AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX means we can support AV_PIX_FMT_QSV by AVCodecContext.hw_device_ctx
This is not supported for qsv now. 
And even if it is supported, there is no business of system memory frame, just means output AV_PIX_FMT_QSV format frame created by hw_device_ctx.

Probably we need to add MFXVideoCORE_SetHandle() function for system memory output path, which is removed by 1f26a231bb065276cd80ce02957c759f3197edfa.
I will try to give a patch to fix it ASAP.
