此 HLS 视频流已加密。 AES-128 不是 DRM，因此可以使用密钥对其进行解密。
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
-ss 32: 跳到 32s.-t 17: 设置时长为17秒-c copy：执行流复制（质量无损失）。
个别细分
这需要您自己解密片段。
当您下载解密密钥 59612.key 时，您会看到很多乱码：Aæª~ý÷øŽ©ýÛO®ø.
您必须将其转换为十六进制二进制表示形式。这可以通过 hexdump...
来完成
curl -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612.key | hexdump -e '16/1 "%02x"
41e61c18aa7efdf7f88ea9fddb4faef8
...或者使用我最喜欢的工具之一，xidel:
xidel -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612.key -e 'x:string-to-hexBinary($raw)'
41E61C18AA7EFDF7F88EA9FDDB4FAEF8
接下来你可以用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 0000000000000000000000000000003C: 60（十进制）= 3C（十六进制）。
...或 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

此 HLS 视频流已加密。 AES-128 不是 DRM，因此可以使用密钥对其进行解密。
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
-ss 32: 跳到 32s.-t 17: 设置时长为17秒-c copy：执行流复制（质量无损失）。
个别细分
这需要您自己解密片段。
当您下载解密密钥 59612.key 时，您会看到很多乱码：Aæª~ý÷øŽ©ýÛO®ø.
您必须将其转换为十六进制二进制表示形式。这可以通过 hexdump...
curl -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612.key | hexdump -e '16/1 "%02x"
41e61c18aa7efdf7f88ea9fddb4faef8
...或者使用我最喜欢的工具之一，xidel:
xidel -s https://cloudflare2.jove.com/CDNSource/hls/59612/59612.key -e 'x:string-to-hexBinary($raw)'
41E61C18AA7EFDF7F88EA9FDDB4FAEF8
接下来你可以用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 0000000000000000000000000000003C:60（十进制）=3C（十六进制）。
...或 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
