Perhaps I can save you some effort.

It's a Linux cross-compile targeting Windows. I'm stuck at this step:
./cross_compile_ffmpeg.sh
which declares: "your meson version is too old 0.40.1 wanted 0.47"

I have downloaded a meson 0.54.0 tarball, but I can't get Synaptic to update my system using the 
contents of the tarball.

The problem is with Synaptic, but I hoped that someone here might help because this must be a common 
task.

Regards,
Mark.
