BDA devices (directshow) in metro apps, also what's the deal with msmpeg2vdec

    Question

  • Heh.. to quote Futurama "You've raised my hopes and dashed them quite expertly, sir!" I was all psyched up to build a metro style DVB-S/T/C/ATSC directx PVR for a moment there.

    So we have mfapi.h for video in C++ Metro apps, but what if an app needs to access to BDA TV tuners? MF has no BDA support, or is that on the roadmap?

    And also, how come MS DTV-DVD Video Decoder is crippled in the development preview (refuses to connect to h264 in filter graphs, missing a bunch of MediaTypes, mpeg-2 for instance.) Was it purely a MPEG-LA licensing issue for this developer preview build? you guys will be restoring the original mpeg2 decoder for RTM's Media Center anyway right?

    Cheers,

    - Simon

  • Simon,

     

    Thanks for your interest in using the Microsoft media stack in the context of Metro. Unfortunately at this time there are no plans to enable DVB support of any kind for the Metro stack. The media team has been focusing on other scenarios for Metro and have yet to port the BDA components to the Media Foundation platform. I honestly don't know when or if this will happen but AFAIK we won't see BDA supported in Media Foundation and thus Metro anytime soon.

     

    As far as your codec problems in DirectShow on the Windows 8 CTP; Due to 3rd party restrictions it was decided that we would not include various codecs in the developer preview. We are currently reviewing the list of codecs that we ship with the operating system. Because of this you may find that some codecs that we previously shipped will be missing when Windows 8 ships. However, it is still way too early in the Windows 8 ship cycle to be able to say what will ship and what won't.

     

    Thanks,
