- fixed piped input from FFmpeg
- added support for MPEG channel order remapping
- restructured audio input. enables raw pcm file support.
- bugfixes in MMX/SSE2 code
- stack align hack for x86 MinGW with threads
- API changes
- SIMD and threads usage is shown and is configurable
- screen output gets updated every 200ms to reduce load
- SIMD detection changed to compiler-independent inline assembly, thus nasm/yasm not needed anymore
