Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise 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 the embodiment of the invention, a control method of playing speed is provided. Alternatively, the above-mentioned control method of the play speed may be applied, but not limited to, in 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, where the target client may play a media file (e.g., video), and the target client currently plays a first media file. Terminal device 102 may be coupled to server 106 via network 104, and server 106 may be a background server of the target client for providing media files to the target client for playback.
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 according to the first time, adjusting the playing speed of the first media file on the target client.
Alternatively, the target position may be a destination of a current trip of a target object corresponding to the terminal device 102.
Alternatively, in the present 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: a mobile phone (e.g., android mobile phone, iOS mobile phone, etc.), a notebook computer, a tablet computer, a palm computer, MID (Mobile Internet Devices, mobile internet device), PAD, desktop computer, etc. The network may include, but is not limited to: a wired network, a wireless network, wherein the wired network comprises: local area networks, metropolitan area networks, and wide area networks, the wireless network comprising: bluetooth, WIFI, and other networks that enable wireless communications. The server may be a single server or a server cluster composed of a plurality of servers. The above is merely an example, and the present embodiment is not limited thereto.
Alternatively, in this embodiment, as an optional implementation manner, the method may be performed by a server, may be performed by a terminal device, or may be performed by the server and the terminal device together, and in this embodiment, the description is given by way of example by the server. As shown in fig. 2, the flow of the above-mentioned control method for playing 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.
Alternatively, the above-mentioned control method of playing speed may be, but not limited to, in the process of playing the media file using the client or in other scenes of 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 according to the first time, adjusting the playing speed of the current video. For example, if the current video cannot be played at the current play speed before reaching the destination, the play speed of the current video may be adjusted so as to play as much content as possible before the user reaches the destination. For another example, if the current video has been played at the current play speed for a period of time before the destination is reached, the play 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 control mode of the playing speed in the related technology is solved, the technical problems of complex operation and poor user experience exist, 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 provided with a client with a media file playing function. The target client may be a client logged in using a target account, or may be a client existing in a web page or other forms, 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 number, wherein the terminal identification of the terminal may be used to identify the target object.
The media file may be a video, PPT or other file having a continuous play function over time.
Optionally, in this embodiment, before determining a first time required for moving from a current location of the terminal to the target location, selection information of a target object corresponding to the terminal is acquired by the target client, where the selection information includes: a target location.
Before starting playing the first media file or during playing the first media file, the user may set the play mode of the target client to the route mode by performing a specific operation. In the route mode, the user may 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: vehicles used to complete the current trip (e.g., buses, trains, private cars, walking, etc.). The selection information may also include, for different vehicles: vehicle information (e.g., number of buses, trains, buses, etc.) corresponding to the vehicle.
For example, after the user selects the play mode as the route mode, the user enters the setting interface shown in fig. 3, and the user can select the destination of the current journey, the used vehicle, the video to be played and other information, and the selected vehicle is a bus, and the user can further select the information of the number of buses, the running mode of the vehicle and the like. When the selection box after selecting the video to be played is clicked, the video to be played selection list as shown in fig. 4 may be skipped. The user may select a video to be played or a specified episode.
For another example, if the user selects the route mode during playing of the media file, the media file to be played may be defaulted to the current media file without the user selecting the media file to be played.
According to 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 the first time determination 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 may be event-triggered (e.g., detecting entry into the waymode, detecting an operation instruction for triggering a play-speed update), or may be periodically-triggered (e.g., after entry into the waymode, periodically triggering a play-speed update, periodically determining a first time and a 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 manners, 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, for example, 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, for example, and for example, the first time may be determined according to auxiliary information (e.g., a train number schedule, time information provided by a third party).
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 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 route mode, the current position and the target position of the terminal may be acquired, and a moving route from the current position to the target position may be planned. In the case where there are a plurality of routes from the current location to the target location, a plurality of routes may be displayed on the target client (for example, as shown in fig. 5), and a moving route may be determined according to the user's selection. For the determined moving route, the remaining length of the moving route (the distance S from the current position to the target position) may be calculated.
In playing the first media file using the route mode, the target client may display a map interface including a moving route according to a user operation and change the moving route according to the detected selection information.
The terminal may be provided with a speed sensor, and the current moving speed of the terminal (target object) may be determined according to the speed information of the terminal detected by the speed sensor, or the current moving speed of the target object may be determined by other manners (for example, the moving speed of the terminal may be determined by using positioning information of the terminal and a distance moved in a shorter time). It should be noted that, the determination manner of the moving speed may be similar to the manner of detecting the moving speed of the terminal by the map software, which is not described herein.
After determining the moving speed, a first time required to move 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 method and the device for determining the moving speed of the mobile terminal, the current moving speed of the user is determined by the speed sensor on the mobile terminal, the first time required for moving to the target position according to the planned moving route at the current moving speed is determined, the determining mode is simple, and occupation of software and hardware resources of the mobile terminal is reduced.
As another 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 from the current position to the target position; determining a stroke length of the stroke completed by the terminal and a second time consumed for completing the stroke completed by the terminal; determining an average moving speed of the completed stroke according to the stroke length and the second time; a first time required to move to the target position along the movement route at the average movement speed is determined.
The moving route may be planned in the same manner as described previously. After the travel route is planned, the stroke length of the completed stroke (the stroke length from the initial position where the stroke information is acquired to the current position) and the second time consumed for completing the completed stroke may be recorded, and the average travel speed for completing the completed stroke may be calculated according to the completed stroke length and the second time.
After determining the average moving speed, a first time required to move to the target position according to the moving route at the average moving speed may be determined according to the distance from the current position to the target position and the average moving speed.
According to the embodiment, according to the average moving speed of the completed travel, the first time required for moving to the target position according to the planned moving route at the average moving speed is determined, inaccurate moving speed determination caused by moving speed change (such as waiting for red light, stopping, acceleration and deceleration and the like) of the terminal can be avoided, and accuracy of the determined first time is improved.
As yet another alternative embodiment, determining the first time required to move from the current location of the terminal to the target location may include: acquiring vehicle information through a target client, wherein the vehicle information is used for representing a vehicle used by moving from a current position to a target position, the vehicle runs according to a preset running route, the vehicle has one or more preset stop positions on the running route, each stop position in the one or more stop positions corresponds to one stop moment, and the one or more stop positions correspond to the target stop 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 vehicles, each vehicle may have a predetermined one or more docking locations, each of which may correspond to a predetermined docking moment, or an estimated docking moment (e.g., an estimated docking moment of map-like software). The target position of the current trip may correspond to a target docking position, which corresponds to a target docking time. And if the time difference between the current time and the target stopping time is the time difference between the target stopping time and the current time.
For example, for a 10 th subway from a start station a to a final station B, which starts at 13:00, 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, the current time is 13:20, and the first time is 20 minutes.
According to the embodiment, the auxiliary information is used for determining the first time, so that the flow 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 vehicle parking time, so that the first media file can be played before the riding of the vehicle is finished as far as possible, potential safety hazards caused by watching the first media file when a user walks are avoided, and the safety of the user is ensured.
In step S204, the 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.
In addition to the first time, a remaining play time of the first media file may be determined, where the remaining time refers to: the target client end plays the first media file according to the time required by the current playing speed, and the playing of the first media file can be: the time from the current time to the last time of the first media file may also be: from the current time to the time at which the trailer starts (e.g., set to skip the trailer and the head).
As yet another alternative embodiment, 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 the first media file and a second moment of beginning of a tail of the first media file; the time required for playing from the first time to the second time according to the first playing speed is determined as the remaining playing time.
For example, the total duration of the first media file is 1 hour 58 minutes 48 seconds, the current playing time is 1 hour 20 minutes 00 seconds, and the beginning time of the end of the clip is 1 hour 56 minutes 00 seconds, so that the remaining playing time can be 38 minutes 48 seconds or 36 minutes.
By using the remaining duration of the positive film of the media file as the remaining time of the first media file, the unnecessary tail playing time can be removed, and the accuracy of the remaining time calculation is ensured.
Alternatively, the remaining playing time may be the total playing time of the specific segments (e.g., highlight segments) remaining in the first media file, where the specific segments 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 smaller than the remaining playing time and the current first playing speed of the first media file is smaller 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 playing speed of the first media file can be increased, so that more media file contents can be played as much as possible.
According to the embodiment, when the first time is smaller than the remaining playing time and the current first playing speed of the first media file is smaller than the maximum playing speed allowed by the target client, the playing speed of the first media file is fast, the playing capacity of the target client for playing the media file can be improved, and 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-time speed), low-time speed (0.5-time speed, 0.75-time speed, etc.), high-time speed (1.25-time speed, 1.5-time speed, 1.75-time speed, 2-time speed, 2.5-time speed, 3-time speed, etc.).
The playing speed of the first media file may be increased in a number of ways. For example, the playback speed of the first media file may be increased by one level higher than the first playback speed (e.g., from 1.5 times speed to 1.75 times speed).
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; and determining the adjusted playing speed (e.g. the second playing speed and the third playing speed) according to the ratio.
Before adjusting the play speed, the adjusted play speed may be determined according to a ratio of the remaining play 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).
According to the embodiment, the adjusted playing speed is determined according to the ratio of the remaining playing time to the first time, so that the rationality of playing speed adjustment can be improved.
It should be noted that, the adjusted playing speed may also be determined according to a ratio of the remaining duration of the first media file (time required for playing according to the normal playing speed) to the first time. For example, the first time is 15 minutes, the video content of the first video which remains for 30 minutes is not played, the current playing speed is 1.5 times of the current playing speed, the remaining duration of the first video is 30 minutes, the remaining playing time of playing the first video is 20 minutes, and 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 where 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 smaller than the maximum playing speed, determining the minimum playing speed which is larger 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 the 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 play speed may not be the play speed allowed by the target client. After determining the target playing speed, the second playing speed may be determined according to the relationship between the target playing speed and the 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 playing speed is smaller than the maximum playing speed, the minimum playing speed which is larger than or equal to the target playing speed in the plurality of playing speeds allowed by the target client can be determined to be the second playing speed.
For example, the determined first ratio is 4/3, the current playing speed is 1.5 times of speed, the target playing speed is 2 times of speed, the maximum playing speed allowed by the target client is 3 times of speed, the 2 times of speed is 2 times of speed allowed by the target client, and the second playing speed is 2 times of speed.
For another example, the determined first ratio is 1.3, the current playing speed is 1.25 times the current playing speed, the target playing speed is 1.625 times the current playing speed, the maximum playing speed allowed by the target client is 3 times the current playing speed, the 1.75 times the minimum playing speed allowed by the target client and greater than or equal to the target playing speed, and the second playing speed is 1.75 times the current playing speed.
For another example, the determined first ratio is 2, the current playing speed is 2 times of speed, the target playing speed is 4 times of speed, the maximum playing speed allowed by the target client is 3 times of speed, the target playing speed is greater than the maximum playing speed, and the second playing speed is 3 times of speed.
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 the ratio of the remaining duration of the first media file to the first time may be used as the target playing speed.
According to the embodiment, the second playing speed is determined according to comparison between the target playing speed (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 be greater than or equal to the remaining time length, and the first media file may be played before reaching the destination according to the current playing speed, and may not perform any operation, and the first media file may be played according to the current playing speed.
Optionally, in this embodiment, after determining the remaining time for the target client to play the first media file currently played, if the first time is greater than the remaining time and the current first playing speed of the first media file is greater than the minimum playing speed (or the normal playing speed) allowed by the target client, the playing speed of the first media file may be adjusted from the first playing speed to a third playing speed, where the third playing speed is less than the first playing speed.
The mode of adjusting the playing speed can be as follows: first, determining a target playing speed (the target playing speed may be similar to the foregoing), and determining the minimum playing speed as a second playing speed when the target playing speed is less than or equal to the minimum playing 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.

For event triggering, the operation of automatically adding the associated media files can be executed, more episodes can be automatically added to participate in the calculation of the residual time of the total media files, the completeness of viewing the episodes by the user can be ensured, and the user experience is improved.
The following describes a control method of the play speed in the present embodiment in conjunction with an alternative example. The control method of the playing speed in this example can dynamically adjust the speed of media playing according to the time planned by the user path. When playing video, the time consumption of the user reaching the destination is estimated by calculating the current motion speed of the user, the playing speed is dynamically adjusted, and the user just plays when the user reaches the vicinity of the destination.
As shown in fig. 7, the control method of the play speed in this example may include the steps of:
in step S702, the video is set to the route mode.
The user may set the video play mode to the route mode on the client.
Step S704, setting a destination.
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 location to the destination.
The terminal or the background server of the target client calculates the path length S (the distance from the current location to the target site) of the route from the current location to the destination.
Step S708, the current movement speed of the user is obtained in real time.
The terminal or the background server of the target client can detect the motion 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 may calculate the time (first time) that it also needs to consume to reach the target site: t=s/V.
Step S712, calculating the remaining play time of the video.
The terminal or the background server of the target client may calculate the remaining play time T2 of the current video.
Step S714, determine whether the playing is finished, if yes, finish, otherwise, execute step S716.
In step S716, the current speed of the video is set to (T2/T).
The terminal or the background server of the target client can set the playing speed n=t2/T currently required by the video. The double-speed playing refers to playing by multiplying a certain speed on the basis of a normal playing speed. The video playing interface for setting the double speed may be as shown in fig. 8.
By way of this example, reasonable viewing or listening times may be scheduled for users in the route according to the user's route planning time: and the playing speed of the video is dynamically adjusted, when the video is longer or the episodes are more, the normal ending (or the ending of the appointed episode) of the user when the user arrives near the destination is ensured, and the integrity experience of watching the video or listening to the audio on the way of the user is improved.
