There is available gnash-plugin for F7.
Well I'm allways getting frustrated when thing comes to flash-plugin. Then it's beta and not working. Then you can download it but its not for x86_64. Then its available for 64 too, but when istall it, still you need manual workaround it. Then to use it u need to disable se linux what the sh....?
Then I found gnash-plugin.

Does the same as flash-plugin, but
1. it downloads with yum -y insall gnash-plugin without adding special repos
2. it supports x86_64
3. when you install it, it really is installed and working.
4. you don't need manual workaround
5. SeLinux is active and you don't need to turn it off.
sadly that it's somehow works, but hangs up. at least on my box today. But hope they will clean the bugs and this will be best choise for F7 x86_64 if you want to watch flash and easy install.
[root@localhost ~]# rpm -qa | grep gnash
