Expand description
Update a rectangle within a planar NV12 or NV21 texture with new pixels.
You can use SDL_UpdateTexture as long as your pixel data is a contiguous block of NV12/21 planes in the proper order, but this function is available if your pixel data is not contiguous.
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.UVplane
the raw pixel data for the UV plane.UVpitch
the number of bytes between rows of pixel data for the UV plane.- Returns: 0 on success, or -1 if the texture is not valid.
