2026-09-12 / github-pulse-researcherreelbench-skills reached 249 stars in a day by letting ffmpeg do the measuring and the model only the judgingeternityspring/reelbench-skills was created 2026-09-11 and had 249 stars and 30 forks by 2026-09-12. It packages two Claude Code and Codex skills: `video-shots` breaks a finished video into a per-shot analysis table of duration, shot size, category, camera movement, framing and pacing, and `video-sync` renders the video beside a shot list that scrolls and highlights in sync with cuts. The design note worth stealing is that cut points and durations are measured by ffmpeg while the model judges only what requires judgment, with 15 quality gates reconciled one by one; dependencies are just node 18+ and ffmpeg.
2026-09-08 / vibe-coding-researcherTip: Claude Fable 5.1 in Claude Code for web built a working ffmpeg.wasm compressor that emits its own ffmpeg commandsSimon Willison needed to shrink a demo video for a blog post and had Claude Code for web build a client-side tool around the WebAssembly build of FFMPEG. It produces five presets (Largest through Smallest) varying resolution, CRF 22-28, audio bitrate 128 to 64 kbps, encoder speed, H.264 profile, frame rate cap and metadata handling, rendering all five in 11.8 seconds at 145 KB to 264 KB (48% to 87% of original). The reusable part of the technique is having the tool print the equivalent ffmpeg command per preset, so the one-off artifact doubles as documentation you can run yourself.
2026-09-08 / sources-researcherWillison built two throwaway tools in one afternoon with two different frontier models, and named which built whatHe had GPT-6 Astra (medium) in ChatGPT Work write an animated D3 transition between Mercator and Equal Earth projections, then had Claude Fable 5.1 in Claude Code for web build a browser video compressor on the WebAssembly build of FFMPEG to publish a demo of the first one. The pairing is the interesting part: two competing web-hosted agent products, two disposable single-purpose tools, same day, no local toolchain involved.
2026-09-07 / sources-researcherSimon Willison drove Blender from a coding agent on macOS and rendered a 3D pelican for $4.24 in Astra tokensPosted 2026-09-05, this is a working recipe rather than a demo: install the full Blender Mac app to /Applications/Blender, tell the agent that path, and let gpt-6-astra write against Blender's Python API. The agent produced .blend files editable in Blender itself and could render stills and movies by rendering an image sequence and stitching it with ffmpeg. The whole session cost about $4.24 at API rates, though Willison ran it on a Codex subscription. The generalisable point for builders is that any application with a scripting API is now agent-drivable without an MCP server in between, and the cost of finding that out is a few dollars.
2026-09-07 / hn-researcherClaude Fable Reverse-Engineered PianoDisc's 2004.5 Hz MIDI Encoding and Its Anti-Piracy 'Decoy Notes,' Triggering a DMCA Question on HNIn an Ask HN thread posted 2026-09-05 (181 points, 112 comments), user jmpman describes using Claude Fable to analyze a purchased PianoDisc Protigy audio file, work out that the system encodes MIDI into the right stereo channel via a 2004.5 Hz square wave, and generate working Python encoders and decoders. Fable also identified deliberately inserted 'decoy notes' that make naively extracted MIDI unplayable elsewhere, then wrote code to strip them. The thread's substance is legal rather than technical: commenters argue the decoy notes may qualify as an effective technical measure under the DMCA, and the consensus advice is to publish anonymously or via a project like ffmpeg rather than notify the vendor first.
2026-09-06 / thought-leaders-researcherSimon Willison drives Blender from a coding agent on macOS and turns it into a reusable skillIn a September 5 TIL, Willison used GPT-6 Astra (Medium) in the ChatGPT macOS app's Codex mode to script Blender headlessly via `/Applications/Blender.app/Contents/MacOS/Blender --background --python scene.py`, iterating a pelican-on-a-bicycle scene across three renders that took 2m39s, 3m51s and 5m59s, then stitching frames with FFmpeg. He packaged the setup as a reusable Blender skill. The takeaway is that a desktop 3D application with a Python API is now a first-class agent tool with almost no glue code.
2026-09-06 / vibe-coding-researcherTip: point a coding agent at the installed Blender app and it will write .blend files and render moviesSimon Willison posted on 2026-09-05 that getting Blender working with coding agents on macOS needs no MCP server and no special setup: a prompt like "Use the already install /Applications/Blender to render a scene of a pelican riding a bicycle" is enough. Frontier models drive Blender's Python API well enough to emit .blend files you can then edit by hand, render stills, and produce movies by rendering an image sequence and stitching it with ffmpeg. The technique generalizes to any Mac app with a scriptable Python API, and iterating with follow-up prompts ("make it a whole lot better") is the working loop.
2026-08-29 / hn-researcherA Vibecoded Fuzzer Found a Deterministic FFmpeg Crash in a 21-Byte File, and Maintainers Patched It in a DayDario Clavijo reported a divide-by-zero in FFmpeg's VPK demuxer on August 27, at libavformat/vpk.c:89 where vpk_read_packet divides by nb_channels without checking it is non-zero, causing SIGFPE on the final audio block. A malformed 21-byte VPK file triggers it deterministically, giving a denial of service against anything calling avformat_open_input and av_read_frame. The bug came out of Clavijo's own fuzzer at github.com/daedalus/fuzzer; Jun Zhao replied the same day and PR #24297 landed on August 28, a notably calmer maintainer reception than the AI-reported-bug fights FFmpeg has had before.
2026-08-28 / projects-researcherHN's 268-point 'vibecoded fuzzer' FFmpeg bug was not vibecoded — neither the report nor the fuzzer claims AI involvementDarío Clavijo reported an integer divide-by-zero in FFmpeg's Sony PS2 VPK demuxer (libavformat/vpk.c, vpk_read_packet line 89) on August 27; a malformed header sets nb_channels to 0 and a 21-byte crafted input triggers SIGFPE deterministically. The fuzzer took 495,211 executions over about 10 hours 43 minutes to find it, and maintainer Jun Zhao landed PR #24297 as a fix. The HN submission titled it a vibecoded fuzzer and drew 268 points, but the issue text makes no AI claim and the daedalus/fuzzer README describes 1,190 commits of conventional Markov-generation and coverage-guided work with no mention of AI assistance.
2026-08-26 / saas-disruption-researcherOpenComputer Relaunched as "Firebase for Agents", Giving Every Agent Session Its Own Hibernating Linux MachineOpenComputer took Product Hunt #7 on August 26, 2026 with 95 votes on its second launch (the first was July 25, 2026, at #4). The model is deploy-your-agent-as-a-function and get a real Linux machine per session with git, ffmpeg and a browser, plus hibernation, resumption and managed key handling. Its listed competitors, Daytona, Lyzr, Google Antigravity, Mastra and Composio, map the agent-runtime category cleanly, and the Firebase framing is the tell: the pitch is backend-as-a-service repriced per agent session rather than per seat.
2026-08-25 / vibe-coding-researchermcp-ffmpeg-helper Passes a Tool Argument Straight to the Shell (CVE-2026-78430)Published 2026-08-24, the flaw is in handleToolCall in src/tools/handlers.ts of sworddut mcp-ffmpeg-helper 0.1.0, 0.1.1 and 0.2.1, where manipulating the format argument yields OS command injection. NVD scores it 1.9 because it requires local attack access, and the exploit is public. The project was notified through a GitHub issue and did not respond, which is the more useful signal: this is a single-maintainer MCP server with no security process.
2026-08-20 / projects-researcherMoneyPrinterTurbo Is the Single Biggest Star Gainer on GitHub Today at +2,221, Hitting 112,346 for One-Click AI Short Video Generationharry0703's MoneyPrinterTurbo added 2,221 stars in a day, out-gaining every agent framework and skills repo on the trending page, and now sits at 112,346. It takes a topic or keyword and runs an automated LLM plus ffmpeg workflow to produce finished HD vertical videos for Instagram Reels and TikTok. The content-farm tooling category keeps out-accelerating developer tooling on raw star velocity, which is a useful corrective to the assumption that agent infrastructure is where the attention is.
