主流H.264编码器对比测试 （MSU出品）

俄罗斯的MSU Graphics & Media Lab (Video Group)出品的H.264编码器性能测试报告。测试了主流的H.264编码器的性能。从测试的结果来看，开源产品x264性能已经超过了商用编码器的性能。

参与测试的编码器有如下几种：

 

• H.264
  DivX H.264
  Elecard H.264
  Intel Ivy Bridge QuickSync (GPU encoder)
  MainConcept H.264 (software)
  MainConcept H.264 (CUDA based encoder)
  MainConcept H.264 (OpenCL based encoder)
  DiscretePhoton
  x264
• Non H.264
  XviD (MPEG-4 ASP codec)
  
  

   

  使用的测试序列：
