Detailed Description

template<std::size_t Dim, typename Elem>
class mf::seekable_frame_importer< Dim, Elem >

Seekable frame importer, abstract base class.

Can change position in file using seek(). Keeps track of absolute frame index (called current time). Total duration of file is known after construction.
