I compared DVD SW decoding of Jarvis vs. Krypton vs. Leia on my slow BRAVIA with quad core ARM Cortex A53 (@1.1GHz) as some people (including me) are witnessing a major regression with SW decoding in Leia.
Jarvis
Playback mostly smooth, no frame drops/skips
Krypton
Playback mostly smooth, no frame drops/skips, dramatic increase in CPU usage compared to Jarvis
Leia
Playback totally jerky, frames are dropped and skipped like crazy, dramatic increase in CPU usage compared to Jarvis
Jarvis
Playback mostly smooth, no frame drops/skips
Code:
User 20%, System 14%, IOW 0%, IRQ 0%
User 93 + Nice 1 + Sys 65 + Idle 302 + IOW 0 + IRQ 0 + SIRQ 0 = 461
