Linux Mint：音楽の再生中に停止を防ぐ方法

簡単な質問があります。音楽を再生するときにコンピュータが一時停止しないようにしたいと思います。遊ぶ私のコンピュータのデスクトップアプリケーションで - スクリプトよりも優れた作業を行い、音楽アプリケーションの実行中に自分のコンピュータをアクティブにしたいと思います。開いている。私はLinux Mint 18を使用しています。

アプリごとに動作できると思いますが、一般的なCinnamonサウンドアプレット（または同様のもの）を活用してこれを行う方法があるかどうかを知りたいです。アプレットは、Spotify、Clementine、Bansheeなど、ユーザーが開いたすべての音楽アプリで再生を検出して制御できます。音楽がサウンドアプレットまたは特定のアプリケーションで再生されるかどうかをスクリプトで確認する方法はありますか？

私はこの質問を知っています：Spotifyで音楽を再生しながらMintが一時停止しないようにするしかし、受け入れられた答えは問題を解決できませんでした。それ以来、カフェインは完全に変わりました。

私が望む行動は、次の理由で有益です。

  • ユーザーがバックグラウンドで音楽アプリを開いたままにしても再生が停止しても、コンピュータは無期限にアクティブになりません。
  • ユーザーがコンピュータから離れている間に音楽を再生して音楽を再生し続けたい場合は、音楽再生を続行するために音楽プレーヤーが全画面表示されることを心配する必要はありません。
  • ユーザーはさまざまな方法でこの動作を利用できます。たとえば、寝る前に快適な音楽を20分間選択できます。 20分のプレイリストが終了すると、コンピュータは一晩中一時停止します。したがって、プレイリストの長さに合わせて睡眠時間が自動的に調整されます。

私はこの問題を解決したいのですが、このような性格のスクリプトを書いたことがないので、どこから始めるべきかわかりません。これは基本的ですが便利です。おそらくMintの機能要求であるべきです。

私も同じことで苦労しています。 pulseaudioの状態を確認するためにpactlを使用することについて議論する他の記事を見つけました。以下はリンクです：

https://superuser.com/questions/393448/Detecting-audio-playing-in-a-bash-script

私は音楽の再生中にCinnamonの電源設定で一時停止タイムアウトをNeverに変更し、音楽が停止したときに再起動する非常に簡単なスクリプトを作成しようとしています。これはスクリプトを書くための私の最初の実際の試みなので、改善できる場合は自由に感じてください。しかし、シナモンにのみ効果があるかもしれません。

ソフトウェアマネージャからCaffeineアプリをダウンロードしてインストールします。次に、デスクトップパネルにCaffeine Indicatorをインストールします。その後、レジャー時にカフェインを有効または無効にすることを選択できます。 Linux Mint MATE 19.3でうまく動作します。
