mixing streams issue with EVR

    Question

  • Hello,

    I've got issues when trying to mix several streams (avi files) with the EVR, but no problem with VMR7 or VMR9.

    If the avi files contain DV (in fact YUY2), the EVR can mix and render the streams. But if the files contain other format (rgb24, MJPEG, H264,...), the EVR fails to mix. (once again, the same things works fine with VMR9 or7).

    I add the streams using a call to 

    pGraphBuilder->AddSourceFilter(...)

    and start to render with call to

    pCaptureGraphBuilder2->RenderStream(...)

    .

    Someone can help me?

    Regards

    Pascal

  • 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
