look, if your connection can transmit at 500kbit/sec and you set max rate
500 and bitrate somewhat lower and libavcodec chooses lets say qp=20 that
means libavcodec cannot encode the images within the bitrate at a lower qp
if you force qp=5 your stream will end up needing maybe 5000kbit/sec and you
will not recognize any faces because you will not see anything simply
because your network is too slow
what VideoQMin=Max=3 is saying is like
i want the 3rd best car
while VideoBitRateRange is saying i want the best car
which i can afford with the money i have available
(i dont need to mention that you wont get the 3rd best car if you dont pay

I do not agree with what you have to say, but I'll defend to the death your
right to say it. -- Voltaire
