Detailed Description
As shown in fig. 1, the variable speed playing method based on double speed playing of the present invention includes:
the method comprises the following steps that a user enters a double-speed playing mode through a long-press playing screen in the process of using mobile equipment to request a video; and releasing the screen, exiting the double-speed playing mode and entering a normal playing mode.
As shown in fig. 2, in the process of requesting a video by using the mobile device, after entering the double-speed playing mode by long-pressing the playing screen, the user switches the double-speed rate by left and right gestures in the long-pressing state. Specifically, if the user needs to view the video content in an accelerated manner for a long time, the user can slide by a right gesture in an accelerated manner to switch to a higher-speed-rate playing mode; if some users feel that the default multiple speed is too fast, the user can slide to the left by gestures when pressing the acceleration button for a long time, and the user switches to a lower multiple speed playing mode. The mode meets the requirement that users need to accelerate watching on partial plots, and also meets the requirement of browsing partial plots more quickly.
As shown in fig. 3, the present invention adopts a floating menu to start and stop a multiple speed play mode and selects a required multiple speed rate, so as to facilitate the user to browse the play in the whole play. When a user uses the mobile equipment to request video, if the whole video needs to be browsed at double speed, the user only needs to open the pop-up floating layer to open the corresponding double speed, and then the whole video can be played at the corresponding double speed
The method of the present invention further comprises dynamically adjusting the player preload time according to the speed doubling rate. In the process of double-speed playing, when the current network speed cannot meet the preloading requirement, the client sends a card heartbeat to the server and applies for higher bandwidth; and the server sends a video playing stream address with higher bandwidth according to the pause heartbeat and the preloading time.
The common standard definition code rate is between hundreds of bps to Mbps, hundreds of thousands of videos are played on line simultaneously, and consumed bandwidth is huge. How to save bandwidth and guarantee the quality of the service user, need to adjust the preloading time of the video dynamically at first, if users press and enter the playing mode of the multiple speed for a long time, the player of the customer end needs to load more preloading data than under the ordinary mode at this moment, if users release the playing screen and push out the playing mode of the multiple speed, the player of the customer end can preload the data according to the ordinary mode at this moment; secondly, if the current network speed does not meet the preloading requirement under the double speed, the client sends a card heartbeat report to the video server and applies for a higher bandwidth, the application bandwidth is determined by the frequency of the card heartbeat, and the specific process is shown in fig. 4 and fig. 5.
The invention relates to a variable speed playing system based on double speed playing, which comprises:
and (4) playing a screen: in the process of video on demand, the method is used for entering a double-speed playing mode by long pressing a playing screen, and releasing the screen to exit the double-speed playing mode; after the long-press playing screen enters a speed-multiplying playing mode, the speed-multiplying rate is switched through left and right gestures in a long-press state.
The variable speed playing system based on the double speed playing further comprises a floating layer menu: for entering a double speed play mode and selecting a double speed rate.
The variable speed playing system based on the double speed playing further comprises a preloading time adjusting unit: for dynamically adjusting the player preload time according to the multiple speed rate.
In the variable-speed playing system based on the multiple speed playing, when the current network speed can not meet the preloading requirement, the client sends a card pause heartbeat to the server and applies for higher bandwidth; and the server sends a video playing stream address with higher bandwidth according to the pause heartbeat and the preloading time.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
