Occasionally the Windows recorder produces MP4 files that are missing
the moov atom and contain duplicate/corrupted blocks inside mdat.
These files show a black screen or refuse to open.
This commit adds:
- tools/repair_corrupted_mp4.py
A standalone Python script that:
1. Parses MP4 atoms to locate the mdat payload.
2. Auto-detects duplicate/corrupted blocks via MD5 hashing.
3. Skips corrupted boundaries and finds the first clean IDR frame.
4. Injects a correct Baseline SPS/PPS for 2560x1440 (and fallback
presets for 1920x1080 / 3840x2160).
5. Converts AVCC NAL units to Annex-B and remuxes with ffmpeg.
- tools/REPAIR_GUIDE.md
Documentation covering root-cause analysis, quick-start usage,
manual segment override, and troubleshooting tips.
Validated on a 4.5 GB, ~60 min, 2560x1440@30fps recording that was
previously unplayable on both Windows and macOS.

Add MP4 repair tool for corrupted screen recordings
Add hyperdata_blender_sphere.ipynb that loads the blender_sphere GUI- automation dataset (screenshots, crops, action logs, trace captions), builds Zarr arrays, creates a local HyperData dataset, and pushes it to the HyperData Hub. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
… updates
- parser.py: add _build_meta_json() and Step 4 to run_pipeline() that
auto-generates meta.json with task, instruments, recording, pipeline,
and data statistics.
- hyperdata_blender_sphere.ipynb: load meta.json, push it via
ds.metadata.set('meta_json', ...), and verify roundtrip.

- ScreenshotExtractor: source per-action frames from inputs/frames/ (written by `ace record export`) instead of seeking a video, reusing all crop/scale/ marker logic from VideoScreenshotExtractor. - parser: auto-select extractor by inputs (mp4 -> video, frames/ -> screenshot). - process_actions: detect adjacent actions resolving to byte-identical full frames (frozen frames from sparse upstream capture) and warn, so degraded data quality is surfaced instead of silently producing mismatched crop/full. - trace_generator: configurable per-request timeout (API_TIMEOUT_MS) and surface vendor error messages on failed LLM HTTP calls.
