Downloading encrypted mpd video files

[umar_0x01]

Hi everyone,

I usually download m3u8 files from sites and they work fine with both youtube-dl and FFmpeg. Came across an MPD file today while trying to download some courses from a site and thought of downloading it. All the files are in the same format.

The MPD download file shows errors with FFmpeg but downloads while youtube-dl directly gives up. I've added both what I've tried, what was the output, and error logs below. Would appreciate any help!

MPD file URL (won't work without fastly_token parameter):

https://manifest.prod.boltdns.net/manifest/v1/dash/live-baseurl/bccenc/6015698128001/e...M3ODFmMw%3D%3D

Commands tried:

ffmpeg -i "https://manifest.prod.boltdns.net/manifest/v1/dash/live-baseurl/bccenc/6015698128001/ed435ad2-5470-4503-ae94-a44182720ba7/6s/manifest.mpd?fastly_token=NjAzNjcwMGRfYWRmZjU1NzM4MDk5YWVkZjA4MzUxNzg5NWQ5NzdkNGY0NzBmNTI4YTk5YTk0ZTY5MTRiM2ZjYjA2N2M3ODFmMw%3D%3D" -c copy test3.mp4

Output:

Thanks for your reply. Installed it and it isn't working as well. Also one thing, the URL expired yesterday, here's the new URL: https://manifest.prod.boltdns.net/manifest/v1/dash/live-baseurl/bccenc/6015698128001/d...g0N2E1NQ%3D%3D

from https://github.com/yt-dlp/yt-dlp
try it like this
you have to add --allow-unplayable-formats option

yt-dlp --allow-unplayable-formats "https://bitmovin-a.akamaihd.net/content/art-of-motion_drm/mpds/11331.mpd"

or with aria2c

yt-dlp --external-downloader aria2c --allow-unplayable-formats "https://bitmovin-a.akamaihd.net/content/art-of-motion_drm/mpds/11331.mpd"

it also supports sample-aes segments downloading

OMG IT WORKED FOR ME, although it only downloaded the video track. To download the audio I had to use the -F option and select the format I wanted. For example:

yt-dlp -F --allow-unplayable-formats ".mpd link"

yt-dlp -f FormatID --allow-unplayable-formats ".mpd link" -o audio.mp4

And then I just had to decrypt them. Thank you very much!

[umar_0x01]

Thanks but the issue is that I was able to download the mpd file but it's encrypted. I even have the license API call to the server but the data is in binary and the decryption requires a key. Can't figure it out.

Install this chrome extension (I got that link from here), go to video url, open dev tools and click on console tab to get the key.

Then install Bento4 and decrypt the file using:

mp4decrypt --key 1:FoundKey --show-progress EncryptedInput.mp4 DecryptedOutput.mp4

The same happens with audio. After first 11 seconds, there's only silence.

I see, can you please share the extension again? The anonfiles one didn't work so I instead cloned from github and ran it.

Ran actually two extensions but console was empty (on linux, is that the issue? I remember the README mentioning dlls)

Please host the extension somewhere else and share link, can't be downloaded from there.

I honestly don't know, always used it on Chrome for Windows and never had any issues.

Please host the extension somewhere else and share link, can't be downloaded from there.

Just remember unzip the extension and load it as unpacked https://mega.nz/file/DypwzJiQ#8FbRF-bDoA303ch7N416Wl0a8Roi5__1Bd5tG6GB57g

Hello thanks i see the problem i think ffmpeg merged the audio and video file into 1 file thats not gonna work u wont be able to play that video so it is a bad output let ffmpeg idownload video and audio seperate without merging them after that u can decrypt it without problems

[lfer94]

If video and audio are merged, try with:

mp4decrypt --key 1:86a03517bd786028da87e5cff74479b7 --key 2:86a03517bd786028da87e5cff74479b7 E01.mp4 E01decrypted.mp4

Install an older version of Chrome. First result of google search for "old chrome version" will lead you to a site with many installers, install around version 81, from early 2020 or something.
Then load the extension again.
