Well, in base_init(), it will create caps of sink_pad/src_pad from
codec_info, that is the former create_src_caps/create_sink_caps and
now gst_amc_codec_info_to_caps.

In set_format(), the passed in state(GstVideoCodecState, the
input_state) and calculated allowed_caps(negotiated with downstream)
are passed to create_amc_format, which will:
1. Get mime, profile/level from allowed_caps.
2. Get color-format, frame-rate, width and height from state.
3. Get other things like i-frame-interval from properties and calculation.

I think the code should be fine.
