Calling blocks directly

Hello, I am trying to write a full-program optimizer for GNURadio flow graphs in C++. For this purpose, I need to call GNURadio blocks separately inside my program. I have 2 questions: 1. How to directly feed a local vector input to a block? 2. How can I set a local array as the output a

[Discuss-gnuradio] PC requirements for DVB-S2 processing at a high bandwidth

Hi there! My name is Maria and I would like to make a question regarding the kind of PC characteristics which would be required to be able to process the signal in real-time (on the PC) when using the maximum bandwidth available on the USRP X-series. The scenario would be the following one

[Discuss-gnuradio] DVB-S2 for Windows

Hi all! My name is Maria and I am a new GNU radio user so I still need to learn quite a lot about it. I am writing this email as I need to emulate a DVB-S2 platform on a Windows machine so I wanted to ask if the DVB-S2 implementation already available in GNU can work as well for Windows. If
