It's possible but is not so easy. In the last year I have posted a lot of 
questions about this but nobody has reply to me. I not know why, perhaps 
because I'm from Italy and my english is not correct or because is not a 
tipical question.
In order to grab all from ffmpeg you have two ways:
1) Using callbacks "avio_alloc_context"
2) Using "avio_open_dyn_buf" and "avio_close_dyn_buf"

After that you must know that not all format are streamable.

I don't know if these are the right ways but works for me. I have wrote a 
surveillance software with ffmpeg.
