不好意思,打错了,是VFW。。。。。
MMG出来的信息是
You are trying to put AVC/h.264 video from an AVI or a similar VfW (Video for Windows) compatible source into a Matroska file in the so-called 'VfW compatibility mode'. Please note that this is not the official way to store AVC/h.264 video in Matroska. Therefore proper playback of such files cannot be guaranteed, and we strongly urge you to use the native Matroska-mode.
我刚接触这方面的东西。。。。。很多都不明白。。请指教了,谢谢!
