Hi, I'm trying to archive this series called "Poppy Cat" and Channel 5 is the only place to watch "Series 2" of the show. However, it expires on the 29th, so I'm worried about if this’ll be lost. How do I download from Channel 5? Tutorials and Links appreciated!
Link: https://www.channel5.com/poppy-cat

Take a look at deccavox's helpful script here: https://forum.videohelp.com/threads/408307-Help-with-getting-keys-for-Channel-5-series...Channel+script
It requires the mpd url, which you get from The Stream Detector extension after playing the video - use "Regular URL".
It also needs the licence url, which you get - in Firefox - by pressing F12, Network tab with "lic" in the filter box, then pressing play on the video. Right click on the link (it should start with cassie) and choose copy as url.

Hello. That's easy even for me. I started looking through these pages a week ago.
So...
1. Download N_m3u8DL-RE for your windows systemCode:https://github.com/nilaoda/N_m3u8DL-RE/releases/tag/v0.1.9-beta
Put in one folder N_m3u8DL-RE.exe, mp4decrypt.exe, ffmpeg.exe (You will find the last two everywhere)
2. Install chrome extension Live cat (for obtaining address of mpd or manifest or whatever). Refresh the page of episode1. Start the video.
Take mpd address from Live cat.
3. Start N_m3u8DL-RE (In the address bar of the folder where is N_m3u8DL-RE type CMD and cmd.exe will pop-up)
Type N_m3u8DL-RE <mpd link>
Choose what video bitrate do u want (it is already selected the best one 832x468 resolution)
Click enter. N_m3u8DL-RE will download encrypted video (mp4) and audio (m4a) Lets rename poppy.mp4 and poppy.m4a
4. Find PSSH. Its in mpdCode:AAAAQnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAACIIARIQ+gpwNgHuRgSrWKrZRDMlAxoIY2hhbm5lbDUqAlNE
You will find PSSH under Console, filter "gen" from generalRequest
5. Find License. In developer tools click Network tab and filter "license" or lic. Refresh page if its not there. Must be something likeCode:https://cassie.channel5.com/api/v2/licences/widevine/,.................
Go toCode:https://cdrm-project.com/
Code:fa0a703601ee4604ab58aad944332503:a6c3d35c78d1d861e01808afcb3f05ed
7. Decrypt video and audio
In folder where your tools are (the one N_m3u8DL-RE and encrypted files) type in address bar CMD again.
cmd.exe will pop-up.
PasteCode:mp4decrypt.exe --key fa0a703601ee4604ab58aad944332503:a6c3d35c78d1d861e01808afcb3f05ed poppy.mp4 poppy_decrypt.mp4 mp4decrypt.exe --key fa0a703601ee4604ab58aad944332503:a6c3d35c78d1d861e01808afcb3f05ed poppy.m4a poppy_decrypt.m4a
8. Mux video and audio with MKV Toolnix
and that was episode 1. Repeat this for all 51 episodesLast edited by lego; 13th Jul 2023 at 02:10.

I have downloaded the first 12 episodes and they are zipped here https://anonfiles.com/Me15P5x6zb/poppycat_zip

I used a channel 5 batch downloader but do not have permission to post as some of the code is not mine. Sorry folks. Cannot imagine downloading 51 episodes by hand!Last edited by A_n_g_e_l_a; 21st Jun 2023 at 06:42.

Hi there,
using the above info I managed to successfully download & decrypt a Channel 5 Video.
So therefore (obviously) I have the PSSH & the Licence URL.
(or had, as they have probably now expired)
How can I do the lookup for the decryption Key(s) without cutting & pasting to https://cdrm-project.com/ ??
A solution using the new Java HttpClient would be most helpful, as I don't do Python. -
I'm still interested in understanding what https://cdrm-project.com/ is doing.
(maybe delegating the request to some google service?)
Nevertheless, here (inline & as attachment) is some (anonymised) Java source to automate the query:
Code:package com.channel5; import java.net.URI; import java.net.http.HttpClient; import java.net.http.HttpRequest; import java.net.http.HttpRequest.BodyPublishers; import java.net.http.HttpResponse.BodyHandlers; import java.nio.charset.StandardCharsets; import java.util.StringJoiner; public class PostAnon { private static final char QUOTE = '"'; public static void main(final String[] args) throws Exception { final var licenceURL = "https://cassie.channel5.com/api/v2/licences/widevine/491/C5458360001"; final var licenceQuery = new StringJoiner(String.valueOf('&')) .add(query(licenceURL + "?expiry", "1714590905")) .add(query( "tag", "12345678901234567890123456789012345678901234567890123456789012345678901234567890")) .add(query( "CMCD", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXXXXXXXXX")) .toString(); final var jsonText = new StringJoiner(String.valueOf(','), String.valueOf('{'), String.valueOf('}')) .add(json("license", licenceQuery)) .add(json("headers", "accept: \\\"*/*\\\"\\ncontent-length: \\\"316\\\"\\nConnection: keep-alive")) .add(json("pssh", "AAAABBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB=")) .add(json("buildInfo", "")) .add(json("proxy", "")) .add(json("cache", true)) .toString(); final var request = HttpRequest.newBuilder() .uri (new URI("https://cdrm-project.com/wv")) .POST (BodyPublishers.ofString(jsonText)) .header("Referer", "https://cdrm-project.com/") .header("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:125.0) Gecko/20100101 Firefox/125.0") .header("Content-type", "application/json") .build(); System.out.println("licenceURL: " + licenceQuery); System.out.println("json Text.: " + jsonText); System.out.println("Request...: " + request); final var response = HttpClient.newBuilder().build().send(request, BodyHandlers.ofByteArray()); final var mpdBytes = response.body(); final var mpd = new String(mpdBytes, StandardCharsets.UTF_8); System.out.println(); System.out.println("Response..: " + response); System.out.println(mpd); } private static String query(final String key, final String value) { return key + '=' + value; } private static String json(final String key, final boolean value) { return quote(key) + ':' + value; } private static String json(final String key, final String value) { return quote(key) + ':' + quote(value); } private static String quote(final String unquoted) { return QUOTE + unquoted + QUOTE; } }

Like most scripts regarding widevine, it's using pywidevine as backend. If you want to automate the entire process for Channel5 without any manual input, you'll need to reverse engineer the API. Python is recommended for obvious reasons, but this can theoretically be done with any language that allows for http requests.

You cannot now use cdrm project for channel 5 lookup. C5 system changed after this thread was created. They now use a weekly changing HMAC and AES key to unlock access to the license server.
If you do Java, as I did once, you can make the translation to Python fairly easily. The benefit is that most code for decryption is written in Python. If you understand data structures then it is only the syntax you'll need to lookup; a web-search, or more latterly an AI instance to chat with, will help with the intricacies of the python code. An AI chat engine will also explain what the code does.
Python is a higher level language and you'll find it easier than Java once you are over the initial shock.
You do not mention having your own Content Decryption Module. Extract one from an Android device - real or virtual if you need. And if that is the case - 'ALL YOU NEED TO KNOW' about decrypting GENERALLY - is is the stickies, at the very top of the forum. Do your homework there before asking more questions - it saves everyone's time.
Working Channel 5 solutions already exist within this forum for those with a CDM of their own - written in Python, of course.Noob Starter Pack. Just download every Widevine mpd! Not kidding!.

Not sure about that. Successfully downloaded...
Andalucia with Michael Portillo
...yesterday using the "How To's" posted earlier in this Thread.
- downloaded *.mpd using URL from "The Stream Detector" Plugin for Firefox
- downloaded Audio & Video using filenames from the *.mpd
- copied PSSH from aforementioned *.mpd
- copied Licence URL from POST using Firefox-F12
- used CDRM Project to extract Decryption Key(s)
- used mp4decrypt with Decryption Key to decrypt Audio & Video
- mux'ed 'em to *.mkv & works fine in the Settop Box. -

Hi there,
just found this thread and was wondering if somebody could help with downloading the 5 episodes of "The Evolution of Black British Music"? It can be found here:
https://www.channel5.com/the-evolution-of-black-british-music/season-1
I would try the provided scripts myself, but unfortunately i cannot access the website because i am not located in the UK. I tried to access via VPN, but still no access.
Would be much appreciated if someone is able to help.
Thank you in advance. -
