It falls into an infinite loop when ogg_pcm_seek is called for the ogv file.

I try to read vorbis in the ogv file (theora file) by using vorbisfile(libvorbis 1.2.0). The ogv file was made with ffmpeg2theora.

Reading succeeded. However, processing doesn't return when ov_pcm_seek(&vf, 0) is called. It seems to fall into an infinite loop by _get_prev_page of vorbisfile.c.

Cannot ov_pcm_seek be used for the ogv file?
