}

Parameters describing a filter to be created in a filtergraph.

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

Fields

filter: *mut AVFilterContext

The filter context.

Created by avfilter_graph_segment_create_filters() based on AVFilterParams.filter_name and instance_name.

Callers may also create the filter context manually, then they should av_free() filter_name and set it to NULL. Such AVFilterParams instances are then skipped by avfilter_graph_segment_create_filters().

filter_name: *mut c_char

Name of the AVFilter to be used.

An av_malloc()’ed string, set by avfilter_graph_segment_parse(). Will be passed to avfilter_get_by_name() by avfilter_graph_segment_create_filters().

Callers may av_free() this string and replace it with another one or NULL. If the caller creates the filter instance manually, this string MUST be set to NULL.

When both AVFilterParams.filter an AVFilterParams.filter_name are NULL, this AVFilterParams instance is skipped by avfilter_graph_segment_*() functions.

instance_name: *mut c_char

Name to be used for this filter instance.

An av_malloc()’ed string, may be set by avfilter_graph_segment_parse() or left NULL. The caller may av_free() this string and replace with another one or NULL.

Will be used by avfilter_graph_segment_create_filters() - passed as the third argument to avfilter_graph_alloc_filter(), then freed and set to NULL.

opts: *mut AVDictionary

Options to be apllied to the filter.

Filled by avfilter_graph_segment_parse(). Afterwards may be freely modified by the caller.

Will be applied to the filter by avfilter_graph_segment_apply_opts() with an equivalent of av_opt_set_dict2(filter, &opts, AV_OPT_SEARCH_CHILDREN), i.e. any unapplied options will be left in this dictionary.

Trait Implementations

impl Clone for AVFilterParams

fn clone(&self) -> AVFilterParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AVFilterParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AVFilterParams

fn default() -> Self

Returns the “default value” for a type.

impl Hash for AVFilterParams

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AVFilterParams

fn cmp(&self, other: &AVFilterParams) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AVFilterParams

fn eq(&self, other: &AVFilterParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for AVFilterParams

fn partial_cmp(&self, other: &AVFilterParams) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
