AMF_VIDEO_ENCODER_OUTPUT_DATA_TYPE reports always frame type either 'NONE' or 'IDR'

[MichaelLudeo]

Hi. Immediately after querying the output I am trying to read the frame type with this code:

uint32_t picType = AMF_VIDEO_ENCODER_PICTURE_TYPE_NONE;
if (outputBuffer->GetProperty(AMF_VIDEO_ENCODER_OUTPUT_DATA_TYPE, &picType) != AMF_OK)
{
    assert(0);
}

I am always getting picType equal either 0 or 2. I tried different low latency and high quality modes but same happens. I am encoding in CBR mode and setting IDR period to be the same as the frame rate:

Result = m_AmfEncoder->SetProperty(AMF_VIDEO_ENCODER_IDR_PERIOD, IdrPeriod);

where idrPeriod = fps (30).

Also, I am forcing SPS/PPS onto the first frame,but it always reports frame type 'NONE' for the first frame. I expect the sequence in GOP to look smth like this: IDR,PPPPPPPPPPPPPP... IDR. Frame sizes vary, and the output video stream is playable, so it is clearly has to do with my settings or encoder reporting wrong info.

The output frame type is reported by this property:AMF_VIDEO_ENCODER_OUTPUT_DATA_TYPE_ENUM. 0 and 2 are IDR and P

Oh, And I am casting to AMF_VIDEO_ENCODER_PICTURE_TYPE_ENUM

Solved. Thanks.
