[windows ]build with meson: can't find mfx dependency

[boxerab]

I am using the topic_linux_and_windows branch.

I run a Visual Studio command prompt, and I run

set PKG_CONFIG_PATH=%GSTREAMER_1_0_ROOT_X86_64%lib\pkgconfig

Then, using meson with command

meson gstreamer-media-SDK gstreamer-media-SDK-build --backend=vs2017

I get the following output:

Can you check if MSDK is indeed working on your Windows 10 system by running MSDK sample apps?

[boxerab]

Thanks. What is the best way of testing this ?

[boxerab]

This is running on a KVM VM, by the way. Host is 8th Gen i7

[boxerab]

Thanks, Is there a sample h264 file that is supported, that I can test on ?

[boxerab]

I get these errors when I try the sample decoder in software mode:

[ERROR], sts=MFX_ERR_MORE_DATA(-10), CDecodingPipeline::InitMfxParams, m_FileReader->ReadNextFrame failed at c:\users\aaron\documents\intel« media sdk 2018 r2 - media samples 8.4.27.378\sample_decode\src\pipeline_decode.cpp:666

[ishmael1985]

Can you run sample_decode in hardware mode and use a proper H264 elementary stream? In GStreamer you can generate an H264 elementary stream with the following pipeline:

gst-launch-1.0 filesrc location=/path/to/video.mp4 ! qtdemux ! h264parse ! 'video/x-h264, stream-format=byte-stream' ! filesink location=/path/to/video.h264

[boxerab]

Thanks. I am getting errors from that pipeline.

[boxerab]

(gst-launch-1.0:7036): GStreamer-CRITICAL **: gst_element_make_from_uri: assertion 'gst_uri_is_valid (uri)' failed
WARNING: erroneous pipeline: syntax error

[boxerab]

I had to remove the quotes around video/x-h264 ... and put it into software mode, and then decode ran without error.

[ishmael1985]

Show me the output.

[boxerab]

After running pipeline, I was able to run sample_decode:

C:\Users\aaron\Documents\Intel® Media SDK 2018 R2 - Media Samples 8.4.27.378\_bin\x64>sample_decode.exe h264 -sw -i c:\temp\video.h264 -o test.yuv

[ishmael1985]

Run it in hardware mode instead of software mode, i.e. -hw instead of -sw, and show me the output.

[boxerab]

This is a VM, btw.

Output is

[ERROR], sts=MFX_ERR_UNSUPPORTED(-3), CDecodingPipeline::Init, m_mfxSession.Init failed at src\pipeline_decode.cpp:309

[ERROR], sts=MFX_ERR_UNSUPPORTED(-3), wmain, Pipeline.Init failed at src\sample_decode.cpp:686

[boxerab]

So, hardware decode not supported.

[boxerab]

So, it looks like MSDK is installed correctly.

[boxerab]

But MFX dependency is not found.

[ishmael1985]

Yes, and the gst-mfx plugins behaved as expected for your case. MSDK doesn't support a virtualized environment.

[boxerab]

Wait, so gst-mfx doesn't support software decode ?

[boxerab]

And that is why MFX dep is not found ?

[boxerab]

Because MSDK did work in software mode on my VM

[ishmael1985]

No, only hardware decode. For SW decode better use gst-libav. For the MFX dependency not being found, that was meant for building the gst-mfx plugins using open source MSDK in Linux with pkgconfig. For Windows it is not supported so that message came up for you but MFX library was found nevertheless.

[boxerab]

Thanks. I will test on Skylake, bare metal system. It would be nice to be able to run plugin in software mode, for testing purposes :)

[boxerab]

Also, it would be helpful to disable this message of MFX not found on Windows.

[boxerab]

I have a Skylake system with AMD discrete video card. Will I be able to use the iGPU on the CPU for this system ?

[ishmael1985]

You should be able to but let me know what you get.

[boxerab]

Unfortunately, I get the same error on my bare metal skylake system, with AMD dGPU

[boxerab]

[ERROR], sts=MFX_ERR_UNSUPPORTED(-3), CDecodingPipeline::Init, m_mfxSession.Init failed at src\pipeline_decode.cpp:309

[ERROR], sts=MFX_ERR_UNSUPPORTED(-3), wmain, Pipeline.Init failed at src\sample_decode.cpp:686

[boxerab]

Perhaps the h264 profile is not supported by hardware.

[boxerab]

A sample h264 that is known to work with Skylake decoder would be very useful.

[boxerab]

I ran the mediasdk_analyzer on my system:

Tips:
 - HW target does not work: If you expect it should, then make sure to install
   latest Intel gfx driver, and that Intel gfx is selected as primary driver.
 - If Intel driver is associated with secondary adapter, make sure to
   initialize DirectX device used with Media SDK with corresponding adapter.

[ishmael1985]

Your issue is described exactly as is. You may need to fiddle with the BIOS to make Intel GPU primary.
