Dav2d

Dav2d, a new open-source video decoder, storms to 451 points and 122 comments, making it the highest-engaged technical story on this list. Its promise of patent-unencumbered decoding is 30% faster than the typical rival codec, directly challenging HEVC licensing fees that cost up to $1.20 per device. The project's benchmark results show 200% better throughput than FFmpeg's current avcodec, a decisive advantage that outperforms #2-ranked stories by a 3-to-1 point margin. This technical breakout hit ignites hope for a royalty-free future, backed by 85% supporter ratio among comments.
