Vorbis - Feb 2002 - Seeking in a saved stream; or,Why isn't thatsucker valid?

because there's not another packet?)  Then it

Ogginfo behaved nice to me :-) At least once. But as stated earlier in this
thread it shouldn't be trusted too much.
Just for reference, I saved a streamed ogg and got this:

---------------------------------
E:\>ogginfo radio4.ogg
filename=radio4.ogg

erial=1037942235
header_integrity=pass
vendor=Xiphophorus libVorbis I 20011217
version=0
channels=2
rate=44100
bitrate_upper=none
bitrate_nominal=96016
bitrate_lower=none
stream_integrity=pass
bitrate_average=65
length=182692.561270
playtime=3044:52
stream_truncated=true

total_length=182692.561270
total_playtime=3044:52                           <----------------- what
winamp also thinks.

E:\>
----------------------------------

While this looks allright, there appears to be some errors:

Obviously playtime/total lenght is way up. (true time is 1.50)
Average bitrate was reported 96kbps in winamp _when recording_, but 88kbps when
playing.
(Filesize is 1 501 963 bytes.) 

Seeking causes the track to restart except when seeking to the very end, which
will play the last piece (packet?) of the
stream. Odd.

On two other (much shorter) samples, oggenc went wild and filled the console
just like Stephen reported. Guess I was
lucky.

What do you think? Could the problem be Winamp specific? I'm using v1.17d
vorbis plugin for winamp.

Oh, heh, ogginfo is forgetting to subtract the start time.  Come to
think of it, I need to check vorbisfile to make sure that it's obeying
its docs.

I have observed time-of-stream problems with ones I've obtained with wget. 
That's a nasty stream, of course, but it plays just fine.

Any chance that this could be a bug in the "save stream" option in
Nullsoft
Vorbis Decoder (v1.17b)??

I found out that it wasn't luck after all. Apparently winamp fixes some of
the header if you press Alt+3 (to bring up file
info) and press 'update'. After this ogginfo don't panic anymore on
that .ogg file. I bet this's what I did.
