[Info-VCDImager] GNU VCDImager 0.7.5 [unstable] hits the street

[Herbert Valerio Riedel]

...time for a new release ;)

this time the main effort went into writing documentation and
maintaining the webpages... it was great, if someone could do some
spell/grammar checking while reading the docs... ;)

I've investigated a bit more on the scan offset xfile;

I've taken some non-IEC-compliant MPEG2 program stream I had (most of
the svcd mpeg2 streams floating around seem to be that way), which
yielded (output from tests/mpegscan2.c if anyone should care):

cur_ofs  (lba) aps prev_ofs  next_ofs  back_ofs  forw_ofs
00:00.02 (   2) 3  ff:ff.ff  00:00.34  ff:ff.ff  00:08.0a 
00:00.54 (  54) 3  00:00.34  00:00.30  00:00.34  00:08.0b 
00:01.27 ( 102) 3  00:00.30  00:00.3f  00:01.19  00:08.19 
00:02.15 ( 165) 3  00:00.3f  00:00.39  00:02.0d  00:08.1a 
00:02.72 ( 222) 3  00:00.39  00:00.39  00:02.46  00:08.1c 
[..]
01:38.03 (7353) 3  00:00.38  00:00.39  00:07.49  00:02.00 
01:38.60 (7410) 3  00:00.39  00:00.3c  00:07.4a  00:01.12 
01:39.45 (7470) 3  00:00.3c  00:00.21  00:08.01  00:00.21 
01:40.03 (7503) 3  00:00.21  ff:ff.ff  00:08.22  ff:ff.ff 

..the same mpeg, after having been mastered and corrected on the fly
with the new --update-scan-offsets option enabled; and then vcdxrip'ed
again, but now IEC-compliant:

cur_ofs  (lba) aps prev_ofs  next_ofs  back_ofs  forw_ofs
00:00.02 (   2) 3  ff:ff.ff  00:00.54  00:00.02  00:15.72 
00:00.54 (  54) 3  00:00.02  00:01.27  00:00.02  00:16.55 
00:01.27 ( 102) 3  00:00.54  00:02.15  00:00.02  00:17.19 
00:02.15 ( 165) 3  00:01.27  00:02.72  00:00.02  00:18.21 
00:02.72 ( 222) 3  00:02.15  00:03.54  00:00.02  00:19.07 
[..]
01:38.03 (7353) 3  01:37.22  01:38.60  01:24.50  01:40.03 
01:38.60 (7410) 3  01:38.03  01:39.45  01:24.50  01:40.03 
01:39.45 (7470) 3  01:38.60  01:40.03  01:25.33  01:40.03 
01:40.03 (7503) 3  01:39.45  ff:ff.ff  01:25.73  01:40.03 

as you can see, the non-IEC syntax seems to have (unsigned) relative
offsets (which seem to be wastefull, because of half the bits being
zeroed anyway... I wonder how this syntax was caused in the first
place...)

version 0.7.5 (unstable/development)
====================================
2001-06-12

* major documentation improvement
* implemented creation of directories
* new 'update scan offsets' option for fixing scan offset data in
  video mpeg2 streams
* more verbose info on mpeg errors
