+tagline: |
+  FFmpeg: A complete, cross-platform solution to record, convert and stream audio and video.
+---
+
+## Updating `ffmpeg`
+
+```bash
+webi ffmpeg@stable
+```
+
+Disclaimer: ffmpeg does not provide official binaries, so
+<https://github.com/eugeneware/ffmpeg-static> is used.
+
+## Cheat Sheet
+
+> FFmpeg is useful for converting between various audio, video, and image
+> formats.
+
+Many simple conversions can be auto-detected by file extension and the options
+that produce the most similar quality by default.
+
+```bash
+ffmpeg -i input.m4a output.mp3
+```
