Abstract

The present disclosure relates to a method and device for synthesizing video, and belongs to the field of electronic technology. The method includes: determining the duration of the audio unit for audio collection; determining the time stamp corresponding to each collected audio unit based on the time length of the audio unit; based on the time stamp corresponding to each collected audio unit and each collected The time stamp corresponding to the image unit is used to synthesize the audio unit and the image unit to obtain synthesized video data. With the present disclosure, when the audio unit and the image unit are synthesized based on the time stamp of the audio unit and the time stamp of the image unit, there will be no phenomenon that the audio and image are out of sync.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a method and device for synthesizing video. Background technique [0002] When collecting audio, audio can be collected according to a preset frequency, and audio data of a fixed duration can be collected each time. Each audio data with a fixed duration can be regarded as an audio unit. [0003] In the terminal, a time stamp can be marked for each audio unit, so that when the audio unit and the image unit are combined, the audio unit and the image unit whose time difference is smaller than a preset time difference threshold can be combined. [0004] Whenever an audio unit is collected, the audio collection thread in the terminal marks the time stamp for the audio unit. [0005] In the process of realizing the present disclosure, the inventors found at least the following problems: [0006] When the audio collection thread is busy or other threads occupy system res...
