As myself and others have said above: decode a frame.

It is not a demuxer's job to provide info gleaned from decoding.

Either avformat should be properly separate as it (kind of) is now, and provide
info required for demuxing and muxing the containers it supports, or it should
be merged into libavcodec like Nicholas wants, and it can provide both. Doing a
little of both for random fields, and keeping them as separate libraries is just
awful, though.
