Can be used to refer to filters by name. Intended to be used when the filter chain is changed at runtime. A label can be assigned to a filter by prefixing it with '@name:', where 'name' is an user-chosen identifier. For example, a filter added with '-vf-add @label1:gradfun=123' can be removed with '-vf-del @label1'. If a filter with an already existing label is added, the existing filter is replaced with the new filter (this happens for both -vf-add and -vf-pre). If a filter is replaced, the new filter takes the position of the old filter, instead of being appended/prepended to the filter chain as usual. For -vf-toggle, labels are compared if at least one of the filters has a label; otherwise they are compared by filter name and arguments (like before). This means two filters are never considered equal if one has a label and the other one does not. |
