Привет!!

По-моему у тебя некорректно парсится #EXT-X-DISCONTINUITY: в reader.go

    case !state.tagInf && strings.HasPrefix(line, "#EXTINF:"):
        state.tagInf = true
        state.listType = MEDIA
        params := strings.SplitN(line[8:], ",", 2)
        if state.duration, err = strconv.ParseFloat(params[0], 64); strict && err != nil {
            return errors.New(fmt.Sprintf("Duration parsing error: %s", err))
        }
        title = params[1]
    case !state.tagDiscontinuity && strings.HasPrefix(line, "#EXT-X-DISCONTINUITY"):
        state.tagDiscontinuity = true
        state.listType = MEDIA
    case !strings.HasPrefix(line, "#"):
        if state.tagInf {
            p.Append(line, state.duration, title)
            state.tagInf = false
        } else if state.tagRange {
            if err = p.SetRange(state.limit, state.offset); strict && err != nil {
                return err
            }
            state.tagRange = false
        } else if state.tagDiscontinuity {
            state.tagDiscontinuity = false
            if err = p.SetDiscontinuity(); strict && err != nil {
                return err
            }
        } else if state.tagProgramDateTime {
            state.tagProgramDateTime = false
            if err = p.SetProgramDateTime(state.programDateTime); strict && err != nil {
                return err
            }
        }

В блоке case !strings.HasPrefix(line, "#"), если до этого выставлено в true два флага - tagInf и tagDiscontinuity, Discontinuity не выставится, т.к. ты используешь if else вместо if.

Я это обошел, проставив перевод строки после чанка с Discontinuity, чтобы зайти в вышеназванную секцию два раза!

Может это по стандарту надо ставить перевод строки?
