[FFmpeg-devel] [PATCH v2 0/3] avfilter/dnn: add async support for LibTorch backend

[Raja Rathour via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

This series implements asynchronous model execution for the LibTorch backend.
It introduces a dedicated worker thread and a task queue to prevent the main
filter thread from blocking during inference, aligning the Torch backend
functionality with the OpenVINO backend.

v2 changes:
- Split the implementation into 3 patches for better reviewability.
- Added proper thread joining and NULL pointer safety in dnn_free_model_th.
- Cleaned up comments to follow FFmpeg Doxygen standards.

Raja Rathour (3):
  avfilter/dnn_backend_torch: add async infrastructure
  avfilter/dnn_backend_torch: implement async execution logic
  avfilter/dnn_backend_torch: handle lifecycle of worker thread
