Problems solved by technology

[0002] The existing open-source video recording tools cannot specify the maximum recording video duration, cannot specify the direction of the video in some specific situations, and there are many restrictions on video definition adjustment. During the recording process, the video is blurred due to the inability to automatically focus, and cannot follow The rotation of the mobile phone automatically adjusts the recording angle, resulting in frequent changes in the angle during the playback of the recorded video, which cannot be played normally.

Abstract

The invention discloses a video recording tool based on an Android system. The tool is used as follows: carrying out initialization setting of a video recording tool, and setting recording parametersof the video recording tool; obtaining a resolution list supported by a mobile phone camera, and selecting a maximum resolution or a moderate resolution supported by the mobile phone; starting automatic focusing to enable a video interface to keep a set resolution and starting a preview interface; monitoring the rotation change and resetting the rotation angle of the camera; setting a start buttonand a delete button to be in a non-operable state, setting a stop button to be in an operable state, initializing a timer and starting timing; when the video recording meets the requirement, stoppingrecording, and stopping timing; and after finishing of the recording, resetting the recording state and returning to the file recording path. The video recording tool has the following beneficial effects: the duration and a video direction can be specified by using mobile phone recording; adjustment of video definition and automatic focusing can be realized; and automatic rotation of a video along with the gravity induction is also realized.

Description

technical field [0001] The invention relates to a video recording tool, in particular to a video recording tool based on an Android system. Background technique [0002] The existing open-source video recording tools cannot specify the maximum recording video duration, cannot specify the direction of the video in some specific situations, and there are many restrictions on video definition adjustment. During the recording process, the video is blurred due to the inability to automatically focus, and cannot follow The rotation of the mobile phone automatically adjusts the recording angle, resulting in frequent changes in the angle during the playback of the recorded video, which cannot be played normally. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a video recording tool based on the Android system with adjustable resolution, automatic focus and following the gravity sensing rotation v...
