it's what I imagined

it's what libmpdemux/muxer_mpeg.c does

yes, read the above file. It receives from mencoder (and all its stream 
readers and demuxers (in this
case live libraries and demux_rtp.cpp) the audio and video streams to 
mux together,
and after having parsed them the muxer determines the timestamps and the 
other parameters

read the code :) although it's quite a mess
