To update or switch versions, run `webi ffmpeg@stable` (or `@v4.4`, `@beta`,
|
|
etc).

|
## 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.
|
|
|
|
```sh
|
|
ffmpeg -i input.m4a output.mp3
|
|
```
|

> Notes: A limitation of statically linking `glibc` is the loss of DNS
|
|
> resolution. Installing `nscd` through your package manager will fix this.
|
|
|
|
_This is relevant if using ffmpeg to relay to an RTMP server via domain name._
|
|
|
|
```sh
|
|
# for example, this will not work without `nscd` installed.
|
|
|
|
ffmpeg -re -stream_loop -1 -i "FooBar.m4v" -c copy -f flv rtmp://stream.example.com/foo/bar
|
|
```
