E Possible with AmigaOS 4.1FE Open a listening port ?

It is possible to put with the basic AmigaOS 4.1FE system
open a door to listen?
If yes, how do you do it ?

Thank you

or can I use third-party programs that work and are updated for 4.1FE ?

Ok
I was able to get YouTube-DL with FFPlay to work directly within winuae using Odyssey
Now any video I select with Odyssey through the browser is shown in Windows using FFPlay.
Of course now I have to work on the right codecs etc.

Now what I'd like to do is get exactly the opposite

here a small sample video:

any suggestion would be really very nice, to make a script that connects the Odyssey player to windows FFPlay

the YT.bat is this:

@ youtube-dl "% 1" -o - | ffmpeg -protocol_whitelist file, http, https, tcp, tls -movflags + frag_keyframe + separate_moof + omit_tfhd_offset + empty_moov output.mp4 -y -i pipe: -vcodec libx264 -acodec mp2 -f mpegts pipe: | ffplay C: \ WebOne / output.mp4

clearly now it works I have to put everything together and find some ideal solution for winuae.

the important thing is that now ffplay talks with Odyssey
