By the way, if that XScale chip is IWMMXT capable, it can benefit from SIMD optimizations too. This should probably reduce CPU usage way below 15%. Moreover, IWMMXT is essentially an MMX clone for ARM, so x86 MMX code can be directly converted to it. > Is there a best practices for gstreamer that the plugin is not following? I'm not quite familiar with gstreamer yet, but these performance issues might be really worth investigating...
