NativeBuffer

interface NativeBuffer

An unmanaged memory pointer to a native platform buffer.

This is a shared contract between libraries to interact with native buffers without natively typed bindings.

Consumers, like react-native-skia or react-native-wgpu can accept a NativeBuffer-shaped object that has a pointer and a release function to unwrap the native buffer from it, load it as a GPU Texture, and release it once it has been rendered.

Example

const frame = ...
const nativeBuffer = frame.getNativeBuffer()
// your processing...
nativeBuffer.release()
frame.dispose()

Properties

pointer

readonly pointer: UInt64

A uint64_t/uintptr_t to the native platform buffer, with a retain count of +1.

• On iOS; this points to a CVPixelBufferRef
• On Android; this points to a AHardwareBuffer*

Methods

release()

release(): void

Release this reference to the platform buffer again, effectively decrementing the retain count by -1.
