Key for channel 4 programme

[Willow5]

Hello, while I am waiting for my access to getwvkeys to be approved on Discord, please can someone kindly provide the key for this URL:

https://www.channel4.com/programmes/grease/on-demand/42653-001

Many thanks

Thank you so much ! I am trying to use mp4decrypt with the key but it doesn't appear to be working. Do I need to be using something else for the mp4 and m4a files like a Key ID ?

[A_n_g_e_l_a]

The space is an artifact from somewhere and shouldn't be there. Same key for both streams.

just checked my original post and tried to edit out the space - it wasn't there. So this crappy outdated vBulletin that the site owner uses inserted it for free!

[Willow5]

Thank you very much. I tried without the space but cannot get ffmpeg to work at the end, it keeps saying:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0000016e7996d080] Incorrect number of samples in encryption info
gv_dec.mp4: Invalid data found when processing input
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000016e7c8df0c0] Incorrect number of samples in encryption info
ga_dec.mp4: Invalid data found when processing input

Is this the right sequence of events I am using?

mp4decrypt --key 587ee28c0a27a7da3cfdb43604013bcc:d81b6445425c0e00e 574adf13cece4e8 gv.mp4 gv_dec.mp4
mp4decrypt --key 587ee28c0a27a7da3cfdb43604013bcc:d81b6445425c0e00e 574adf13cece4e8 ga.m4a ga_dec.mp4
ffmpeg -i gv_dec.mp4 -i ga_dec.mp4 -c copy final.mp4

The space is also present on my post and I cannot also seem to edit it out!

[A_n_g_e_l_a]

can you play the unencrypted streams individually? vlc gv_dec.mp4 for instance?

for ffmpeg I usually ffmpeg -i audio.m4a -i video.mp4 -acodec copy -vcodec copy output.mp4 But I can see much difference with general copy command.

I'm just wondering, my stream urls are from the channel4 app and maybe a different key from desktop urls?? But the VLC check will tell you.

I've just download it and it plays for me screen height is 576 not too good if you were expecting 1080.

try this

587ee28c0a27a7da3cfdb43604013bcc:d81b6445425c0e00e574adf13cece4e8

when you set a number greater than 50 characters, the forum automatically add a space

to work around this you must enter the value in the code tag

[Willow5]

I tried playing the gv_dec.mp4 file on VLC and it shows the length of the file but nothing is displayed on the screen. I was expecting the video only to be displayed without the audio but I get nothing. Is there any way you can get the desktop key please as they might be different ?

[Willow5]

interesting thanks for checking. Have I done this correctly? I first downloaded the mpd file as follows:

ytdlp.exe --allow-u --downloader aria2c -f bv,ba "mpd link"

then I used the 2 mp4decrypt commands with your key. Is there something I have done incorrectly ?

OK my mistake then. Sorry. But we now know chan4 app keys and desktop keys are different.
@lomero Thanks for the [code] tip

[Willow5]

Thank you that worked ! Only problem now is that I appear to have downloaded the audio description track instead of the non-audio description track. How can I download the non-audio description track please from the mpd file ?

[lomero]

yt-dlp -F link ---- and you have a full list available
yt-dlp -f xxx link --- use this when you have choice your download track (replace xx with right value)

here your full list


[Attachment 66668 - Click to enlarge]

so, run like example yt-dlp --allow-u -f audio_eng=128000 "https://mpd" to download audio only eng format

[[ss]vegeta]

Well, there are 2 audio tracks, dunno which one's which so you can download them like this

ytdlp.exe --allow-u -f audio=128000 "mpd"

ytdlp.exe --allow-u -f audio_eng=128000 "mpd"

ytdlp.exe --allow-u -f audio=128000 "mpd"

ytdlp.exe --allow-u -f audio_eng=128000 "mpd"

I use worst audio -- yt-dlp --allow-u -f wa ...etc etc thats the first one in the list. Yt-dlp selects the best ie. the lowest list order for the download unless overridden.

[Willow5]

I tried that option but it returns this:

[generic] stream.mpd?c3: Requesting header
WARNING: [generic] Falling back on generic information extractor.
[generic] stream.mpd?c3: Downloading webpage
[generic] stream.mpd?c3: Extracting information
ERROR: [generic] stream.mpd?c3: This video is DRM protected

[[ss]vegeta]

"This video is DRM protected" is only returned when you don't use --allow-u

Hi, I'm a newbie, I don't know anything about coding.
Can you make a video showing me how to get channel4.com key?
I watched a video on how to get your Player.pl key. And I got the key successfully.
But that doesn't apply to channel4.com. Please help me.
I can watch your videos and follow along.

Yeah, that would be you doing the equal part

I think he was being sarcastic lol
I have a video showing how to get channel4 keys made by someone (maybe even vegeta) that I downloaded some time ago, but I haven't tried it yet since I don't have a VPN:
https://userscloud.com/krbtlgquywpd
good luck

[[ss]vegeta]

Yeah, that's not me. I'm not doing webms. I'm doing glorious master race mp4 or mkv.
I remember that video too, maybe it was pkp? Not sure either. We already forgot that hero... he deserves better.

I want to say thank you very much. <3
I watched your video tutorial to get the key player.pl.
I followed the video instructions and got the key.

that script is old and doesnt work anymore. you need to get the latest one from getwvkeys discord

[ampersand]

if you don't get the one on discord, you can try the method from this thread (Diazole's downloader):
https://forum.videohelp.com/threads/407144-Help-with-Channel-4-Key-to-this-programme-a...-method-please

I don't have a VPN right now so I don't know if it works
