The first video playback and seeking is great. When loading another video (without reloading the page, we're working in a single-page app) playback is mostly ok but seeking shows lots of artefacts. See screenshot:\r\n![Screenshot](https://animationmentor.github.io/jsmpeg/test/issue.jpg)\r\n\r\nI've put together a test page to demonstrate the problem.\r\nhttps://animationmentor.github.io/jsmpeg/test/\r\n\r\n2 videos are included, with seek buttons. You can choose to load either and seek and it will be fine. If you then load the other video and seek the artefacts will appear.  It doesn't matter which video you choose to view first — reload the page to try it again.\r\n\r\nAny help appreciated! Thanks\r\n\r\n/cc @shanytc if you have any tips let us know!"},"comment":{"url":"https://api.github.com/repos/phoboslab/jsmpeg/issues/comments/251847458","html_url":"https://github.com/phoboslab/jsmpeg/issues/93#issuecomment-251847458","issue_url":"https://api.github.com/repos/phoboslab/jsmpeg/issues/93","id":251847458,"user":{"login":"bboyle","id":559114,"avatar_url":"https://avatars.githubusercontent.com/u/559114?v=3","gravatar_id":"","url":"https://api.github.com/users/bboyle","html_url":"https://github.com/bboyle","followers_url":"https://api.github.com/users/bboyle/followers","following_url":"https://api.github.com/users/bboyle/following{/other_user}","gists_url":"https://api.github.com/users/bboyle/gists{/gist_id}","starred_url":"https://api.github.com/users/bboyle/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/bboyle/subscriptions","organizations_url":"https://api.github.com/users/bboyle/orgs","repos_url":"https://api.github.com/users/bboyle/repos","events_url":"https://api.github.com/users/bboyle/events{/privacy}","received_events_url":"https://api.github.com/users/bboyle/received_events","type":"User","site_admin":false},"created_at":"2016-10-06T01:47:51Z","updated_at":"2016-10-06T01:47:51Z","body":"Additional test that uses `nextFrame()` and canvas context `drawImage()` for the \"Next Frame\" button (instead of `seekToFrame()`).
