Method Detail

position

public avutil.AVOptionRanges position(long position)

Overrides:

position in class Pointer

range

public avutil.AVOptionRange range(int i)

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:

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);
