![]() ![]() It should be the same for notebooks, but i am not entirely shure for all cases there. If you slap in a dedicated GPU into a desktop machine most BIOS not even gray out all options for the IGPU but mostly This is at least on desktop systems the case. Normaly when there is a dedicated graphics card in your system the IGPU gets disabled. Maybe you got a completely different problem here but it sounds so familiar i had to answer. IGPU but your main graphics adapter is a dedicated GPU from AMD or NVIDIA then the INTEL MFT wont work. ![]() So if you are on Win 7 and if you have an INTEL But from what i read here in this thread INTEL seems to register its encoder also in Windows 7. If your CPU has an IGPU but your main graphics adapter is a dedicated graphics card and if the IGPU registers a Hardware MFT but the dedicated graphics card does not then the enumerated MFT of the IGPU is not functional.Īs far as i knew AMD and INTEL are installing their MFT's with their driver beginning with Windows 8.0. It all depends on your combination of dedicated and integrated graphics hardware and on what operating system you are. The above described problem can also happen with an AMD INTEL combo of course. Since NVIDIA is not offering any MFTs below Windows 10 you only get the IGPU's MFTs enumerated, but they are not functional internally. You will get anĮ_FAIL or E_UNEXPECTED if you try to use them. I had to google and test out a lot but it is a confirmed issue when you have an NVIDIA card and you are on an OS below Windows 10. Normaly drivers of dedicated GPUs are registering MFTs and overwrite what the IGPU driver might had registeredįor a certain format. The IGPU's MFTs are getting enumerated because the driver package installed them, but the adapter is not the main graphics adapter. The thing is you can create a class instance withĬoCreateInstance of the integrated encoder or decoder but as soon as you call any function on the class or you try to set an attribute ( like the async unlock for example which is needed to unlock async/hardware MFTs ) you will However the method will enumerate the Hardware Encoders and Decoders of the integrated graphics adapter ( IGPU ). Since NVIDIA's MFTs are only registered under Windows 10 they are not getting enumerated using Normaly MFTs are installed and registered with the driver package of the graphics card. If you have an NVIDIA card and you are not on Windows 10 then the problem is as follows : While AMD and INTEL are registering their Encoder MFT with their driver package since Windows 8.0, NVIDIA just started here with Windows 10. The problem is NVIDIA has good marketing but. ![]() I recently encountered a similar MFT enumeration and unlocking problem when using a system that has integrated graphics ( AMD APU with R7 ) but the main graphics adapter was an NVIDIA card. Somehow my guts telling me that you guys have From what i read Adam and persskog you are using Windows 7 right ? Do you have an NVIDIA card running or are you on integrated graphics only ? Please the others also post your OS and graphics cards. ![]()
