Uzun süre araştrıdım. Adam gibi bir kaynak bulamamıştım. Cevizde birisi anlatmış. Buldum denedim ve sorunsuz çalışıyor.
İlk başta aşağıdaki ffmpeg dosyasını indirip C: içine açın

Eğer bu scripti kullanmak istemezseniz
PHP Kodu:
system('C:\\bin\\ffmpeg.exe -i C:\\1.avi C:\\1.flv');
şeklinde ffmpeg i kullanabilirsiniz..
Yazıyı güzel gördüğüm için
alıntı yaptım.
Bunlarda yaptığım bazı örnekler
Ekran görüntüsü almak
PHP Kodu:
system('C:\\bin\\ffmpeg.exe -i C:\\xampp\\htdocs\\flv\\h\\xx.wmv -s 320*240 -vframes 1 -f mjpeg C:\\xampp\\htdocs\\flv\\h\\x.jpg');
wmv yi flv ye çevirmek
PHP Kodu:
system('C:\\bin\\ffmpeg.exe -i C:\\xampp\\htdocs\\flv\\h\\xx.wmv C:\\xampp\\htdocs\\flv\\h\\1.flv');
