Embodiment 1

[0055] Such as image 3 As shown, assuming that the video playback determination module 22 determines that the playback speed information of the video file to be played is not in the preset database, then the interactive process between the above-mentioned modules is as follows:

[0056] Video playback control module 21 obtains the video file to be played from the video file storehouse 26;

[0057] The video play control module 21 sends the query request of querying the play speed information of the video file to be played to the video play determining module 22;

[0058] After the video play determination module 22 receives the query request, it inquires about the playback speed information of the video file to be played from the preset database 27;

[0059] The video playback determination module 22 inquires out that there is no corresponding playback speed information, and sends a request for separating the video file to be played to the video playback decoding module 23; ...

Embodiment 2

[0067] Such as Figure 4 As shown, assuming that the video playback determination module 22 determines that the playback speed information of the video file to be played is in the preset database, then the interactive process between the above-mentioned modules is as follows:

[0068] Video playback control module 21 obtains the video file to be played from the video file storehouse 26;

[0069] The video play control module 21 sends the query request of querying the play speed information of the video file to be played to the video play determination module 22;

[0070] After the video play determination module 22 receives the query request, it inquires about the playback speed information of the video file to be played from the preset database 27;

[0071] The video playback determination module 22 queries the corresponding playback speed information, and returns to the video playback control module 21;

[0072] The video play control module 21 plays the video file to be p...

Abstract

The embodiment of the invention provides an adaptive video playing method, device and terminal. The method comprises the following steps: determining whether the playing speed information of an obtained video file to be played is stored in a preset database or not; if the playing speed information of the obtained video file to be played is not stored in the preset database, separating video data and audio data in the video file to be played, generating the playing speed information of the video file to be played according to the initial playing speed of the separated audio data and the playing speed corresponding to a preset audio data frequency bandwidth width range determined by a user, and storing the playing speed information of the video file to be played in the preset database; and according to the generated playing speed information, playing the video file to be played. When the above flow is executed on a terminal, the terminal automatically regulates the playing speed of the video file according to the demands of the user before the video file is played, subsequently, the terminal only needs to play according to the regulated playing speed, the user does not need to manually carry out a fast-forward or fast-backward operation, and the method is convenient in operation and improves user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an adaptive video playing method, device and terminal. Background technique [0002] At present, when a user uses a terminal to play a video file, the terminal usually plays the video file at a fixed playback speed. The fast forward or fast rewind operation is usually performed manually. In this case, for the terminal, the existing application number is 201110002610.1, and the invention name is "Fast forward and fast rewind processing method, device and The playback method in the patent file of "Mobile Terminal" is played to improve user experience. [0003] However, the playback method disclosed in the above-mentioned patent document requires the user to perform fast forward or fast rewind operations during the playback process, that is, it depends on the user's manual adjustment, which makes the user's operation inconvenient and the user experience is still low....
