#[repr(C)]
pub struct AVOptionRanges {
    pub range: *mut *mut AVOptionRange,

    pub nb_components: i32,
}
Expand description

List of AVOptionRange structs.

Fields

range: *mut *mut AVOptionRange
Expand description

Array of option ranges.

Most of option types use just one component. Following describes multi-component option types:

AV_OPT_TYPE_IMAGE_SIZE: component index 0: range of pixel count (width * height). component index 1: range of width. component index 2: range of height.

@note To obtain multi-component version of this structure, user must provide AV_OPT_MULTI_COMPONENT_RANGE to av_opt_query_ranges or av_opt_query_ranges_default function.

Multi-component range can be read as in following example:

@code int range_index, component_index; AVOptionRanges *ranges; AVOptionRange *range[3]; //may require more than 3 in the future. av_opt_query_ranges(&ranges, obj, key, AV_OPT_MULTI_COMPONENT_RANGE); for (range_index = 0; range_index < ranges->nb_ranges; range_index++) { for (component_index = 0; component_index < ranges->nb_components; component_index++) range[component_index] = ranges->range[ranges->nb_ranges * component_index + range_index]; //do something with range here. } av_opt_freep_ranges(&ranges); @endcode

nb_ranges: i32
Expand description

Number of ranges per component.

nb_components: i32
Expand description

Number of componentes.
