Somewhat related to this question: [Convert audio files to mp3 using ffmpeg](https://stackoverflow.com/questions/3255674/convert-audio-files-to-mp3-using-ffmpeg)

I want to execute a command in one line using piping in BASH. 

What I am trying to do is this:

```
echo "Hello" | somecommand | ffmpeg -i _____ -f mp2 output.mp3 

```

Where the `_____` is the output of `somecommand`. Is there any way to achieve this?
