H.264 hardware encoding doesn't work on Windows Server 2008
Hi,
I failed to set up H.264 encoder accelerated by Intel hardware, on platform as follows:
CPU: Intel Core i3-2120 (with Intel HD Graphics 2000)
OS: Microsoft Windows Server 2008 R2 64-bit
After searching and downloading from Intel download center website, none of the following drivers works:
(1) Intel® HD Graphics Driver for Windows Vista* 64 (exe) https://downloadcenter.intel.com/download/21414/Intel-HD-Graphics-Driver... Version: 15.22.54.64.2622 (Latest) Date: 1/21/2012
(2) Intel® HD Graphics Driver for Windows* 7/8-64-bit https://downloadcenter.intel.com/download/24971/Intel-HD-Graphics-Driver... Version: 15.28.24.64.4229 (Latest) Date: 6/5/2015
The results are the same, either mediasdk_system_analyzer_64 or mediasdk_system_analyzer_32.exe just reports:
Version Target Supported Dec Enc

1.8 HW No

" - HW target does not work: If you expect it should, then make sure to install latest Intel gfx driver, and that Intel gfx is selected as primary driver"
Hence my conclusion is, given that Intel download center website doesn't provide Graphics Driver for Windows Server 2008 R2, it's unfortunate that similar drivers for Windows 7/Vista just don't fit in Windows Server 2008 R2 as expected. So I don't know where to get proper driver for this platform, and consequently make H.264 hardware encoder working on this.
Our requirement on Windows Server 2008 R2 is mandatory, could you please help on this ASAP?
thanks

Transcoding: H264 to HVEC / H265
I have a CCTV system, where there are 4 analog CCTV cameras connected to an Hikvision DVR box. Hikvision box has a C API which allows us to retrieve H264 streams from each of the 4 analog cameras. The problem we have is that the aggregate bandwidth is too much (~4 Mbps costs too much) since we plan to send this over the network. So what we are thinking is to transcode the stream with a more efficient codec like HVEC / H265.
This leads us to Intel Media SDK.
Is my understanding correct that I could just study the code in `sample_multi_transcode`? Will I be able to simply take the raw H264 stream and put it through the appropriate Intel Media SDK functions and it would be able to transcode the stream in real-time?
As for the hardware itself, I plan to use Skylake or Kerby Lake (when it's out) for maximum performance because, frankly, I'm afraid that the CPU performance will not be enough. The hardware running the program will be installed at each CCTV pole unsupervised and "low power" (as in, it cannot consume power like rack servers).

Feeding D3D surfaces to Quick Sync encoder MFT does not work
Media SDK Client or Media Server Studio version installed: unknown
Processor Type (required both for Linux & Windows OS): Intel(R) Core(TM) i7-5557U CPU
Driver Version(required only for windows OS): 20.19.15.4531
Operating System (required both for Linux & Windows OS): Windows 10 Pro 10.0.14393
Media SDK System Analyzer(only for windows OS): N/A
Concise Description of the Issue:
I want to encode video using the "Intel® Quick Sync Video H.264 Encoder MFT". I'm using the MFT manually, without using a paired decoder MFT, or any other MediaFoundation components. Feeding normal buffers (IMFSamples with buffers created by MFCreateAlignedMemoryBuffer) works well.
Now I'm investigating whether I can feed it ID3D11Texture2D surfaces as input (DXGI_FORMAT_NV12, 1280x720) in order to improve performance. I tried to pass IMFSample instances created with MFCreateVideoSampleFromSurface or MFCreateDXGISurfaceBuffer to IMFTransform::ProcessInput and made multiple experiments (trying different texture creation flags), but the best result was that all input samples were accepted, but no output samples produced. In case it matters, I never actually tried uploading data to the textures, assuming this would not make a difference from textures filled with garbage pixel data.
Additionally, I tried setting a IMFDXGIDeviceManager instance with IMFTransform::ProcessMessage and MFT_MESSAGE_SET_D3D_MANAGER, but this call returned E_FAIL. (The same works when doing hardware decoding with the Microsoft H264 decoder MFT.) In my understanding, this is a prerequisite for the hardware encoder to work.
Am I doing something wrong? Is this a bug in the Intel MFT? Is it just not supported?
I wish I could post a mftrace log, but the Intel MFT will fail with "Merit validation failed" under mftrace - there are others who seem to have this problem, but I've seen no solution.
There's another problem unrelated to the one described above. The Intel encoder MFT does not initialize the output IMFMediaType with MF_MT_MPEG_SEQUENCE_HEADER. This happens only after you send it a few input frames. Then the MFT will signal MF_E_TRANSFORM_STREAM_CHANGE, and add MF_MT_MPEG_SEQUENCE_HEADER.
This is very inconvenient. Usually you need MF_MT_MPEG_SEQUENCE_HEADER at the start of the transcoding process to e.g. write the CodecPrivate element for Matroska. The Microsoft encoder MFT does not show this unexpected behavior.
I'm working this around with a bad hack by encoding a dummy frame with CODECAPI_AVEncVideoForceKeyFrame and then discarding the first output sample (since trying to reset/flush the decoder MFT to forget previous input doesn't work either). I know that the underlying quick sync API can retrieve this information via MFX_EXTBUFF_CODING_OPTION_SPSPPS before sending any input frames, so this seems like an unnecessary complication.

which media sdk recommended for encoding
which media sdk recommended for encoding 8 SDI video HD sources simultaneously
with better performance quality CBR and low latency
using the following HW :
5th Generation Intel® Core™ i7 Quad Core @ 2.6GHz (Broadwell)
HD Graphics 5600
and with OS windows 7
Media SDK for client 2016 or Media server SDK or maybe the INDE framework
do you think maybe it is necessary to upgrade the core cpu to skylake or/and the HD Graphics or the OS ?

Kaby Lake: Real-time H264 to H265 Hardware Transcoding
I get 4 live CCTV camera feed aggregate at about 4 Mbps encoded in H264.
My objective is I would like to cut down on the bandwidth as I need to send this feed across the network. So I'm thinking this is where Intel Media SDK can help me. My hope is that the SDK could transcode – in real-time – H264 video stream to H265.
If I purchased the Kaby Lake processor, and wait a bit until the Intel Media SDK updated its software to fully support the new processor, will the SDK allow me to fully take advantage of transcoding in hardware (thus reducing CPU consumption, thus reducing heat and power requirements?)
Anyone could help give some details to get this geek excited? ;-)
Thanks!

h.264 decoder gives two frames latency while decoding a stream (Intel Media SDK)
Hi!
We are using Intel Media SDK while HW decoding h.264 video from stream and zero-latency is very important in this case.
We noticed that we get always latency of two frames.
After we send bitstream frame #N to decoder, we get decoded frame #(N-2).
We are using official samples (sample_decode) with d3d11 output, already set AsyncDepth = 1.
The other thing is that this 2-frames latency does not depend on HW decoding used or not in Intel Media SDK.
Note that this behaviour does not depend on system performance and if we provide 1fps at DecodeFrameAsync input, we receive first decoded frame with two seconds latency.
Can you please help us how to obtain real-time encoded frames with no latency.
Thank you very Much.

How to determine the computer hardware decoding capabilities?
I use Intel (R) _Media_SDK_2016.0.2 and directx9 to develop software
that installs on the client's computer to receive streams from the webcam for hardware decoding.
I currently only use the following code to determine whether to support hardware decoding.
bool IsSupportHWDecode()
{
mfxIMPL impl = MFX_IMPL_AUTO;
mfxSession session;
mfxVersion ver = { {1, 1 }};
memset(&session, 0, sizeof(session));
MFXInit(MFX_IMPL_HARDWARE_ANY | MFX_IMPL_VIA_ANY,&ver,&session);
MFXQueryIMPL(session, &impl);
MFXClose(session);
return MFX_IMPL_BASETYPE(impl) == MFX_IMPL_HARDWARE ? true:false;
}
Because the use of directx9 architecture, so whether the use of hardware decoding depends on whether the intel Graphics adapter is active.
(In Intel_Media_Developers_Guide.pdf, "the Intel Graphics adapter needed to have a monitor associated with the device to be active")
My question is how to know in advance to detect the hardware decoding can be used? Is there any other API can be used?
Including the detection of the above problems, hardware decoding limit ... and so on.
