MFXVideoCORE_SyncOperation returns MFX_ERR_UNDEFINED_BEHAVIOR

Naresh_B_ · ‎02-19-2016

Hi,

I am working on an application which will use hardware accelerator to encode input frames in x264 compressing.

My application working fine with all windows versions like 7,8,10. But my problem is, I recently upgraded to windows10 and I got some driver updates and my application stops working. I debugged my code and I found MFXVideoCORE_SyncOperation returning MFX_ERR_UNDEFINED_BEHAVIOR which was work fine priviously(without windows10 update).

I followed intel SDK API reference manual to handle all my operations with accelerator and my application loading intel sdk version1.13.

I am very confused whether the problem with my application or driver updates.

Please help me in this.

Hi Naresh,

I will be happy to help you resolve this issue. But, I will need following details to better understand you system environment and pipeline:

1) We have latest SDK API 1.17 support available. Please check and upgrade to latest graphics drivers form https://downloadcenter.intel.com/ and to latest MSDK API: https://software.intel.com/en-us/media-sdk

2) Share your system details and attach a log from system analyzer tool.

3) You mentioned ("intel SDK API reference manual to handle all my operations with accelerator and my application"), can you share reproducer of your application and you can use MediaSDK samples https://software.intel.com/sites/default/files/MediaSamples_Windows_6.0.0.68.msi? Specifically, sample_encode app which includes complete HW encoding pipeline. This will help us understand MSDK parameters your are setting and scenario in your application.

Thanks,

Hi Harsh,

Thanks for your quick response.

1). As you suggested, I updated my SDKAPI to 1.17(but i am building my application with old headers and libs and runtime its loading 1.17 version API). Still i am seeing same issue.

2). And below one is mediasdk_system_analyzer log

The following versions of Media SDK API are supported by platform/driver:

Version Target Supported Dec Enc
1.0 HW Yes X X
1.0 SW No

3). I downloaded sample_encode app binary and tried with that .exe encoding is happening properly(is there any C version of samples).

Now my doubt, is there any problem with my encoder configuration?

But same configuration works for me before without any issue.

Below is my encoder configuration.

videoParam.mfx.CodecId = MFX_CODEC_AVC;
videoParam.mfx.TargetUsage = MFX_TARGETUSAGE_BALANCED;
videoParam.mfx.TargetKbps = enc->bitrate / 1024; //(enc->bitrate/1000 * GST_ROUND_DOWN_16(GST_VIDEO_INFO_WIDTH (info) * GST_ROUND_DOWN_16(GST_VIDEO_INFO_HEIGHT (info) ) /(1920*1088)));
videoParam.mfx.MaxKbps = videoParam.mfx.TargetKbps;//(enc->bitrate*3)/(2*1000); //videoParam.mfx.TargetKbps *3/2;
videoParam.mfx.RateControlMethod = MFX_RATECONTROL_CBR;
videoParam.mfx.FrameInfo.FrameRateExtN = enc->framerate;// info->fps_n; /**< not taking updated framerate; as the bitrate is set assuming 30 fps */
videoParam.mfx.FrameInfo.FrameRateExtD = 1;// info->fps_d;
videoParam.mfx.FrameInfo.FourCC = MFX_FOURCC_NV12;
videoParam.mfx.FrameInfo.ChromaFormat = MFX_CHROMAFORMAT_YUV420;
videoParam.mfx.FrameInfo.PicStruct = MFX_PICSTRUCT_PROGRESSIVE;
videoParam.mfx.FrameInfo.CropX = 0;
videoParam.mfx.FrameInfo.CropY = 0;
videoParam.mfx.FrameInfo.CropW = (GST_VIDEO_INFO_WIDTH(info));
videoParam.mfx.FrameInfo.CropH = (GST_VIDEO_INFO_HEIGHT(info));
videoParam.mfx.FrameInfo.Width = (GST_VIDEO_INFO_WIDTH(info));
videoParam.mfx.FrameInfo.Height = (GST_VIDEO_INFO_HEIGHT(info));

videoParam.mfx.CodecProfile = MFX_PROFILE_AVC_CONSTRAINED_BASELINE;

enc->bufsize = (guint)(GST_VIDEO_INFO_SIZE(info) + 1027);

//enc->videoParam.IOPattern = MFX_IOPATTERN_IN_SYSTEM_MEMORY | MFX_IOPATTERN_OUT_SYSTEM_MEMORY ;
videoParam.IOPattern = MFX_IOPATTERN_IN_SYSTEM_MEMORY;
videoParam.mfx.IdrInterval = 0; /** == 0, all I-frames are IDR */
videoParam.mfx.NumRefFrame = 2; /** number of reference frames */
if (nKeyFrameInterval <= 0)
nKeyFrameInterval = enc->keyint;
videoParam.mfx.GopPicSize = nKeyFrameInterval;//enc->keyint; /**< number of pictures in one GOP; == 1, only I-frames */
videoParam.mfx.GopRefDist = 1; /**< == 1; no B-frames; its the distance between I/P key frames */
/** BufferSizeInKB represents the maximum possible size of any compressed frames */
//videoParam.mfx.BufferSizeInKB = (enc->bufsize / 1024) + 1;
//videoParam.mfx.BufferSizeInKB = (enc->bufsize / 1024) + 1;
//videoParam.mfx.BRCParamMultiplier = 1;
/** */
//videoParam.mfx.InitialDelayInKB = (((((enc->bitrate) / 8)) / (1024)) / 4);

status = MFXVideoENCODE_Query(enc->session, &videoParam, &enc->videoParam);

if (status != MFX_ERR_NONE)
{
LOGE("error in Query\n");
#if 1
/** reset the harmless and required fields of
* Query output videoParam */
enc->videoParam.mfx.IdrInterval = 1; /** ==1, all I-frames are IDR */
enc->videoParam.mfx.NumRefFrame = 2; /** number of reference frames */
enc->videoParam.mfx.GopPicSize = enc->keyint; /**< number of pictures in one GOP; == 1, only I-frames */
enc->videoParam.mfx.GopRefDist = 1; /**< == 1; no B-frames; its the distance between I/P key frames */
#endif
}

status = MFXVideoENCODE_Init(enc->session, &enc->videoParam);

Hi Naresh,

Thank you for sharing logs and requested details. I do not see any issue with your encoder configuration and also MFX_ERR_UNDEFINED_BEHAVIOR is not one of the expected return status from MFXVideoCORE_SyncOperation ( Refer MSDK Manual, Page No.44 https://software.intel.com/sites/default/files/managed/47/49/mediasdk-man.pdf). I am assuming return code is not specifically from sync function.

For Q(3) I downloaded sample_encode app binary and tried with that .exe encoding is happening properly(is there any C version of samples). Now my doubt, is there any problem with my encoder configuration? But same configuration works for me before without any issue. -> As, sample_encode app is working, so issue is at application layer and not a driver issue. Here is a link tutorials (https://software.intel.com/sites/default/files/mediasdk-tutorials-0.0.3.zip) which are simplified version of samples in C. Please take a look at simple_3_encode and specifically session handling in the tutorial. Please check and confirm in your application if you are handling sessions correctly. If yes, please share a reproducer using either tutorial or sample, so we could reproduce this issue and help triage further. You might also be interested in taking a look at this article : https://software.intel.com/en-us/articles/framework-for-developing-applications-using-media-sdk. ;

Hi Naresh,

Glad, you have resolved the issue. I will go ahead an close this thread. Please start a new thread on forum, if any further questions.

Thanks,
