I am trying to use ffmpeg to defish my gopro videos on a mac.  The lens
correction is working reasonably well though eventually I'd like to have
hardware acceleration working, but first I am having a more basic problem.
When ffmpeg gets to the audio stream it complains about the audio stream.

    Error while decoding stream #0:1: Invalid argument:00:47.31

I tried a few stream mapping options but no success.  Below is the most
basic command and resulting output. I tried another MP4 file and it worked
fine.

Thanks,
Harry
