基于mplayer.ocx插件实现的VB播放器，基于Directshow+DC DSP实现音乐可视化频普，EQ，声道合成，使用VMR9实现视频渲染（亮度，对比度，饱和度，色调）。之前因使用C的一个COM DLL，需要注册，部分电脑不注册无法加载。现去掉DLL，内部完成加载和删除FILTER完成。实现WMP可视化效果。-The mplayer.ocx plug-in implementation of VB player based on Directshow+DC DSP music, visual spectrum, based on the EQ, sound synthesis, using VMR9 to realize video rendering (brightness, contrast, saturation, hue). Before a COM from the DLL, using the C need to register, part of the computer not registered cannot load. We removed the DLL, interior finish loading and deleting FILTER. Implementation of WMP visualization.
