How to embed command line tools in a Gambas app for AppImages ?

[Claus Dietrich <claus.dietrich@xxxxxxxxxx>]

Hi

I developed a multimedia app based of ffmpeg, which I call with Gambas 
shell commands. As I don't want the AppImage to depend on an installed 
ffmpeg on the user platform, I embedded ffmpeg in the project by adding 
a dependency in the installer dialogue. My question: How can I use the 
embedded ffmpeg, because the shell command always uses the ffpmeg tools 
installed on the host platform - not the embedded one. Do I have to 
modify an environment variable? If so, which one and how? Do I also have 
to consider whether the app is executed in development or runtime mode? 
Is it feasible at all?

Best regards

Claus
