SharedTextureImportedSubtle Object

• getVideoFrame Function<VideoFrame> - Create a VideoFrame that uses the imported shared texture in the current process. You can call VideoFrame.close() once you've finished using the object. The underlying resources will wait for GPU finish internally.
• release Function - Release the resources. If you transferred and get multiple SharedTextureImported objects, you have to release every one of them. The resource on the GPU process will be destroyed when the last one is released.
  • callback Function (optional) - Callback when the GPU command buffer finishes using this shared texture. It provides a precise event to safely release dependent resources. For example, if this object is created by finishTransferSharedTexture, you can use this callback to safely release the original one that called startTransferSharedTexture in other processes. You can also release the source shared texture that was used to importSharedTexture safely.
• startTransferSharedTexture Function<SharedTextureTransfer> - Create a SharedTextureTransfer that can be serialized and transferred to other processes.
• getFrameCreationSyncToken Function<SharedTextureSyncToken> - This method is for advanced users. If used, it is typically called after finishTransferSharedTexture, and should be passed to the object which was called startTransferSharedTexture to prevent the source object release the underlying resource before the target object actually acquire the reference at gpu process asyncly.
• setReleaseSyncToken Function - This method is for advanced users. If used, this object's underlying resource will not be released until the set sync token is fulfilled at gpu process. By using sync tokens, users are not required to use release callbacks for lifetime management.
  • syncToken SharedTextureSyncToken - The sync token to set.
