Added input validations (`source_frame_count <= 0` or `target_frames_per_loop <= 0`) to `AutoLoopCalculatorLTX` (in `loop.py`), and `AutoLoopCalculator`, `AutoLoopCalculatorWan` (in `video.py`). When conditions are met, a safe default is returned to prevent math domain errors. Also included a new comprehensive unit test suite in `tests/test_loop_calculator.py`.
- Implemented unit tests for `extract_and_standardize_audio` in `video.py`.
- Added test case to verify exception handling when `torchaudio.load` fails.
- Expanded coverage to include resampling and channel standardization (mono/multichannel to stereo).
- Followed the repository's clean testing pattern for mocking dependencies and loading code under test.
Added `weights_only=True` to `torch.load()` in `video.py` to prevent insecure deserialization and potential arbitrary code execution via crafted pickle files. This change restricts the unpickler to only load tensors, primitive types, and basic containers, which is sufficient for the audio dictionary being loaded.
- Created tests/test_vram_node.py
- Mocked dependencies (torch, comfy) to allow testing in isolation
- Implemented test cases for zero values, exact GB, fractional values, small values (rounding check), and large values.
- Verified test robustness by confirming failure when logic was intentionally altered.
Replaces the shell-based subprocess call with list-based arguments and
separate invocations for 'apt-get update' and 'apt-get install'.
This eliminates the risk of command injection by avoiding shell
interpretation and properly handles the DEBIAN_FRONTEND environment
variable via sudo.
Updated `VideoAnalyzerWithAudio.analyze` to return `video_path` instead
of `video_name` in the result tuple. This bypasses the issue with
VHS_LoadVideo failing on complex filenames by directly passing the
absolute path to the video.
- Replaced VideoAnalyzerWithAudio class with improved UI handling logic.
- Implemented reference frame preview generation within the node.
- Added IS_CHANGED and VALIDATE_INPUTS class methods for correct caching and validation.
- Output formatting changed to return both UI payload and specific results tuple.
- Introduced global state memory (`global_source_frame_count`, `global_target_frames`, `global_stride`) in `loop.py`.
- Removed visual `source_frame_count` wire from `AutoLoopCalculator` in `video.py`
- Upgraded `AutoLoopCalculator` to execute as a blind "Explorer" in Cycle 0.
- Updated `LoadVideoWithSourceAudio` to intercept real `source_frame_count` directly from VHS payloads.
- Added dynamic calculation of total cycles based on intercepted frames at the end of Cycle 0.
