what values of -probesize and -analyzeduration would you recommend ?  and in
what part of the commandline they should be added ?

-probesize and -analyzeduration are there because I am testing libx264 ang
mpeg4. ( btw for less latency would you recommend mpeg4 or h264 ?)

are the unnecessary configure flags affecting the performance ?

also, is there a good way to find out what part of the process is causing
the delay ?

and are there any buffers I can ( and should ) disable ?
