JPEG Encode Hardware Acceleration

I have developed an application which encodes JPEG images around Media SDK 1.19.  On my development machine everything works well, however it is a Gen 5 Core CPU (i7-5820K) so the implementation fails back to Software.

On a second machine (Atom E3825) the application also works and automatically fails back to software implementation.

I went out and purchased a Gen 6 Skylake (Pentium E4400) CPU and motherboard so that I can test JPEG hardware acceleration.  Here is my problem:

When I run my application I get the response MFX_ERR_UNSUPPORTED from MFXVideoENCODE_Query.

If I change the IMPL from AUTO to SOFTWARE the program runs with no problems.

If I run the "sample_encode.exe" program provided by Intel like this: "sample_encode.exe jpeg -w 1920 -h 1080 -f 30 -q 90 -i test.bin -o test.jpg" it runs correctly but gives the warning "partial acceleration".

Here is my code for the video param:

                mfxVideoParam m_mfxEncParams;
		memset(&m_mfxEncParams, 0, sizeof(mfxVideoParam));
		m_mfxEncParams.mfx.CodecId = MFX_CODEC_JPEG;

		m_mfxEncParams.mfx.FrameInfo.FrameRateExtN = 120;
		m_mfxEncParams.mfx.FrameInfo.FrameRateExtD = 1;

		m_mfxEncParams.IOPattern = MFX_IOPATTERN_IN_SYSTEM_MEMORY;
		// frame info parameters
		m_mfxEncParams.mfx.FrameInfo.FourCC = MFX_FOURCC_YV12;
		m_mfxEncParams.mfx.FrameInfo.ChromaFormat = MFX_CHROMAFORMAT_YUV420;
		m_mfxEncParams.mfx.FrameInfo.PicStruct = MFX_PICSTRUCT_PROGRESSIVE;


		m_mfxEncParams.mfx.FrameInfo.Width = MSDK_ALIGN16(width);
		m_mfxEncParams.mfx.FrameInfo.Height = (MFX_PICSTRUCT_PROGRESSIVE == m_mfxEncParams.mfx.FrameInfo.PicStruct) ?
			MSDK_ALIGN16(height) : MSDK_ALIGN32(height);

		m_mfxEncParams.mfx.FrameInfo.CropX = 0;
		m_mfxEncParams.mfx.FrameInfo.CropY = 0;
		m_mfxEncParams.mfx.FrameInfo.CropW = width;
		m_mfxEncParams.mfx.FrameInfo.CropH = height;

		m_mfxEncParams.mfx.Interleaved = 1;
		m_mfxEncParams.mfx.Quality = 75;
		m_mfxEncParams.mfx.RestartInterval = 0;

		m_mfxEncParams.AsyncDepth = 1;

		m_mfxEncParams.mfx.BufferSizeInKB = width * height * 32 / 1024;

		mfxStatus status = MFXVideoENCODE_Query(*session, &m_mfxEncParams, &m_mfxEncParams);

And here are the results from mediasdk_system_analyzer_64.exe:

Additional Information:

Using Intel Media SDK 2016 R2

Using newest driver for Intel HD Graphics 510 - "15.20.48.4501(20.19.15.4501)".

When I make a request to MFXQueryIMPL the response is "514" which is not a valid IMPL value.

Hi Daniel,

Regarding JPEG HW encode is a new feature of Intel Media Sever Studio 2017 on Intel® 6th Generation Core™ Processors. It looks like your platform is not support JPEG HW encode yet.

 

Thanks,

Zachary

Hi,

I am seeing the same thing as Daniel - except that my cpu is an i7-6770HQ, which I believe from the docs should be supported HW JPEG encodes.  What can I do to diagnose the problem?

Cheers,

Steve

Thank you for the responses.  I was able to get it to work.  Steve, the key is that HW encode is only supported for 4:2:2 formats (in this case YUY2).  YV12 will always show partial acceleration.

I would like to get some clarification regarding JPEG Encode HW acceleration requirements.
I'm using The Intel® Media SDK 2016 R2 (API version 1.19) and indeed I'm getting the HW acceleration only on Intel® 6th Generation Core™ Processors or above.

But! in Release notes it is written that "Hardware acceleration is available through hardware implementations of the Media SDK Library coming with Intel® IrisTM and HD Graphics Driver for Microsoft* Windows* 7/8.1/10 on platforms with: 

  • 3 rd Generation Intel® CoreTM processors
  • 4 th Generation Intel® CoreTM processors 
  • 5 th Generation Intel® CoreTM processors 
  • 6 th Generation Intel® CoreTM processors 
  • 7 th Generation Intel® CoreTM processors"

So  what is right and what is wrong?
