Logo filter on Mac OS X RC/Telnet

[tmwdevelop]

I'm developing an web app to manage vlc/vlm (I cannot use the built-in VLM web cause its not working(Lua bug) and the people that are going to use it do not want or do not know how to use command line) and i'm failing to add a logo filter through command line (considering that even macosx ui does not do that well).
I'm using VLC 3.0.6 Vetinari.
I've tried to follow those steps from Documentation through RC and nothing. Tried to replicate on telnet and nothing. I've inserted the vcodec and sfilter on transcode and it does not seems to work.
#transcode{vcodec=mp4v,vb=4096,sfilter=logo}:display
neither
#transcode{vcodec=mp4v,vb=4096,sfilter=logo}:duplicate{dst=std{access=udp,mux=ts{ttl=12},url=239.255.1.1},dst=display}
I'm trying to show it on local display.
I need telnet for the schedule tools.
What I want is just to be able to control the show/hide logo with Unix Socket, if so it is not possible, I accept suggestions of other tools.
