AVFilterLink

public struct AVFilterLink

A link between two filters. This contains pointers to the source and destination filters between which this link exists, and the indexes of the pads involved. In addition, this link also contains the parameters which have been negotiated and agreed upon between the filter, such as image dimensions, format, etc.


                    
                    
                    source
