Question

我正在使用Bass播放器播放音频。

我如何使用它

首先，我下载清单文件以获取分段音频文件的列表。在看到的Bass背后，下载音频文件。当我寻找内容时，我想重用现有的流。一些它是如何第一次工作，然后在它不工作之后。

-- Load Agg data for the YYYYMM to Teradta
SELECT SUM(loaded_row_count),SUM(error_row_count)
       FROM load_to_teradata (
       ON ( select 
              Cust_id
            , cast(lst_cnf_actvy_dt_tm as date) as lst_cnf_actvy_dt
            , cast(sum(str_cnt     ) as INTEGER) as acct_open_brnch_use_cnt
            , cast(sum(phone_cnt   ) as INTEGER) as acct_open_phn_use_cnt
            , cast(sum(mail_cnt    ) as INTEGER) as acct_open_mail_use_cnt
            , cast(sum(onlnchnl_cnt) as INTEGER) as acct_open_onln_use_cnt
            , cast(sum(mblbnk_cnt  ) as INTEGER) as acct_open_mbl_dvc_use_cnt
            , cast(sum(acctopen_cnt) as INTEGER) as acct_open_trck_chnl_cnt
            from <someDB>.<someTBL>
            where acctopen_cnt > 0
              and lower(lst_cnf_actvy_typ_cd) = 'acctopen'
              and cast(lst_cnf_actvy_dt_tm as date) between
                  cast(substring('${YYYYMM}' from 1 for 4) || '-' || substring('${YYYYMM}' from 5 for 2) || '-01' as date) and
                  cast((cast(substring('${YYYYMM}' from 1 for 4) || '-' || substring('${YYYYMM}' from 5 for 2) || '-01' as date) + interval '1 month') - interval '1 day' as date)
              and (str_cnt > 0 or phone_cnt > 0 or mail_cnt > 0 or onlnchnl_cnt > 0 or mblbnk_cnt > 0)
            group by 1,2 )
       TDPID('TD_RDBMS_C2T') USERNAME('${c2tUID}') PASSWORD('${c2tPWD}') ${LDAP_IND_AST_C2T}
       TARGET_TABLE ( 'C2T.t_yyyymm_agg' ) LOG_TABLE ('C2T.t_yyyymm_aggLOG')
       MAX_SESSIONS(120));

获取位置的功能

  while (!finishSeeking)
            {
                TimeSpan? currentStreamPosition = Wrapper.GetStreamPosition(streamId);

                if (!currentStreamPosition.HasValue)
                {

                    seekFailed = true;
                    break;
                }

                if (currentStreamPosition >= seekPosition)
                {
                    // reached the position we wanted
                    break;
                }

                if (previousStreamPosition < currentStreamPosition)
                {
                    lastAdvanceTime = DateTime.Now;
                    previousStreamPosition = currentStreamPosition.Value;
                }

                long seekPositionBytes = Wrapper.ConvertOffsetToNumberOfBytes(streamId, seekPosition);

                if (!Wrapper.SeekToPositionInBytes(streamId, seekPositionBytes))
                {

                    seekFailed = true;
                    break;
                }

                if (lastAdvanceTime - DateTime.Now >= SEEK_TIMEOUT)
                {

                    seekFailed = true;
                    break;
                }
            }

以及一些常见的低音API

public static TimeSpan? GetStreamPosition(int streamId)
        {
            long bytesOffset = GetStreamPositionInBytes(streamId);
            var secondsOffset = Bass.BASS_ChannelBytes2Seconds(streamId, bytesOffset);
            if (secondsOffset < 0)
            {
                return null;
            }
            return TimeSpan.FromSeconds(secondsOffset);
        }

我用来寻找内容。首次寻求

Bass.BASS_ChannelSeconds2Bytes(streamId, offset.TotalSeconds);

从不给我更多的时间，而是给我更多的时间，有时它会在9秒内停留在13秒上。因此，我的循环永不中断。

寻找Bass玩家的正确方法是什么？
基地将如何决定下载下一个音频？
我可以直接跳到寻找位置而不是花多长时间吗？循环

低音播放器将内容查找到特定位置
