linux：m3u8：如何从.m3u8中列出的段手动下载并创建mp4

时间：2018-06-01 10:18:35

标签： linux bash ffmpeg m3u8 aria2

我有一个.m3u8网址，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

但我正在尝试手动执行此操作：

我尝试了以下内容：

1）下载m3u8文件：

wget -O test.m3u8 "http://example.com/test.m3u8"

2）然后将每个片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

out.ts: Invalid data found when processing input

我最终得到以下错误。 Invalid data found when processing input。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。

下面是一个示例.m3u8文件：

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。
