You want a 1488375 sample per second interleaved uint8 stream.
This GNU Radio flow graph generates a playable IQ file from my Pluto SDR.

Correct, the input sample rate needs to be exactly 1488375. A decimation factor of 92 will give you 217391 instead, which is way off. Also, I believe the HackRF produces signed 8-bit samples, whereas RTL-SDR tools (including nrsc5) use unsigned 8-bit.

In case it's any more convenient for your use case, nrsc5's API (accessible from C or Python) has an nrsc5_pipe_samples_cs16
function that accepts signed 16-bit complex samples at 1488375/2 samples per second (i.e. half the rate that the command line tool uses).
from nrsc5.
Also, the Python command-line tool (cli.py) has an --iq-input-format
option which allows you to choose between cu8
and cs16
formats. The sample rates are as above.
