🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
The legacy 8.1 samples header is never replaced.
Two defects prevent the SDK sample header replacement from running:
- Lines 166-168 return early when the staged
nv-codec-headerscheckout already containsnvEncodeAPI.h. On any repeat build, or when a user setsRECORDLY_NVENC_HEADERS_ROOTto an existing checkout, the replacement code at Lines 182-194 never executes. - Line 189 reads
versionLinefrom the staged header atNVENC_HEADERS_INCLUDE, not fromsamplesHeader. That staged header is the pinnedn13.0.19.1release, so it always reportsNVENCAPI_MAJOR_VERSION 13. The guard at Line 192 therefore evaluates!trueand skipscopyFileSyncin the expected case.
The combined effect is that Samples/NvCodec/NvEncoder/nvEncodeAPI.h keeps the legacy 8.1 header. The compiler prefers that quoted include, so the encoder library builds against API 8.1 and fails at runtime with NV_ENC_ERR_INVALID_PARAM, which is the exact failure the comment at Lines 42-45 describes.
Read the version from samplesHeader and run the replacement on every invocation.

Update the native cursor atlas rule. It contradicts the new behavior.
Lines 205-207 state that the CUDA route must NOT draw the native cursor atlas when overlay layers are present. The audit document (docs/benchmarks/cuda-pipeline-audit-2026-09-08.md Lines 33-35) and tiledOverlayNative.test.mjs ("keeps a native cursor atlas visible above a renderer overlay sidecar") say the reverse. The atlas is suppressed only when the browser bakes the cursor into the sidecar. Lines 259-261 of this file also limit the atlas to that case. This file is durable guidance for agents, so the contradiction can cause regressions. Rewrite the sentence to say that the CUDA route skips the native cursor atlas only when the renderer baked the cursor into the sidecar. Also fix the corrupted character "�" at Line 103.

Cache only successful probe results in withMetadataProbeCache.
withMetadataProbeCache stores every compute() result for an existing file. That includes the failure values:
probeMediaDurationSecondsreturns0when ffmpeg times out (5 s) or prints noDuration:line.probeVideoStreamDurationreturnsnullon any ffprobe error.
A transient failure is then served from the cache until the file's size or mtime changes. Examples are a timeout under load, or a file that is still being finalized when its mtime has already settled. Callers keep getting duration 0 or null, and companion-audio sync and diagnostics use those values.
The test name "never caches missing files or failed probes" covers only missing files.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
The prewarm teardown does not wait for the probe process to exit, and the strict HEVC branch cannot run.
cancelInFlightCapabilityOnlyPrewarms() (electron/ipc/export/native-video.ts:211-232) is synchronous. It sends SIGKILL, catches every error itself, and returns a count. As a result:
awaitresolves at once. The child can still hold its NVENC session whenspawn(ffmpegPath, …)runs. The comment "no in-flight capability probe is still running" is therefore false.- The
catchblock never runs. ThenoCpuFallback:truehard fail for HEVC Hardware is dead code.
Make the helper return a promise. The promise must resolve on each child's exit/close event, with a bounded timeout, and reject on timeout. Then the strict branch works as documented.
export async function cancelInFlightCapabilityOnlyPrewarms(timeoutMs = 2000): Promise<number> {
const children = [...activeCapabilityOnlyPrewarmChildren];
activeCapabilityOnlyPrewarmChildren.clear();
await Promise.all(children.map((child) => new Promise<void>((resolve, reject) => {
if (child.exitCode !== null || child.signalCode !== null) return resolve();
const timer = setTimeout(() => reject(new Error("prewarm teardown timed out")), timeoutMs);

Reject frame-port writes after finalization starts.
finishingNativeVideoExportSessions is checked only when a new port attaches. handleNativeVideoExportFramePortMessage checks session.terminating, then accepts frames and enqueues writes. An already attached port can therefore enqueue a frame after finalization captures the current session.writeSequence. The finish handler can end FFmpeg stdin before that write runs, causing write after end.
Store the finishing state on NativeVideoExportSession, or expose a predicate for it. Check that state in handleNativeVideoExportFramePortMessage before accepting the frame.

Pass the codec to resolveExportBitrate. Without it, HEVC exports get the H.264 bitrate cap.
resolveExportBitrate accepts codec and passes it to customBitrateMbpsToBps(customMbps, codec) and getCodecAutoBitrateCapBps(codec). This call does not pass codec. HEVC exports therefore use the default codec cap, not the 70 Mbps H.265 cap that the PR objectives require. This applies to both Auto mode and Custom mode. The same wrong value also goes into smokeResolvedSettings.bitrateBps.

Add each sprite's texture and anchor to getSpriteStateSignature.
The docstring says that an identical signature produces identical pixels. This is false when the cursor type changes for a cursor-pack style:
update()sets a different texture and anchor oncustomCursorSprite(getCursorPackStyleAsset(style, spriteKey)).- If both assets have the same
aspectRatio, the position, rotation, width, and height do not change.
The signature is then identical, and the cursor-sprite export reuses the previous frame. The output shows the arrow where the pointer should be, or the reverse.

Stop reusing a frame when the content signature is unknown (null).
The reuse guard only rejects undefined. FrameRenderer.captureCursorSpriteFrame passes null when cursorOverlay is missing or has no getSpriteStateSignature. The capturer stores contentSignature ?? null. Two frames with a null signature and the same ROI therefore compare equal. The capturer then reuses the previous pixels. The interface comment defines null as "unknown", so "unknown" is treated as "unchanged". The fix is to treat both null and undefined as "do not reuse".

Update the reuse guard in the frame-capture method so it only reuses pixels when
contentSignature is known; treat both null and undefined as unknown and prevent
reuse in either case. Keep the existing signature and ROI comparisons unchanged.

Compare the reuse ROI against the recorded ROI size, not the render-texture size.
record.width and record.height hold renderTexture.width and renderTexture.height. ensureRenderTexture keeps a texture that is larger than the current ROI, and it applies maxSpriteWidth/maxSpriteHeight. After the texture grows once, previous.width === roi.width is false for every smaller ROI. This also happens whenever the fixed strip size differs from the clamped roiOverride. Reuse then never happens in the cursor-at-rest case, and every frame does a full ROI render and readback. Store the ROI dimensions on the record and compare against those values.

Update the previous-record reuse check to compare the recorded ROI dimensions
with roi.width and roi.height, rather than comparing the render-texture
dimensions. Store the ROI dimensions on each CursorSpriteFrameRecord and
populate them whenever records are created or reused, while preserving the
existing texture dimensions for rendering.

PixiJS 8.14.0 Container worldTransform getGlobalTransform updateTransform source
💡 Result:
For **PixiJS 8.14.0**, `Container.getGlobalTransform()` is implemented in the global/local mixin, while `Container.ts` defines the class. The version-pinned source is [toLocalGlobalMixin.ts](https://github.com/pixijs/pixijs/blob/v8.14.0/src/scene/container/container-mixins/toLocalGlobalMixin.ts) and [Container.ts](https://github.com/pixijs/pixijs/blob/v8.14.0/src/scene/container/Container.ts). ([github.com](https://github.com/pixijs/pixijs/blob/v8.14.0/src/scene/container/container-mixins/toLocalGlobalMixin.ts))
**Key distinction:** `getGlobalTransform(out, skipUpdate)` can recalculate the global transform chain unless `skipUpdate` is `true`. `worldTransform`, by contrast, is the cached transform and may not reflect recent changes until transforms are updated. For an up-to-date matrix, use:
```ts
const matrix = container.getGlobalTransform();
```
The v8.14.0 mixin’s `toGlobal()` calls `getGlobalTransform(...)`; it also documents `skipUpdate` as skipping transform updates. ([github.com](https://github.com/pixijs/pixijs/blob/v8.14.0/src/scene/container/container-mixins/toLocalGlobalMixin.ts))
`updateTransform()` was removed from the v8 scene-object API; it is not the v8 way to force an update. ([pixijs.com](https://pixijs.com/8.x/guides/migrations/v8?utm_source=openai))

Refresh the cursor transform before the ROI render.
In Pixi.js 8.14.0, reading worldTransform does not recalculate the changed scene-graph transform chain. The streaming path supplies roiOverride, so it bypasses bounds calculation and reads the cached transform before the ROI render. During zoom, the cursor can be offset or clipped.

Update the ROI cursor-rendering path to refresh the transform chain before
building the cursor sprite render transform; do not rely solely on the cached
cursorContainer.worldTransform during zoom. Use
cursorContainer.getGlobalTransform where available, retaining the cached
transform as a fallback, and pass the refreshed transform to
buildCursorSpriteRenderTransform.

Hey team — I've been using Recordly daily for a while and wanted to get some of the bigger performance wins I kept hitting upstream. This PR is a whole-stack pass on the MP4 export path, with the main goal of making GPU export actually fast and giving us H.265 as an option.
What I tested on:
On that machine, full-canvas exports that were previously stuck at ~14 FPS on the CPU path now hit ~150 FPS through the new CUDA compositor. That's not a typo. The bottleneck shifted from "renderer pushing raw frames over IPC" to "the encoder doing real work."
What's in here:
hevc_nvenc) in addition to H.264.Why H.265: same visual quality at roughly half the file size. Modern platforms and hardware handle it fine, and it's ideal for anything going to social media where storage/bandwidth matters.
Known next steps I didn't want to lump in here:
This is a big diff, but it's been run through the full vitest suite and
tsc --noEmitclean. Happy to split or rebase however makes review easier.Summary by CodeRabbit
.m4asupport, pending media handling, and longer export extensions.
