.SH NAME
SDL_UpdateNVTexture \- Update a rectangle within a planar NV12 or NV21 texture with new pixels\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3/SDL.h\(dq
.PP
.BI "int SDL_UpdateNVTexture(SDL_Texture *texture,
.BI "                         const SDL_Rect *rect,
.BI "                         const Uint8 *Yplane, int Ypitch,

.SH DESCRIPTION
You can use 
.BR 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\[char46]

.SH FUNCTION PARAMETERS
.TP
.I texture
the texture to update
.TP
.I rect
a pointer to the rectangle of pixels to update, or NULL to update the entire texture\[char46]
.TP
.I Yplane
the raw pixel data for the Y plane\[char46]
.TP
.I Ypitch
the number of bytes between rows of pixel data for the Y plane\[char46]
.TP
.I UVplane
the raw pixel data for the UV plane\[char46]
.TP
.I UVpitch
the number of bytes between rows of pixel data for the UV plane\[char46]
.SH RETURN VALUE
Returns 0 on success or a negative error code on failure; call

.BR SDL_GetError
() for more information\[char46]

.SH AVAILABILITY
This function is available since SDL 3\[char46]0\[char46]0\[char46]
