More routines have been implemented in SSE for acceleration on older processors
Regs: visiting the "decoder" page I read the following under changes in beta 2:More routines have been implemented in SSE for acceleration on older processors
Its good to see someone who is interested in optimizing their code instead of relying solely on hardware acceleration.
given the difference in CPU use when h/w acceleration is enabled in some of the existing codecs you've got to wonder how much effort goes into optimization these days
