これを行う目的は、私の「スマート」サムスン TV が MKV ファイルを再生しないためです。
このスレッドは、ビデオ変換の必要がないことを述べています。コンテナを変更するだけで十分かもしれません。MKV のコンテナーを MP4 に変更する方法に関する複数のスレッドを読んだ後、ここから libfdk_aac をサポートする FFMPEG をダウンロードしてコンパイルしました。次のコマンドを使用して、サンプルの MKV ファイルを変換してみました。
ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"
しかし、次のエラーが発生します（コマンドプロンプトからコピー）：
[hevc @ 0000000000308ae0] Could not find ref with POC 113

また、このコマンドを使用してみました：
ffmpeg -i input.wav -c:a libfdk_aac -b:a 128k output.mp4
しかし、これはビデオの品質を台無しにし、再生中にいくつかの悪いピクセル化されたパッチが見られるようになります.
どんな助けでも大歓迎です。
