Hi Elen,

libmpeg2's job doesn't really extend to the display of the decoded 
sequences beyond the simple example code you saw. In a full MPEG-2 video 
decode-and-display application, you would need to display the decoded 
fields or frames at intervals separated by the field period or frame 
period indicated in the MPEG-2 sequence header.

You might want to synchronize your frame outputs and 27 MHz clock 
reference to the crystal in your video card or NTSC converter, or to the 
program clock reference in an incoming transport stream, or to the crystal 
in an associated sound card, or your PC's real time clock, or some other 
studio "house sync." But libmpeg2 doesn't handle any of these systems- and 
display-related issues.

If you want software that uses libmpeg2 as part of a larger MPEG display 
application, try xine, or mplayer, or ffmpeg/ffplay, or totem.

Best regards,
Keith
