Oops, AMAP_3D_TARGET
Posted: 13th February 2012 by Roman in Seriously, VideoTags: 3D, DirectDraw, DirectShow, mixing, renderer, Video

Internally, surface allocation comes up with the following capabilities for the surface: DDSCAPS_VIDEOMEMORY | DDSCAPS_LOCALVIDMEM | DDSCAPS_OFFSCREENPLAIN | DDSCAPS_3DDEVICE. Sadly, DirectDraw responds (might respond?) with E_NOTIMPL. While one can advance one step further by removing DDSCAPS_VIDEOMEMORY | DDSCAPS_LOCALVIDMEM, another problem is hit that you are no longer able to [...]
