QuickSync failed to decode H264 using YV12 input

Hi.

the MFXVideoENCODE_Init function failed when FourCC set to  MFX_FOURCC_YV12;

Is that mean QuickSync doesn't support YV12 input or something I missed?

The source is:

m_mfxEncParams.mfx.FrameInfo.FourCC = MFX_FOURCC_NV12; //OK
//m_mfxEncParams.mfx.FrameInfo.FourCC = MFX_FOURCC_YV12; //NG
m_mfxEncParams.mfx.FrameInfo.ChromaFormat = MFX_CHROMAFORMAT_YUV420;
m_mfxEncParams.mfx.FrameInfo.PicStruct = MFX_PICSTRUCT_PROGRESSIVE;
status = MFXVideoENCODE_Init(session, &m_mfxEncParams);

The enviroment is;

Using the Intel® RealSense™ Camera with TouchDesigner*: Part 2

The Intel® RealSense™ camera is a vital tool for creating VR and AR projects. Part 2 of this article lays out how to use the Intel RealSense camera nodes in TouchDesigner to set up a render or real-time projections for multi screens, single screen, 180 degree (FullDome) and 360 degree VR renders. In addition the Intel RealSense™ camera information can be sent out to an Oculus Rift* through the TouchDesigner Oculus Rift TOP node. Includes sample .TOE files.

  • Timestamp issues in h264 decoding

    Hi,

    I am using Intel Media Server Studio 2015 – Graphics Driver, version 16.4.2.39163 and Intel Media Server Studio 2015 – SDK, version 6.0.16043166.166,  running on CentOS 7.0 with a Intel(R) Core(TM) i7-4770R.

    I am decoding a h264 stream, but the decoded output pts are sometimes decreasing, which messes up with my muxer. My program is based on the simple_decode tutorial, and I added the decode and presentation timestamps in the bitstream:

    Jpeg encoding

    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:

    HEVC SW decoder crash

    Hi

    I am using the HEVC software plugin to decode a live stream.

    The decoder randomly crashes (sometimes i got ~15000 decoded frames ~10 minutes and late I managed to get ~46200 decoded frames = ~30 minutes. the frame rate is 25 FPS). I just re-run my application without any changes...

    I don't do anything (right now) with the output, just wanted to test the stability of my code using the SW decoder.

    I use the same code to decode live AVC stream and so far it never crashed.

    callstack (if it helps...)

    older media sdk download

    I have a program that currently uses the Intel Media SDK for video encoding.  The sdk has not been updated in a while and the exact version of libmfxsw32.dll is: file version 4.12.12.3 and product version 4.0.0000.... so it's a fairly old version we are using.

    We are investigating two things. 1. Updating to new 32 bit binaries from the 2016 Media SDK that was recently released.  2.  Updating our application to 64 bit.  After doing either 1 or 2 the performance is noticeably worse.  Simply putting the older dll back fixes the problem but I do not have the older 64bit binaries.
