结构体 AVDeviceInfo 

#[repr(C)]
pub struct AVDeviceInfo {
    pub device_name: *mut c_char,
    pub device_description: *mut c_char,
    pub media_types: *mut AVMediaType,
    pub nb_media_types: c_int,
}

Structure describes basic parameters of the device.

Fields

device_name: *mut c_char

< device name, format depends on device

device_description: *mut c_char

< human friendly name

media_types: *mut AVMediaType

< array indicating what media types(s), if any, a device can provide. If null, cannot provide any

nb_media_types: c_int

< length of media_types array, 0 if device cannot provide any media types
