What do you mean exactly by 'join'? What kind of 'multiple input 
streams'? Are they supposed to occur one after the other (i.e. join 
meaning concatenate) or simultaneously (join means muxing).

If one after the other: then some formats are can be simply 
concatenated, like MPEG-1 and MPEG-2. For some others there exist 
special tools like avijoin.

If simultaneously: then ffmpeg can already mux 1 audio and 1 video stream.
