It looks like when a graphic sink isn't visible, it doesn't run.
Is there a clean way to override this behaviour?
For some types of graphical outputs, like waterfall sinks, which show a
time series, having that waterfall
stop, simply because it isn't currently visible, is broken. If you
have
Hi,
When i
sudo make
the gnuradio, i get following error :

I need to ask two questions...
1) What is the purpose of vector sink and/or vector source in GRC. If i convert
a stream from USRP2 into a vector and connect the result to a vector sink, what
information i can have and how do i acess that vector (ploting or writing to a
file etc)..

Sorry about the code, it was generated mostly via Grc. I've cleaned it up,
should make much more sense now:

I've tried using the available DQPSK blocks as you suggested,
it needs #includeboost/bind.hpp in that file -Josh

It looks like what you want to do is outside of the scope of GRC. You
will need to create custom blocks to provide that functionality, or make
hand-written python code with wxpython.

This has been fixed recently in the git repository. It was a missing
header file include.

This was an optimization for performance. One can quickly run out of
CPU by having multiple notebook tabs with display sinks in them.

Apparently there is a problem with usrp_benchmark_sub.py …
Some basic tests for USRP operation.

Is there any kind of guide as to how gr.prefs is supposed to be used?
Is this functionality going

Hi everyone,
I am trying to implement a video player block for gnuradio, which uses
various
ffmpeg libraries. Unfortunately, I've been having difficulty linking to the
ffmpeg libraries within
the gnuradio framework.
My approach so far has been to include the libraries in the
