If you tell me your specific angle (e.g., “I need a challenger for real-time streaming” or “I want to show libvpx is outdated”), I can narrow it down to .
Scalable Video Technology for VP9 (SVT-VP9): A Challenger to libvpx in Multi-core Encoding Why: Intel’s SVT-VP9 is a direct challenger to libvpx (both encode VP9). Shows 4–6x speedup on many cores with similar BD-rate. Source: Proceedings of the 12th ACM Multimedia Systems Conference (2021) – “SVT-VP9: A real-time VP9 encoder for many-core systems.”
As future work, we plan to:
Energy-Efficient Video Encoding on Mobile Devices: A Comparison of libvpx (VP9), MediaCodec (H.264), and Hardware Encoders Why: Positions hardware encoders and lightweight codecs as challengers to libvpx in mobile/embedded contexts. Libvpx often loses in power-per-frame. Example: IEEE INFOCOM Workshop on Mobile Video 2019.
While libaom is the "reference" implementation, it isn't always the fastest. Enter (Scalable Video Technology), originally developed by Intel and Netflix. challengers libvpx
The VP9 video codec has become increasingly popular due to its high compression efficiency, which enables efficient video transmission over the internet. libvpx, a reference implementation of VP9, is widely used in various applications, including WebRTC, YouTube, and Netflix. However, optimizing libvpx for real-time applications is crucial to ensure low latency, high quality, and efficient bandwidth utilization. Despite its popularity, libvpx still faces significant challenges in achieving optimal performance, including:
The most direct successor to libvpx's VP9 is , developed by the Alliance for Open Media (AOMedia) . AV1 was built to offer a royalty-free alternative to licensed standards while leapfrogging the compression efficiency of VP9.

Perceptual Quality Assessment of VP9 vs. H.265 and AV1: When Does libvpx Fall Behind? Why: Compares libvpx against x265 and libaom using SSIM, VMAF, and subjective tests. Shows libvpx’s weakness in preserving texture and film grain. Source: Picture Coding Symposium (PCS) 2019.
