Struct IBaseFilter

pub struct IBaseFilter(/* private fields */);

Available on crate feature dshow only.

IBaseFilter COM interface.

Automatically calls IUnknown::Release when the object goes out of scope.

Examples

use winsafe::{self as w, prelude::*, co};

let vmr = w::CoCreateInstance::<w::IBaseFilter>(
    &co::CLSID::EnhancedVideoRenderer,
    None,
    co::CLSCTX::INPROC_SERVER,
)?;
