This property supports file types that support media chunk alignment, such as QuickTime Movie files. The default value is 0, which means that the input chooses an appropriate default value. A value of 1 indicates not to use padding to achieve a particular chunk alignment. It’s an error to set a negative value for chunk alignment.
You can’t set this value after writing starts.
