bobframes 0.1.0

RenderDoc capture pipeline: ingest, analyze, render.

BobFrames

RenderDoc capture pipeline: ingest, analyze, render. Point it at a folder of .rdc captures and it produces _data/ (Parquet tables) plus _reports/ (static HTML you can browse). Windows-only in v1.

Requirements

• Windows 10 or later (the replay stage drives qrenderdoc, which is Windows-only in v1).
• Python 3.10 - 3.13.
• RenderDoc 1.x, or Arm Performance Studio, providing renderdoccmd and qrenderdoc on disk.

Install

pipx install bobframes
bobframes check

bobframes check prints the resolved paths for renderdoccmd and qrenderdoc and exits non-zero if either is missing, so you can confirm the toolchain before a long ingest.

Quickstart

cd path\to\captures      # a folder of <Area>\<YYYY-MM-DD[_label]>\*.rdc
bobframes ingest .       # export, parse, replay, parquetize, derive, render
bobframes serve .        # open a local static preview of the reports

ingest writes Parquet under _data/ and HTML under _reports/. Re-run bobframes render . any time to rebuild the HTML from existing Parquet without re-replaying captures.

Commands

Command	Purpose
ingest [root] [--area X] [--label Y] [--capture N] [--force] [--pixel-grid 4] [--render-only]	Full pipeline: export, parse, replay, parquetize, derive, manifest, commit, catalog, render.
render [root] [--area X] [--label Y]	Rebuild HTML and catalog from existing Parquet.
ab [root] --baseline-label X --compare-label Y	All reports for one drop pair under _reports/ab/<pair>/.
report [root] <name>	Build one named report (draws-by-class, trend, instancing, pass-gpu, shader, overdraw, dashboard).
catalog [root]	Rebuild _data/_catalog.parquet only.
lint <file>...	Check HTML or markdown against the banlist.
check	Print resolved tool paths; non-zero when a tool is missing.
serve [root] [--port 8000] [--bind 127.0.0.1]	Static preview via the stdlib HTTP server.
smoke [--data DIR]	End-to-end check; render-only against the bundled fixture when --data is omitted.
version	Print bobframes, schema, and pyarrow versions.

<root> is positional and defaults to .. Flags are long-form only. Exit codes: 0 success, 1 pipeline or build failure, 2 usage error, 3 external tool missing, 4 interrupted.

External tools

The export stage runs renderdoccmd convert; the replay stage runs qrenderdoc --python. v1 looks for both at a baked Arm Performance Studio install path and on PATH. A config file and a tool-resolver with version globbing arrive in v0.2; until then, install RenderDoc where v1 expects it or put the executables on PATH. Run bobframes check to see what was resolved.

Output layout

<root>/
  index.html                          root catalog view
  <area>/<drop>/                      raw RDC inputs (left untouched)
  _data/                              pipeline outputs
    _catalog.parquet (+ .csv, .json)
    _global_entities.parquet (+ .csv)
    _query_examples.md
    <area>/<drop>/                    per-drop data (29 Parquet tables)
      *.parquet (+ matching .csv)
      _manifest.json, _resource_labels.json
      shader_src/*.glsl, jsonl sidecars
      done.marker
  _reports/                           rendered HTML
    *.html (dashboard + reports)
    ab/<pair>/*.html
    drill/<area>/<drop>/index.html    per-drop browser
    _cache/

The catalog stores each drop's path relative to <root> for portability.

Migrating from _analysis

v1 is a hard rename of the older project-embedded _analysis package, with no compatibility shim: python -m _analysis.* stops working once bobframes is installed. Map old invocations to new ones:

Old (_analysis)	New (bobframes)
python -m _analysis.run --root . --area X --label Y	bobframes ingest . --area X --label Y
python -m _analysis.reports.ab --root . --baseline-label X --compare-label Y	bobframes ab . --baseline-label X --compare-label Y
python -m _analysis.lint <file>	bobframes lint <file>
python -m _analysis.tests.smoke	bobframes smoke

Troubleshooting

Symptom	Resolution
renderdoccmd not found (exit 3)	Install RenderDoc or Arm Performance Studio, or put the executable on PATH; confirm with bobframes check.
qrenderdoc replay hangs	v1 kills the replay process tree on timeout and records capture_status='replay_failed' for that capture; the rest of the drop still completes. Re-run with --force to retry.
Lint failure during render	The emitted HTML contains a banned token. Run bobframes lint <file> to see the line and label.
schema mismatch (exit 1)	A drop's _manifest.json schema version differs from the installed schema. Rebuild it with bobframes ingest --force (the v1 schema-migration path; see G-3).
Permission denied on _data	Close any viewer holding a Parquet open, then re-run; writes are staged and renamed atomically.

Advanced

• A/B reports: bobframes ab . --baseline-label OLD --compare-label NEW builds a side-by-side set.
• Programmatic use: import bobframes.schemas, bobframes.discovery, and bobframes.paths to drive table lookups, drop discovery, and path resolution from your own scripts.
• bobframes/probes/whatif.py is a manual qrenderdoc-side probe and is not wired as a CLI command.
• A TOML config file, an externalized draw classifier, and design-token theming are planned for v0.2.
