It can be helpful to understand the time duration and average datarate of a capture.
Select a captured file using FMADIO CLI show capture list ( https://docs4.fmad.io/docs/fmadiocli-configure-capture#show-capture-list )
fmadiocli "show capture list"Example output below
fmadio@fmadio100v2-228U:~$ fmadiocli "show capture list"

fmadio@fmadio100v2-228U:~$In this case we are selecting interop17_20241218_1917 as the capture file to use
Then use the utility capinfos2 to calculate the statistics. This may take a while depending on the size of the capture.
<capture name> is the name of the capture to run analysis on
sudo stream_cat --chunked <capture name> | capinfos2 -vExample output:
