I believe there are some conda packages that include FFPMEG binaries 
otherwise I will give instructions on how to install binaries. Anyways, was

xBlocks were special packages that were only loaded via the Studio or 
something like that, but I guess a edx admin just uses SSH/SCP to install 
things.
