Yes, if you remembered to pass the 'left' variable to the decode 
function correctly. See below.

Well, without having looked at the example in a bit, I am sure there is 
no problem. The reason being that you specify a maximum size for the 
decode function. It will NOT decode more than that. It MAY decode less, 
and it will do so if the frame stops before the buffer is full. So by 
filling the buffer in a loop like I suggested, __and passing the 'left' 
parameter to the decode function__ (instead of just 4096), it should 
work fine.
