Использование ffmpeg в Python 2.7

Я безуспешно пытался установить pyffmpeg в Python 2.7. Я нашел пакет для Python 2.6, но не могу заставить его работать. Поэтому я пытался установить пакет для 2.7. Я видел предыдущие сообщения других людей на этом сайте, но они не помогли. Есть ли у кого-нибудь опыт в этом вопросе. В конечном счете, я хочу разработать приложение wxPython, которое конвертирует видео форматы. Спасибо

Код, который я в итоге написал и который сработал для меня (очень примитивный, но он работает ....):
