'video/x-raw, width=1280, height=720' ! queue ! imxipuvideosink use-vsync=true`\r\n\r\n  Followed by:\r\n`gst-launch-1.0 videotestsrc ! 'video/x-raw, width=880, height=720' ! queue ! imxipuvideosink use-vsync=true`\r\n\r\nThank you again!\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/Freescale/gstreamer-imx/issues/comments/125957582","html_url":"https://github.com/Freescale/gstreamer-imx/issues/49#issuecomment-125957582","issue_url":"https://api.github.com/repos/Freescale/gstreamer-imx/issues/49","id":125957582,"user":{"login":"dv1","id":335064,"avatar_url":"https://avatars.githubusercontent.com/u/335064?v=3","gravatar_id":"","url":"https://api.github.com/users/dv1","html_url":"https://github.com/dv1","followers_url":"https://api.github.com/users/dv1/followers","following_url":"https://api.github.com/users/dv1/following{/other_user}","gists_url":"https://api.github.com/users/dv1/gists{/gist_id}","starred_url":"https://api.github.com/users/dv1/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dv1/subscriptions","organizations_url":"https://api.github.com/users/dv1/orgs","repos_url":"https://api.github.com/users/dv1/repos","events_url":"https://api.github.com/users/dv1/events{/privacy}","received_events_url":"https://api.github.com/users/dv1/received_events","type":"User","site_admin":false},"created_at":"2015-07-29T13:45:50Z","updated_at":"2015-07-29T13:45:50Z","body":"No problem.
