[Live-devel] MPEG4 elementary video

[moonheart]

Scott Hays,hi£¡

     Can you tell me the format of  the MPEG4 elementaty stream video you used in you system?
     As far as I know , MPEG4 video part can be obtained by Divx or Xivd  or other codec.
     You can print out the header of you stream and find the format information .
     I found that live stream server can only deal with the xivd MPEG4 video ,and if you use
     a divx MPEG4 video stream , a "segmentation error" will appear and the server will shutdown at once.
