Process media files to match profiles using ffmpeg

I needed to convert tons of media files to allow Direct Play with my Roku+Plex setup. Why Direct Play? Because the box I use a media server has a pitiful CPU (Atom), so I does not do very well with transcoding on the fly. Why not upgrade the box instead? Not all of us are rich, you know... and I can't just throw it away, can I? Couldn't you use ffmpeg directly instead? Of course, but analyzing streams to know if you have to convert anything is a pain in the ass... now multiply that by hundreds of movies, then series, then music... you get the picture.

This is just a wrapper around FFmpeg tools, such as ffmpeg and ffprobe, built in Python. It's meant to be run in a shell, so you can play with for loops and whatnot. No GUI. Ever. It did start off as a (somewhat ugly) script, but then I thought, "if this grows it could become useful..." and decided to clean it up a bit. Just a bit.

You could (not yet) set up a profile (right now there's only roku), which is basically a configuration of target attributes for each media type (codec, channels, etc), which is used when processing to convert any streams if needed. For example, by using roku, all audio will be converted to 2-channel AAC and all subtitles to SRT.

It works right now, but some important functionality is missing:

• Definition of profiles by users, probably as text files (json, yaml)
• Option to append converted streams to original ones instead of replacing them
