I got the following polite request from Stefano Sabatini:

"I'm an FFmpeg developer and I picked an old patch on ffmpeg-devel by
Giliard, check this thread:

The patch implements an input device for the Linux framebuffer.
The patch by Giliard was presumably based on the fbgrab.c code and was
using the GPL license, as fbgrab.c itself.

I ask you if you have problems at allowing the derivative code to be
licensed as LGPL rather than GPL. We believe there is not much code in
