以上面的URL为例，它将使用这样的.ts文件（通过Google Chrome devtools）

但我不知道如何使.ts文件在本地可见

我试过这样的东西。但我总是犯错误

这个HLS视频流是加密的。AES-128不是DRM，因此在密钥存在的情况下可以对其进行解密

HLS视频流 简单的方法是使用FFmpeg（它会自动解密）打开HLS视频流并剪切所需的片段：

ffmpeg -ss 32 -i https://cloudflare2.jove.com/CDNSource/hls/59612/59612_.m3u8 -t 17 -c copy output.mp4

  • -ss32
    ：跳到32s
  • -t17
    ：将持续时间设置为17s
  • -c copy
    ：执行流复制（无质量损失）
单个段 这需要您自己解密该段

当您下载解密密钥
59612.key
时，您会看到很多乱七八糟的信息：
aæª~ aý÷OŽOø

您必须将其转换为十六进制二进制表示形式。这可以通过
hextump
完成


curl -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612.key | hexdump -e '16/1 "%02x"
41e61c18aa7efdf7f88ea9fddb4faef8


…或使用我最喜欢的工具之一：

接下来，您可以使用
ffmpeg
解密第60段（例如）：


ffmpeg \
-key 41E61C18AA7EFDF7F88EA9FDDB4FAEF8 \
-iv 0000000000000000000000000000003C \
-i crypto:https://cloudflare2.jove.com/CDNSource/hls/59612/59612_60.ts \
-c copy \
output.mp4



    

  • -iv 0000000000000000000000003c
    ：
    60
    （十进制）=
    3C
    （十六进制）
    • 


…或使用openssl
：

openssl \
aes-128-cbc \
-in <(curl -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612_60.ts) \
-out 59612_60-decrypted.ts \
-d -iv 60 -K 41E61C18AA7EFDF7F88EA9FDDB4FAEF8

openssl\
aes-128-cbc\

-在这种情况下，命令应该起作用。很可能这些文件有数字版权管理。如何解码？因为视频可以在浏览器中看到，所以必须有一种方法来解码它？首先检查它是否是DRMed。然后获取密钥。然后解密。然后解码。你能显示要使用的确切命令吗？不。那不太可能，因为缺少信息。这个分类看起来像HLS片段。意思是有一个清单。没有舱单我什么也做不了。

openssl \
aes-128-cbc \
-in <(curl -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612_60.ts) \
-out 59612_60-decrypted.ts \
-d -iv 60 -K 41E61C18AA7EFDF7F88EA9FDDB4FAEF8
