skipping %d segments ahead, expired from playlists

static int read_data(void *opaque, uint8_t *buf, int buf_size){   ...         if (v->cur_seq_no < v->start_seq_no) {            av_log(NULL, AV_LOG_WARNING,                   "skipping %d segments ahead, expired from playlists/n",                   v->start_seq_no - v->cur_seq_no);            v->cur_seq_no = v->start_seq_no;        }  ...}

Failed to reload playlist

static int read_data(void *opaque, uint8_t *buf, int buf_size){...reload:if (!v->finished &&            av_gettime_relative() - v->last_load_time >= reload_interval) {            if ((ret = parse_playlist(c, v->url, v, NULL)) < 0) {                av_log(v->parent, AV_LOG_WARNING, "Failed to reload playlist %d/n",                       v->index);                return ret;            }            /* If we need to reload the playlist again below (if             * there's still no more segments), switch to a reload             * interval of half the target duration. */            reload_interval = v->target_duration / 2;        }...}

分析原因： 接收解析m3u8时出错，在parse_playlist里会按http协议请求m3u8，然后解析收到的内容。
