[FFmpeg-user] updating ffmpeg without git

[florian.hesse at rbb-online.de]

Hello,

i would like to update my selfcompiled ffmpeg which is running on centos.
i followed the compiling guide from wiki. 
Problem is i can't use git pull because git its blocked in our main 
firewall.
What else can i do to just update my existing ffmpeg installation?
And would it be possible to update with a different configuration? I don't 
want librtmp anymore. 

Big thanks and best regards,
Florian

This is how i compiled ffmpeg:
