Says fft_length is 8192, then noutput_items could be either 8192, 16384 or 24576 etc, determined by the scheduler. If you only get noutput_items equals to 8192, that could be due to the number of input elements available is less than 16384. > However one small doubt,when we print value of noutput_items in C++ > program inside the work function ,the print statement is executed twice for > any fft_length we use. Is this correct? It should only print once the > value of noutput_items if i am right. > If the print statement is executed twice, that means the work() function is invoked twice. It could be something wrong with your code, let's show your code here.
