[Bug?] kkr 没有下载全部音频分片

[Skimige]

Env:
KKR / 1.2.9
Node / v14.18.2
npm / 8.3.0

Command:
kkr -d https://www.youtube.com/watch\?v\=LaNzLijZRBo --keep --cooldown 5000 --threads 1 --debug
（cooldown 懒得删了，本来是 --live 下载的，卡在最后两个分片MPD获取失败手动 ^C 了）

准备混流输出文件
kkr决定猜一下合并方法
由于本视频为非低延迟视频 kkr觉得应该使用合并模式2

啊，看到迟了，没有 mpd 文件排查了。你这个最后合并失败好像跟分块数量没关系，你有安装ffmpeg/ffprobe吗，这看起来是合并方式选择错了导致没法合并

[Skimige]

我 PATH 添加了 ffmpeg-4.4-arm64-static，ffmpeg 和 ffprobe 是正常工作的

确实有部分视频目前会有无法合并的问题，正在调查中。请问临时文件还存着吗，可以要一份看看吗

[Skimige]

看来 ls 的时候少看了点东西，思考

文件表明似乎缺少了一个 init 块导致视频信息无法识别。
我在1.2.10版本中增加了 MPD URL 的 debug 输出，下次遇到这种情况麻烦使用 --debug 选项再运行一次，获得 MPD 文件链接后将 MPD 文件一同提交以便排查，十分感谢！
