gst-ffmpeg builds against internal copy of ffmpeg, statically. That's
why it's so big.

You need to use --with-system-ffmpeg switch to configure (or something
like that). And after that you have to make sure that configure will
find the ffmpeg YOU've built, not the one you've installed from package
manager (not sure how to do that).
But be sure to look at gst-ffmpeg/ffmpegrev to get the right versions of
ffmpeg to pull when you're going to build ffmpeg yourself. Building
gst-ffmpeg against a random external version is prohibited.
