now live in a different place.

Feel free to use either, they both work but the old one provides
more information but needs the hevc decoder

Particularly those that will be needed by the QSV decoder.
More can be added later as necessary.

That loop does the actual full decoding, so 'parse' can be misleading.

This function is independent of the decoding context, so we'll be able
to use it in the parser.
