AM335x ARM Cortex-A8 performance drop opus 1.1
Hi, Just to clear things up... So 1.1 has some new analysis code that increases the amount of CPU. When building as floating point (which you appear to be doing, right?), the new code is enabled at complexity 7 and up (opusenc defaults to complexity 10 IIRC). This is why you've been seeing an increase in the CPU time. In version 1.0.x, complexity 5-10 are the exactly the same for music.

AM335x ARM Cortex-A8 performance drop opus 1.1

At the moment I dont no why, but I see that 1.1 is much slower in encoding. Are there any default changes, that I missed and could explain this? Normaly I suggested a better performance with 1.1 and the ARM
