Recording metadata has its own issues - Will try and get back to you next week with more data - I guess the ffmpeg line I am using should see any metadata coming in - right? Thanks

I got a fly with custom metadata that I can play back in simple flash player and I can see my embedded data. When I try and make a copy via ffmpeg (to fix an error) I lose the metadata. The  following is my ffmpeg command line - What am I doing wrong?

nycicjrulev02:~ oriv$ /usr/local/bin/ffmpeg -f flv -i meta09.flv -map_metadata 0 -c copy metafix09x.flv
