 I am trying to convert a video to FLV and it comes out upside down.

 You can download the video here (300mb) - http://s3.amazonaws.com/minutes-
 media/p16uvch37d1qbc1t91a9dpn1qr81.MOV

 I've tried the following command from Mac and Linux.

 /usr/local/bin/ffmpeg -y -i p16uvch37d1qbc1t91a9dpn1qr81.MOV -f flv -ab 64
 out.flv

 Here is the output from the command.

 /usr/local/bin/ffmpeg -y -i p16uvch37d1qbc1t91a9dpn1qr81.MOV -f flv -ab 64
 out.flv
