How i can use Platform integrated ffmpeg without premission issues

well i want to implement it in my project

but after running a ffmpeg command through it -or just running it using terminal- it runs but fails to read the input files with no such file or directory error

so it looks like that the runtime has no permission to read my input files - which r in the app cache dir -

so how can i use it then :confused:

i added the extension requirement in the manifest and the app have full acce
and the the runtime branch + the “ffmpeg-full” extension r installed

btw i used flatpak run --command=ffmpeg <app-id> <command> to run the container for using ffmpeg inside of it

im a noob btw so
