CentOS - Aug 2013 - Macromedia Flash data (compressed), version 9

I've copied some files from the firefox cache.
According to file, they are Macromedia Flash data (compressed), version 9.
How do I play them locally?
I saw them from a remote site through firefox,
but I cannot seem to play them locally.
neither mplayer nor vlc seems to work.
Pointing firefox at them didn't work either.
Any ideas?
