Hello,

Is openGL supported with media sdk server ? Is there a demo/example ?

Regards,

Ran

Hi,

I am using screen capture module along with sample_encode module to capture my desktop image and encode it into h264 format. I am running this application on a Windows8 desktop machine and on a windows8 Microsoft surface device and it works fine.  Now I want to add the support of screen rotation feature for Microsoft Surface device.

At present when surface device is rotated at 90 degree then I get the captured output frame un-oriented but image is rotated inside. E.g. if original desktop resolution is 1920x1080 and it is rotated by 90 degree, then capture module delivers raw output frame of 1920x1080 resolution in which desktop image is rotated inside.

My objective in this case is to get a final output frame with 1080x1920 resolution (height width swapped )so that desktop image still looks un-rotated even though device is rotated.

I checked in media sdk and found that there is a rotation plugin which supports only 180 degree rotation and that too for jpeg decoding only. So is there any module/lib in media sdk which supports image rotation (by 90, 180 & 270 degree) during screen capturing or h264 encoding, or h264 decoding?

My environment details are as following:

IMSDK version: 6.0.0.349
Sample decode version: 6.0.0.49
OS: Windows 8.1
Graphics Card: Intel(R) HD Graphics 4400 with driver version 10.18.14.4294

Thanks.

hi, 

I need your help。

I download INDE Media SDK for Windows 6.0.0.388 and intel_media_sdk_2016， in win8 they goes well，but win7 handle keep increasing。

my code like this:

while（true)

{

...

MFXInit(m_session, &version);

....

MFXVideoENCODE_Init(m_session, &m_mfxEncParams);

...

MFXVideoENCODE_Close(m_session);
MFXClose(m_session);

Sleep(50);

}

loop open and close，it's wrong in the function MFXVideoENCODE_Init, in win7 handles can't be recovery and once add eight.

and I think maybe it's no problem in previou version, but I can't find the link to download. can you tell me.

Hi,

I am trying to understand the differences between what is exposed through the OpenCL VME extension on Intel hardware, and what is available through the HEVC GACC library that is available as part of the Intel Server Studio Media SDK. Is it right to assume that the HEVC GACC library is a wrapper around the OpenCL VME extensions and so one can do what the HEVC GACC library does by using the OpenCL VME extension, or does it use an orthogonal path to access the hardware altogether? Also, I notice that the OpenCL VME tutorial talks about using built-in kernels available as part of OpenCL 1.2. Can I use them also when using OpenCL 2.0 so that I can take advantage of SVM, or is that not an option with the VME? Also, which one is expected to be faster?

I am trying to understand which option would provide me faster and accurate motion estimates for HEVC encoding...

Appreciate any information that I can receive about this!

Pradeep.

hello Intel-giant,

   I have a question in mediasdk-tutorials-0.0.3. I found something below in simple_1_session/src/simple_session.cpp

    // If more recent API features are needed, change the version accordingly
    mfxIMPL impl = options.values.impl;
    mfxVersion ver = { {0, 1} };

   Q1. Is there any document or release note to describe the modifications among these mfxVersions ?? 

hello Intel friends,

OS: Ubuntu 12.04

       MediaSamples_Linux_6.0.16043175.175

       MediaServerStudioEssentials2015R6

Platform:  i5-4570S

      I use two bit-stream to be decoded correctly Just like the following and got failure as using combined bit-stream. Basically, the parameters are validated in each bit-stream and it should be OK. Why it fail to decode combined bit-stream??

[_build] $ pwd
/home/dspuser/Downloads/mediasdk-tutorials-0.0.3/_build
[_build] $ sudo ./simple_decode_vmem -auto test_stream.264     ==> validate first bit-stream
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva info: va_openDriver() returns 0

Execution time: 0.07 s (1421.59 fps)
[_build] $ sudo ./simple_decode_vmem -auto 1080p_4M.h264     ==> validate second bit-stream
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'

libva info: Found init function __vaDriverInit_0_32
libva info: va_openDriver() returns 0

Execution time: 1.04 s (611.63 fps)

     And I combined these two bit-streams and validate with ffmpeg. But I got failure as using simple_decode_vmem

[_build] $ cp test_stream.264 combined.264              ==> create combined bit-stream  
[_build] $ cat 1080p_4M.h264 >> combined.264        ==> create combined bit-stream

Platform:  i5-4570S

Q1. I found some description as below in simple_decode_vpp_pp.cpp, may I know the reason on "width must be a multiple of 16" and "height must be a multiple of 16 in case of frame picture and a multiple of 32 in case of field picture" ??

    // width must be a multiple of 16
    // height must be a multiple of 16 in case of frame picture and a multiple of 32 in case of field picture
    VPPParams.vpp.In.Width = MSDK_ALIGN16(VPPParams.vpp.In.CropW);
    VPPParams.vpp.In.Height =
        (MFX_PICSTRUCT_PROGRESSIVE == VPPParams.vpp.In.PicStruct) ?
        MSDK_ALIGN16(VPPParams.vpp.In.CropH) :
        MSDK_ALIGN32(VPPParams.vpp.In.CropH);

Q2. I didn't find any behavior about alignment in simple_decode_vmem.cpp but simple_decode.cpp and simple_decode_vpp_pp.cpp. Does it mean there's no alignment requirement in video memory? if not, why??

Thanks in advance 

Hi.

I had a problem by using the SDK.

So, I would like to encode single YUV frame into H.265 format. Basically I can do it with settings in the SDK sample sample_encode part.

But, when I try to mandate the frame type through mfxEncodeCtrl I get MFX_ERR_INVALID_VIDEO_PARAM error.

mfxEncodeCtrl control_buffer;
memset(&control_buffer, 0, sizeof(mfxEncodeCtrl));
control_buffer.FrameType = MFX_FRAMETYPE_IDR | MFX_FRAMETYPE_REF;

sts = m_pmfxENC->EncodeFrameAsync(&control_buffer, &m_pEncSurfaces[nEncSurfIdx], &pCurrentTask->mfxBS, &pCurrentTask->EncSyncP);

It looks like there is a conflict between encoder initialization and the control buffer. But this is for sure 1 frame to be encoded, so, I don't see any conflict points. Maybe someone knows why it produces an error ?

Hi.

I've downloaded evaluation of the Prof. Version of the MSS SDK. So, I'm able to use HEVC HW encoder but not decoder.

in /opt/intel/mediasdk/plugins/ there is no HW plugin. Only SW.

So, the question, how to get the HW decoder plugin ?

Here is output of the sample application: 

./sample_decode_drm h265 -i ~/Downloads/140803_4k_hm130_4s_sao_dbf_qp27.265 -o test.yuv -p 33a61c0b4c27454ca8d85dde757c6f8e

Hi.

I'm new to this SDK, so I would like to ask obvious question about HEVC FEI API.

I don't understand by the SDK documentation a way of using the mfxFEIH265Output structur in the MFXVideoENCODE_EncodeFrameAsync.

Maybe someone can point to me to the correct direction of usage ?

hello Intel-friends,

Platform:  i5-4570S

     As I trace the code of Simple_encode.cpp, I found something below and have question about reason of restriction of 2048. Do you know why?? Hardware design or else?? I have checked https://software.intel.com/sites/default/files/mediasdk-man.pdf but found no answer.

    w /= 2;
    h /= 2;
    ptr = pData->UV + pInfo->CropX + (pInfo->CropY / 2) * pitch;
    if (w > 2048)                                                                      ==> what the restriction means ??
        return MFX_ERR_UNSUPPORTED;

    I have three questions as below

Q1. the description "Video memory surfaces allow greater efficiency by avoiding explicit copies." in section 3.2 simple 2 decode vmem. What the "explicit copies" means ??

Q2. the description "By moving from system to video memory implicit copies are eliminated" in section 4.2 simple 3 encode vmem. What the "implicit copies" means ??.

Q3. As we know, the system memory has its frequency 1333Mhz (http://ark.intel.com/products/75044/Intel-Core-i5-4570S-Processor-6M-Cac...). But I can't find the video memory frequency in listed URL. Do you know where can I got the info??

There is a new Video Pro Analyzer(VPA) - 2016 R2 release, which make video analysis much easier. 
You can find more details about the release in What's new in Intel Video Pro Analyzer 2016 R2 article and the latest set of release notes, available here.  

Hi,

I am learning Media Server SDK and encode sample encodes fine when i use:

MFXVideoSession session;
sts = session.Init(MFX_IMPL_HARDWARE, &version);

Output:

hi Intel-giant,

Platform:  i5-4570S

I got questions as reading simple_encode_vmem_async.cpp

Q1. Is this parameter (AsyncDepth) platform-dependent ??  2 cores or 4 cores or else ?? Or did you mean it's better for all platform?? May I know how did you proof to result in good performance ??  

    // - AsyncDepth represents the number of tasks that can be submitted, before synchronizing is required
    // - The choice of AsyncDepth = 4 is quite arbitrary but has proven to result in good performance
    mfxEncParams.AsyncDepth = 4;

Q2. according to  the following, why the suggested frame number will be changed??

    // Query number of required surfaces for encoder
    mfxFrameAllocRequest EncRequest;
    ...
    sts = mfxENC.QueryIOSurf(&mfxEncParams, &EncRequest);
    ...

    EncRequest.NumFrameSuggested = EncRequest.NumFrameSuggested + mfxEncParams.AsyncDepth;   ==> why AsyncDepth was added ??

Thanks in advance...    QQa
