Intel media sdk H.264 decoder handle leak

[Kazuya_K_]

I think bug in MediaSDK.

OS : Windows7 (x64)
SDK:API version 1.11

1. Create instance and initialize.

2. Execute decode operation.

3. Close operation.(reference to the sample code)

When performing the above operation, handle count increases one.
If does not execute decode, handle count does not increase.(create instance -> initialize -> close)

I think the wait handle that was created in asynchronous decoding has not been released.
If this is a bug, I hope to be fixed in the next release.

(Sorry, I'm using the online translation services.)

Hi,

We have new MSDK API release version 1.13 . Please run sample application again from the new version and send me logs. Also send me logs from System analyzer to know about HW configuration, with information of which MSDK sample you are using.

Thanks, 

[Kazuya_K_]

thank you for reply.

I have updated the SDK to version 1.13.
And rebuild the code, but did not improve.

My application was created in reference to the "intel_media_sdk_tutorial_041813 (simple_2_decode d3d)".

Hi,

I see that you are creating your own application using a tutorial. I highly suggest to use the our Samples as reference as they are regularly updated and we can look into further if you see the similar issue with the samples. Also, update the graphic driver to the latest from: https://downloadcenter.intel.com/ ;

[Kazuya_K_]

Driver version is the latest way.(10.18.10.4061)

Change "Intel Media Samples 6.0.0.98947 \ sample_decode" as shown below

#if defined(_WIN32) || defined(_WIN64)
int _tmain(int argc, TCHAR *argv[])
#else
int main(int argc, char *argv[])
#endif
{
	CDecodingPipeline*   Pipeline; // pipeline for decoding, includes input file reader, decoder and output file writer
	
	for(int count=0; count < 1000; count++)
	{
		sInputParams        Params;   // input parameters from command line
		//CDecodingPipeline   Pipeline; // pipeline for decoding, includes input file reader, decoder and output file writer
		Pipeline = new CDecodingPipeline();
		
		mfxStatus sts = MFX_ERR_NONE; // return value check

		sts = ParseInputString(argv, (mfxU8)argc, &Params);
		MSDK_CHECK_PARSE_RESULT(sts, MFX_ERR_NONE, 1);

		if (Params.bIsMVC)
			Pipeline->SetMultiView();//Pipeline.SetMultiView();

		sts = Pipeline->Init(&Params);//sts = Pipeline.Init(&Params);
		MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, 1);

		// print stream info
		Pipeline->PrintInfo();//Pipeline.PrintInfo();

		msdk_printf(MSDK_STRING("Decoding started\n"));

		for (;;)
		{
			sts = Pipeline->RunDecoding();//sts = Pipeline.RunDecoding();

			if (MFX_ERR_INCOMPATIBLE_VIDEO_PARAM == sts || MFX_ERR_DEVICE_LOST == sts || MFX_ERR_DEVICE_FAILED == sts)
			{
				if (MFX_ERR_INCOMPATIBLE_VIDEO_PARAM == sts)
				{
					msdk_printf(MSDK_STRING("\nERROR: Incompatible video parameters detected. Recovering...\n"));
				}
				else
				{
					msdk_printf(MSDK_STRING("\nERROR: Hardware device was lost or returned unexpected error. Recovering...\n"));
					sts = Pipeline->ResetDevice();//sts = Pipeline.ResetDevice();
					MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, 1);
				}

				sts = Pipeline->ResetDecoder(&Params);//sts = Pipeline.ResetDecoder(&Params);
				MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, 1);
				continue;
			}
			else
			{
				MSDK_CHECK_RESULT(sts, MFX_ERR_NONE, 1);
				break;
			}
		}
		msdk_printf(MSDK_STRING("\nDecoding finished\n"));
		delete Pipeline;
		Pipeline = NULL;
	}

    return 0;
}

Other parts are not changed.

When you compile and run this code, also an increase in handle count is seen.
(Command line arguments: h264 -d3d -hw -i test.h264)

Hi,

The operation you are performing  in the For loop where  you are creating a pipeline in the beginning and deleting it in the end of every run. On next run, when pipeline is created, it is not completely Null. So basically the operation you are trying to run by just modifying  the sample to work will not work as it was never  designed to handle the pipeline loop in the way you are making calls. But, I will send this information to the team and update.

Hi,

I have also an handle leak with H264 decoder.

I use some tools to detect where the problem occurs.

I think the problem is in the function MFXVideoDECODE_DecodeFrameAsync. This function call CreateEvent but event isn't close.

I work with IPP for 10 years. When we discovered a bug in IPP sample, it's possible to fix it, but unfortunately we haven't source code with IMS.

How to resolve this issue?

Do I need a driver update?

Edit: The problem depends of hardware/driver version

System 1: HANDLE LEAK

CPU : Intel i7-3770K

Motherboard : Intel DZ77BH-55K

GPU : Intel HD 4000 version 10.18.10.4061

OS : Windows 7 64bits

Software : x86 or x64

System 2: NO HANDLE LEAK

CPU : Intel i5-4250U

NUC D54250WYK 

GPU : Intel HD 5000 version 10.18.14.4080

OS : WES 7 64bits

Software : x86

Hi Laurent,

Please create a new thread with the issue you are facing with logs from System analyzer and information about the sample you are seeing this issue. This will help us better track the issues separately and avoid confusion.

Thanks,
