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.

§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.
  • UVplane: the raw pixel data for the UV plane.
  • UVpitch: the number of bytes between rows of pixel data for the UV 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.
