Re: [Discuss-gnuradio] Dynamically changing input index of Selector block.

[Marcus Müller]

Problem being is that as soon as the head block signals "done", the flowgraph might come to a halt, effectively breaking the skip head subgraph;
how many samples are still produced after head is done depends on timing and buffer size...
I think that's why Mike recommended the "M in N", so you only have one runtime-limiting block in your flowgraph.

Greetings,
Marcus

Instead of using the "Head" block, the "Keep M in N" block should do the
trick.

You know your requirements well, let's pick whichever suits you best.
