结构体 AVFilterPadParams 

源代码 
#[repr(C)]
pub struct AVFilterPadParams {
    pub label: *mut c_char,
}
展开描述

Parameters of a filter’s input or output pad.

Created as a child of AVFilterParams by avfilter_graph_segment_parse(). Freed in avfilter_graph_segment_free().

Fields§

§label: *mut c_char

An av_malloc()’ed string containing the pad label.

May be av_free()’d and set to NULL by the caller, in which case this pad will be treated as unlabeled for linking. May also be replaced by another av_malloc()’ed string.
