 I would like to use "setsar" with num:denum notation where of course the
 colon ":" must be escaped "\:".
 {{{
 >ffmpeg -f lavfi -i smptebars -vf setsar='2\:1' -f null -
 This works but throws an error:
 [Parsed_setsar_0 @ 00000199d9e2b380] [Eval @ 0000002a3e3fe8b0] Invalid
 chars ':1' at the end of expression '2:1'

 >ffmpeg -f lavfi -i smptebars -vf setsar=2\:1 -f null -
 No error but don't work as ffmpeg ignore sar and set it to 1:1.

 >ffmpeg -f lavfi -i smptebars -vf setsar=2/1 -f null -
 No error and works.
 }}}
 The question is how to set sar with num:denum notation correctly without
 getting the error. Or is that just a bug/anomalie?
 Using master build from 12. October 2022.
