CentOS7でffmpegを使ってmovファイルをデコードしてmp4ファイルに変換したいと思っています。  
以下の通りコマンドを入力しましたがエラーが出て実行できません。  
何が原因で対処方法がわかりません。ffmpegのビルドオプションに何かつけなければいけないのでしょうか？

ご存知の方はご教示お願いします。

```

という結果でできませんでした。

```

    # ffmpeg -i test.mov -ac 2 test.mp4
    
```

でできるようになりました。

ffmpegでmovファイルをデコードしたい

上記コマンドは、入力ファイル(MOV形式)から抽出した「映像コーデックを単純コピー」「音声コーデックを単純コピー」し、出力ファイル(MP4形式)に多重化せよという指定です。

```

上記メッセージが示すとおり、出力に指定しているMP4メディアコンテナ形式では、映像コーデック prores （Apple ProRes 422
Proxy）をサポートしません。

* * *

単にMP4形式に変換したいだけであれば、下記コマンドで十分かと思います。この場合、一度prores 映像コーデックからデコード処理が行われ、自動的に
H.264 映像コーデックによるエンコード処理が行われます。

```

    ffmpeg -i test.mov out.mp4
    
```
