--- Comment #6 from Nick Kallen <socialmediamaster9000 at gmail.com> ---
Here are some logs indicating a bad next_pts overwriting a "good" pts:

An alternative solution is:

      if (parse->priv->next_pts != GST_CLOCK_TIME_NONE)
        GST_BUFFER_PTS (tmpbuf) = parse->priv->next_pts;

I don't exactly know why there are four identical PTS' in a row, but at this
point, setting them to none seems to make them worse.
