## Purpose Shuffled and delta-window batches can alternate video payloads and frame ordinals, causing avoidable decoder opens, backward seeks, and duplicate decoding. ## Changes - Decode base and delta rows in one batch. - Deduplicate identical frame descriptors. - Group by physical video and decode each group in frame order. - Restore the requested row order and preserve decoder LRU semantics. This changes neither the public API nor the `.video` format. Persisted TorchCodec `custom_frame_mappings` remains a separate format-level follow-up because current descriptors do not carry that mapping. ## Tests - `python -m unittest pypaimon.tests.multimodal_video_test pypaimon.tests.multimodal_lerobot_test` - `flake8 --config=dev/cfg.ini` on changed files -- This is an automated message from the Apache Git Service.
