use Intel GPU Decode,Error initializing an MFX session: -3 #283

I need use Intel GPU decode,chosse AV_HWDEVICE_TYPE_QSV,but initializing error .show API version error .I install intel media sdk,but still error.

Not a binding issue or bug, firstly you are using precompiled ffmpeg binaries from repo which might be assembled with some flags musing or other call need done before initializing HW context. It how to setup environment as it based on tom old version of MFX. Just out of curiosity - why do you need outdated HW support for DXVA aka MFX?

I don't have Intel CPU with integrated GPU at reach so can help you much here, but the rest of options seems to be working fine - it same code for all codecs it not binding defiantly - besides you are using ffmpeg native binaries from repo it simply might be build without this feature or environment problem.
