2、查看视频文件的大小：1554129526 / 1024 / 1024 = 1482.13 MB。如图2

图2

3、查看企鹅号的视频文件分片上传。start_offset：分片的起始位置(从0开始计数)。end_offset：分片的结束位置。status：状态，0：禁用；1：待上传；2：上传中；3：上传中(已失败)；4：已上传。发现状态为3，即上传中(已失败)。已经上传至第 4 个分片，419430400 / 1024 / 1024 = 400 MB。单个分片文件大小为 100 MB。如图3

图3

4、第 5 个分片的起始位置：524288,000，那么第 4 个分片的结束位置：524287999，其值是正确的。查看存储中的原始文件：/2021/10/22/1634900031.6087.46572291.mp4，分片文件的数量总计为 15 个。分片文件不存在问题。如图4

5、使用同样的视频文件再次上传，上传成功，未复现。以下是事务表中的 3 次记录。如图5

图5

start_offset    end_offset    status
629145600       734003199     2
1258291200      1363148799    2
1554129526      1554129526    4   

6、总结：看来只有后续让测试人员再复现一下了。开发人员未复现的。这应该也是偶发问题的。基本上是很难解决了。比如说因为网络抖动、或者说企鹅号的服务器偶发不稳定。
