我正在制作一个 bash 脚本来使用 crontab 在特定时间下载 m3u8 流。
有时服务器发送的流 url 无效或流停止，因为服务器无法流式传输。
在这两种情况下，playlist.m3u8 和 chunk.m3u8 都是可下载的，但 chunk.m3u8 中的流文件片段不再更新。但是 ffmpeg 一直在下载“无”，因为 chunk.m3u8 文件包含任何新流。
输入指令:
ffmpeg -i 'https://link.to/playlist.m3u8' -c copy -o '~/filename.ts'
关于异常情况:
[generic] playlist: Requesting header
[generic] playlist: Downloading m3u8 information
[download] Destination: ~/filename.ts
