A -shortest-video option that acts just like -shortest but ignores audio

[Florian]

Anyone who exported a final project with video+audio ready to then encode with ffmpeg, they don't want the audio to extend the last frame of video. Yet they cannot use -shortest because this would make the audio trim the video if shorter.

A good solution to that problem would be a -shortest-video option which would act exactly like -shortest but would only look at the video inputs.
Also, this is probalby extremely simple to implement since you already have -shortest

Thanks!
