Read an article yesterday about the H.264 codec increasing their licensing fee by an astronomical amount.And as always, my first shot was how hard could it be to try and build a codec which could be that efficient.I've personally been on a drive to improve my ability to one-shot complex features, products, or make even surgical changes. It's been a few months since I've been doing that, and honestly, results have been great for both work and work/life balance.This was a fun experiment. It burned through tokens, but it helped me identify some more improvements I could make to my one-shot agent teams/swarms, notably in the area of brevity and creating a testing rubric when dealing with domains I don't have prior knowledge in.Ultimately, I did not achieve the compression that I hoped I would, but it was fun seeing the swarm discuss it amongst themselves.

Could you build this?
No Modern video codecs involve cutting-edge digital signal processing, spatial/temporal motion estimation, entropy coding, and hardware-level performance engineering.
What it would actually take: Building an H.264-level video codec requires implementing complex algorithms like Discrete Cosine Transforms (DCT), intra/inter-prediction, rate-distortion optimization (RDO), and Context-Adaptive Binary Arithmetic Coding (CABAC) in low-level languages (C/Assembly) with SIMD vectorization. The core challenge is achieving competitive compression efficiency without prohibitive compute latency, requiring deep specialization in information theory and video compression standards.
