I can encode 720p up to 1440p with no problems whatsoever - I have yet to run into any issues when using the Intel provided sample_encode. When running the sample_encode from the SDK everything works properly. Platform: Core i7 4712HQ 2.30GHz, Intel HD 4600 (driver version 20.), Windows 10 (also has an NVidia Quadro K1100M) Product version: sample_encode.exe from Media Server 2017 R3 and ffmpeg (built from master) I'm experimenting with using the h264_qsv encoder and am experiencing 'device failure (-17)' issues under varying workloads. M_pDX11VideoDevice = m_pD3D11Device <<-ĭo you have any pointers, it would be greatly appreciated, Cheers.

However when debugging using the 'Graphics Debugging' tool, it does not like the assignments:

Next I tried the 'Graphics Debugging' console tool in Visual Studio to see what, if any objects are left open agianst the HWND. In the Close() function as recommended by Microsoft to no affect, similar to the stackoverflow thread above. I believe the issue to be related to the following thread: The error is 'CreateSwapChainForHwnd returns E_ACCESSDENIED' on a second Class and Call using the same window handle.Ī believe a DirectX resource / object has not been properly freed. However, I'm unable to create a new window handle as a work around (CCTV switching in a single HWND). It is the continuation of an existing error found on the Intel forum:įirst call into a new class succeeds, second call into a NEW class fails using the same HWND. I have an issue with the provided class d3d11_device.cpp, I have spent a couple of days trying to debug and have now surrendered.

Thank you for the Intel Media SDK samples and Tutorials, the coding is very good.
