Stream map ” matches no streams.
To ignore this, add a trailing ‘?’ to the map.
Failed to set value ‘0:a:2’ for option ‘map’: Invalid argument

I am at a loss why I cannot select the second audio stream using the above command line. Anyone see an obvious mistake ?

If I exclude the map section I get Stream 1 fine but when included it objects saying no 2 stream. I even downloaded the latest stable Windows64 build with no resolution.
NB: with a MAP used its conversion speed goes from about 3x to 0.5x which is appalling.
