[FFmpeg-user] filter_complex > apad and -shortest

[Jon bae]

Hello!

Is there a way to apply filter_complex with video filter + audio filter *apad
*and on top using -shortest in command line command?

When I run this:

*ffmpeg -i input.mp4 -filter_complex "[0:v]null;[0:a]apad,anull" -shortest
-f null -*

It end up in endless encoding...
