Hi,
I have the same problem. I have already taken a look at gr_simple_framer,
but code seems slightly complicated. I would appreciate any
explanations/comments on how to code different input and output rates.
In the block I am coding the number of input items for an output item isn't
constant. How can I handle this?
Thanks,
Irene
