…ytorch#9370) Summary: PLEASE DO NOT REVERT THIS DIFF. It would be highly disruptive for TorchVision. If you identify this diff as the source of issues, please ping me (NicolasHug) and I'll urgently prioritize a fix. ---- Pull Request resolved: pytorch#9370 Move the video_reader backend (C++ decoder and Python API) from the open-source torchvision/ folder to the internal-only fb/ folder. This prepares for removal of the deprecated video decoders from open-source GitHub while maintaining backward compatibility for internal Meta users. The move preserves all existing BUCK target paths via aliases, so existing internal consumers continue to work without modification. Python imports from torchvision.io are redirected to the fb/ location with OSS fallback stubs. This is one of many steps towards the removal of the torchvision video decoders. More stuff will come.
