    But when i add mp3 audio file then it fails

    ffmpeg -r 1/5.544000 -i 1.png -i 1.mp3 -qscale 2 1.mp4

    Following is the error that i get :

    I have generated my key and certificate using OpenSSL :

    $ openssl req -newkey rsa:2048 -nodes -keyout domain.key -x509 -days 365 -out domain.crt
    
$ sudo cp test.crt /usr/local/share/ca-certificates/
    
$ sudo update-ca-certificates

    Can someone drop me a hint or a pointer ?
