Hello,
I'm compiling ffmpeg, frei0r, mlt and kdenlive packages for Debian unstable locally from latest git trees. The packaging is copied with minor modifications from Debian and debian-multimedia.org packages. ffmpeg, melt and kdenlive work just fine but I seem to be missing a number of plugins, like RGB color adjustments in kdenlive GUI. How should I go and debug this? Has there been some major plugin or binary name or path changes in last few months, which my perhaps stale packaging files are missing?

I tried re-doing the packaging: cleaning frei0r, mlt, kdenlive git trees and copying latest dmo or debian unstable packaging on top. But still some plugins were not found, especially the RGB adjustment. So I installed frei0r, mlt and kdenlive with checkinstall instead, so now they work and plugins are there. I'll stick with this checkinstall approach then, which just shoves make install targets to .deb packages.
