This code doesn't define the profile used by the internal encoder, but it used to "predict" which is going to be used and to get the caps restrictions. Before the profile was predicted by checking the donwstream caps, but sometimes they are not defined, setting an unknown profile. In order to enhances this situation, the encoder asks to internal encoder if it has one. If so, it is used. To ask the internal encoder's profile a new accessor function was added: gst_vaapi_encoder_get_profile()
