[−][src]Function fermium::renderer::SDL_UpdateYUVTexture
pub unsafe extern "C" fn SDL_UpdateYUVTexture(
texture: *mut SDL_Texture,
rect: *const SDL_Rect,
Yplane: *const u8,
Ypitch: c_int,
Uplane: *const u8,
Upitch: c_int,
Vplane: *const u8,
Vpitch: c_int
) -> c_int
Update a rectangle within a planar YV12 or IYUV texture with new pixel data.
texture
The texture to updaterect
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.
Returns: 0 on success, or -1 if the texture is not valid.
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.
