3.3 Entries Section
===================
Here is part of sample output from the Video CD used above.
1. VCD/ENTRIES.VCD
2. ID: `ENTRYVCD'
3. version: 0x02
4. system profile tag: 0x00
5. entries: 31
6. ENTRY[00]: track# 1 (SEQUENCE[0]), LSN 450 (MSF 00:08:00)
7. ENTRY[01]: track# 1 (SEQUENCE[0]), LSN 482 (MSF 00:08:32)
8. ENTRY[02]: track# 1 (SEQUENCE[0]), LSN 5888 (MSF 01:20:38)
9. ENTRY[03]: track# 1 (SEQUENCE[0]), LSN 8925 (MSF 02:01:00)
...
In the above example, in the first line corresponds the "filename" in
the files section that starts at logical sector number 151. If this
Video CD were in SVCD, XVCD, HQVCD or CVD format that line would
probably say "SVCD/ENTRIES.SVD." As shown In line 5, I made 31 entries
for the Video CD; only the first 4 are shown. Depending on how playback
control is set up you should be able to randomly access up to 31
different playback locations on this Video CD. If you use a media player
like xine and my plugin for it, there is a way jump to the beginning of
each of these entries.
The "track #" and SEQUENCE number are about the same thing, the track
being one more than the SEQUENCE number. Note on line 6 ENTRY[00] is
also at logical sector number 450, the same as AVSEQ01.DAT. In other
words "Entry 0" is the start of the movie.
The minutes, seconds, frames number (MSF 00:08:00) is equivalent to
the LSN number. For those who wonder how to from the MSF to the LSN you
basically multiply the seconds (8) by 75 since there are 75 frames in a
second (note this has nothing to do with how fast this is displayed).
If you get this you get 600 which is a bit large. But that's because
the MSF number 00:00:00 is equal to 150 or the "pregap sector size."
