We only schedule composition when we have layer transaction or async animation. In current implementation, we can pass several video frames in one transaction, but we still need a layer transaction to trigger the composition.

I think we could check all imageLayer nodes at CompositorBridgeParent. if there are still have another video frames, CompositorBridgeParent can just do the composition for that video frames.
