Video Test Source Filter

  • Article

On MSDN Code Gallery, I have posted a DirectSow source filter that generates video in various formats (RGB and YUV). Originally I wrote this filter in order to pass test video content to the EVR. You can configure the format, including interlacing and PAR, and it has a property page for use with GraphEdit.

    You can post it here and I'll see if I can answer it, or you can post it to the Media Foundation programming forum: http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=387&SiteID=1

    Hello. Thank you for answering. You'll already have answered my Evrpresenter question on media foundation forum. Evr and media foundation is a very exciting technology for me, quality and performance are very promising. Ok, i'll have to provide my own Evrpresenter and use Hwnd in the way it will be useful for my aim. Now i know i can take this direction without any problems: i think i'm going to provide my own interface. An other question: i never used swapchain before. To draw d3d objects on to video sample surface, is this the way for ?
  • swapchain->drawsample
  • swapchain->getbuffer
  • device->setrendertarget
  • device->beginscene
  • draw d3d
  • device->endscene
  • swapchain->present

    That sounds right - but I haven't tried it.
