these patches are a reworked version of the patchset for VC-1 hardware decoding i posted a few weeks ago.
I addressed the concerns from Gwenole, and made the patch far less intrusive.
This patch should have zero impact on progressive decoding, and only add a new code path for field-interlaced content.
The first patch actually implements the decoding, and has been tested on NVIDIA and AMD hardware, however only with DXVA2 on Windows, i do not have access to a VA-API setup, therefor i consider this patchset a RFC until someone can report how it works on VA-API, if at all.
The second patch moves a check which disables decoding of VC-1 interlaced b-frames only in software mode, and allows it in hardware mode. Decoding frame-interlaced content in hardware should already work properly without the first patch, so the patch is in theory stand-alone.
