Jpeg encoding

Jump to solution

Hi.

I've encountered two problem in encoding jpeg with intel media sdk.

1. The MFXVideoENCODE_Init function always returns MFX_WRN_PARTIAL_ACCELERATION. Even using the sample_encode.exe,  the result is the same. Is that mean QuickSync does not support jpeg encoding? (using h264 is OK)

2. The time  between MFXVideoENCODE_EncodeFrameAsync and MFXVideoCORE_SyncOperation is 16ms. It seems much longer than I expected.

The parameter to init encoder is:

    mfxVideoParam m_mfxEncParams;
    memset(&m_mfxEncParams, 0, sizeof(mfxVideoParam));

    m_mfxEncParams.mfx.CodecId = MFX_CODEC_JPEG;
    m_mfxEncParams.mfx.EncodedOrder = 0; // binary flag, 0 signals encoder to take frames in display order
    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;

    // set frame size and crops
    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.FrameInfo.FrameRateExtD = 1;
    m_mfxEncParams.mfx.FrameInfo.FrameRateExtN = 0x1e;


    // JPEG encoder settings overlap with other encoders settings in mfxInfoMFX structure
    m_mfxEncParams.mfx.Interleaved = 1;
    m_mfxEncParams.mfx.Quality = 75;
    m_mfxEncParams.mfx.RestartInterval = 0;

    m_mfxEncParams.AsyncDepth = 4;

Hi There, 

Thanks for detailed description and log from the system analyzer tool. This helps us provide your complete system information. Currently you are using Intel(R) HD Graphics 4600, this is a 4th generation processor, on which JPEG  HW implementation for encoding is a Hybrid solution. It is not a full HW implementation. Hence when you run your application or sample_encode you can see  MFX_WRN_PARTIAL_ACCELERATION.

As, this is a Hybrid implementation(partial HW), slow performance is expected. Currently from 6th generation processor, includes full HW support for JPEG encode. To achieve better performance, I suggest upgrading your hardware to latest 6th generation processor. 

Thanks,
