Hr = MFSetAttributeSize(inputMediaType, MF_MT_FRAME_SIZE, width, height) Hr = inputMediaType->SetUINT32(MF_MT_INTERLACE_MODE, MFVideoInterlace_Progressive) Hr = inputMediaType->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_NV12) //my frames are indeed in NV 12 Hr = inputMediaType->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Video) My inputMediaType when I use the MFT encoder (and it works) Hr = outputMediaType->SetUINT32(MF_MT_ALL_SAMPLES_INDEPENDENT, FALSE)

Hr = outputMediaType->SetUINT32(MF_MT_FIXED_SIZE_SAMPLES, FALSE) Hr = outputMediaType->SetUINT32(CODECAPI_AVEncCommonQuality, 100) Hr = outputMediaType->SetUINT32(CODECAPI_AVEncCommonRateControlMode, eAVEncCommonRateControlMode_UnconstrainedVBR) Hr = outputMediaType->SetUINT32(MF_MT_MAX_KEYFRAME_SPACING, 16) Hr = MFSetAttributeRatio(outputMediaType, MF_MT_PIXEL_ASPECT_RATIO, 1, 1) Hr = outputMediaType->SetUINT32(MF_MT_MPEG2_PROFILE, eAVEncH264VProfile_Main) Hr = MFSetAttributeRatio(outputMediaType, MF_MT_FRAME_RATE, frameRate.first, cond) //typically (30, 1) Hr = MFSetAttributeSize(outputMediaType, MF_MT_FRAME_SIZE, width, height) //width and height 16-aligned Hr = outputMediaType->SetUINT32(MF_MT_INTERLACE_MODE, MFVideoInterlace_Progressive) Hr = outputMediaType->SetUINT32(MF_MT_AVG_BITRATE, bitRate) //bitrate is computed by a formula depending on frame size and fps

Hr = outputMediaType->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_H264) Hr = outputMediaType->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Video) Thanks, but it is exactly what I have tried.
