Version

Metal rendering was added in version 1.5.

Defines

kOfxImageEffectPropMetalRenderSupported

Indicates whether a host or plug-in can support Metal render.

• Valid Values -

  • “false” - the host or plug-in does not support Metal render

  • ”true” - the host or plug-in can support Metal render

kOfxImageEffectPropMetalEnabled

Indicates that a plug-in SHOULD use Metal render in the current action.

If a plug-in and host have both set kOfxImageEffectPropMetalRenderSupported=”true” then the host MAY set this property to indicate that it is passing images as Metal buffers.

• Valid Values

  • 0 indicates that the kOfxImagePropData of each image of each clip is a CPU memory pointer.

  • 1 indicates that the kOfxImagePropData of each image of each clip is a Metal id<MTLBuffer>.

kOfxImageEffectPropMetalCommandQueue

The command queue of Metal render.

This property contains a pointer to the command queue to be used for Metal rendering (id<MTLCommandQueue>). In order to use it, reinterpret_cast<id<MTLCommandQueue>>(pointer) is needed.

The plug-in SHOULD ensure that its render action enqueues any asynchronous Metal operations onto the supplied queue.

The plug-in SHOULD NOT wait for final asynchronous operations to complete before returning from the render action.
