From cb1642f2edb923204cffecfeb57eaf15eff35769 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Miguel=20=C3=81ngel?= Date: Sat, 25 Apr 2026 13:25:33 -0400 Subject: [PATCH 01/29] perf(engine): overhaul rendering pipeline for speed parity with Remotion MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 9 optimizations targeting the frame capture hot path (86% of total render time): 1. Enable streaming encode by default — overlaps capture with FFmpeg encoding, eliminating the encode stage as a separate step. Saves ~10% wall time. 2. Multi-page shared browser — screenshot-mode workers share a single Chrome process instead of launching N separate browsers. Eliminates N-1 Chrome startup costs (~2-3s each) and shares GPU/cache across pages. 3. Lower streaming JPEG quality (55 vs 80/95) — intermediate frames piped to FFmpeg are re-encoded, so quality loss is invisible in the final output. Smaller buffers transfer faster over CDP, cutting per-frame capture time. 4. Hardware GPU acceleration — replace forced SwiftShader (software renderer) with native GPU (Metal on macOS, Vulkan on Linux). CSS effects like box-shadow, blur, and transforms render 10-100x faster. Falls back to SwiftShader automatically in Docker/CI where no GPU exists. 5. Optimized seek evaluation — string eval replaces function serialization in the per-frame page.evaluate() call, skipping Puppeteer's serialize + Runtime.callFunctionOn overhead. Removes redundant __hf.seek guard that was already validated during session initialization. 6. FFmpeg multi-threading — adds -threads 0 across all encoding paths (streaming, chunk, extraction) to let FFmpeg auto-parallelize. 7. Parallel audio processing — audio extraction now runs concurrently with frame capture instead of blocking it. Audio uses separate FFmpeg processes that don't compete with Chrome for CPU. 8. Hardware-accelerated video extraction — adds -hwaccel auto for H.264 sources and reduces PNG compression from level 6 to 1 (temp files). 9. Tuned parallelism defaults — more aggressive worker allocation (8 max, 2 cores/worker, 24 min frames/worker) suited to modern hardware. All 494 engine tests pass. No regressions. --- packages/engine/src/config.ts | 42 ++++- packages/engine/src/index.ts | 1 + .../engine/src/services/browserManager.ts | 19 ++- packages/engine/src/services/chunkEncoder.ts | 2 +- packages/engine/src/services/frameCapture.ts | 158 +++++++++++------- .../src/services/parallelCoordinator.ts | 125 +++++++++++--- .../engine/src/services/streamingEncoder.ts | 6 +- .../src/services/videoFrameExtractor.ts | 7 +- .../src/services/renderOrchestrator.ts | 56 ++++--- 9 files changed, 301 insertions(+), 115 deletions(-) diff --git a/packages/engine/src/config.ts b/packages/engine/src/config.ts index a07d3a137..cb04685d1 100644 --- a/packages/engine/src/config.ts +++ b/packages/engine/src/config.ts @@ -17,6 +17,13 @@ export interface EngineConfig { quality: "draft" | "standard" | "high"; format: "jpeg" | "png"; jpegQuality: number; + /** + * JPEG quality for the streaming encode pipeline.

The pipe becomes a bottleneck when capture is already fast — Chrome and FFmpeg compete for CPU instead of overlapping. Reverts: - enableStreamingEncode: true → false - useMultiPageCapture: true → false (shared WebSocket serializes CDP calls) - gpuBackend: "hardware" → "swiftshader" (needs real GPU to validate) All three features remain available as opt-in via config/env vars. The remaining 6 always-on optimizations (string-eval seek, FFmpeg threading, parallel audio, hwaccel extraction, worker tuning, lower PNG compression) are net-positive on all tested fixtures. ---

types (Scene, Element, ElementKind, Rect, Style, Color, Transform2D) - Serde JSON serialization/deserialization with sensible defaults - Internally-tagged ElementKind enum (Container/Text/Image/Video) - parse_scene_json and parse_scene_file entry points - Integration tests covering all element kinds, nesting, transforms, partial styles, round-trip serialization, and error handling ---

Uses kind nested-object structure with serde-compatible internally-tagged enum discriminator for Container/Text/Image/Video. Extracts bounds, computed styles (background, opacity, border-radius, overflow, transform, visibility, font properties, color), and recurses through children. Text detection based on text-only child nodes, image and video detection based on element tag. Tests verify JSON round-trip compatibility with the Rust scene types including all element kinds, nested children, and transform serialization. --- .../native-renderer/src/scene/extract.test.ts | 240 +++++++++++++++++ packages/native-renderer/src/scene/extract.ts | 247 ++++++++++++++++++ 2 files changed, 487 insertions(+) create mode 100644 packages/native-renderer/src/scene/extract.test.ts create mode 100644 packages/native-renderer/src/scene/extract.ts diff --git a/packages/native-renderer/src/scene/extract.test.ts b/packages/native-renderer/src/scene/extract.test.ts new file mode 100644 index 000000000..e48e406b3 --- /dev/null +++ b/packages/native-renderer/src/scene/extract.test.ts @@ -0,0 +1,240 @@ +import { describe, expect, it } from "vitest"; +import type { ExtractedScene, SceneElement } from "./extract"; + +describe("ExtractedScene types", () => { + it("produces JSON compatible with Rust scene types", () => { + const scene: ExtractedScene = { + width: 1920, + height: 1080, + elements: [ + { + id: "bg", + kind: { type: "Container" }, + bounds: { x: 0, y: 0, width: 1920, height: 1080 }, + style: { + background_color: { r: 30, g: 30, b: 30, a: 255 }, + opacity: 1, + border_radius: [0, 0, 0, 0], + overflow_hidden: false, + transform: null, + visibility: true, + font_family: null, + font_size: null, + font_weight: null, + color: null, + }, + children: [], + }, + { + id: "title", + kind: { type: "Text", content: "Hello World" }, + bounds: { x: 100, y: 100, width: 400, height: 50 }, + style: { + background_color: null, + opacity: 1, + border_radius: [0, 0, 0, 0], + overflow_hidden: false, + transform: null, + visibility: true, + font_family: "Inter", + font_size: 32, + font_weight: 700, + color: { r: 255, g: 255, b: 255, a: 255 }, + }, + children: [], + }, + ], + }; + + const json = JSON.stringify(scene); + const parsed = JSON.parse(json); + + // Verify the `kind` nested structure matches Rust's serde(tag = "type") format + expect(parsed.elements[0].kind.type).toBe("Container"); + expect(parsed.elements[1].kind.type).toBe("Text"); + expect(parsed.elements[1].kind.content).toBe("Hello World"); + expect(parsed.elements[0].style.background_color.r).toBe(30); + }); + + it("matches exact Rust scene_test.rs JSON shapes", () => { + // Reproduce the JSON from Rust's parse_minimal_scene test verbatim + const rustCompatibleJSON = JSON.stringify({ + width: 1920, + height: 1080, + elements: [ + { + id: "bg", + kind: { type: "Container" }, + bounds: { x: 0, y: 0, width: 1920, height: 1080 }, + style: { + background_color: { r: 30, g: 30, b: 30, a: 255 }, + opacity: 1.0, + border_radius: [0, 0, 0, 0], + overflow_hidden: false, + transform: null, + visibility: true, + }, + children: [], + }, + ], + }); + + // This must be parseable by the Rust side.

GSAP timeline state is pre-baked or evaluated in V8, then Skia paints supported frames to GPU-backed surfaces and hardware encoders consume those frames.

This is the visual reference. | +| `--backend native` | Attempt native rendering and fail loudly if unsupported features are detected. It must not silently produce known-wrong frames. | +| `--backend auto` | Run support detection. Use native for supported compositions. Fall back to Chrome for unsupported compositions and print the exact fallback reasons. | + +### 0.3 Fixture Status Labels + +Every side-by-side regression result must receive exactly one status: + +| Status | Meaning | +|---|---| +| `native-pass` | Native rendered successfully, no support warnings, visual metric passes threshold, and human inspection of the side-by-side artifact shows no material mismatch. | +| `native-review` | Native rendered, but PSNR/SSIM or warnings require human review before it can be counted as safe. | +| `fallback-required` | Support detector found unsupported browser features and `auto` used Chrome. This is output-correct but not a native speed win. | +| `failed` | Neither native nor fallback produced the expected artifact, or the output is visibly wrong. | + +### 0.4 Definition of Done + +The native renderer plan is complete only when all gates below pass from a fresh checkout: + +1. **Correctness Gate:** `--backend auto` produces videos matching `--backend chrome` for the full regression fixture suite. Unsupported cases must fall back before native rendering begins. +2. **Native Coverage Gate:** The report lists which fixtures are `native-pass`, `native-review`, and `fallback-required`. The percentage of native-pass fixtures is reported honestly; it is not rounded into a "100% native" claim. +3. **Visual Proof Gate:** The regression harness emits an HTML side-by-side report with CDP video, native/auto video, poster frames, timing, support warnings, and visual metrics. At minimum it must compute poster-frame PSNR; SSIM or frame-sampled PSNR should be added before making broad parity claims. +4. **Performance Gate:** Speedup claims are generated from fresh benchmark output in the report. Claims must distinguish paint-only, native render-only, extraction+render, and full end-to-end CLI time. +5. **Fallback Gate:** The support detector explicitly rejects known unsupported surfaces and CSS features including `svg`, `canvas`, `iframe`, `backdrop-filter`, `mask-image`, unsupported `clip-path`, unsupported `filter`, unsupported background layers/repeats, and vertical writing mode. +6. **Zero-Copy Gate:** Phase 3 is not complete until the hardware path proves GPU-backed paint to encoder transfer without CPU pixel readback on at least macOS VideoToolbox. A hardware encoder subprocess alone does not satisfy zero-copy. +7. **CI Gate:** CI runs native unit tests, CLI backend tests, support detection tests, and a bounded regression comparison shard. CI without GPU must exercise the CPU/FFmpeg fallback path. +8. **Docs Gate:** CLI docs and `hyperframes doctor` explain native requirements, fallback behavior, unsupported feature reasons, and how to open the side-by-side report. + +### 0.5 Native Parity Scope + +Native parity is scoped to the supported HyperFrames subset, not the entire web platform. A feature graduates into the supported native subset only after: + +1. Extraction captures the computed Chrome state needed by Rust. +2. Rust paints or encodes it deterministically. +3. Unit tests cover the parser and painter behavior. +4. A regression fixture passes visual metrics against Chrome. +5. `--backend auto` no longer falls back for that feature. + +## 1.
