Drupal Video Module 内で FFmpeg を使用して、IOS および Flash Player10 以降と互換性のある MP4 にファイルを生成するのに苦労しています。これまでに次のコマンドを使用しましたが、「!」で始まる変数に注意してください。はプレースホルダーであり、適切なアイテムに置き換えられます:
FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile
FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfile
上記のコマンドは、次のようなエラーを生成します。
プリセット HTML5 MP4 をレンダリングするためのコマンド実行エラー、コマンド #1:

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.
私が使用した別のコマンドは次のとおりです。
FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

上記のコマンドはファイルを正しく生成しますが、Flash Player では再生できません。私が気づいたことの 1 つは、入力ファイルも mp4 の場合に発生する可能性があることです。このコマンドは、ファイルをアップロードするユーザーに対して実行されるため、入力ファイルは任意の形式である可能性があります。
