Comment (by lhastie):

 I raised the issue with the hardware provider and they assured me that the
 camera should work on Windows with '''DShow''', although they said that
 they do not use FFmpeg themselves.  I have managed to get the camera to
 stream to '''RED5''' using FFmpeg pipes.  See command below :


 {{{
 ffmpeg -y -f dshow -vcodec h264 -i video="USB Camera" -vcodec copy
 -copyinkf -f flv pipe:1 | ffmpeg -i pipe:0 -c copy -f flv
 rtmp://192.168.75.34/live/livestream
 }}}

 Although I cannot explain why this works and my command without the pipes
 doesn't.  Any insight would be appreciated.
