これにより、グローバルの設定方法に応じて、カスタム ビデオ URL を持つプレーヤーが作成され、プレまたはポストロール広告 (広告プロバイダーがサポートしている場合はモバイルも) が表示されます。独自のkalturaサーバーをホストしています。
広告付きのプレイリストを有効にする追加の機能、動画をスキップするためのボタン、および広告が失敗した場合に備えて作成したタイムアウトにより、動画を再生する前にプレーヤーが 30 秒間停止することはありません (Kaltura がこの特定のものをキャッチできないため)エラー）。
仕組み: pubads.com に対して ajax 呼び出しを行い、そこから AdVastTag を解析し、広告プロバイダーを決定して、後で設定するパラメーターを決定します。VAST および VPAID 広告を配信するすべての広告サーバーと、それをサポートするプロバイダーのモバイル広告で機能します。うまくいかないのは、DoubleClick 広告で動画を表示することです。Kaltura の例は機能しますが、動画を KMS ID (動画を管理システムにアップロード) でプレーヤーに渡しますが、動画を ID ではなく URL として渡したいと考えています。
多くの人がこれに問題を抱えているようで、Kaltura がダブルクリックでカスタム URL を再生できるようにするには、バックエンドを変更する必要があると言う人がいると聞きました。誰もが見ることができる解決策を見つけ出すのは良いことです。
mediaProxyカスタム動画 URL を に渡し、doubleclick 広告タグを に渡す方法が (理想的には) 動作するはずflashvarsです。この部分は doubleClick 広告の URL を設定します。

誰かがこれを機能させましたか？どんな助け/提案も大歓迎です。
