Dual-View Video Playback Audio Selection Using View Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording and playback systems on mobile devices struggle with effectively managing audio playback in dual-view modes, where multiple camera views are displayed simultaneously, leading to confusion and inefficiency in selecting and playing audio for each view.
Innovation Solution
A method and device that allow users to select and play audio for specific video views through interactive controls, such as drag-and-drop or voice commands, enabling independent audio playback or mixing for each view, and utilizing microphone arrays for enhanced audio processing during dual-view recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-view mode is implemented to increase shooting flexibility, then shooting flexibility is improved, but audio playback becomes confusing and inconvenient
Solution Approach 1:
The audio playback function is segmented by view. Each video view (first video, second video) has its own independent audio track (first audio, second audio). Users can selectively play audio from specific views by interacting with view-specific controls, eliminating confusion about which audio corresponds to which view.
Solution Approach 2:
A play control element is introduced as an intermediary between the user and the audio playback system. This control includes a first play control for selecting audio from the first video view and a second play control for selecting audio from the second video view, providing clear and intuitive audio selection without confusion.
2Adaptability or versatility
If multiple audio streams are provided for multiple views, then audio selection flexibility is improved, but system complexity increases
Solution Approach 1:
The audio management system is segmented into independent components: each video view has its own audio stream and dedicated play control. This segmentation allows the system to handle multiple audio streams systematically without overwhelming complexity, as each stream is managed independently through its own control mechanism.
Solution Approach 2:
The play control elements serve multiple functions: they indicate the current audio selection state, allow users to switch between different audio streams, and provide visual feedback about which audio is currently playing. This multi-functionality reduces the need for additional separate controls, managing complexity while maintaining flexibility.

AI summary
The technical solutions of this application provide a video playing method and a device, so that in a multi-view mode, during video playback, audio corresponding to an image in a plurality of views may be selected and played based on an operation performed on a play control. In response to a user input, a video playing interface is displayed on the electronic device. The video playing interface includes a first video, a second video, a first play control, and a second play control. In response to an operation performed on the second play control, the first video and the second video are played. Audio of a video corresponding to a location of the first play control is played. The video corresponding to the location of the first play control is the first video.
