Add gst_vaapi_encoder_set_bitrate() interface to allow the user control the bitrate for encoding. Currently, changing this parameter is only valid before the first frame is encoded. Should the value be modified afterwards, then GST_VAAPI_ENCODER_STATUS_ERROR_OPERATION_FAILED is returned. https://bugzilla.gnome.org/show_bug.cgi?id=719529
