I've searched all around the web on how to download torrent files via python. The only thing I've managed to find was libtorrent, the problem with it, is that there is no clear documentation.
My initial goal is at least to connect the stream while it's downloading, to a cv2 window, to stream it.
I've managed to do it with youtube, and to transfer the mp4 file to the window, and to stream it (using Pyfy), is there a way to do it with python?
or I'm going too far, and it's possible to download the torrent content using requests or something?
BitTorrent isn't like HTTP. Files are downloaded and uploaded out of order. Files need to be saved to disk, partly to be able to upload it later, and partly because files (generally) aren't useful until the whole file has been downloaded. The files are reconstructed on disk.
If you want to stream content from a torrent, you have to do some extra steps yourself.
libtorrent has
set_piece_deadline()(docs) to indicate that you want a piece soon, it will affect the piece picker to prioritize that piece. You can also set a flag (alert_when_available) to indicate that you want a notification (alert) when the data is available, along with the buffer.
