Well ,I’m working on a bittorent client and I’m trying to generate thumbnails of video files by downloading a specific piece and extracting an image from it , yet I haven’t been able to figure out a way to do so.
Thanks
I take you you mean to download specific pieces of a torrent.
First, you probably want to map the beginning of a file to a range of pieces. You can do that with the
torrent_info::map_file().Then you can select which pieces to download by
torrent_handle::prioritize_pieces(). Setting the priority of a piece to 0, means not to download it.see libtorrent documentation
