well, just remaking cinelerra put resulting binary in bin, and plugins and
stuff should already be there from previous build.

BUT in this case we need to rebuild ffmpeg itself, not just our interface
to it.

rm -rf thirdparty/ffmpeg-7.0

rm thirdparty/build/ffmpeg.*

make

or you can do full rebuild just in case, but do not forgot to save profiles
you  worked on for so many days ...
