Embodiment 1

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

[0056] The video playback control module 21 obtains the to-be-played video file from the video file library 26;

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

[0058] After receiving the query request, the video playback determining module 22 queries the preset database 27 for the playback speed information of the video file to be played;

[0059] The video playback determining module 22 finds that there is no corresponding playback speed information, and sends a request to separate the video file to be played to the video playback decoding module 23;

[0060] After receivi...

Embodiment 2

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

[0068] The video playback control module 21 obtains the to-be-played video file from the video file library 26;

[0069] The video playback control module 21 sends a query request for querying the playback speed information of the video file to be played to the video playback determining module 22;

[0070] After receiving the query request, the video playback determining module 22 queries the preset database 27 for the playback speed information of the video file to be played;

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

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

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 playback method, device and terminal. Background technique [0002] Currently, when a user uses a terminal to play a video file, the terminal usually plays the video file at a fixed playback speed. During the playback process, if the user wants to quickly watch some specific plots, or want to review some specific plots, 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 title is "fast-forward and fast-rewind processing method, device, and The playback method in the patent document of “Mobile Terminal” is used to play to improve user experience. [0003] However, the playback method disclosed in the above patent document requires the user to perform a fast forward or rewind operation during the playback process, that is, it relies on...
