Comment (by johnaaronrose):
Apologies. I didn't notice the reference to
https://johnvansickle.com/ffmpeg
I've now downloaded the amd64 source from there. I then tried following
the instructions from As I said before, please tell me how to download
current FFmpeg git head ot instructions on how to do it.
I've found instructions on how to compile FFmpeg for Ubuntu at
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
However, it failed on the installation of the various packages required
for compilation of FFmpeg due to an unmet dependency:
john@JohnPC:~$ sudo apt-get update -qq && sudo apt-get -y install \

> automake \
> build-essential \

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
libsdl2-dev : Depends: libsdl2-2.0-0 (= 2.0.8+dfsg1-1ubuntu1.18.04.4) but
2.0.9+dfsg1-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.
What is the solution to that?
