entityMap|blocks|key|4jfsd|text|为了解密加密的视频流，你需要加密密钥。这个密钥是|type|unstyled|depth|inlineStyleRanges|entityRanges|data|cuecb|注释|3ock5|流的一部分。应该单独获取。|c62vi|EXT-X-FAXS-CM报头包含DRM元数据而不是密钥。|kve2|这是Adobe+Media+Server开发人员指南的摘录:+Adobe+Access+Server+protected+variant播放列表还需要包括#EXT-X-FAXS-CM标记。可变播放列表中的#EXT-X-FAXS-CM标签的值是引用客户端的单个streams.At之一的DRM元数据的相对URI，可变播放列表中的#EXT-X-FAXS-CM标签将用于创建DRM会话。相同的DRM会话将用于可变播放列表内的所有加密的M3U8文件。|dguci|完整的指南可以在这里找到：|dospp|http://help.adobe.com/en|3l75v|_|7org6|US/adobemediaserver/devguide/WS5262178513756206-4b6aabd1378392bb59-7fe8.html|30g6t|还提到了faxs://faxs.adobe.com+URI用于本地密钥服务。因此从设备本地获得密钥。^0|0|0|0|0|0|0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|U|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|V|9|@]|A|@]|B|$]]|$2|E|4|F|6|7|8|W|9|@]|A|@]|B|$]]|$2|G|4|H|6|7|8|X|9|@]|A|@]|B|$]]|$2|I|4|J|6|7|8|Y|9|@]|A|@]|B|$]]|$2|K|4|L|6|7|8|Z|9|@]|A|@]|B|$]]|$2|M|4|N|6|7|8|10|9|@]|A|@]|B|$]]|$2|O|4|P|6|7|8|11|9|@]|A|@]|B|$]]|$2|Q|4|R|6|7|8|12|9|@]|A|@]|B|$]]|$2|S|4|T|6|7|8|13|9|@]|A|@]|B|$]]]]

In order to decrypt encrypted video stream you need encryption key.
This key is not part of the stream. It should be obtained separately.

EXT-X-FAXS-CM header contains DRM meta-data and not the key.

This is excert from Adobe Media Server developer guide:
The Adobe Access Server protected variant playlist also needs to include the #EXT-X-FAXS-CM tag. The value of #EXT-X-FAXS-CM tag in variant playlist is the relative URI referring to the DRM metadata of one of the individual streams.At the client, the #EXT-X-FAXS-CM tag in variant playlist will be used to create the DRM session. The same DRM session will be used for all encrypted M3U8 files inside the variant playlist.

Full guide can be found here:
<a href="http://help.adobe.com/en_US/adobemediaserver/devguide/WS5262178513756206-4b6aabd1378392bb59-7fe8.html" rel="noreferrer">http://help.adobe.com/en_US/adobemediaserver/devguide/WS5262178513756206-4b6aabd1378392bb59-7fe8.html</a>

There is also mention that faxs://faxs.adobe.com URI is for local key serving.
So key obtained locally from a device.

entityMap|blocks|key|fvp6q|text|这可能有点麻烦，但是给定一个.m3u8文件的URL，它将下载并解密组成流的文件：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|6ca5r|#!/usr/bin/env+bash

This might be a bit of a hack, but given a URL to an .m3u8 file, it will download and decrypt the files that make up the stream:

<pre><code>#!/usr/bin/env bash
curl "$1" -s | awk 'BEGIN {c=0} $0 ~ "EXT-X-KEY" {urlpos=index($0,"URI=")+5; ivpos=index($0,"IV="); keyurl=substr($0, urlpos, ivpos-urlpos-2); iv=substr($0, ivpos+5); print "key=`curl -s '\''"keyurl"'\'' | hexdump -C | head -1 | sed \"s/00000000//;s/|.*//;s/ //g\"`"; print "iv="iv} $0 !~ "-KEY" &amp;&amp; $0 ~ "http" {printf("curl -s '\''"$0"'\'' | openssl aes-128-cbc -K $key -iv $iv -d &gt;seg%05i.ts\n", c++)}' | bash
</code></pre>

This script generates a second script that extracts keys and initialization vectors and uses them to decrypt while downloading. It needs curl, awk, hexdump, sed, and openssl to run. It'll probably choke on an unencrypted stream, or on a stream that uses something other than AES-128 (is any other encryption supported?).

You'll get a bunch of files: seg00000.ts, seg00001.ts, etc. Use tsMuxeR (<a href="https://www.videohelp.com/software/tsMuxeR" rel="noreferrer">https://www.videohelp.com/software/tsMuxeR</a>) to merge these into a single file (simple concatenation didn't work for me...it's what I tried first):

<pre><code>(echo "MUXOPT --no-pcr-on-video-pid --new-audio-pes --vbr --vbv-len=500"; (echo -n "V_MPEG4/ISO/AVC, "; for i in seg*.ts; do echo -n "\"$i\"+"; done; echo ", fps=30, insertSEI, contSPS, track=258") | sed "s/+,/,/"; (echo -n "A_AAC, "; for i in seg*.ts; do echo -n "\"$i\"+"; done; echo ", track=257") | sed "s/+,/,/") &gt;video.meta
tsMuxeR video.meta video.ts
</code></pre>

(Track IDs and framerate may need adjustment...get the values to use by passing one of the downloaded files to tsMuxeR.)

Then use ffmpeg to remux to something a bit more widely understood:

<pre><code>ffmpeg -i video.ts -vcodec copy -acodec copy video.m4v
</code></pre>

While some of the bash scripts in the existing answers get you part (or even all) of the way, depending which site you're trying to download from, you might hit other obstacles (different auth method, custom license server mount, etc.)

I've found <a href="https://streamlink.github.io" rel="nofollow noreferrer">streamlink</a> to be the most robust solution for this, which also lets you stream directly (rather than download), if that's what you're after, and it has all the site-specific work already done for you for a long list of sites (see <a href="https://streamlink.github.io/plugin_matrix.html" rel="nofollow noreferrer">plugins section</a>, but keep in mind it's under active development and the latest release was in June, so for some of the newer ones you'll have to <code>git clone</code> and install from source).

I trying to decrypt AES-128 encrypted m3u8 video files such as this one :

the m3u8 file :

I've tried with openssl : 

<pre><code>openssl aes-128-cbc -d -kfile key.txt -iv 99b74007b6254e4bd1c6e03631cad15b -nosalt -in video_enc.ts -out video_dec.ts

key.txt contains the very long key
