 At ffplay.c:3004 there is a code block as below:

 {{{
         if (!is->paused &&
             (!is->audio_st || (is->auddec.finished == is->audioq.serial &&
 frame_queue_nb_remaining(&is->sampq) == 0)) &&
             (!is->video_st || (is->viddec.finished == is->videoq.serial &&
 frame_queue_nb_remaining(&is->pictq) == 0))) {
             if (loop != 1 && (!loop || --loop)) {
                 stream_seek(is, start_time != AV_NOPTS_VALUE ? start_time
 : 0, 0, 0);
             } else if (autoexit) {
                 ret = AVERROR_EOF;
                 goto fail;
             }
         }
 }}}

 When using '''stream_seek''' with '''start_time''', it doesn't add the
 stream start time just like code at ffplay.c:2896:

 {{{
         timestamp = start_time;
         /* add the stream start time */
         if (ic->start_time != AV_NOPTS_VALUE)
             timestamp += ic->start_time;
         ret = avformat_seek_file(ic, -1, INT64_MIN, timestamp, INT64_MAX,
 0);
 }}}
