Abstract: A mobile device positioning method and a mobile device positioning apparatus (900) are disclosed. Perception vector elements (301 and 302) are associated with projection vector elements (303 and 304) based on horizontal positions of the perception vector elements (301 and 302) extracted from an image and horizontal positions of the projection vector elements (303 and 304) obtained through projection of vector elements in a map. In this way, when the horizontal positions of the associated perception vector elements (301 and 302) and the horizontal positions of the associated projection vector elements (303 and 304) are separately arranged in a same order, horizontal position distribution of all the arranged perception vector elements (301 and 302) is consistent with that of corresponding projection vector elements (303 and 304) in the arranged projection vector elements (303 and 304), and pose estimation is performed on a mobile device based on an association result.

Abstract: A do-not-disturb method and a terminal. The method includes: displaying, by the terminal, an interface of a first application, then, if the interface of the first application includes a media playing window, and the first application is in a media do-not-disturb mode, determining whether any first media playing in the window was triggered by a playing operation of a user. If the playing of the first media in the window was triggered by the playing operation of the user, the method includes playing the corresponding media, and if the playing of the first media in the window was not triggered by the playing operation of the user, the method includes pausing or stopping play of the corresponding media. This method can avoid automatic playing of media, to reduce resource waste, data traffic consumption, a processing load of a mobile phone, and power consumption.

Abstract: A method for selecting an audio track from an audio and video file. The method includes: selecting one or more audio tracks that support decoding from one or more audio tracks of the audio and video file; selecting an audio track matching a language from the audio tracks that support decoding; selecting an audio track whose supported audio format is an audio format with a first specification from a plurality of audio tracks; selecting an audio track having a first bit rate from the audio track whose supported audio format is the audio format with the first specification; and playing the audio and video file. The first specification of the supported audio format is higher than a second specification of the supported audio format.
