ffmpeg in flatpak runtime (42) always shows "Unable to find a suitable output format" error
That Issue Was there since 3.24, 40 and still in 42 runtime,
actually im not sure what causes it in the first place
the ffmpeg starts but always ends up with "Unable to find a suitable output format" Error
the app has full access to the inputs and output folders btw and that "ffmpeg-full" extension is added
also tried running the command through an app that uses freedesktop.platform like Blender flatpak with flatpak run --command=bash org.blender.Blender
then ffmpeg -i x.mp4 -i xx.webm -c:v copy -c:a aac output.mp4
and it worked, and it works with the standard distro ffmpeg too
but running it through apps that uses gnome.platform causes that error above
if someone at least can reproduce pls tell :\
thanks
