结构体 AVOptionArrayDef 

源代码
#[repr(C)]
pub struct AVOptionArrayDef { pub def: *const c_char, pub size_min: c_uint, pub size_max: c_uint, pub sep: c_char, }
展开描述

May be set as default_val for AV_OPT_TYPE_FLAG_ARRAY options.

Fields§

§def: *const c_char

Native access only.

Default value of the option, as would be serialized by av_opt_get() (i.e. using the value of sep as the separator).

§size_min: c_uint

Minimum number of elements in the array. When this field is non-zero, def must be non-NULL and contain at least this number of elements.

§size_max: c_uint

Maximum number of elements in the array, 0 when unlimited.

§sep: c_char

Separator between array elements in string representations of this option, used by av_opt_set() and av_opt_get(). It must be a printable ASCII character, excluding alphanumeric and the backslash. A comma is used when sep=0.

The separator and the backslash must be backslash-escaped in order to appear in string representations of the option value.
