I'm afraid, it's impossible to build this version of gmf under the current ffmpeg (version git-2013-08-12), because of massive changes in api — only 0.8 version supported.

Try to build under 0.8. But anyway, the current gmf version is not production ready.

I use Go 1.0.3 and ffmpeg-0.8.10 try it again
but i get some undefined reference error
such as:

It's not a gmf build issue. There is something wrong in Your ffmpeg build. Why it references on the /usr/local path? What is the value of the --prefix parameter? Have You successfully built it?
