I believe this is due to that recent Twitch VODs seem to be stored in tiny chunks.(around 1MB) It would be nice if youtube-dl could get faster download speeds. This may be possible by downloading a number the chunks in parallel."},"comment":{"url":"https://api.github.com/repos/rg3/youtube-dl/issues/comments/75161076","html_url":"https://github.com/rg3/youtube-dl/issues/4772#issuecomment-75161076","issue_url":"https://api.github.com/repos/rg3/youtube-dl/issues/4772","id":75161076,"user":{"login":"csenger","id":223032,"avatar_url":"https://avatars.githubusercontent.com/u/223032?v=3","gravatar_id":"","url":"https://api.github.com/users/csenger","html_url":"https://github.com/csenger","followers_url":"https://api.github.com/users/csenger/followers","following_url":"https://api.github.com/users/csenger/following{/other_user}","gists_url":"https://api.github.com/users/csenger/gists{/gist_id}","starred_url":"https://api.github.com/users/csenger/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/csenger/subscriptions","organizations_url":"https://api.github.com/users/csenger/orgs","repos_url":"https://api.github.com/users/csenger/repos","events_url":"https://api.github.com/users/csenger/events{/privacy}","received_events_url":"https://api.github.com/users/csenger/received_events","type":"User","site_admin":false},"created_at":"2015-02-19T23:26:44Z","updated_at":"2015-02-19T23:26:44Z","body":"This might be worth a separate issue additional to a general problem with slow http connections. But regarding @Diazonium's comment, there was a change in behavior on the twitch side.\r\n\r\nSome Links to videos have the format `http://www.twitch.tv/<username>/b/<videoid>`, e.g. http://www.twitch.tv/riotgames/b/579679336 . youtube-dl downloads a bunch of flv files pretty fast.\r\n\r\n```\r\ncsenger@sympathikus:~/Videos$ youtube-dl http://www.twitch.tv/riotgames/b/579679336\r\n[twitch:video] 579679336: Downloading video info JSON\r\n[twitch:video] 579679336: Downloading video playlist JSON\r\n[download] Downloading playlist: 2014 Worlds Final - Samsung White vs. Star Horn Royal Club - 10/18/14\r\n[twitch:video] playlist 2014 Worlds Final - Samsung White vs. Star Horn Royal Club - 10/18/14: Collected 13 video ids (downloading 13 of them)\r\n[download] Downloading video 1 of 13\r\n...\r\n´´´\r\n\r\nFor other twitch users the URL format is different: `http://www.twitch.tv/<username>/v/<videoid>`, e.g.  http://www.twitch.tv/planetside2/v/3810046 .\r\nIn this case youtube-dl tries to pipe the download through avconv. Maybe to combine the best audio with the best video, but I'm not sure. This produces the verbose output in the last comment and is pretty slow. Also aborted downloads can not be resumed.\r\n\r\n"}}
