Need help downloading DRM encrypted MPD stream, please PM me. Thanks !

[shock]

Need help downloading DRM encrypted MPD stream, please PM me for more details. I was able to download the encrypted max stream size - 1080p and AAC audio, using yt-dlp.

Here is the output from mp4dump:

D:\>mp4dump 1.mp4 | findstr /I /L "kid key_id"
default_KID = [40 04 3a 93 1d b8 e0 9a 3c 3a a8 48 48 ac 18 30]
kid 0 = [40 04 3a 93 1d b8 e0 9a 3c 3a a8 48 48 ac 18 30]

D:\>mp4dump init.mp4 | findstr /I /L "kid key_id"
default_KID = [40 04 3a 93 1d b8 e0 9a 3c 3a a8 48 48 ac 18 30]
kid 0 = [40 04 3a 93 1d b8 e0 9a 3c 3a a8 48 48 ac 18 30]

D:\>mp4dump 1.mpa | findstr /I /L "kid key_id"
ERROR: cannot open input (-4)

D:\>mp4dump 1.m4a | findstr /I /L "kid key_id"
default_KID = [40 04 3a 93 1d b8 e0 9a 3c 3a a8 48 48 ac 18 30]
kid 0 = [40 04 3a 93 1d b8 e0 9a 3c 3a a8 48 48 ac 18 30]

MPD file contains the following:

<ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" />

I tried to generate PSSH to get the decryption keys, but with little to no success. Any help would be much appreciated. Thanks !

upload your mpd

Here you go

[pkp]

Try this PSSH

Try this PSSH

Thanks, but i just get an error when i try to obtain the keys - "Error 404: {}"

It seems the License URL (https://nbaapi.neulion.com/api_nba/v1/publishpoint) is being protected with some cookies, such as "drmtoken=true", "deviceid=web-" etc. And the PSSH doesn't look like what people in this forum have described in the past:

And i think both Widewine and PlayReady are used to encrypt the stream...

The DRM token is from the Lic URL? How wer you able to calculate the right PSSH, this is the hardest part for me, other than parsing the right headers to authenticate

https://base64.guru/converter/encode/hex >>>> hex to base64

of course if your coding a script you can automate the process with mp4dump

yes u should use the same headers as is used by your request

just depends on how your planning on getting keys

of course if your coding a script you can automate the process with mp4dump

yes u should use the same headers as is used by your request

just depends on how your planning on getting keys

Thanks for your help, i am not a coder, but i need to figure a way out to automate at least part of the process.

yeh i fully automated it for live and vod last year
