To do this, I create a
mavlogfile like this:
mlog = mavutil.mavlink_connection('mylogfile.tlog')
Now I want to read the flight parameters (settings) from the .tlog . The method mavlogfile.param_fetch_all() appears to be designed only to work with a live telemetry link rather than a log. It sends a parameter request command, which obviously has no result when you are linked to a log rather than an actual aircraft.
I know the parameters are in the .tlog... how do I get them out?
