Implement BEP 53 - Selecting specific file indices for download with magnet links

[dessalines]

Here's BEP_53 on bittorrent.org.

This magnet extension introduces the concept of an optional select-only file index array in the magnet URI, so that torrent clients can automatically select specific file(s) for download after the metadata has been downloaded.

Any movement on this?

Anything?

This has been implemented in libtorrent: https://github.com/arvidn/libtorrent/issues/2572

You can test this extension out here: https://torrents-csv.ml/#/search/file/frasier%20s04e06/1

Could anybody provide some minimal example for downloading only one specific file using current version of libtorrent?

[dessalines]

What do you mean by example? A client working, or what the magnet link looks like? Here's the spec: http://www.bittorrent.org/beps/bep_0053.html

sorry, wanted to write it in libtorrent repo

Any plans to support this feature?

Working on a project that will utilize "select only" magnet links. WebTorrent seems to support this feature but qBittorrent is behind on it. Of course in qB you can do this manually before the torrent starts downloading, but it would be a lot more user-friendly if these links were supported.

Not sure if this helps at all, but this is the commit where it was added in WebTorrent. Might help whoever decides to take up this task, looks pretty simple but not simple enough for me lol

[anacrolix]

https://en.wikipedia.org/wiki/Comparison_of_BitTorrent_clients#Features_II claims that qBitTorrent supports this. It does not support it in my testing. Can anyone confirm?

@anacrolix iirc it's partially supported. It can recognize so= parameter but you can't create it.
