I received feedback off-list, so I am sending my notes to the list too. I
removed the other sender's comments, since they were not public.

I rarely touch Windows. This is under NetBSD/i386 1.6.2_STABLE. I just
check and behaves same under Linux too.

[input not seekable]

That's what it looks like.

ktrace shows:

4986 ogg123   CALL  lseek(0,0,0xffffffff,0xffffffff,0)
4986 ogg123   RET   lseek -1 errno 29 Illegal seek
4986 ogg123   CALL  lseek(0,0,0,0,0x1)
4986 ogg123   RET   lseek -1 errno 29 Illegal seek
4986 ogg123   CALL  lseek(0,0,0xffffffff,0xffffffff,0)
4986 ogg123   RET   lseek -1 errno 29 Illegal seek
4986 ogg123   CALL  lseek(0,0,0,0,0x1)
4986 ogg123   RET   lseek -1 errno 29 Illegal seek
4986 ogg123   CALL  lseek(0,0,0xffffffff,0xffffffff,0)
4986 ogg123   RET   lseek -1 errno 29 Illegal seek
4986 ogg123   CALL  lseek(0,0,0,0,0x1)

But when using "ogg123 -v - < file.ogg" ktrace does not show any "Illegal
seek" problems.

[ogginfo]

It appears normal.

[http input]

Works fine:

rainier:~/audio$ grep http /etc/inetd.conf

Thanks for the feedback.
