Peliculla: Your own TV channel from a playlist — on a Mac, for $9.99

Hey Product Hunt! 👋 I'm Eduardo, a solo dev from Brazil. Peliculla started with a stubborn question: why can't a Mac just open an MKV? Answering it took me somewhere unexpected — I ended up building what I believe is the world's first public MediaExtension format reader: a clean-room plugin that teaches macOS itself (QuickTime, Finder, Quick Look) to open MKV, MXF and WebM. Files from ARRI and Sony cameras that macOS never supported now just... open. Then the app grew around it. A real 16-bit color grading pipeline, because I come from the cinema world. A player with per-track EQ memory. And then transmission: NDI, SRT in & out, RTMP — until one day I realized the playlist + Go Live combo meant anyone could run their own TV channel from a Mac. So that became the product: broadcast for everyone, $9.99, no subscription. It's used on film sets for live color approval, and at home for playing the files nothing else opens. I'll be here all day — ask me anything, especially the hard stuff (why not just VLC? what took the longest? — happy to tell the war stories 🎬)
