Only see one layer when composited 2 layers with mfxExtVPPComposite

[Blues_W_]

hi, all,

     I am test vpp composite filter mfxExtVPPComposite  in intel MSDK. I have 2 input streams, both are 1920x1080. The render target is 1920x1088.  I want to scale down  these two inputs stream and put it into rende rtarget with background color. 1st stream downscale from 1920x1080 to DstXYWH (0, 0, 1920, 640),  2nd downscale from 920x1080 to DstXYWH (64,64, 640, 480).  I setup related MFX_EXTBUFF_VPP_COMPOSITE and mfxExtVPPComposite struct.   The result I got not as my expected, I only got an output which from 1st stream with resolution 1920x1088. I didn't see the background color and the second steams in output frame.  Does anyone tell me where I am wrong?

   The code is based on msdk sample "mediasdk-tutorials-0.0.3\simple_4_vpp_resize_denoise" and my logic is in simple_vpp.cpp . Cmd option I used to run this sample  is "-hw -g 1920x1080 in.nv12 out.nv12".

    Thanks a lot.

Hello there, thanks for your question. I am trying to reproduce your issue and will keep you posted. In the meantime, can you send what is the status returned by the following piece of code in simple_vpp.cpp? 

    // Initialize Media SDK VPP
    sts = mfxVPP.Init(&VPPParams);

Can you also please provide details on your system (from running mediasdk_system_analyzer_<arch>.exe from tools/ in mediasdk install folder)?

Thanks.

Hello, SRAVANTHI K:

      The return values of

          sts = mfxVPP.Init(&VPPParams);

        is MFX_WRN_FILTER_SKIPPED；

Here is the info from my system, hope it can help you to reproduce the issue:

Hello there, thanks for your quick response. According to your analyzer report, the host machine has Windows OS on it. Currently, composition is supported only in Linux version of Media SDK and you can refer to sample_vpp as an example for the correct usage. I understand this may be an inconvenience for you - I will keep you posted on any developments.

Thank SRAVANTHIK for the clarification. By the way, do Intel MSDK have a plan to support VPP composition filter on the  version for Windows ? 

Thanks

[Sravanthi_K_Intel]

Hello there, yes, we do have plans to support the VPP Composition on Windows, and will update when it is. Stay tuned.
