[Discuss-gnuradio] Big vector problem |

Hi all
I have a problem with a big vector. The input/output of my entity is
like:
: gr_block ("sub_channel_vff",
gr_make_io_signature2 (2, 2, sizeof (float)*3072, sizeof
(char)),
gr_make_io_signature2 (1, 2, sizeof (float)*5376))
And my forecast is like:
ninput_items_required[i] = 76/4;
The problem is that one input Frame has a size about 76*3072= 233472
values and I cut four parts (at different positions) of size 5376 out of
it.
If I run the simulation I get an error:
.....is requesting more input data than we can provide.
ninput_items_required = 19
max_possible_items_available = 4....
If I reduce the ninput_items_required value the simulation works, but
the value reflectes not the truth and in the gr_block file is written:
"The estimate doesn't have to be exact, but should be close". Knows
anybody a solution or a detour to work with this big vectors?
Any idea? Any help will be appreciated
Thanks
Michael
