Re: [Discuss-gnuradio] Stop flow graph after fixed time

[Nate Temple]

A combination of the Skip Head and Head blocks will give you the desired 
result. 

[Source] -> [Throttle] -> [Skip Head, Num Items=samp_rate*3] -> [ Head, Num 
Items=samp_rate*5 ] -> File Sink 

This will Skip 3 seconds and record 5 seconds. Within the Options block, set 
the flowgraph to be "No Gui" and "Run to completion".
