One could use the ast_smoother interface.  It was designed specifically
to take frames of variant sizes and produce frames of a single expected
size, precisely what you want to do.

The basic interface is:

Initialize with ast_smoother_new(), queue input frames with
ast_smoother_feed(), get output frames with ast_smoother_read(),
and when you're done, free the structure with ast_smoother_free().
