So, in this case, all I'm really after is to change codecs/container formats, so I just have the script/program that calls it do the output options. It never changes, so I can hard code most of the options, but you can also set it dynamically depending on your needs.

You'll need to download the file to /tmp, and also transcode it to their. This introduces the big issue with this setup - large files will fail, plainly.

2) Run ffmpeg with the options you need
3) Upload the file to S3
