>
> Key changes:
> - Integrated a worker thread and a pending queue to handle inference.
> - Prevents the main filter thread from blocking during model execution.
> - Aligns LibTorch backend behavior with the existing OpenVINO async
> implementation.
> - Improves overall throughput for deep learning filters using LibTorch.

> The implementation has been tested with various torch models to ensure
> stability and correct frame synchronization.

Thanks for the patch, is there PATCH 2/3 and 3/3?
