Function SDL_UpdateYUVTexture 

pub unsafe extern "C" fn SDL_UpdateYUVTexture(
    texture: *mut SDL_Texture,
    rect: *const SDL_Rect,
    Yplane: *const Uint8,
    Ypitch: c_int,
    Uplane: *const Uint8,
    Upitch: c_int,
    Vplane: *const Uint8,
    Vpitch: c_int,
) -> bool

Update a rectangle within a planar YV12 or IYUV texture with new pixel data.

You can use SDL_UpdateTexture() as long as your pixel data is a contiguous block of Y and U/V planes in the proper order, but this function is available if your pixel data is not contiguous.

Parameters

• texture: the texture to update.
• rect: a pointer to the rectangle of pixels to update, or NULL to update the entire texture.
• Yplane: the raw pixel data for the Y plane.
• Ypitch: the number of bytes between rows of pixel data for the Y plane.
• Uplane: the raw pixel data for the U plane.
• Upitch: the number of bytes between rows of pixel data for the U plane.
• Vplane: the raw pixel data for the V plane.
• Vpitch: the number of bytes between rows of pixel data for the V plane.

Return value

Returns true on success or false on failure; call SDL_GetError() for more information.

Thread safety

This function should only be called on the main thread.

Availability

This function is available since SDL 3.2.0.
