各位大佬，谁能流畅播放这个 m3u8，试过好几只鸡 ffmpeg 录制不超过 3 分钟中途 404 退出，估计速度跟不上，请提供思路。

$ ffmpeg -t 3600 -i 'http://fash1043.cloudycdn.services/slive/_definst_/ftv_midnite_secrets_adaptive.smil/chunklist_b4700000_t64MTA4MHA=.m3u8' -c:v copy -c:a copy -bsf:a aac_adtstoasc ./test8.mp4

本地也可以录，fash1043.cloudycdn.services 解析出 152.195.33.48 这个美国堪萨斯 ip，3000-4000 bitrate 挺高了，难道要开台美国 G 口鸡试？

本地 dns 污染，hosts 加一行

观察到 fps 逐渐降到 30 左右，然后卡住 404，退出

老哥请教下 ffmpeg 如何将音频加到一个视频里面去 并且自定义导出视频的路径 例如 mp3 +mp4 输出一个带有 mp3 音乐的 mp4 视频

[bog]

播了 6min，没什么问题呀

[expy]

streamlink "hls://fash1043.cloudycdn.services/slive/_definst_/ftv_midnite_secrets_adaptive.smil/chunklist_b4700000_t64MTA4MHA=.m3u8" best -o v2ex.ts

[twoconk]

@zhuzhibin 你这个需要用到音视频的合并，整理了常用的命令（ https://it3q.com/article/59 ），可以参考

[myCupOfTea]

要不就先用 python 爬了,然后再 ffmpeg -i xxx.m3u8 -c copy out.mkv 合并

[shitbreak]

@myCupOfTea 太高级了。。。

[shitbreak]

@bog 我这广州移动宽带没办法，考虑在服务器完成再拖回来

[shitbreak]

@expy 请解释一下，大佬

[expy]

@shitbreak https://streamlink.github.io/
我试了一下能下载，就是中间有丢帧。

[shitbreak]

@expy 我估计它是一堆.ts 轮播，速度不够就丢帧

[myCupOfTea]

你这好像是直播流吧,我用我自己写的下片代码爬了下,好像每次访问下载的三个 ts 文件都不一样

@myCupOfTea https://github.com/MyCupOfTeaOo/flv-download 换个地址

[wnpllrzodiac]

直接下载切片吧。或者换个 ua 。最基本的就是把 ff 的请求给限速，不让你这样人爽😄
