Slobodan Vidovic's questions

I want to add audio to my ffmpeg cli bellow

ffmpeg -framerate 25 -video_size 1920x1080 -f x11grab -i :0.0 -vf format=yuv420p http://localhost:8080/feed.ffm

When I run

mkdir ../../bin/Release_Linux/Resources

Im getting an error

$ mkdir ../../bin/Release_Linux/Resources
mkdir: cannot create directory ‘../../bin/Release_Linux/Resources’: No such file or directory

Or just

mkdir Release_Linux/Resources
mkdir: cannot create directory ‘Release_Linux/Resources’: No such file or directory
