Tada, you should have a new version of your video with the randomly chosen music looping for the duration of the video.ĭid you find this information useful? If so, consider heading over to my donation page and drop me some support.In this article we are going to look at some options and examples of how you can use FFmpeg multimedia framework to perform various conversion procedures on audio and video files. The audio stream technically never ends since it loops forever. -shortest tells FFmpeg to stop writing data to the file when the shortest stream ends, which, in this case, is our video stream.amix - combines the audio from the video and the newly loaded background music into one audio stream.The volume filter is used to adjust the volume of the music to be more "background music" appropriate
amovie=$bgm:loop=0,volume=0.03 - this loads the randomly chosen music file to make its audio stream available and with the loop argument set to 0, loops it indefinitely.I'll talk about the important parts of this FFmpeg command.We get the music file to load in using the random_music script and save it for later.The directory you want to pick the random music from.map 0:v -map "" -shortest -c:v copy "$output" Time for the FFmpeg magic: #!/usr/bin/env sh I write the output of all that to a text file for reference later, as well as using head to list that file to stdout.With the -n 1 flag, it will output only the first line I pipe that output to shuf, which randomizes the list of files.I list out of contents of that directory using find.For this, I wrote a simple script: #!/usr/bin/env sh I wanted to pick a random music file from a directory for the first part and use it later. The music I use for this is from a project called StreamBeats, you should check it out. Naturally, I turn to my weapon of choice in these cases, FFmpeg.
So recently I decided to try adding some background music to my videos so it isn't just me blathering the whole time.
