Hmm, having checked “Download first and last pieces first” usually fixes that. e.g. a .mp4 with its moov atom at the end of the file won’t stream unless you make sure to download the last part of the file starting out. Just curious which media file type are you referring to that won’t stream regardless of having the first/last pieces downloaded?
But either way OP using Stremio + torrentio won’t fix that, that’s just another torrent client doing a torrent stream. If it won’t play mid-stream via qBittorrent it won’t play mid-stream in torrentio either.
Yes, that’s why qBittorrent’s “Download first and last pieces first” option exists. You’ll be able to stream that .mp4 with its moov atom at the end of the file as long as you download that last piece during the beginning of the download. In some ways that makes qBittorrent a better streamer for .mp4 files vs other methods.
Maybe the other commenter is referring to some other media file type that can’t be streamed.
EDIT - Haven’t checked but am guessing torrentio also downloads first/last pieces first otherwise it’d be a terrible torrent streamer.
