SetAcceleration returns MFX_ERR_UNSUPPORTED

[maxim-sharabayko]

Hello!

I want to test Intel Media SDK DirectShow filters, particulary H.264 Video Encoder. The problem I faced is that I cannot connect the H.264 Enc filter, even when I try to connect on Media SDK MPEG-2 Decoder, which, BTW, connects is properly connected.

So I debugged H.264 Decoder and found out that it fails to dispatch:
function call to SetAcceleration(MFX_IMPL_AUTO); in CBaseEncoder::CBaseEncoder() returns -3, which is MFX_ERR_UNSUPPORTED.

The version passed is Minor 1 Major 1 Version 65537. I tryed to pass Minor 0, Major 1, but didn't work.
Implementation is set to MFX_IMPL_AUTO. I also tryed MFX_IMPL_SOFTWARE, but didn't work!
MediaSDK is 2.0 Gold (downloaded today).

I checked that libmfxsw32.dll is in the same folder as the filter. hardware version (libmfxhw32.dll) I don't have for unknown reason.

Please help me to fix this problem as I don't have any more ideas on what to do!

Hi Nina,

Ok, the problem may be in DirectShow chain. We are just studying the major functionality of Media SDK, therefore there is no need for us to continue the problem investigation. I think it is easyer to debug the filters to find the problem.

Thanks for the reply on hardware mode.

Ok, I see and totally agree about debug :-) We can comeback to that issue later if needed.

You are always welcome!
