Node Ytdl Core
node-ytdl-core este o bibliotecă JavaScript pentru Node.js concepută pentru a extrage metadate și a face streaming de conținut video și audio de pe YouTube. Servește ca un downloader media și fetcher de stream-uri, permițând utilizatorilor să preia detalii video și date media din surse remote.
Biblioteca oferă capabilități specializate pentru extracția video, inclusiv capacitatea de a parsa URL-urile media pentru identificatori unici și de a analiza formatele disponibile. Permite selectarea și filtrarea fluxurilor video și audio specifice pe baza criteriilor de calitate și rezoluție.
Proiectul gestionează traficul de rețea prin evitarea limitelor de rată și gestionarea cookie-urilor de autentificare. Utilizează fluxuri lizibile (readable streams) pentru piping-ul datelor și suportă cereri de tip byte-range pentru a prelua segmente specifice ale fișierelor media.
