Required Methods

fn CanPlayType( &self, audioonly: BOOL, mimetype: &BSTR, ) -> Result<MF_MEDIA_ENGINE_CANPLAY>

fn BeginCreateObject( &self, bstrurl: &BSTR, pbytestream: Ref<'_, IMFByteStream>, type: MF_OBJECT_TYPE, ppiunknowncancelcookie: OutRef<'_, IUnknown>, pcallback: Ref<'_, IMFAsyncCallback>, punkstate: Ref<'_, IUnknown>, ) -> Result<()>

fn EndCreateObject(&self, presult: Ref<'_, IMFAsyncResult>) -> Result<IUnknown>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
