Hi all, I am working on a custom block that tags a stream based on a binary file stretched into unpacked form:
(1) (2) (3) gr_file_source(repeat=false) --> gr_packed_to_unpacked(1, gr.MSB_FIRST) --> my_block I want to come up with a good way to detect in my_block whether the stream input from (2) is finished. I guess gr_file_source will return WORK_DONE first, but I don't know if/how that ripples down to my_block. Basically I want to be able to tag the last incoming sample with an end-of-burst tag, but I don't know how to do this without having advance knowledge about the size of the source file. Thanks, Sean
