FFMPEG で DVD からの VOB ファイルの連結 (マージ) を自動化する際の問題

Question

多くの実験と調査を行った結果、変数に 2 番目の BAT ファイルスクリプトを作成し、それを一時 BAT ファイルとして保存する BAT ファイルスクリプトを作成することが最善の方法であることがわかりました。作成された BAT ファイルは、必要な DVD タイトルセットとタイトルセット内の検出されたファイル数に基づいて、カスタム作成された "concat: " パラメーターを使用して作成できます。唯一の難点は、パイプ (|) 文字を含む変数に文字列を作成することがほぼ不可能であることです。ビルド中に '@' 文字を置き換えてこの問題を解決し、後でオープンソースのファイル検索および置換ユーティリティを使用して '@' インスタンスを "|" に変更しました。問題なく動作します。注: Windows 10 と、2020 年 6 月にダウンロードおよびインストールされた FFMPEG バージョン git-2020-06-26-7447045 を使用しています。以下は私が作成したコメント付きのバッチファイルです。同様のことをしたい場合は、ここから始めることができます。改善の余地があることはわかっていますが、うまく機能しています (常に良いスタートです)。
