How to Use FFmpeg with Deno (No Installation Required)

Deno engineers can use FFmpeg for video processing without installation by using Deno's Command API or third-party libraries like @ffmpeg/ffmpeg. However, native FFmpeg is 10-20x faster and only works with --allow-run and file system permissions. An alternative is to use a cloud-based FFmpeg service like ffmpeg-micro.com, which works everywhere Deno runs, including Deno Deploy.
