I apologize I thought I was posting in the correct forum.  Please move 
this to the correct place. Im still new to ffmpeg and all of its 
nuances.  If you could direct me to the correct list I would greatly 
appreciate it.

Right now I seem to be unable to install the rtmpdump package which is 
supposed to install the rtmp needed.  Keeps stating that it cant find 
openssl even though its installed.

Will have to keep working on it.
