SharedTextureHandle Object

• ntHandle Buffer (optional) Windows - NT HANDLE holds the shared texture. Note that this NT HANDLE is local to current process. Output textures of rgba, bgra, rgbaf16 formats don't have a keyed mutex on the texture handle, but nv12 format texture handles do have a keyed mutex.
• ioSurface Buffer (optional) macOS - IOSurfaceRef holds the shared texture. Note that this IOSurface is local to current process (not global).
• nativePixmap Object (optional) Linux - Structure contains planes of shared texture.
  • planes Object[] Linux - Each plane's info of the shared texture.
    • stride number - The strides and offsets in bytes to be used when accessing the buffers via a memory mapping. One per plane per entry.
    • offset number - The strides and offsets in bytes to be used when accessing the buffers via a memory mapping. One per plane per entry.
    • size number - Size in bytes of the plane. This is necessary to map the buffers.
    • fd number - File descriptor for the underlying memory object (usually dmabuf).
  • modifier string Linux - The modifier is retrieved from GBM library and passed to EGL driver.
  • supportsZeroCopyWebGpuImport boolean Linux - Indicates whether supports zero copy import to WebGPU.
