The invention relates to the field of software applications, in particular to a video composition control method and device, and a corresponding terminal. The method comprises the following steps: acquiring a plurality of source video streams; receiving a selection command of a user for image and audio control buttons configured for each source video stream, and setting the control button(s) for each source video stream; processing each source video stream according to the set control button(s) to obtain images on which composition is to be carried out and audios on which the composition is tobe carried out; and processing the images on which the composition is to be carried out and the audios on which the composition is to be carried out to obtain a composite video stream. The method anddevice and the terminal provided by the invention have the advantages that through the configuration of the image and audio control buttons for the source video streams, the user only needs to selectthe control button(s) for each video stream for selection of the images or the audios of the corresponding source video stream, and obtains the composite video stream, so that the requirements for audio switching following video switching in a simple scenario and muting of one of the source video streams or forced audio output of one of the source video streams in a complex scenario can be satisfied, higher convenience in operation is achieved, and the programming cost is reduced.
Description
technical field [0001] The present invention relates to the field of software applications, in particular to a video synthesis control method, device and corresponding terminal. Background technique [0002] With the rapid development of Internet technology, all kinds of live video broadcasts are becoming more and more popular with the audience. The traditional live broadcast of programs based on radio and television equipment is equipped with video switchers and audio mixers on site, and different operators conduct video broadcasts. Screen switching and audio signal synthesis to generate the final program signal. This solution has relatively high equipment costs and use thresholds, and is difficult to promote and use in the current Internet live broadcast industry; in the Internet live broadcast industry, it is currently mainly based on computer-based software switching Station / director software generally integrates the functions of video switching and audio tuning, and sim...
