 1. when muxing mpeg-ps(i use -f svcd,all streams are -c copy), the scr is
 always begin with 28616 either than 0. and according to 18138-2,the
 scr_ext seems to start with 299.

 2. when the video source(vbv_buffer=224k,bitrate=9000k,CBR) is Main at High
 or Main at High 1440,
 it says
 buffer underflow
 packet too large, ignoring buffer limits to mux it.

 3. there isn't a option "sys_header only in first packet"
  i read the sorce and there is only "sys_header in every N packet"
