来个启用了coreave-for-linux的mplayer的pkg

superjet

mplayer -vc coreavc13 (如果codec.conf参照页面上的设置)
同时可以尝试 -correct-pts 或 -no-correct-pts ，在声音等不同步时，可进一步参考下autosync等相关选项

多谢，应该可以成功播放了吧？加了这个-vc coreavc，还要正确的序列号！哈哈。。。。。
看看下面还有什么提议吗？

对比发现CoreAVC DShow H.264 decoder效率并不是像宣传的哪样好！

与[ffmpeg] FFmpeg's libavcodec codec相比较，所占用的内存和cpu一样，后者占用内存稍微略少一一点点。

播放普通H264视频时确实看不出来，只有播放高清视频时才能显现出CoreAVC的高效，比如5分钟800M的BDRip.
CoreAVC也更好地支持多核CPU,ffmpeg始终只会用一个核心。
