结构体 AVFilterGraphSegment 

#[repr(C)]
pub struct AVFilterGraphSegment {
    pub graph: *mut AVFilterGraph,
    pub chains: *mut *mut AVFilterChain,
    pub nb_chains: usize,
    pub scale_sws_opts: *mut c_char,
}

A parsed representation of a filtergraph segment.

A filtergraph segment is conceptually a list of filterchains, with some supplementary information (e.g. format conversion flags).

Created by avfilter_graph_segment_parse(). Must be freed with avfilter_graph_segment_free().

Fields

graph: *mut AVFilterGraph

The filtergraph this segment is associated with. Set by avfilter_graph_segment_parse().

chains: *mut *mut AVFilterChain

A list of filter chain contained in this segment. Set in avfilter_graph_segment_parse().

nb_chains: usize

scale_sws_opts: *mut c_char

A string containing a colon-separated list of key=value options applied to all scale filters in this segment.

May be set by avfilter_graph_segment_parse(). The caller may free this string with av_free() and replace it with a different av_malloc()’ed string.
