This sink block needs to produce an 8-bit integer from every 9 elements it
receives.
The below two commands will be useful, but unfortunately not currently
being supported on python sink block:
self.set_min_ninput_items(9)
self.set_input_multiple(9)
One workaround, if it works, will be using forecast():
def forecast(self, noutput_items, ninput_items_required):
ninput_items_required[0] = 9 * noutput_items
This elaborates why I try to customize the forecast() of a sink block.
