Let say i have a lemmy instance, and i want my users to be able to post videos. is there any way to integrate lemmy with peertube? so whenever user upload and post a video, the video will added through my peertube under a subdomain. in other word the peertube will work as a video server for my lemmy.
Read the rules, please. Particularly rule 3.
To answer your question, no, there is not currently any way to do what you're asking.
