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.

\param texture the texture to update \param rect a pointer to the rectangle of pixels to update, or NULL to update the entire texture. \param Yplane the raw pixel data for the Y plane. \param Ypitch the number of bytes between rows of pixel data for the Y plane. \param UVplane the raw pixel data for the UV plane. \param UVpitch the number of bytes between rows of pixel data for the UV plane. \return 0 on success, or -1 if the texture is not valid.

\since This function is available since SDL 2.0.16.
