if 1000 frames are in the bitstream, the decoder should decode all 1000
of them.

firstly, you should attempt to find the missing frames: are they really
being encoded, or is the decoder ignoring them.

the easiest way to do this, is to add some print statement in your
encoding program, to display the frame length (bytes) for each call to
XVID_ENC_ENCODE. do the same to the decoding program, but display the
frame lengths that are decoded by XVID_DEC_DECODE.
run your encoder and decoder, and then compare the output.
