Download encrypted video via DRM protected MPD manifest

[Beta2k]

I want to download the video based on the MPD file at https://prod-kami.wuaki.tv/v1/delivery/dash/avod/cdc82654-5687-44b0-bcd2-417b289064fb.mpd
The content of the MPD (in case the link only works temporarily) can be seen here: https://pastebin.com/R0LxJyMr
The video can be seen here (account registration is possible and free in most countries): https://rakuten.tv/at/streams/movie/break-point-a-davis-cup-story

I would not mind having an encrypted video downloaded, because I think I can decrypt it with the key. So getting the encrypted video would be fine for me.

I tried with youtube-dl, ffmpeg (version 4.3.1) and streamlink (version 1.7.0), but neither worked. Streamlink says that the MPD "is protected by DRM".

Any way to get the video? Thanks for your help.

Encrypted with Microsoft PlayReady. This DRM is known to be a tough one, afaik.. if you truly have the decryption key, I'd love to know how you acquired it (in PM). Maybe I could help you further in private. It's against forum rules to discuss any further...

Edit: scratch that... the site is unavailable in my country. Can't help you any further. Good luck.

I just managed to download the video and decrypt it successfully.

1) Download with youtube-dl by fetching the correct URL manually via google chrome dev console which is something like (not sure if this url only works temporarily): https://prod-avod-pmd.centurylink.cdn.rakuten.tv/5/9/7/597d325e2bcaf175683d4d857c12f26...2e4778c69e52b7

2) then get the key with a chrome extension that I will not link here, but it's still on GitHub. probably not for much longer.

3) decrypt with mp4decrypt.

4) mux with separately downloaded and decrypted audio stream

5) enjoy

Hi mate, can you pls write how to properly decrypt it with mp4decrypt?

[lomero]

search bento mp4decrypt.
and read other post on this forum. is full to this argument.

Hi all.
I sucessfully downloaded (drm) video from a film site. I found the mpd, downladed the mp4 with ffmpeg. I have the keys too but after decrypting with bento4, the video is still green, blue etc... any idea what's wrong?

A number of things can be wrong.
What is the source?
Sometimes video might feel encrypted, but it's "not" encrypted because when you downloaded with some program, the program didn't include the init file.
Maybe the keys are wrong.
Maybe the track ID is wrong or anything else with your mp4decrypt code.
Have you successfully decrypted before?
You can provide more info in private message if you want, like link user/pass for login etc.

The video is from a hungarian movie site (filmio.hu), needs to pay monthly and you can watch restored old movies in great quality. (4 dollars only)
In the other thread there was a test encrypted video with code to decrypt. I did it succesfully. Maybe the decrypt command wrong with this one? Pm to you.

FFmpeg corrupts DRM-protected content when downloading. You must use yt-dlp or n_m3u8dl to download properly.

[rajhlinux]

I also have decryptions keys.

But how can I download the video for DRM Widevine L3 protected content? It seems the video is cut into many pieces which are encrypted, how can I download all of them in the proper synchronized order?

So that I can decrypt all the videos after downloaded then stitch them together using ffmpeg or some video editor.

Website is Udemy.com

Thanks

Write a python script to do it

You basically need to download the init.mp4 file first, then download all the segments in their order, and concatenate each onto the init file

eg

init.mp4 + segment0.mp4 + segment1.mp4... all the way to the last segment, you just join them all together

If you don't know how to code python or atleast write a simple bash script on Linux, you can do this manually but it will take you a long time...

wget -O ./myfolder/video_encrypted.mp4 http://url.com/init.mp4
wget -O ./myfolder/segment0.mp4 http://url.com/segment0.mp4
cat ./myfolder/segment0.mp4 >> ./myfolder/video_encrypted.mp4
wget -O ./myfolder/segment1.mp4 http://url.com/segment1.mp4
cat ./myfolder/segment1.mp4 >> ./myfolder/video_encrypted.mp4

and you keep on going until you get to the last segment for the video stream, then repeat again for the audio stream. Run mp4decrypt on the resulting concatenated mp4 files once all segments are downloaded, then run mkvmerge on the decrypted video and audio, eg "mkvmerge -o myvideo.mkv video_decrypted.mp4 audio_decrypted.mp4"

The above is very easy to put into a basic bash script, just pull the segment url's etc... from the manifest. If you know python then have it download the manifest along with all the segments using python requests.

From the Ministry of Resurected Threads.
The Ministry consider old threads to be of little use to anyone as the OP may have left; be deceased; or otherwise indisposed. However, this poster has been authorized by the Ministry to post the following:-

yt-dlp can dowload multi-parts but may trip over itself trying to save the same file-name over the previous part. Hence an output formatter is required in the yt-dlp call.

Recently one UK TV provider has added DRM videos in multipart - many of the parts are adverts. Each time you get a manifest, the true program parts have different sequence numbers. There also may be a different number of parts too! Offending manifest urls start with 'ssai.manifest...' my workaround notes for this are below and may be of use to @rajhlinux

GENERAL SEQUENCE FOR SSAI MPD
Download all video and audio to a chosen height/audio quality check availability with yt-dlp -F <mpd url>
yt-dlp  --allow-u -f all[height=1080]  -o  "TestVid.%(format_id)s.%(ext)s" --downloader aria2c <mpd url>
yt-dlp  --allow-u -f all[vcodec=none][abr=127]  -o  "TestAud.%(format_id)s.%(ext)s" --downloader aria2c <mpd url>
This will download adverts as well as part video; there is no way of knowing which part is which until after download
look in list of part-streams for largest file size. if something was downloaded in 2/3 seconds ignore

DECRYPT PART STREAMS obtain a key for decryption by your normal method
mp4decrypt --key xxx:xxx TestVid.fc73af88-2eec-4bf7-a255-3412685795bb-1.mp4 videoP1.mp4  # repeat for n parts
mp4decrypt --key xxx:xxx TestAud.default_audio128_5_en_main-1.m4a  audioP1.m4a           # repeat for n parts

COMBINE THE PART AUDIO AND VIDEO STREAMS
ffmpeg -i videoP1.mp4 -i audioP1.m4a -v:c -a:c Part1.mp4 #  repeat for n parts

CREATE LIST OF PART FILES and save as mylist.txt
file 'part2.mp4'
file 'part3.mp4'
file 'part4.mp4'
file 'part5.mp4'
file 'part6.mp4'

Finally CONCATENATE ALL THE PARTS INTO ONE VIDEO
ffmpeg -f concat  -i mylist.txt -c copy FullVideoName_E01.mp4

doing it in this sequence avoids video timing problems; adding a part-video and a part-audio after decryption stops the final video showing its running time 3  times larger with null gaps.

Is it possible to decrypt playready DRM? If yes may I ask you how?

[frzr215]

possible to restream to ffmpeg on the fly instead of downloading ?

[daymeister]

[ss]vegeta i realy need your help for drm , would you help me ?

Is downloading protected videos still possible? If so can someone guide me in the right direction? I have some videos from a tutorial on Udemy that I purchase and I want to be able to view them off
line. Coding tutorials are hard to see on a mobile phone, that's why I want to view them on PC. I already looked into yt-dl and ffmpeg but don't know what path to go down on what I want to accomplish.

You can also watch them online and if you want to save them for offline purpose then this could be helpful. https://github.com/Puyodead1/udemy-downloader

I searched a lot and did not find anything clear about how to download or decrypt the video, I found some replies for you and I wanted to write to you if you could help me .

Thank you .
