linux：m3u8：如何从.m3u8中列出的段手动下载并创建mp4教程
我有一个.m3u8 url,即http://example.com/test.m3u8
我可以通过ffmpeg命令下载它：
ffmpeg -y -loglevel verbose -i "http://example.com/test.m3u8" -c copy -f mpegts test.mp4
但我想手动执行此操作：
我尝试了以下方法：
1)下载m3u8文件：
wget -O test.m3u8 "http://example.com/test.m3u8"
2)然后将每个段下载到一个文件夹中：
aria2c -i test.m3u8
这会下载文件夹中的所有.ts文件.
3)然后我将它们结合起来
cat *.ts > out.ts
4)然后我尝试转换为mp4：
$ffmpeg -i out.ts -c:v libx264 outputfilename.mp4

我最终得到以下上述错误.处理输入时找到无效数据.我也听说这些文件是加密的.所以我不确定如何做到这一点.

解决方法:
关于猫问题.你在考虑BOM吗？
所有.ts文件都以BOM开头,所以如果你捕获它们,它们就会破坏.
根据规范,您可以在媒体播放列表中找到所有必需的加密详细信息.
示例行：
#EXT-X-KEY:METHOD=AES-128,URI="http://example.com/path/to/resource.mp4/crypt.key?id=somekey"
这包含加密算法和密钥的uri.
加密可以是每个列表或每个轨道.在你的情况下,它是每个轨道.

我写了一些关于m3u8 / ts的经历.也许它可以帮助你或给你一些新的想法：https://andreasvolkmann.github.io//m3u8-and-ts-segments/
