Abstract: An audio control method, a system, and device, the method including displaying, by a first device, in response to a first user operation, a candidate device list, obtaining, in response the user selecting a second device from the candidate device list, an audio capability parameter of the second device indicating a hardware capability and a software capability for playing audio, determining a first audio play policy based on the audio capability parameter of the second device, obtaining second audio data by the first device by performing first processing on first audio data from a first audio application according to the first audio play policy, and sending, by the first device, the second audio data to the second device, so that second device plays the second audio data or processes the second audio data and plays processed second audio data.

Abstract: This application provides a device recommendation method and an electronic device, and relates to the terminal field. The method includes: receiving, by a first device, a first operation of enabling a first service by a user; in response to the first operation, separately obtaining, by the first device from N electronic devices, device parameters associated with the first service, where the N electronic devices and the first device are located in a same communication network; predicting, by the first device according to the device parameters, quality of service of executing the first service by each electronic device of the N electronic devices; and displaying, by the first device, a device list according to the quality of service of executing the first service by each electronic device in the N electronic devices, where the device list includes a device identifier of at least one electronic device in the N electronic devices.

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 first audio timestamp of first audio is corrected based on a first latency corresponding to the first audio, to correct a correspondence between the first audio timestamp, the first audio, and a first image. In this way, a stored correspondence between the first image and the first audio is consistent with a correspondence between a picture corresponding to the first image and a sound corresponding to the first audio, thereby implementing audio and image synchronization.

Abstract: A setting information configuration method, a terminal, and a server, belong to the field of information processing technologies, where the method includes obtaining an analysis result, displaying improper setting information of a user and a setting suggestion, receiving a setting instruction from the user according to the displayed improper setting information and the setting suggestion, and configuring local setting information according to the setting instruction.

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.
