"Just as VP8 paved the way for open-source web video, VP9 follows in its footsteps, pushing the boundaries of compression efficiency. Inside the libvpx library, the lineage is clear: a commitment to high-quality, royalty-free video that stays true to its roots while adapting for a 4K future." 2. The Developer Humor (Short & Punchy)
Where the father was proprietary and monolithic, the son is modular and democratic:
As the web moved toward 4K resolution and HDR, VP8 began to show its age. Enter , the "son" of the libvpx family.
If VP8 was the father who broke the ground, VP9 was the son who built the skyscraper. Most of the 4K content you watch on YouTube today is delivered via VP9 through the libvpx framework. The Genetic Legacy: Moving Toward AV1 like father like son libvpx
If libvpx is the son, AV1 is the grandson—a collaboration between Google, Mozilla, Cisco, Netflix, and Amazon (the Alliance for Open Media). AV1 was designed to address the shortcomings of libvpx, specifically its encoding speed and the rising threat of HEVC/H.265.
It contains specific assembly optimizations (SIMD instructions) for virtually every architecture Google touches—x86, ARM, and eventually RISC-V. It reflects Google's "dogfooding" culture: if it runs on a Chromebook or a Pixel phone, it is a first-class citizen in the libvpx build tree.
In the world of open-source video compression, the phrase "" isn't just a metaphor—it’s a technical lineage. When Google released libvpx , the reference software library for the VP8 and VP9 video codecs, it didn't just drop a new tool into the lap of developers; it established a family tree that would eventually redefine how we consume media on the web. "Just as VP8 paved the way for open-source
"The phrase 'like father, like son' perfectly describes the relationship between the codecs housed within libvpx . VP9 inherits the open-source philosophy of VP8 but introduces advanced features like larger block sizes and improved entropy coding, proving that the next generation is always ready to build upon the successes of the first." Key Context for these Texts:
While VP9 kept the core philosophy of its predecessor—being open and royalty-free—it significantly improved the efficiency of the underlying algorithms. Through the libvpx library, VP9 introduced: Allowing for easier multi-threaded decoding.
If the MPEG standards (H.264, H.265) are the aristocratic descendants of the broadcast television era—optimised for hardware decoding in living rooms—then is the scrappy, brilliant progeny of the internet age. To understand libvpx (the library implementing VP8 and VP9), one must look at its progenitor: Google, and specifically the engineering culture of its acquisition, On2 Technologies. Enter , the "son" of the libvpx family
For years, libvpx carried the torch alone. It fought the standards war against Apple’s refusal to support WebM and the industry’s hesitation to adopt a "web-only" codec. The "like father, like son" dynamic here is one of . Much like Google’s persistence with Google+ or Hangouts, libvpx was pushed aggressively into Chrome and Android until it became a de-facto standard for HTML5 video.
The lineage didn't stop with VP9. The lessons learned from the libvpx implementation directly informed the creation of (AOMedia Video 1). While AV1 has its own library (libaom), the DNA of libvpx is visible in its structure. The transition from VP9 to AV1 represents the ultimate "like father, like son" evolution—taking the open-source spirit of libvpx and scaling it to meet the demands of 8K streaming and beyond.
