[FFmpeg-user] *** drop!

[Roger Pack]

Could anybody explain to me what this message means ("*** drop!")?

here's apparently the associated code from ffmpeg.c:
Thanks!
-r

    nb_frames = FFMIN(nb_frames, ost->max_frames - ost->frame_number);
    if (nb_frames == 0) {
        nb_frames_drop++;
        av_log(NULL, AV_LOG_VERBOSE, "*** drop!\n");
        return;
