Answer 1

独自のRTSPクライアントを実装している場合、あなたはRFC 2326: RTSP SpecなどRFC 4566: SDP Specを読み、再読がありますか？また、あなたはWindows Media Serverと統合しているようだから、MSDNはもうひとつ良いスタート地点です。

RTSPプロトコルはセッションごとに基づいており、それぞれ固有のURLで識別されます。セッションには常に1つ以上のプレゼンテーションストリーム（オーディオ、ビデオ、字幕など）があります。プレゼンテーションストリームは、セッション自体のURLに追加される追加の "a：control = ..."接尾辞によって識別されます。

特定のコマンドはセッションレベルで動作し、他のコマンドはプレゼンテーションストリームで動作し、いくつかのコマンドはどちらかを実行します。 SETUPコマンドはプレゼンテーションストリームでのみ機能するので、セッションにアクセスしようとしているためにエラーが戻ってきます。各プレゼンテーションストリームは独自のRTPストリームになり、別々に設定する必要があります。あなたがビデオストリームをしたいのであれば、あなたの場合には、あなたが送信されなければならない
