看样子是流有问题 建议使用二进制合并

把1800的限制去掉就没有问题了

你的第一个m3u8链接之所以会遇到1800的限制是因为这个m3u8中没有#EXT-X-DISCONTINUITY标记，程序会认为这一整个视频都是参数相同的TS片段，会全部使用ffmpeg合并，但是程序调用的参数传入有长度限制，故每N个小分片先合并为T0000.ts、T0001.ts、T0002.ts……之类的大分片，再使用ffmpeg来concat。这样的行为通常应对点播平台是没有问题的，但你这个应该是直播回放，存在服务器切片或主播网络波动等因素导致的某些TS包中不含有正确PTS信息的问题，让ffmpeg在封装mp4时无法构造moov box，自然无法合并。

第二个m3u8链接的内容有#EXT-X-DISCONTINUITY标记，它将m3u8分为了两个不同的部分，程序会认为这两个部分的视频参数可能不完全一样，则尝试以下动作：将各个分片二进制合并为Part0.ts、Part1.ts，然后使用ffmpeg对这两个大分片进行concat（这种情况常见于flv分片切片m3u8，如早期的搜狐视频）。

所以直播回放我建议直接使用二进制把他们统一合并为TS观看，这样最为万能。

PS：若只想要其中的某些片段，可以考虑使用--downloadRange选项，或使用GUI指定：
