Добавить звуковую дорожку для jpeg в видео в JMF (JpegImagesToMovie.java)

Я сохраняю видео в формате JPEG в файлы, затем отправляю вектор со всеми именами файлов и могу создать новое видео. Теперь я хочу добавить звук. Мне, вероятно, понадобится звук и с динамиков, и с микрофона, но моя основная проблема заключается в том, как сохранить их в видеофайл. У меня такое чувство, что я могу понять, как их схватить.

Я кодирую видео следующим кодом:
