I am on MacOS and have had mpv installed and working for a long time.

When I run cthulhu, it spits out an error indicating I do not have mpv installed.

note: In actual fact I have mpv and a MacOS fork of mpv that basically makes mpv a gui app on a mac. Both work perfectly.

Thanks for this tool, I was actively looking for exactly that some weeks ago, glad to find it on r/commandline today!

In Stremio, a GUI application that does similar things, Torrentio is a major source for torrents and seems to simply be the best for most movies or TV shows in terms of seeds and leechers, at least for 4K. Would it be feasible to expand cthulhu so that it can fetch magnets from Torrentio too (and possibly others in the future)?

Currently cthulhu automatically uses peerflix -a, which downloads all files. It is a problem for TV shows whose episodes are all bundled into the same torrent. peerflix -l seems to cover exactly that case (although it doesn't allow multi-selection, unfortunately), and same with webtorrent -s (a little bit less convenient). Wouldn't it make sense to make an option (and perhaps use -a as default) so that users can use -l/-s instead and decide which episode to stream when several are bundled together?

Ideally there could be a prompt asking whether to download all files or just one after a torrent has been selected, because the user can't know in advance which torrents would be available. Specifying the option when executing cthulhu would skip that prompt.

This is a very minor PR, but I did those changes locally and thought you could decide if you want them or not. No hard feelings if not, and sorry if you don't accept PR.

Ideally I would have liked adding a way to fetch the 20 previous or next results, but I'm not skilled in Python and was not sure how to do that (maybe enclose everything in a function and increment display_count by ±20?).

Other things I noticed:

• peerflix dependency check could be useful (after selecting a torrent, so that one can still use cthulhu to print magnets. Could be extended to webtorrent as an optional dependency if it is added as a fallback in the future.
• requests dependency check would be useful too.
• mpv and vlc dependency checks should not be hardcoded paths, because this will not work on distributions like GNU Guix or other distributions where those binaries would be installed with the distro-agnostic Guix package manager. Same issue of course with peerflix whose path will depend on the Node version, or with locally compiled mpv which would likely end up in ~/.local/bin/. Answers here may solve the issue by checking executables in $PATH instead of hardcoded paths, which would also allow checking whether peerflix is installed regardless of the Node version.
• Line 79: should it not be if 'no-clean' not in parsed_args? The way I understand it right now, it seems to delete the temporary folder if --no-clean is supplied.

Module requests not include in standard library. May be checking will be helpful.

try:
    import requests
except ImportError:
    print('error: requests is not installed (hint: pip install requests)')
    exit()

Refactored code to allow for adding new sources. They can be added as new classes and must contain get_responses(), parse_responses(), and get_magnet_link() functions.

I also removed filter flags since they are not source-agnostic, but I might re-add them later.

Sources can be selected using --source or -s flags.

Usage: cthulhu --source <source> [other options] [query]

Current available sources:

• 1337x (default)
• Nyaa

See this example where I could find Better Call Saul S06E01 with an older version of cthulhu, but it would fail when entering the ID, and after update S06E01 is not found anymore:
