Abstract

The invention discloses a media playing method and a media playing device. The media playing method comprises steps that a to-be-played media file is acquired; the analyzing processing of the media file is carried out to generate a video file and an audio file; according to the time information of the media file, the video file and the audio file are played; when the playing speed of the media file is required to be adjusted, corresponding adjusting parameters are generated; according to the adjusting parameters, a preset algorithm is adopted to carrying out the processing of time-scaling without pitch-scaling of the media file, and the processed media file can be played. The corresponding adjusting parameters can be generated according concrete adjusting environment, and the special processing of time-scaling without pitch-scaling of the audio file acquired by parsing the media file according to the adjusting parameters is carried out, and therefore the original pitch is not changed during the playing of the audio file, and the playing is smoother, playing effect is improved, playing requirements in various environments are satisfied, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of multimedia, in particular to a media playing method and device. Background technique [0002] In the current technology, when playing media files, if the current playback speed needs to be adjusted, a certain sampling rate is usually used to realize the processing of video images and audio clips. At this time, not only the video images will be adjusted to the corresponding playback speed , the audio is also adjusted. In this case, the sampling of the audio will cause the audio to be distorted during playback, the pitch will also change, and the playback effect will be poor. Contents of the invention [0003] The embodiments of the present invention provide a media playing method and device, which can control the normal playing of audio when the playing speed is adjusted. [0004] The first aspect of the embodiment of the present invention provides a media playing method, including: [0005] Get the med...
