Video filters: Arguments are wordsplit

I have attempted to specify a simple lavfi filtergraph (1 input, 1 output) of the form

Code: Select all

filter=key1=arg1:key2=arg2
with the

Code: Select all

--video-filter
option. VLC split the arguments to the filter into words where

Code: Select all

:
was the separator, which it appeared to treat as separate filters.

I thought of several possible reasons for this:
- my shell doing some screwery (immediately ruled out by single-quoting the argument, and VLC split it, not the shell)
- my syntax being wrong, maybe VLC uses other delimiter characters?
- VLC expecting something else to be passed to this.

If any, which of these is the case, and what would be a solution?
Thank you.

VLC is using : as the separator between consecutive VLC filters.

Thanks a lot, is there a way to pass lavfi filters to VLC?
