Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

## FFmpeg in Remotion
|
|
|
|
`ffmpeg` and `ffprobe` do not need to be installed. They are available via the `bunx remotion ffmpeg` and `bunx remotion ffprobe`:
|
|
|
|
```bash
|
|
bunx remotion ffmpeg -i input.mp4 output.mp3
|
|
bunx remotion ffprobe input.mp4
|
|
```
|
|
|
|
### Trimming videos
|
|
|
|
You have 2 options for trimming videos:
|
|
|
|
1. Use the FFmpeg command line. You MUST re-encode the video to avoid frozen frames at the start of the video.
|
|
|
|
```bash
|
|
# Re-encodes from the exact frame
|
|
bunx remotion ffmpeg -ss 00:00:05 -i public/input.mp4 -to 00:00:10 -c:v libx264 -c:a aac public/output.mp4
|
|
```
|
|
|
|
2. Use the `trimBefore` and `trimAfter` props of the `<Video>` component. The benefit is that this is non-destructive and you can change the trim at any time.
|
|
|
|
```tsx
|
|
import { Video } from "@remotion/media";
|
|
|
|
<Video
|
|
src={staticFile("video.mp4")}
|
|
trimBefore={5 * fps}
|
|
trimAfter={10 * fps}
|
|
/>;
|
|
```
