[vorbis] Odd broken oggs ...

[Hugo van der Merwe]

I have a CD ripped with RC2, ogginfo from 1.0 claims they are all
"broken". ogg123 also goes a little wild with them. I'll experiment a
little more, maybe play with xmms, etc. RC3's ogginfo do not see anything
wrong with them... an example:

---------- ogginfo 1.0

New logical stream (#1, serial: 2aab0567): type vorbis
Vorbis headers parsed for stream 1, information follows...
Version: 0
Vendor: Xiphophorus libVorbis I 20010813 (1.0 rc2)
Channels: 2
Rate: 44100

Nominal bitrate: 128.000000 kb/s
Upper bitrate not set
Lower bitrate not set
User comments section follows...
 <snip>
Vorbis stream 1:
        Total data length: 3527030 bytes
        Playback length: 3m:32s
        Average bitrate: 132.944968 kbps
Logical stream 1 ended
Warning: Hole in data found at approximate offset 3530268 bytes.
Corrupted ogg.

<p>---------- ogginfo rc3

erial=715851111
header_integrity=pass
 <snip>
vendor=Xiphophorus libVorbis I 20010813
version=0
channels=2
rate=44100
bitrate_upper=none
bitrate_nominal=128000
bitrate_lower=none
stream_integrity=pass
bitrate_average=132758
length=212.240000
playtime=3:32
stream_truncated=false

total_length=212.240000
total_playtime=3:32

-----------------

What could cause this? (Other than physical data loss.) This file never
went anywhere. Ripped with grip, directly to a local hard drive...
possibly a bad sector though, hard drive was replaced, was still under
warranty. Didn't think the oggs were affected, and these "holes" are
present in all the oggs from that CD..

Thanks,
Hugo van der Merwe
