rustdesk 9343affe0b fix: check the frame QueryInterface result in dxgi capture
Both AcquireNextFrame paths cast the IDXGIResource to ID3D11Texture2D
without looking at the HRESULT. ohgodwhat() then dereferences the null
pointer in GetDesc(), and get_texture() hands a null texture to the vram
encoder. Return the error instead.

scrap

Scrap records your screen! At least it does if you're on Windows, macOS, or Linux.

Usage

[dependencies]
scrap = "0.5"

Its API is as simple as it gets!

struct Display; /// A screen.
struct Frame; /// An array of the pixels that were on-screen.
struct Capturer; /// A recording instance.

impl Capturer {
    /// Begin recording.
    pub fn new(display: Display) -> io::Result<Capturer>;

    /// Try to get a frame.
    /// Returns WouldBlock if it's not ready yet.
    pub fn frame<'a>(&'a mut self) -> io::Result<Frame<'a>>;

    pub fn width(&self) -> usize;
    pub fn height(&self) -> usize;
}

impl Display {
    /// The primary screen.
    pub fn primary() -> io::Result<Display>;

    /// All the screens.
    pub fn all() -> io::Result<Vec<Display>>;

    pub fn width(&self) -> usize;
    pub fn height(&self) -> usize;
}

impl<'a> ops::Deref for Frame<'a> {
    /// A frame is just an array of bytes.
    type Target = [u8];
}

The Frame Format

  • The frame format is guaranteed to be packed BGRA.
  • The width and height are guaranteed to remain constant.
  • The stride might be greater than the width, and it may also vary between frames.
