Stream muxing block to multiplex many streams into one with a specified format.
Muxes N streams together producing an output stream that contains N0 items from the first stream, N1 items from the second, etc. and repeats:
[N0, N1, N2, ..., Nm, N0, N1, ...]

) | [virtual] |
Estimate input requirements given output request.
noutput_items | number of output items to produce |
ninput_items_required | number of input items required on each input stream |
Given a request to product noutput_items
, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.

compute output items from input items
noutput_items | number of output items to write on each output stream |
ninput_items | number of input items available on each input stream |
input_items | vector of pointers to the input items, one entry per input stream |
output_items | vector of pointers to the output items, one entry per output stream |
general_work must call consume or consume_each to indicate how many items were consumed on each input stream.
Implements gr_block.
