For example, in the MultiDRM vector, Representation #12 stops after 142 segments.  Duration is 4000, timescale is 1000, so this is 568 seconds into the Period.  The Period duration is 734 seconds.\r\n\r\nWe would expect there to be wvtt segments to cover the entire Period.  Instead, we request [segment 143](http://media.axprod.net/TestVectors/v6-MultiDRM/12/0143.m4s) and get an HTTP 404 error.\r\n\r\nSegments in which there is no text to display should contain a `vtte` box inside the `mdat`, and nothing else.  [Segment 1](http://media.axprod.net/TestVectors/v6-MultiDRM/12/0001.m4s), for example, does exactly that."},"comment":{"url":"https://api.github.com/repos/Axinom/dash-test-vectors/issues/comments/243403050","html_url":"https://github.com/Axinom/dash-test-vectors/issues/1#issuecomment-243403050","issue_url":"https://api.github.com/repos/Axinom/dash-test-vectors/issues/1","id":243403050,"user":{"login":"sandersaares","id":9914262,"avatar_url":"https://avatars.githubusercontent.com/u/9914262?v=3","gravatar_id":"","url":"https://api.github.com/users/sandersaares","html_url":"https://github.com/sandersaares","followers_url":"https://api.github.com/users/sandersaares/followers","following_url":"https://api.github.com/users/sandersaares/following{/other_user}","gists_url":"https://api.github.com/users/sandersaares/gists{/gist_id}","starred_url":"https://api.github.com/users/sandersaares/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/sandersaares/subscriptions","organizations_url":"https://api.github.com/users/sandersaares/orgs","repos_url":"https://api.github.com/users/sandersaares/repos","events_url":"https://api.github.com/users/sandersaares/events{/privacy}","received_events_url":"https://api.github.com/users/sandersaares/received_events","type":"User","site_admin":false},"created_at":"2016-08-30T10:50:58Z","updated_at":"2016-08-30T10:50:58Z","body":"The updated audio tracks are currently being uploaded, should be available in an hour or so.
