Make ZED MCAP export skip corrupted frame runs until recovery and
treat unreadable tail frames as end-of-stream instead of hard
failing conversion.
Update bundled nearest-mode export to emit partial bundles during
corruption gaps, extend BundleManifest with explicit member status
and skipped-frame counts, and only write payload messages for
present cameras.
Tighten batch probing so bundled MCAP validation checks /bundle
coverage and per-camera message counts, and improve failure
excerpts to include stderr tail output.
Also add a local cppzmq CMake fallback, refresh the multi-record
tester for the new bundle schema, and document the mixed NVENC
limitations in the README.
Add a new mcap_video_bounds helper binary plus a zed_segment_time_index.py CLI that builds and queries an embedded DuckDB index for bundled ZED segment recordings.
The index stores segment folders, MCAP paths, video time bounds, durations, camera labels, and dataset metadata, and reuses the existing recursive multi-camera segment discovery logic so nested kindergarten layouts are indexed correctly.
Infer a dataset default timezone from folder names versus MCAP timestamps, and make point queries precision-aware so second-level folder timestamps like 2026-03-18T12-00-23 resolve to the matching segment instead of missing due to subsecond start offsets.
Verification:
- uv add 'duckdb>=1.0'
- cmake --build build --target mcap_video_bounds
- uv run python -m unittest tests.test_zed_segment_time_index
- uv run python scripts/zed_segment_time_index.py build /workspaces/data/kindergarten --jobs 8
- uv run python scripts/zed_segment_time_index.py query /workspaces/data/kindergarten --at 2026-03-18T12-00-23
Default ZED MCAP export to neural_plus depth across the CLI and Python wrappers, and add tail-frame handling plus better corrupted-frame diagnostics in zed_svo_to_mcap.
Add mixed hardware/software worker pools to the batch MCAP wrapper, replace tqdm with progress-table on TTYs, keep text event logging and heartbeats for non-TTY runs, and document the NVENC session-limit rationale for mixed mode in the README.
Also refresh Python dependencies for the batch tooling and move the OpenSSL lookup in CMake so the local workspace build remains compatible with the vendored cnats setup.
Extract the tqdm-like stderr progress bar into a shared helper and reuse it across zed_svo_to_mp4, zed_svo_grid_to_mp4, and zed_svo_to_mcap.
For zed_svo_to_mcap, single-source exports now report exact frame totals and bundled multi-camera exports report exact synced-group totals on TTY. When bundled mode runs without --end-frame, the tool performs a counting pass first so the progress total remains exact instead of estimated.
Also document the bundled MCAP progress behavior in the README and record the current third_party dependency state in third_party/README. That note now makes it explicit that CLI11 and proxy are the active submodules, while tomlplusplus and mcap are vendored source drops, and adds a TODO to revisit converting mcap into a submodule later.
Verified with the Debug build during implementation, including single-camera and bundled zed_svo_to_mcap runs that rendered clean progress output to a TTY.
Extend zed_svo_to_mcap to export multiple SVO inputs or a kindergarten segment directory into a single MCAP with per-camera namespaced topics.
Add a MultiMcapRecordSink so one writer can manage independent video, depth, calibration, pose, and body channels for multiple cameras while reusing the existing protobuf schemas and encoded access-unit flow.
Implement strict timestamp synchronization for bundled exports by computing the common time window, seeking each SVO to the shared start, dropping unsynced frames, and only emitting groups that fall within the configured tolerance.
Load per-camera positional tracking settings from a cv-mmap style TOML pose config, preserve single-camera behavior, and add graceful SIGINT or SIGTERM shutdown so interrupted exports flush encoders and finalize readable MCAP files.
Add mcap_multi_record_tester coverage and switch zed_svo_to_mcap defaults to H.265 plus QUALITY depth mode.
Register an MCAP recorder service on the streamer control subjects, reuse the shared recording request and status model, and expose the zed recording preview/conversion helper.
This also replaces the temporary cnats boolean with the explicit CVMMAP_CNATS_PROVIDER modes and documents the supported system and workspace build paths.
Point the build and dummy runtime producer at the canonical protocol module so runtime ownership matches the refactored directory structure.
- compile src/protocol/wire_codec.cpp
- update frame source to include and use protocol::wire_codec
- remove remaining sim/wire usage from runtime code

Replace hand-rolled argument parsing with CLI11-backed parse paths for streamer runtime config and simulator runtime options.
Simulator help text is now generated from CLI11 app definitions to keep parser/help output in sync, while preserving legacy validation messages and exit semantics used by automation.
Remove the monorepo-relative spdlog fallback so this project no longer depends on ../app/lib/spdlog. This makes configuration deterministic when cvmmap-streamer is checked out as an independent repository.
The build now fails fast unless spdlog is provided by the host toolchain, which matches standalone packaging expectations.
This commit introduces the full downstream runtime implementation needed to ingest, transform, and publish streams.
It preserves the original upstream request boundary by packaging the entire cvmmap-streamer module (build config, public API, protocol and IPC glue, and simulator/tester entrypoints) in one coherent core unit.
Keeping this group isolated enables reviewers to validate runtime behavior and correctness without mixing test evidence or process documentation changes.
