Option 2 in your question looks fine to me...
I have used ffmpeg to transcode audio and video streams before to achieve
adaptive streaming.
Here is an example of an audio transcode... input is 256k mp3, output is 128k,

$ ffmpeg -i http://stream.dubstep.fm -c:a mp3 -b:a 128k -f nu

I think you need to take a little step back and learn what Unix pipes
mean. They are meant to connect the output of a process to the input of
the next one, but in your examples your commands neither consume their
input nor produce outpu
