## Notes

- `--help` explicitly mentions NVDec and QSV hardware decoding.
- Binary strings contain NVENC, NVDEC, QSV, AMD VCE/VCN, VAAPI, VideoToolbox and FDK-AAC related strings. These strings are evidence for review, not a complete legal or runtime capability determination.
- FDK-AAC strings were found; redistribution of this binary is marked as unresolved in `BUILDINFO.md`.
