Nice to see this (and liking the multiplexed stream support).

Should I be worried by minor differences when round-tripping
through oggenc/oggdec compared to libvorbis 1.1.2?

[ian at prometheus tmp]$ cmp 1.1.wav 1.2.wav
1.1.wav 1.2.wav differ: byte 195111, line 615
[ian at prometheus tmp]$ cmp -i 200000 1.1.wav 1.2.wav
1.1.wav 1.2.wav differ: byte 3, line 1
[ian at prometheus tmp]$ cmp -i 220000 1.1.wav 1.2.wav
1.1.wav 1.2.wav differ: byte 143037, line 318

(en/de-coded using the same version of vorbis-tools,
-q6, haven't tried crossing to find out if the difference
is due to the encode, decode or both)
