, in this embodiment, after determining the remaining playing time of the first media file, determining a ratio of the remaining playing time to the first time; based on the ratio, an adjusted play speed (e.g., a second play speed, a third play speed) is determined.
Before adjusting the playing speed, the adjusted playing speed may be determined according to a ratio of the remaining playing time to the first time (the first ratio, for example, the determined first time is 20 minutes, the remaining time is 30 minutes, and the ratio of the remaining time to the first time is 1.5).
Through the embodiment, the adjusted playing speed is determined according to the ratio of the remaining playing time to the first time, and the rationality of the adjustment of the playing speed can be improved.
It should be noted that the adjusted play speed may also be determined according to a ratio of the remaining duration of the first media file (the time required for playing at the normal play speed) to the first time. For example, if the first time is 15 minutes, the video content of the first video that is still 30 minutes is not played, and the current playing speed is 1.5 times, the remaining duration of the first video is 30 minutes, and the remaining playing time for playing the first video is 20 minutes, then the ratio of the remaining playing time to the first time is: 2, the ratio of the remaining duration of the first video to the first time is: 4/3.
Optionally, in this embodiment, before the playing speed of the first media file is adjusted from the first playing speed to the second playing speed, a ratio of the remaining playing time to the first time may be determined, and in a case that a product of the ratio and the first playing speed is greater than or equal to the maximum playing speed, the maximum playing speed is determined as the second playing speed; and under the condition that the product of the ratio and the first playing speed is less than the maximum playing speed, determining the minimum playing speed which is greater than or equal to the product of the ratio and the first playing speed in a plurality of playing speeds allowed by the target client as a second playing speed.
After determining the ratio of the remaining playing time to the first time (first ratio), the product of the ratio and the first playing speed is the playing speed (target playing speed) required for playing the first media file at the first time. The playback speed may not be the playback speed allowed by the target client. After the target playing speed is determined, a second playing speed may be determined according to a relationship between the target playing speed and a playing speed allowed by the target client.
If the target play speed is greater than or equal to the maximum play speed, the maximum play speed may be determined as the second play speed. If the target play speed is less than the maximum play speed, a minimum play speed greater than or equal to the target play speed among a plurality of play speeds allowed by the target client may be determined as the second play speed.
For example, if the determined first ratio is 4/3, and the current playback speed is 1.5 times, the target playback speed is 2 times, the maximum playback speed allowed by the target client is 3 times, and the playback speed allowed by the target client is 2 times, the second playback speed is 2 times.
For another example, if the determined first ratio is 1.3, and the current playback speed is 1.25 times, the target playback speed is 1.625 times, the maximum playback speed allowed by the target client is 3 times, and if the 1.75 times speed is the minimum playback speed allowed by the target client that is greater than or equal to the target playback speed, the second playback speed is 1.75 times speed.
For another example, if the determined first ratio is 2, and the current playing speed is 2 times, the target playing speed is 4 times, the maximum playing speed allowed by the target client is 3 times, and the target playing speed is greater than the maximum playing speed, the second playing speed is 3 times.
It should be noted that the target playing speed may also be determined according to the remaining duration of the first media file and the first time, and a ratio of the remaining duration of the first media file to the first time may be used as the target playing speed.
Through the embodiment, the second playing speed is determined according to the comparison between the target playing speed (the product of the ratio and the first playing speed) and the playing speed allowed by the client, so that the setting of the second playing speed is facilitated, and the accuracy of determining the second playing speed can be improved.
The first time length may also be greater than or equal to the remaining time length, the first media file may be played back at the current playback speed before the destination is reached, no operation may be performed, and the first media file may be played back at the current speed.
Optionally, in this embodiment, after determining the remaining time for the target client to play the currently played first media file, in a case that the first time is greater than the remaining time and the current first play speed of the first media file is greater than the minimum play speed (or the normal play speed) allowed by the target client, the play speed of the first media file may be adjusted from the first play speed to a third play speed, where the third play speed is less than the first play speed.
The way of adjusting the play speed may be: first, determining a target play speed (the target play speed may be similar to the foregoing manner), and in the case that the target play speed is less than or equal to the minimum play speed, determining the minimum play speed as a second play speed; and under the condition that the target playing speed is greater than the minimum playing speed, determining the minimum playing speed which is greater than or equal to the target playing speed in a plurality of playing speeds allowed by the target client as a third playing speed.

When the video is played, the time consumed by the user to reach the destination is estimated by calculating the current movement speed of the user, the playing speed is dynamically adjusted, and the user just finishes playing when the user reaches the vicinity of the destination.
As shown in fig. 7, the method for controlling the play speed in the present example may include the steps of:
in step S702, the video is set to the road mode.
The user can set the video play mode to the road mode on the client.
In step S704, a destination is set.
The user may select a target location on the client and calculate a route.
Step S706, calculates the path length of the route from the current position to the destination.
The background server of the terminal or the target client calculates the path length S of the route from the current position to the destination (the distance from the current position to the target location).
Step S708, the current movement speed of the user is obtained in real time.
The background server of the terminal or the target client may detect the movement speed V of the current user.
In step S710, the time required to reach the destination is calculated.
The terminal or the background server of the target client can calculate the time (first time) still needed to reach the target location: and T is S/V.
In step S712, the remaining playing time of the video is calculated.
The background server of the terminal or the target client may calculate the remaining playing time T2 of the current video.
Step S714, determining whether the playing is finished, if so, finishing, otherwise, executing step S716.
In step S716, the current double speed of the video is set to (T2/T).
The background server of the terminal or the target client can set the playing speed N which is currently required by the video to be T2/T. The double-speed playing refers to playing at a certain speed multiplied on the basis of the normal playing speed. The video playing interface for setting the double speed can be as shown in fig. 8.
With this example, reasonable viewing or listening times can be scheduled for users on the way according to the user's route planning time: the playing speed of the video is dynamically adjusted, when the video is long or the episode is large, the user can be guaranteed to finish normally (or finish the appointed episode) when arriving near the destination, and the integrity experience of watching the video or listening to the audio on the way of the user is improved.
