THE STACK, WITHOUT THE MARKETING LAYER

Architecture summaries use verified Real Labs technologies and production behavior. Public code artifacts are included only where actual source or terminal evidence is available and safe to expose.

SYS-01PRODUCTION

RealVideoCreator

Django · Python · PostgreSQL · FFmpeg · Celery · Redis · WebSockets

Full-stack video creation and editing platform spanning creator workflows, subscription logic, backend APIs, asynchronous exports, media orchestration, production monitoring, and deployment operations.

Creator UI→Django/API→Queue→FFmpeg→Export

PIPELINE BREAKDOWN

Interactive request/response work is separated from long-running media operations. Creator and project state stay in the application layer; export work is queued; progress reporting is decoupled from the media worker path.

Persistent creator/project state in Django/PostgreSQL.
Asynchronous media/export work through Celery/Redis.
FFmpeg-based processing and export orchestration.
Progress/status reporting separated from the export worker path.
Structured production logging for root-cause diagnosis.

PERFORMANCE CASE: 72ms → 4.82ms

A measured encoding path was instrumented and profiled, then restructured around the actual hot path. The measured path dropped from roughly 72ms to 4.82ms, a reduction of about 93%.

BEFORE 72ms AFTER 4.82ms

ENCODE PATH

Request state is separated from export execution. Media work is planned, queued, executed, measured, and reported without blocking the interactive creator path.

QUEUE CONTROL

Celery and Redis isolate long-running jobs from HTTP requests so worker pressure and user interaction can be diagnosed independently.

BILLING / WEBHOOKS

Subscription and entitlement logic lives at the application boundary. External billing events are handled as state transitions rather than UI assumptions.

FAILURE PROPAGATION

Worker failures need a path back to the application. Structured logs, persisted job state, and progress reporting keep export errors visible.

HOT PATH NOTE HTTP → project state → queue → worker → FFmpeg → artifact → progress

FIELD EVIDENCEStudio UI Export path Incident history

DOSSIER A1

REALVIDEOCREATOR PIPELINE BREAKDOWN

Full-stack creator platform spanning asynchronous media exports, billing state, internal business communications, database-backed workflows, and production delivery.

FULL-STACK VIDEO SYSTEM

01 // REQUEST TO EXPORT

Interactive state stays separate from media execution.

Creator actions modify application state. Long-running export work moves to the worker path. That keeps media execution from blocking normal HTTP requests and gives each failure domain a separate place to debug.

CREATOR UI→DJANGO→POSTGRESQL→CELERY→FFMPEG→EXPORT

02 // ENCODING HOT PATH

72ms became 4.82ms after the expensive path was measured instead of guessed.

The optimization story is not “made it faster.” The path was instrumented, the expensive stage was isolated, and the execution flow was restructured around the actual bottleneck. The measured result was roughly a 93 percent reduction.

≈93.3% reduction in the measured path

03 // WORKER AND PROGRESS PATH

Queue state and user-visible progress are different problems.

Worker execution is isolated from presentation. Progress must be reported without coupling the browser to the lifetime of one request, so async job state and real-time progress reporting remain independent of the export process itself.

request accepted
project state persisted
export queued
worker acquired job
media pipeline started
progress emitted
artifact completed
final state persisted

04 // BILLING BOUNDARY

Entitlements are application state, not a button state.

Subscription, billing, and webhook events belong at the backend boundary. The UI can present entitlement state, but external billing events must be reconciled against persistent application state.

05 // STAFF MAIL BUSINESS SYSTEM

Internal communications became a full application subsystem.

Staff Mail combines Django, PostgreSQL, SMTP and IMAP integration with per-mailbox recipient memory, private contact lookup, To/Cc/Bcc autocomplete, usage and recency ranking, secure inline-image composition, and authenticated message rendering.

Clipboard images can move from compose to CID/MIME delivery with image type checks, magic-byte validation, count and size enforcement, secure retrieval, and plain-text fallback. The mail transport layer remained isolated while the application features were expanded above it.

COMPOSE→CONTACT MEMORY→CID / MIME→SMTP / IMAP→STAFF MAIL

contact-memory tests      4 PASS
inline-image tests        3 PASS
existing regression tests 10 PASS
django system check       PASS
migration consistency     PASS
total automated tests     17 PASS

WHY THIS MATTERS

This architecture proves a creator-facing product can keep user interaction, persistent state, billing logic, background media work, and export failures separated enough to operate and debug under real production pressure.

TIMING MODEL

LUNA’s timing work centers on a shared timing model instead of allowing capture, render, audio, and encode stages to drift independently. The documented timing work holds A/V drift below 1ms across the covered capture paths.

GPU / RESOURCE LIFECYCLE

Real-time GPU systems fail when ownership, reuse, synchronization, and teardown are ambiguous. Resource lifecycle is treated as part of correctness, not cleanup after correctness.

GPU COMPOSITOR

D3D11 resources are treated as owned runtime objects with explicit lifecycle, reuse, synchronization, and teardown behavior.

CLOCK AUTHORITY

Capture, audio, render, and encode timing are forced to agree with one timing model instead of accumulating independent drift.

SYNC TARGET

The documented runtime work holds A/V drift below 1ms across the covered LUNA capture paths.

ENCODER PATH

Measured hot-path work reduced one encoding path from about 72ms to 4.82ms by profiling first and restructuring only the expensive path.

01 // TIMING MODEL REBUILD

Independent clocks are how real-time pipelines slowly tear themselves apart.

Capture, audio, rendering, and encoding cannot each invent their own idea of “now.” LUNA’s timing work rebuilt the clock model so the pipeline reasons from a shared timing authority and corrects drift before it becomes visible or audible.

02 // SUB-MILLISECOND A/V SYNC

<1ms DOCUMENTED DRIFT ENVELOPE Threshold visualization only. No synthetic time-series samples.

03 // GPU COMPOSITOR

Resource lifetime is part of correctness.

D3D11 surfaces, textures, overlays, and compositor state cannot rely on accidental lifetime. Ownership, reuse, synchronization, and teardown are explicit because a real-time GPU path is unforgiving when resources survive too long, disappear too early, or are reused while still in flight.

CAPTURE SURFACE→GPU RESOURCE→LAYER BLEND→OUTPUT FRAME

04 // RUNTIME HEALTH

A real-time engine needs to know when it is unhealthy before the user does.

Runtime health belongs beside timing and resource state. The important signals are not just crashes. Drift, stalled capture, bad resource transitions, missed frames, and encoder pressure are all early indicators.

05 // NATIVE WEBCAM ENGINE

The webcam path now has measured camera-to-GPU timing instead of a blind decode boundary.

Webcam capture moved from the FFmpeg-only ingestion boundary to a native Windows Media Foundation path while preserving the already-healthy LUNA LocalMailbox and RLGE GPU transport. Media Foundation callback timestamps now expose acquisition timing before the frame reaches the GPU path.

The application handoff is keeping up with every received sample and the previous permanent GPU starvation condition is gone. The remaining measured limitation is upstream acquisition cadence. The current source averages approximately 21.63 FPS instead of the selected 30 FPS-class target, so that investigation remains open.

SYS-03CROSS-DEVICE MEDIA

Real Gamers

Rust · Direct3D 11 · WASAPI · Android MediaProjection · H.264 · FFmpeg

LUNA / Stream Output

STABILITY UNDER LIVE LOAD

The hard problem is not “can a frame be captured?” It is keeping capture, rendering, audio, and output pacing coherent while the system remains responsive during live production.

CAPTURE

Windows-native capture and Android MediaProjection feeds enter controlled media paths where capture cadence, decode cadence, and presentation timing remain explicit.

RENDER

D3D11 rendering, surface ownership, and frame lifetime are kept explicit so live production does not depend on accidental GPU state.

AUDIO

WASAPI audio capture and mixing must remain synchronized with video output even when capture and render timing fluctuate.

JITTER

Frame pacing and buffering are part of stability. A fast pipeline that presents erratically is still a broken streaming pipeline.

FRAME PACING

Capture frequency is not automatically presentation timing. Stable output requires controlled pacing and deliberate buffering behavior.

AUDIO MIXING

Audio has its own timing and buffering behavior. It must remain aligned with the video path while both are under live load.

LIVE STABILITY

A pipeline can be fast and still be unusable. Jitter, starvation, resource churn, and unstable pacing are production failures even when nothing crashes.

MOBILE HOT PATH

ANDROID SCREEN → MEDIAPROJECTION → HARDWARE H.264 → TRANSPORT → FFMPEG → BGRA → D3D11 → GPU MAILBOX → LUNA

ANDROID CAPTURE

Real gameplay is captured through MediaProjection and VirtualDisplay, then encoded on-device with the Qualcomm hardware H.264 encoder. The validated landscape path produces a 1280x590 H.264 stream at a 4 Mbps target.

TRANSPORT + RECOVERY

The mobile publisher uses bounded buffering, preserves SPS/PPS codec configuration, emits clean IDR startup sequences, reconnects when the receiver disappears, and resynchronizes after reconnects or queue pressure.

GPU INGEST

FFmpeg decodes the mobile H.264 stream into BGRA frames, which enter the existing Rust capture path, upload through D3D11, publish through the bounded GPU mailbox, and become a live source inside the LUNA compositor.

WHY THIS MATTERS

Stable live media now crosses device and process boundaries. Android capture, hardware encoding, transport recovery, decode, GPU upload, pacing, audio, and presentation all have to stay coherent before gameplay becomes a dependable live production source.

PRODUCT INTEGRATION

Inference output becomes a platform artifact that must move through application state, storage, and creator workflow logic safely.

WHY THIS MATTERS

Inference becomes useful engineering only when model execution is observable, device behavior is controlled, and the result survives integration into the product workflow.

FIX-002

Make route semantics explicit

Directory URI and exact file delivery are different Nginx problems. Rewrite first, then alias the exact published file.

/portfolio/ → /portfolio/index.html

FIX-003

One source of truth

A publishing system cannot safely have two independently writable “live” files. Canonicalize, then verify every boundary with hashes.

DB == snapshot == HTTPS

FIX-004

Fail closed when patch assumptions break

An installer should stop on an unknown source shape instead of “best effort” editing production code.

unknown → abort → inspect → repatch

FIX-005

Interrogate each boundary

Editor, request payload, DB, filesystem snapshot, Nginx response, and browser runtime are separate layers. Test each one.

UI → payload → DB → file → HTTP → runtime

FIX-006

Never hydrate over an authoritative snapshot

If the visual CMS owns published content, legacy client-side JSON must not silently replace that content after load.

published HTML > stale jobs.json

FIX-007

Synchronize presentation and behavior metadata

If animation logic reads data-count, editing only visible text is incomplete. Update both before serialization.

textContent === data-count

FIX-008

Persist first, notify second

Hiring leads belong in durable application storage. Email is a notification channel, not the primary database.

POST → validate → save → notify

HOW TO FIX IT // COMPLETE INDEX

THE REPAIR PATH FOR EVERY INCIDENT.

… FIX / NEXT-ACTION RECORDS

Fixed incidents show the documented repair. Open incidents show the required fix, next action, or re-verification step preserved by the source log. No open item is presented as completed.

STATE IS NOT THE SAME AS PRESENTATION. PRESENTATION IS NOT THE SAME AS RUNTIME. RUNTIME IS NOT THE SAME AS DELIVERY.

THE STACK, WITHOUT THE MARKETING LAYER

RealVideoCreator

Interactive state stays separate from media execution.

72ms became 4.82ms after the expensive path was measured instead of guessed.

Latency comparison. Exact values only.

Queue state and user-visible progress are different problems.

Entitlements are application state, not a button state.

Internal communications became a full application subsystem.

LUNA Engine

Independent clocks are how real-time pipelines slowly tear themselves apart.

The target is not “looks synchronized.” The target is measurable drift.

Documented synchronization threshold, not a fabricated sampled trace.

Resource lifetime is part of correctness.

A real-time engine needs to know when it is unhealthy before the user does.

The webcam path now has measured camera-to-GPU timing instead of a blind decode boundary.
