I found out that the missing samples problem was due to the decoding part of the code. I have corrected it, however, there is still a problem with the very end of the encoded stream. I am using vorbis_analysis_wrote(&vd, 0) at the end, but ogginfo utility says EOS is not set on stream 1. ov_open_callbacks also returns OV_ENOTVORBIS for the stream I encoded and I cannot play it with my own code, but winamp3 plays it without any problem.
