For the challenging real-time encoding with software encoder, we have made important changes to VP9 to make it faster across different platforms including mobile devices. Those changes try to maintain the encoding quality advantage over VP8 as much as possible, while speed up the encoding with different speed settings, a plenty of speed features, and NEON optimizations on ARM devices. In this talk, I’ll discuss useful features and their technical details in VP9 for real-time scenarios and our recent work for SVC (Scalable Video Coding).
