Preserve RTP/RTMP session continuity across upstream stream_reset events by
forcing a keyframe on restart, remapping live timestamps, and keeping live
outputs open when the runtime requests reset continuity.
Disable idle auto-exit by default by changing ingest_idle_timeout_ms to 0,
removing validation that rejected 0, and only enforcing idle shutdown when a
positive timeout is configured in pipeline and ingest loops.
Also suppress libavformat FLV trailer header backfill attempts on RTMP sockets
and update the RTP output tester for the newer publisher create signature.
Docs are updated to state that 0 disables the idle timeout.
Move the legacy /camera/* contract into its own reference page so the main MCAP layout doc can stay focused on current bundled and copy-layout behavior.
Document the compatibility model explicitly: legacy single-camera is operationally equivalent to one-camera copy when the effective camera label is treated as the literal `camera`.
Update the mcap_rgbd_example helper and recipe docs to accept legacy /camera/* inputs under that compatibility rule instead of rejecting them.
Namespace single-source zed_svo_to_mcap outputs with a derived camera label so one-camera exports use the same copy-layout topic shape as current multi-camera copy files.
Use the per-camera frame and pose reference identifiers for those single-source outputs, document copy as the current one-camera wire shape, and clarify that legacy /camera/* files are retained only as a legacy contract.
Add a small mcap_rgbd_example helper plus mcap_recipes guide for summarizing bundled/copy MCAPs and exporting one RGB/depth sample, and update the validator and viewer wording/behavior to match the bundled-vs-copy semantics.
Add an opt-in multi-camera copy layout for zed_svo_to_mcap.
copy mode preserves each camera's original timestamps and cadence,
writes namespaced /zedN topics without /bundle, and supports
common-overlap or full-range export windows.
Update the batch wrapper, Python validator, RGBD viewer, and
documentation so copy-layout MCAP files are treated as a first-class
format rather than invalid bundled output.

Document the bundled and single-camera MCAP topic contract in docs/mcap_layout.md and link it from the README.
Add scripts/mcap_bundle_validator.py to summarize and validate both bundled /bundle-based MCAPs and single-camera /camera/* MCAPs from Python.
Validate bundled files against bundle-member presence counts and single-camera files against topic/schema expectations plus video/depth/calibration count rules.
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.
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.
Implement bundled multi-camera --start-frame semantics as synced-group\nindices from the common synced start, inclusive with --end-frame.\n\nUpdate zed_svo_to_mcap to skip synced groups before writing, keep\nsingle-camera raw SVO frame semantics unchanged, and adjust exact\nprogress totals for selected bundled windows.\n\nReplace the expensive bundled exact pre-count path with approximate\ntime-window progress when --end-frame is not set, and update the\nshared TTY progress bar helper to support fraction-based rendering.\n\nExpose --start-frame in the batch MCAP wrapper and document the\nbundled frame-window semantics and approximate progress behavior in\nthe README.
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.
Add a Python batch wrapper around zed_svo_to_mcap for multi-camera
segment exports. The new script supports dataset discovery, repeated
segment-dir inputs, CSV-driven ordering, skip/probe/report flows, dry-run,
and CUDA environment passthrough so kindergarten-style datasets can be
converted into one bundled MCAP per segment.
Extend zed_svo_to_mcap so bundled multi-camera mode accepts --end-frame
with synced-group semantics. In this mode the value is interpreted as the
last emitted synced frame-group index from the common synced start, while
--start-frame remains unsupported.
Vendor a minimal pose-config TOML and a sample segments CSV into this repo
so the MCAP workflow is self-contained. Update the README to document the
batch MCAP flow, use portable placeholders instead of machine-specific
absolute paths, and describe the expected dataset layout explicitly.
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.
Switch acceptance/fault/release scripts to project-local .sisyphus evidence roots and remove parent-repo path assumptions.
Also harden deterministic behavior with run-id-derived port allocation and tuned fault thresholds so release gate pass and injected-failure flows remain stable in standalone execution.
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.
