#[repr(C)]
pub struct AVCodecDescriptor {
    pub id: AVCodecID,
    pub type_: AVMediaType,
    pub name: *const c_char,

This struct describes the properties of a single codec described by an AVCodecID. @see avcodec_descriptor_get()

Fields

id: AVCodecID

type_: AVMediaType

name: *const c_char

Name of the codec described by this descriptor. It is non-empty and unique for each codec descriptor. It should contain alphanumeric characters and ‘_’ only.

long_name: *const c_char

A more descriptive name for this codec. May be NULL.

props: c_int

Codec properties, a combination of AV_CODEC_PROP_* flags.

mime_types: *const *const c_char

MIME type(s) associated with the codec. May be NULL; if not, a NULL-terminated array of MIME types. The first item is always non-NULL and is the preferred MIME type.

profiles: *const AVProfile

If non-NULL, an array of profiles recognized for this codec. Terminated with AV_PROFILE_UNKNOWN.
