Combine Audio and Video with ffmpeg
We have audio. We have video. We appreciate each of those media on their own but you can create an awesome work of art if you combine the two. After all, how could you watch a sports highlight video without setting the visuals to some obscure techno track? Blasphemy.
My favorite A/V utility, ffmpeg, allows you to merge an audio file and a video file into one brilliant piece of art:
ffmpeg -i video.mp4 -i audio.m4a -c:v copy -c:a copy output.mp4
You can even use an animated GIF for the video piece:
ffmpeg -i video.gif -i audio.m4a -c:v copy -c:a copy output.mp4
Banter aside, there are many good cases for combining an audio track with a video track, many examples being seen on YouTube. Happy media creation!
