Well, in a ::block you can do whatever you like with your in- and output buffers. Also, forecast() is called all the time, and its behaviour can by dynamic. So, between those you should be able to figure something out. 1) Edit forecast() 2) in general_work(), check if buffer sizes work 3) produce() and consume() as required MB _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
