私はphpでffmpegの最新バージョンでビデオファイルを変換しています:
exec("ffmpeg -y -i capture.wmv capture.mp4 2>&1", $output);
var_dump($output);
結果は次のとおりです。

HTML5 を使用して Web で再生するための標準の mp4 ファイルが必要です。どこに問題があるのでしょうか? コーデックスがインストールされていませんか? または、コンソールコマンドに何か問題がありますか?
編集:静的ビルドを使用した後、wmvをmp4に変換しようとします
exec("/www/htdocs/xxxx/video/ffmpeg -y -i capture.wmv capture.mp4 2>&1", $output);
結果ファイルのサイズは数バイトのみです。これが出力です。
