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?
