- Method Detail
  - CVBufferRetain
```
public static CVBufferRef CVBufferRetain(CVBufferRef buffer)
```
    [@function] CVBufferRetain
    Retains a CVBuffer object
    Like CFRetain CVBufferRetain increments the retain count of a CVBuffer object. In contrast to the CF call it is NULL safe.
    
    Parameters:
    
    buffer - A CVBuffer object that you want to retain.
    
    Returns:
    
    A CVBuffer object that is the same as the passed in buffer.
  - CVBufferRelease
```
public static void CVBufferRelease(CVBufferRef buffer)
```
    [@function] CVBufferRelease
    Release a CVBuffer object
    Like CFRetain CVBufferRetain decrements the retain count of a CVBuffer object. If that count consequently becomes zero the memory allocated to the object is deallocated and the object is destroyed. In contrast to the CF call it is NULL safe.
    
    Parameters:
    
    buffer - A CVBuffer object that you want to release.
  - CVBufferSetAttachment

```
    [@function] CVOpenGLESTextureCacheCreateTextureFromImage
    Creates a CVOpenGLESTexture object from an existing CVImageBuffer
    Creates or returns a cached CVOpenGLESTexture texture object mapped to the CVImageBuffer and associated params. This creates a live binding between the CVImageBuffer and underlying CVOpenGLESTexture texture object. The EAGLContext associated with the cache may be modified, to create, delete, or bind textures. When used as a source texture or GL_COLOR_ATTACHMENT, the CVImageBuffer must be unlocked before rendering. The source or render buffer texture should not be re-used until the rendering has completed. This can be guaranteed by calling glFlush().
    Here are some example mappings:
    Mapping a BGRA buffer as a source texture: CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, GL_TEXTURE_2D, GL_RGBA, width, height, GL_RGBA, GL_UNSIGNED_BYTE, 0, &outTexture);
    Mapping a BGRA buffer as a renderbuffer: CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, GL_RENDERBUFFER, GL_RGBA8_OES, width, height, GL_RGBA, GL_UNSIGNED_BYTE, 0, &outTexture);
    Mapping the luma plane of a 420v buffer as a source texture: CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, GL_TEXTURE_2D, GL_LUMINANCE, width, height, GL_LUMINANCE, GL_UNSIGNED_BYTE, 0, &outTexture);
    Mapping the chroma plane of a 420v buffer as a source texture: CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, GL_TEXTURE_2D, GL_LUMINANCE_ALPHA, width/2, height/2, GL_LUMINANCE_ALPHA, GL_UNSIGNED_BYTE, 1, &outTexture);
    Mapping a yuvs buffer as a source texture (note: yuvs/f and 2vuy are unpacked and resampled -- not colorspace converted) CVOpenGLESTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, GL_TEXTURE_2D, GL_RGB_422_APPLE, width, height, GL_RGB_422_APPLE, GL_UNSIGNED_SHORT_8_8_APPLE, 1, &outTexture);
    
    Parameters:
    
    allocator - The CFAllocatorRef to use for allocating the CVOpenGLESTexture object. May be NULL.
    
    textureCache - The texture cache object that will manage the texture.
    
    sourceImage - The CVImageBuffer that you want to create a CVOpenGLESTexture from.
    
    textureAttributes - A CFDictionaryRef containing attributes to be used for creating the CVOpenGLESTexture objects. May be NULL.
    
    target - Specifies the target texture. GL_TEXTURE_2D and GL_RENDERBUFFER are the only targets currently supported.
    
    internalFormat - Specifies the number of color components in the texture. Examples are GL_RGBA, GL_LUMINANCE, GL_RGBA8_OES, GL_RG, and GL_RED (NOTE: On GLES3 use GL_R8 instead of GL_RED).
    
    width - Specifies the width of the texture image.
    
    height - Specifies the height of the texture image.
    
    format - Specifies the format of the pixel data. Examples are GL_RGBA and GL_LUMINANCE.
    
    type - Specifies the data type of the pixel data. Examples are GL_UNSIGNED_BYTE.
    
    planeIndex - Specifies the plane of the CVImageBuffer to map bind. Ignored for non-planar CVImageBuffers.
    
    textureOut - The newly created texture object will be placed here.
    
    Returns:
    
    Returns kCVReturnSuccess on success

    Creates or returns a cached CVMetalTexture texture object mapped to the CVImageBuffer and associated params. This creates a live binding between the CVImageBuffer and underlying CVMetalTexture texture object.
    Note that CoreVideo does not explicitly declare any pixel format types to be Metal compatible. The assumption is that if the CVPixelBufferMetalCompatibilityKey has been specified, all buffers will be Metal compatible (IOSurface backed), and thus it is the developer's responsibility to choose an appropriate Metal pixel format for the CVPixelBuffers.
    Here are some example mappings:
    Mapping a BGRA buffer: CVMetalTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, MTLPixelFormatBGRA8Unorm, width, height, 0, &outTexture);
    Mapping the luma plane of a 420v buffer: CVMetalTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, MTLPixelFormatR8Unorm, width, height, 0, &outTexture);
    Mapping the chroma plane of a 420v buffer as a source texture: CVMetalTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, MTLPixelFormatRG8Unorm width/2, height/2, 1, &outTexture);
    Mapping a yuvs buffer as a source texture (note: yuvs/f and 2vuy are unpacked and resampled -- not colorspace converted) CVMetalTextureCacheCreateTextureFromImage(kCFAllocatorDefault, textureCache, pixelBuffer, NULL, MTLPixelFormatGBGR422, width, height, 1, &outTexture);
    
    Parameters:
    
    allocator - The CFAllocatorRef to use for allocating the CVMetalTexture object. May be NULL.
    
    textureCache - The texture cache object that will manage the texture.
    
    sourceImage - The CVImageBuffer that you want to create a CVMetalTexture from.
    
    textureAttributes - A CFDictionaryRef containing attributes to be used for creating the CVMetalTexture objects. May be NULL.
    
    pixelFormat - Specifies the Metal pixel format.
    
    width - Specifies the width of the texture image.
    
    height - Specifies the height of the texture image.
    
    planeIndex - Specifies the plane of the CVImageBuffer to map bind. Ignored for non-planar CVImageBuffers.
    
    textureOut - The newly created texture object will be placed here.
    
    Returns:
    
    Returns kCVReturnSuccess on success

```
    [@function] CVPixelBufferCreateWithIOSurface
    Call to create a single CVPixelBuffer for a passed-in IOSurface.
    The CVPixelBuffer will retain the IOSurface. IMPORTANT NOTE: If you are using IOSurface to share CVPixelBuffers between processes and those CVPixelBuffers are allocated via a CVPixelBufferPool, it is important that the CVPixelBufferPool does not reuse CVPixelBuffers whose IOSurfaces are still in use in other processes. CoreVideo and IOSurface will take care of this for if you use IOSurfaceCreateMachPort and IOSurfaceLookupFromMachPort, but NOT if you pass IOSurfaceIDs.
    
    Parameters:
    
    surface - The IOSurface to wrap.
    
    pixelBufferAttributes - A dictionary with additional attributes for a a pixel buffer. This parameter is optional. See PixelBufferAttributes for more details.
    
    pixelBufferOut - The new pixel buffer will be returned here
    
    Returns:
    
    returns kCVReturnSuccess on success.
