Please don't reply off-list, this can be useful for others.

Well the input layer already take care of parsing commands, so generally
their is no need to process them before.

The read function should fill the buffer and return the number of bytes
read, or some error code.

I'm not sure i got what you want to do, but here is how one could implement
controlling mplayer via tcp:

At init:
 * Create the listening socket and turn it non-blocking.
 * Register the listening socket with select enabled.

Listening socket read:
 * Accept the incomming connection.
 * Register the new socket as command input with select enabled.
 * Return MP_INPUT_NOTHING.

Basically that's it, a full solution would need a bit more code to handle
closing client sockets, etc but this alone should already work.
