Im modifying tv.c to properly handle audio.  Im having all sorts of troubles
getting the audio encoders to act properly.  For example if I say -oac copy it
appears to not actually ever do anything, because mux_a->timer never
increments.  What causes this to increment in other muxers cases?

All im really doing is creating ds_add_packets()'s, but im not sure what to do
with the members of the structure other than the buffer.  pts Im guessing is a
frame counter, but not sure how its really used to set it properly, same iwth
pos..
