D3D11 Errors

[Carl_P_]

Hi,

I am receiving strange d3d11 errors when decoding an h264 files with (MFX_IMPL_HARDWARE | MFX_IMPL_VIA_D3D11) together with my surface allocator. Decoder is set to low latency mode: AsyncDepth = 1

I am running Intel Media SDK 2016 R2

The first call to MFXVideoDECODE_DecodeFrameAsync always generates the following:

---> D3D11 ERROR: ID3D11DeviceContext::VideoDecoderExtension: NULL parameter specified, failing! [ EXECUTION ERROR #3145789: DECODEREXTENSION_NULLPARAM]
    
the rest of the calls do not and after a while the decoder has decoded each frame. MFXVideoDECODE_GetDecodeStat() reports no errors here only valid decoded frames.

If I change the source file from a MFX_PROFILE_AVC_BASELINE to one with a higher profile (MFX_PROFILE_AVC_HIGH) the output looks like this:

---> D3D11 ERROR: ID3D11DeviceContext::VideoDecoderExtension: NULL parameter specified, failing! [ EXECUTION ERROR #3145789: DECODEREXTENSION_NULLPARAM]
---> D3D11 ERROR: ID3D11DeviceContext::CreateVideoDecoderOutputView: Invalid array element specified! [ STATE_CREATION ERROR #3145915: CREATEVIDEODECODEROUTPUTVIEW_INVALIDARRAY]
---> D3D11 ERROR: ID3D11DeviceContext::CreateVideoDecoderOutputView: Invalid array element specified! [ STATE_CREATION ERROR #3145915: CREATEVIDEODECODEROUTPUTVIEW_INVALIDARRAY]

---> (7204) 1 frames decoded, 0 frames skipped, 0 errors, 4 frames cached

...

Am I doing something wrong here or is this normal?

Hi There,

Can you share log from system_analyzer tool located at (mediasdk/tools/analyzer) ? This will help provide us your system details. 

Does MSDK sample_decode work for you ?

Thanks,

Zachary

Hi

Here's my system log.

I am using Visual Studio 2015 update 2 and I have recompiled the libmfx dispatcher with this new toolset, to be able to link my project.

Hi Carl,

Can you verify if MSDK sample_decode with -d3d11 work for you ?

Hi Zachary,

That works : 

sample_decode.exe h264 -i track1.h264 -o track1.yuv -hw -d3d11

pretending that stream is 30fps one
pretending that aspect ratio is 1:1

I can't see if there is D3D11 errors, I guess the samples are not compiled with D3D11_CREATE_DEVICE_DEBUG

// Carl

[Jiandong_Z_Intel]

Hi Carl,

Regarding D3D11 device, you can refer to <MSDK sample>\sample_common\src\d3d11_device.cpp,

How did you used D3D11_CREATE_DEVICE_DEBUG ? I find it defined in 

 C:\Program Files (x86)\Windows Kits\8.0\Include\um\d3d11.h(14203):        D3D11_CREATE_DEVICE_DEBUG    = 0x2,

and it is not "Preprocessor Definitions".

You can also try to reproduce the issue you met in MSDK sample_decode.

Thanks,

Zachary

Hi,

Your SDK sample also generates the 

D3D11 ERROR: ID3D11DeviceContext::VideoDecoderExtension: NULL parameter specified, failing! [ EXECUTION ERROR #3145789: DECODEREXTENSION_NULLPARAM]

on the first call to the DecodeFrameAsync() (only if I add the D3D11_CREATE_DEVICE_DEBUG flag to your device creation)

Your sample does not generates the other errors.

I need some clarification regarding the surface allocator

• In my case, HW accelerated decode, does the frames have to be allocated prior to decoder initialization, ::MFXVideoDECODE_Init(session, par)?
• And I guess I need to invoke ::MFXVideoCORE_SetFrameAllocator(session, allocator) ? When?
• The ArraySize param on D3D11_TEXTURE2D_DESC, should it be set to one or request->NumFrameSuggested?

// Carl

Hi Carl,

Can you upload your changset or patches of sample_decode for reproduce this issue on you end ?

Regarding surface allocator, you can refer to sample_common\src\d3d11_allocator.cpp and mfxStatus CDecodingPipeline::CreateAllocator()

in mfxStatus CDecodingPipeline::Init(sInputParams *pParams), you can see -

    sts = CreateAllocator();
    MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, sts);

    // in case of HW accelerated decode frames must be allocated prior to decoder initialization
    sts = AllocFrames();
    MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, sts);

    sts = m_pmfxDEC->Init(&m_mfxVideoParams);

Thanks,

Zachary
