[vorbis-dev] Vorbis files merging

Good day.

I have one more question.
Is it legal to set granule position of a Vorbis packet, that situated at the
middle
of Vorbis file to a value, that is less, then granule position of the last
PCM sample belonging to this packet?
vorbis-clip.txt says:
"...The decoder then ignores the 'extra' samples.
This behavior is to occur only when the end-of-stream bit is set in
the page (indicating last page of the logical stream)."
Is it true only for end-of-stream marked pages?
Suppose i'd like to select some internal part of a Vorbis file, cut them,
and
save the residuary part to a file. Is the only way to do this (without
decoding-encoding)
make two logical bitstreams in the target file?

Thanks.

Vitaly.
