Detailed Description

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().

Field Documentation

graph

AVFilterGraph* AVFilterGraphSegment::graph

The filtergraph this segment is associated with.

Set by avfilter_graph_segment_parse().

chains

AVFilterChain** AVFilterGraphSegment::chains

A list of filter chain contained in this segment.

Set in avfilter_graph_segment_parse().

scale_sws_opts

char* AVFilterGraphSegment::scale_sws_opts

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.
