Struct IMFByteStream

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

Available on crate feature mf only.

IIMFByteStream COM interface.

Automatically calls Release when the object goes out of scope.

Usually created with MFCreateMFByteStreamOnStream function.

Examples

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

let raw_data: Vec<u8>; // initialized somewhere

let stream = w::SHCreateMemStream(&raw_data)?;
let byte_stream = w::MFCreateMFByteStreamOnStream(&stream)?;
