I'm making an application in which I have to generate a single video clip of a duration video, I was recommended to use the ffmpeg but I do not know if it could be created and if possible how the structure would be, since I have understood that you need a file with a structure in which to establish the path in this case videos and audio, I'm working on codeigniter with php 7, and I have managed to execute the ffmpeg to change the format of a video.
The question is the following, from a database I bring the list of the route of the videos its duration and weight, equal with the audios, the thing is how I can do to create the video with ffmpeg from this.
