Thanks for the tip Nico, though I'm not sure of the complete command; 
tried a few variants of:

mencoder -of lavf -lavfopts format=mpegts -o outputfile.ts input_audio.mp3

Video stream is mandatory!

Is there a way to have it use an internally generated video stream of 
null or black ? I would prefer the newly muxed music file didn't grow 
too big by adding actual video (from some other clip) into the stream.

I see someone else was chasing similar some years back:
but they ended up using vlc instead.

Can I set the input video type to raw and read from /bin/true, false or 
/dev/random ?
