Field Documentation

◆ name

const char* AVFilter::name

Must be non-NULL and unique among filters.

Referenced by avfilter_graph_parse(), avgblur_opencl_filter_frame(), config_output(), convolution_opencl_filter_frame(), convolution_opencl_init(), lavfi_read_header(), neighbor_opencl_init(), print_digraph(), program_opencl_init(), and stack_init().

◆ description

const char* AVFilter::description

A description of the filter.

May be NULL.

You should use the NULL_IF_CONFIG_SMALL() macro to define it.

Definition at line 210 of file avfilter.h.

◆ inputs

const AVFilterPad* AVFilter::inputs

List of static inputs.

NULL if there are no (static) inputs. Instances of filters with AVFILTER_FLAG_DYNAMIC_INPUTS set may have more inputs than present in this list.

Definition at line 219 of file avfilter.h.

◆ outputs

const AVFilterPad* AVFilter::outputs

List of static outputs.

NULL if there are no (static) outputs. Instances of filters with AVFILTER_FLAG_DYNAMIC_OUTPUTS set may have more outputs than present in this list.

Definition at line 228 of file avfilter.h.

◆ priv_class

const AVClass* AVFilter::priv_class

A class for the private data, used to declare filter private AVOptions.

This field is NULL for filters that do not declare any options.

If this field is non-NULL, the first member of the filter private data must be a pointer to AVClass, which will be set by libavfilter generic code to this class.

Definition at line 238 of file avfilter.h.

◆ flags

int AVFilter::flags

A combination of AVFILTER_FLAG_*.

Definition at line 243 of file avfilter.h.
