I would like to share my jellyfin movies and tv shows with my friend. I was thinking about allowing only his IP address to connect to my jellyfin server.
Is it a crime? Can I be arrested for this? I do not plan on running a mega operation for hundreds of people.
Is that ok to do?
Exactly. In Poland that would be legal because it’s personal use with close circle (family, friends). It’s legal to download a copyrighted media file that’s been shared online and share it within that close circle but not share it publicly or to larger groups. So downloading a copyrighted file via torrent is still illegal because you are simultaneously sharing the file with wide audience.
The regulation roughly translates to ‘fair use’ and there need to be similar laws on other countries as well, at least for the download part. You should be free to assume that whoever put a media you see online had the right to do so (if they didn’t, they broke the law but not you by downloading). If downloading a copyrighted media file was illegal then visiting any website would be a crime because they contain media (images, videos) that our browsers automatically download in order to display them.
This does not apply to software.
