Sorry, I slightly misread the ticket yesterday.
Again, please feel free to reopen the ticket if you believe that above
message is unclear!
Stream 0x75 is indeed a mono stream but FFmpeg correctly warns that it may
have incorrectly read the stream properties.
The following command line allows to correctly detect the mono stream (and
allows the automatic stream selection for -acodec copy to choose the
channel that you seem to prefer in your output file for this specific
input file).
