Member Function Documentation
Constructs a new convert query object. 
A convert query is used to ask for a conversion between one format and another. 
- Parameters:
- 
  
    | src_format | The source Gst::Format for the new query. |  | value | The value to convert. |  | dest_format | The target Gst::Format. |  
 
- Returns:
- The new Gst::QueryConvert. 
 
 
      
        
          | void Gst::QueryConvert::parse | ( | Format& | dest_format, | 
        
          |  |  | gint64 & | dest_value | 
        
          |  | ) |  | const | 
      
 
Parse the destination format and value of a convert query answer. 
- Parameters:
- 
  
    | dest_format | The storage for the Gst::Format of the destination value. |  | dest_value | The storage for the destination value. |  
 
 
 
      
        
          | void Gst::QueryConvert::parse | ( | Format& | src_format, |

          |  |  | Format& | dest_format, | 
        
          |  |  | gint64 & | dest_value | 
        
          |  | ) |  | const | 
      
 
Parse a convert query answer. 
Use the other parse() methods for parsing individual values.

          | Format Gst::QueryConvert::parse_dest_format | ( |  | ) | const | 
      
 
Parse the destination format of a convert query answer, returning the format. 
- Returns:
- The Gst::Format of the destination value. 
 
 
      
        
          | gint64 Gst::QueryConvert::parse_dest_value | ( |  | ) | const | 
      
 
Parse the destination value of a convert query answer, returning the value. 
- Returns:
- The destination value. 
 
 
      
        
          | Format Gst::QueryConvert::parse_src_format | ( |  | ) | const |
