Кодирование видео в Android

Помогите разобраться что не так. Во всех примерах что я нагуглил кодеку и миксеру делается просто stop и release.А у меня после этого вместо финализации вайпается все содержимое записанного файла.Думал что формат цвета фрейма не нравится, пробовал и в yuv, и в argb.Но результат все тот же ((( В общем я запутался, подскажите кому не трудно что не так.
