Challengers Libvpx [upd] [ HOT ]

This paper provides a good starting point for exploring the challenges and opportunities in optimizing libvpx for real-time applications. The results and insights presented can be used to guide further research and development in this area.

AV1 vs. VP9: A Performance and Compression Comparison for Modern Video Coding Why: Directly benchmarks libvpx (VP9) against libaom-AV1 (the intended successor, but also a challenger in terms of compression efficiency). Shows where libvpx still wins on speed vs. AV1’s better bitrate. Findings: libvpx remains faster but is outperformed in compression by 20–30% by AV1 at similar perceptual quality. Venue: IEEE ICIP or MMSys (multiple versions exist). challengers libvpx

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. This paper provides a good starting point for
