I also saw videoCapture() but I couldn't understand how to set the renderer to show only a frame.\r\n\r\nThank you,\r\nMario"},"comment":{"url":"https://api.github.com/repos/wang-bin/QtAV/issues/comments/167698214","html_url":"https://github.com/wang-bin/QtAV/issues/558#issuecomment-167698214","issue_url":"https://api.github.com/repos/wang-bin/QtAV/issues/558","id":167698214,"user":{"login":"wang-bin","id":785206,"avatar_url":"https://avatars.githubusercontent.com/u/785206?v=3","gravatar_id":"","url":"https://api.github.com/users/wang-bin","html_url":"https://github.com/wang-bin","followers_url":"https://api.github.com/users/wang-bin/followers","following_url":"https://api.github.com/users/wang-bin/following{/other_user}","gists_url":"https://api.github.com/users/wang-bin/gists{/gist_id}","starred_url":"https://api.github.com/users/wang-bin/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/wang-bin/subscriptions","organizations_url":"https://api.github.com/users/wang-bin/orgs","repos_url":"https://api.github.com/users/wang-bin/repos","events_url":"https://api.github.com/users/wang-bin/events{/privacy}","received_events_url":"https://api.github.com/users/wang-bin/received_events","type":"User","site_admin":false},"created_at":"2015-12-29T01:58:43Z","updated_at":"2015-12-29T01:58:43Z","body":"No API now.
