Logicool c920をセットアップしています。経験豊富なAskUbuntuユーザーの助けを借りて、GUVCview、Video4 linuxコントロールパネル、QT V4L2ユーティリティテスターをここにインストールしました。東芝の内蔵Webカメラから、GUVCviewを使用して外部Webカメラに変更できます。
ただし、Googleハングアウトでビデオチャットを開始すると、組み込みのラップトップカメラがデフォルトで自動的に選択されます。常に外部カメラを使用するようにデフォルト設定を変更したいのですが、このオプションの場所が見つかりません。東芝サテライトL755でWindows 7とUbuntu 12.04 LTSを実行しています

はターミナルを試し、ビデオの下のデフォルト入力をロジクール外部カムに変更しました。まだ運がありません。「テスト」すると画像が表示されず、GUVCを開いてもラップトップのカムが表示されます。
2番目の編集:マルチメディアセレクターをターミナルにインストールした後も、ダッシュでそれを見つけることができませんでした。コマンドを実行した後の読み出しは次のとおりです。

Gstreamer-properties
端末で実行すると、マルチメディアセレクターが表示されます。デフォルトの入力を外部に変更すると、(「テスト」を押すと)外部カムの青いライトが点灯しますが、画像が表示されません。これが設定のスクリーンショットです
3番目の編集:ルートとして実行した後、sudo gstreamer-properties
デフォルトの入力をHD Webカメラ(前のスクリーンショットと同じ設定)に変更し、GUVCを開くとラップトップカメラとして開きます。SUDOを実行した後の表示は次のとおりです

ターミナルを介してそれを実行しました。数分後、スクリプトは完了し、失敗やエラーに気づきませんでした(以下にコピーを配置します)。しかし、次に実行するsudo gstreamer-properties
と、上記と同じ「利用できないプラグインをスキップしています」というメッセージが表示されました^。マルチメディアシステムセレクターのデフォルトの入力はc920 HD camに設定されていますが、GUVCを開いただけでラップトップカメラが開きます。これがsudo apt get install
