Just to put a number on this question, the DVB-T2 transmitter uses up to 16 Megabyte buffers between blocks. I'm not sure what the absolute maximum is, but 16 Megabytes should cover most applications.

The DVB-T2 blocks use set_output_multiple() in conjunction with forecast() to allocate these large buffers.

Hello GNURadio community,

Does anyone know what is the maximum number of input items that an Out Of Tree block can consume on each input stream?

consume_each(consumed) --> what is the maximum value that the variable consumed can take?

Thank you very much.
