How do you know you have gathered "all the basic information" of a transport stream? (There was a sample stream for which -probesize 2G was not enough so we increased the range for the option.) > I really need a way of speeding up these two function calls (5 > seconds is not acceptable for my needs). 5 seconds seem extremely long on current hardware.
