Can't use GPU decoding #31

Closed NicolasProy closed 2 years ago

NicolasProy commented 2 years ago

Hi! I made a program using oneVPL to decode AVC and HEVC streams. While using this program with CPU implementation by initialising the session as follow, it works fine.

ImplValue.Type = MFX_VARIANT_TYPE_U32; ImplValue.Data.U32 = MFX_IMPL_TYPE_SOFTWARE; cfg[0] = MFXCreateConfig(loader); mfxStatus sts = MFXSetConfigFilterProperty(cfg[0], (const mfxU8*)"mfxImplDescription.Impl", ImplValue);

But when I try to use GPU capabilities (ImplValue.Data.U32 = MFX_IMPL_TYPE_HARDWARE;), decoding doesn't work. My IGP is an Iris Plus Graphics 655 and should be handled by oneAPI, and my drivers are up to date.

I tried to use the libraries installed by the oneAPI installer and also tried to compile from source with no result.

I can't figure out what I missed and could use a little help. Thanks in advance, Nicolas.

Hi Nicolas, can you print the output of the vpl-inspect tool here? It will show the adapters detected by oneVPL.

Hi Nicolas, From the vpl-inspect output Library path: C:\WINDOWS\system32\libmfxhw64.dll. It seems like you have legacy mediasdk driver. So, please refer the sample legacy-decode in examples\coreAPI. At first, please check with the legacy-decode whether it's working or not with -hw option. And please take a look at the code. oneVPL supports 2 different version of mediasdk drivers, "libmfxhw", and "libmfx-gen". The samples in examples\coreAPI are to show how to implement for legacy gen.

And, please post the error message as well when you have failed. It'd be very helpful to figure out what happens.

And, if you still see the errors, then please post source code as well.
