Is it wise to get into the area of enforcement? It's so easy to get around...

Our software uses FFmpeg, and we check for the LGPL string as a
safeguard to make sure we never ship a GPL FFmpeg build by mistake. A
side effect is that the legitimate (GPL permitted) user action of
replacing our FFmpeg binaries with their own (possibly GPLd) versions
is not supported by our application.

Seems like a mine field to me.

If the builder/distributor of FFmpeg asserts that they have a suitably
license for x264 (etc.) then let them get on with it... ?
