Hi,

Sample_vpp is not converting nv12 to yuy2 when using software acceleration. I tried sw dll (libmfxsw64.dll) from Intel(R) Media SDK 2018 R1 and Intel(R) Media SDK 2019 R1, and both produced same issue. You can reproduce it by simple command line:

sample_vpp -i test_1920x1080.nv12 -o out.yuv -sw 1920 -sh 1080 -scc nv12 -dw 1920 -dh 1080 -dcc yuy2 -lib sw

If I use hardware acceleration (-lib hw option) then this conversion is fine, so I think issue is in libmfxsw64.dll only.

Hi, 

is it possible to have a working commandline example of sample_hevc_fei_abr.

Thanks.

I'm trying to get access to hardware accelerated video compression on an Atom processor.  I did some preliminary work on an i7-4910MQ without issues, but I can't successfully call MFXVideoENCODE_Init on the E3950.  Is there some setting or other change I need?

When I compile the "simple_encode" tutorial project for x86, MFXVideoENCODE_Init will return MFX_ERR_MEMORY_ALLOC.  simple_encode.exe will print the following:

>simple_encode.exe -g 640x480 -b 74000 -f 30/1
 Could not allocate memory. c:\source\mediasdk-tutorials-0.0.3\simple_3_encode\src\simple_encode.cpp 167

When I compile the "simple_encode" tutorial project for x64, MFXVideoENCODE_Init causes an access violation and simple_encode.exe will exit without printing anything.

simple_session.exe works OK for both x86 and x64.

>simple_session.exe
Implementation: HARDWARE                 API Version: 1.27

I'm running Windows 10 Enterprise LTSC.  Compiling with Intel(R) Media SDK 2019 R1 on MS Visual Studio 2017.

Is hardware acceleration for Quick Sync supported in virtual machines now? Without passthrough. On Xeon. KVM or Hyper-V.

Thanks!

I have a Visual Studio 2017 C++ application using the Intel Media SDK 2016 to do H.264 encoding. I recently upgraded to the 2019 SDK in an attempt to get H.265 encoding working. Yesterday I reverted back to the 2016 SDK but my application is not working the same as before. It no longer detects Quick Sync Hardware encoding on the target machine. I have uninstalled the 2019 SDK, reinstalled the 2016 one, revert all code changes and rebuilt the project but that didn't work. I also had a friend build my source code against the 2016 SDK and the resulting .exe that he build worked as expected. When comparing the file he built to mine, the file sizes differ by a few KB suggesting they are somehow different.

How do you properly uninstall the 2019 SDK? Has anyone had experience with left-over files or registry values after an uninstall?

Do you provide examples with sample_fei and bitrate control?  Or else, can i encode interlace avc with single field mode without fei api?

For example, we need  encode like this:

./sample_fei -tff -single_field_processing -g 50 -encpak -i MediaSDK/tests/content/test_stream_176x96.yuv -o output.h264 -w 176 -h 96

with single_field_processing but also with bitrate control,

Hi ,

i have a project from collage regarding image processing, we decided to learn how to use intel's dedicated framework for that purpose.

i am struggling finding any basic guide to see examples regarding of how to use Intel® Media RAW Accelerator.

any help would be great ,thank you.

I have an application used to encode video using hardware acceleration and H.264. After upgrading my Intel Media SDK from 2016 to the 2019 one, the pEncoder->Init function returns MFX_ERR_MFX_ERR_INVALID_VIDEO_PARAM(-15).  Code below:

Can someone please tell me why m_VideoParam is invalid?

Well, in my situation, my encoding configuration is:

resolution=3840x2160

target bitrate=500kbps

fps=30

codec=h264

RC mode=CBR

And the real encoded bitrate is 4000kbps. And I found some sentences in this forum that said the limit of the compression ratio is 500x.

I can understand the real bitrate is mismatched now. But I want to make sure that the limit of the compression ratio is still 500x? Is h265 encoding the same?

BTW, there is a parameter named BitrateLimit in CodingOptionValue. I tried to set it to false, and nothing changed.

The monochrome 10bit images from openCV should be compressed in a H.265 file with Kaby Lake HW accelerator.

Because the supported formats are not b/w I changed to an RGB (CV_16UC3) image which is converted to YUV using cvtBGRtoTwoPlaneYUV.

	int fourcc = cv::VideoWriter::fourcc('H', '2', '6', '5');
	...
	params.mfx.CodecId = codecId;
	params.mfx.TargetUsage = MFX_TARGETUSAGE_BALANCED;
	params.mfx.TargetKbps = (mfxU16)cvRound(frameSize.area() * fps / 500); // TODO: set in options
	params.mfx.RateControlMethod = MFX_RATECONTROL_VBR;
	params.mfx.FrameInfo.FrameRateExtN = cvRound(fps * 1000);
	params.mfx.FrameInfo.FrameRateExtD = 1000;
	params.mfx.FrameInfo.BitDepthLuma = 10; // added by customer
	params.mfx.FrameInfo.BitDepthChroma = 10; // added by customer
	params.mfx.FrameInfo.FourCC = MFX_FOURCC_P010; // modified by customer
	params.mfx.FrameInfo.Shift = 1; // added by customer
	params.mfx.FrameInfo.ChromaFormat = MFX_CHROMAFORMAT_YUV420;
	params.mfx.FrameInfo.PicStruct = MFX_PICSTRUCT_PROGRESSIVE;
	params.mfx.FrameInfo.CropX = 0;
	params.mfx.FrameInfo.CropY = 0;
	params.mfx.FrameInfo.CropW = (mfxU16)frameSize.width;
	params.mfx.FrameInfo.CropH = (mfxU16)frameSize.height;
	params.mfx.FrameInfo.Width = (mfxU16)alignSize(frameSize.width, 32);
	params.mfx.FrameInfo.Height = (mfxU16)alignSize(frameSize.height, 32);
	params.IOPattern = MFX_IOPATTERN_IN_SYSTEM_MEMORY;

The changes from the openCV videoio code are highlighted. This results in the output:

FrameInfo: 
| FourCC: P010 (0x30313050)
| Size: 288x288
| ROI: (0;0) 288x288

| Shift: 1
| TemporalID: 0
| FrameRate: 10000/1000
| AspectRatio: 0x0
| PicStruct: 1
| ChromaFormat: 1

By calling write_one I get the output:

The ERR_MORE_DATA is normal according to the documentation. Because I did not find any documentation about the message MFX_ERR_UNDEFINED_BEHAVIOR I would like to ask the experts for support. Please let me know if I should take other formats to handle 10bit mono frames, etc. - Thank you, Christoph

hello, does Intel MediaSDK 2018R2 support decode 8k h264 (in hardware mode)? I did not find any information about this even in the release note

any response will be highly appreciated, thanks alot

Hello,

  I'm running encoder sample with "extbrc:on" and "d3d11" options, and MFXVideoENCODE_Init return MFX_ERR_UNKNOWN. But when i'm using system memory with extbrc, and it works fine.

  Could somebody tell me why and how to fix it?

Thanks!

I'm porting a windows transcoder to Linux, and running into an issue on the speed of decoding a 1080p H.264 video frame - the encoding works as expected.  Comparing the same feed from a low end Pentium Linux (N4200 - 1.1 GHz) to my Windows developer machine (i5-6500 - 3.2 GHz), the encode takes about 2x longer (as expected), but the decode takes 20x longer. (1+ milliseconds compared to over 26 milliseconds).  I'm wondering if there is something obvious I am doing wrong, or if this CPU isn't fully supported, or what ?

I'm running Ubuntu 19.10 server.

CPU: Intel(R) Pentium(R) CPU N4200 @ 1.10GHz

Installed the mfx packages: sudo apt-get -y install libmfx1 libmfx-tools libva-drm2 vainfo intel-media-va-driver-non-free
export LIBVA_DRIVER_NAME=iHD
Running: I see

libva info: VA-API version 1.5.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_5
libva info: va_openDriver() returns 0
awk: fatal: cannot open file `/etc/network/interfaces' for reading (No such file or directory)
 

As to my code: I'm opening up the VA display (_vaDisplay is shared between my encode/decode sessions)

    int _card = open("/dev/dri/card0", O_RDWR); /* primary card */
    VADisplay _vaDisplay = vaGetDisplayDRM(_card);
    VAStatus vaStatus = vaInitialize(_vaDisplay, &majorVersion, &minorVersion);
 

Opening up my session:

    mfxVersion min_version = { 3, 1 };  // min version 1.3 to support Low Latency.
    mfxStatus initStatus = MFXInit(MFX_IMPL_HARDWARE_ANY, &min_version, &session);
    initStatus = MFXVideoCORE_SetHandle(session, MFX_HANDLE_VA_DISPLAY, (mfxHDL)_vaDisplay);  // added for Linux

And the basic decode which I timed (obviously I do the DecodeHeader before, and necessary surface creation)

        sts = MFXVideoDECODE_DecodeFrameAsync(_session, &bitstream, inputFrame, &surface, &syncPoint);
        sts = MFXVideoCORE_SyncOperation(_session, syncPoint, MSDK_DEC_WAIT_INTERVAL);

Hi,

Hello,

I just gave a try to oneAPI VPL (2021.1-beta05)

During installation, it complained about unsupported OS. It required at least Win7* 64 Intel, which is precisely the one I run, so that was a first issue. Was it a bug of the installer, or a wrong system requirements description ?

Then I built a sample code to decode H264 with the vplWorkstream : it worked flawlessly (in TARGET_DEFAULT mode, TARGET_GPU won't run on my machine)

Finally, I built a sample code to encode H264 from raw YUV, and this time it failed. No error is raised by all the configuration, but EncodeFrame() returns 0 bytes and immediately sets the encoder's state to VPL_STATE_ERROR. Since it could be a misuse of my code, I switched to the sample code from https://github.com/intel/BaseKit-code-samples/tree/master/VideoProcessin..., and the behaviour is exactly the same : no visible error, until EncodeFrame() is called and returns 0 bytes with a VPL_STATE_ERROR state.

So I suspect that encoding is not supported on my system, but why, since decoding works ?

I also tried to use VPL_PROP_STATUS_CALLBACK, but no prototype is given in the header files, so I tried to guess it as

void myStatusCallback(vpl::Workstream* encoder, vplWorkstreamState status, void* data)

but it is never called anyway.

Is there a way to trace deep errors ?

According to https://docs.microsoft.com/en-us/windows/desktop/medfound/10-bit-and-16-... P010 stores values left shifted 6 bits, as if the values were originally 16 bits, but Intel Media SDK doesn't shift the values.  Bot HW and SW decoding in kaby lake behave the same.  https://software.intel.com/en-us/forums/intel-media-sdk/topic/731469 mentions that HW decoding used to be correct. Repro:

6
ffmpeg -i jelly.265 -pix_fmt yuv420p16le yuv420p16le.yuv
mfx.yuv should equal p010le.yuv but actually equals yuv420p10le.yuv (the Y plane is identical but mfx.yuv interleaves U/V like NV12 and yuv420p10le.yuv stores all Us before all Vs).  As expected the Y plane of yuv420p16le.yuv equals the Y plane of p010le.yuv, while the later interleaves U/V.
