ffmpeg से वीडियो में सीन कट ढूँढकर उन्हीं बिंदुओं पर फ़ाइलें कैसे बाँटें

·6 views

एडिट किए वीडियो में कट पहचानने के लिए ffmpeg का scene फ़िल्टर आमतौर पर पर्याप्त माना जाता है, पर यह लेख दो अनसुलझे सवाल उठाता है: सही threshold कैसे चुनें और कटों पर ही फ़ाइलें कैसे बाँटें। लेखक ने ffmpeg के अंदरूनी scoring तरीके को Python में दोबारा बनाकर उसे एक NASA launch वीडियो पर मापा है। विश्लेषण में दिखाया गया है कि showinfo के नतीजे stderr में आते हैं, न कि stdout में। हर फ़्रेम का score उसके और पिछले फ़्रेम के बीच औसत अंतर के बदलाव के आधार पर तय होता है, जिससे कैमरा शेक और असली कट में फ़र्क होता है। Y plane को yuv420p से लेना सटीक नतीजों के लिए ज़रूरी बताया गया है।

LinkDigest reads top Xiaohongshu comments from share links without an account

Xiaohongshu offers no public comments endpoint, and its web page only expands comments after login. The share link copied from the app opens a public page that embeds up to five top comments, each with up to three replies. The LinkDigest service reads these in the same request as the note, requiring no Xiaohongshu account or cookies. The approach is limited: it returns only top comments and reply excerpts, never the full thread or commenter identities. Douyin videos return no comments because their embed player serves none.

Verifying Warranty Cards On-Chain: A Token-2022 Soulbound Receipt Checker

A repair-shop scenario illustrates the need to confirm whether a customer's warranty card is genuine without relying on screenshots or the holder's word. The article presents a verifier that checks a soulbound Token-2022 card using only public chain data, applying eight checks covering mint ownership, one-of-one supply, non-transferability, metadata location, issuing authority, warranty validity, order matching, and holder ownership. The verifier is a pure function over raw account data, making it reusable in servers, wallets, or agents. It returns every individual check result rather than a simple pass or fail, so staff can see exactly which requirement failed. The author notes the code is an unaudited, devnet-only educational example and that actual warranty decisions still depend on shop policy and consumer law.

Five Practical Ways to Improve Online Form Validation in JavaScript

A DEV Community article outlines five approaches developers can use to make web form validation more effective without adding needless complexity. It recommends using built-in HTML input types and the required attribute to handle basic checks before writing extra code. The piece also urges specific, actionable error messages so users know exactly what to correct. JavaScript can supplement HTML validation for additional checks, though the author stresses that client-side validation does not replace server-side validation. The article further advises making forms accessible through connected labels, clear instructions and visible focus indicators, and keeping forms short by removing unnecessary fields.
