    I add the streams using a call to

  • Hi,

    the error i get is VFW_E_CANNOT_CONNECT.

    If i try to build the graph with GraphStudiNext, i obtain the same error while trying to connect the second input:

    The same graph with VRM9 renderer works fine.

    I read somewhere that the substreams can be only of types YUY2, AYUV or NV12; is this exact?

    someone can help?

    regards, Pascal
