I am not very familiar with AppImage, but the build scripts create launcher
scripts that set various environment variables relative to the location of
the launch script:
https://github.com/mltframework/mlt-scripts/blob/master/build/build-flowblade.sh#L1105
Maybe you can make a launch script and tell AppImage run that instead of
your main python script.
