ffmpegのバージョンを目的のバージョンにロールバックする方法は？このシナリオではロールバックが必要ですか？
これは、armhfボードで実行されているUbuntu 16.04です。
私はffmpegを使用してウェブカメラからビデオを録画しています。プロセスは、ffmpegのバージョンで最もよく機能します。特定のバージョンにインストール/ロールバックしたい。

また、バージョンの変更が原因でエラーが発生しなかった場合や、ログがffmpegに関連する何かを示唆している場合も提案します。
間違ったバージョンをアンインストールするには、ソースファイルが必要です。 FFmpegソースフォルダーに移動し、次のコマンドを使用します。
Sudo make uninstall
それはあなたが必要としないFFmpegバージョンをアンインストールします。
