How can I determine the length, in seconds, of a Vorbis stream?

Question

How can I determine the length, in seconds, of the Ogg Vorbis stream with libvorbis and/or libvorbisfile?

As far as I can tell, there's nothing in the vorbis_info structure that tells me the length of the stream.

使用较低级别的API，可以使用ov_time_total进行此ov_time_total 。
