mpd with multiple periods, multiple keys failing to decrypt

[monk87]

I have a strange case

Mpd with multiple periods with first period being some ad.

https://cf.eu.prd.media.max.com/r/dash.mpd?f.audioCodec=heaac&f.audioTrack=en-US%7Cdescriptive%2Cprogram&f.audioTrack=pl%7Cprogram&f.textTrack=en-US&f.textTrack=pl&f.videoCodec=avc&f.videoDynamicRange=sdr&r.duration=30.000000&r.duration=5751.960000&r.keymod=2&r.main=1&r.manifest=8f26c2a6-0492-4f0e-b57d-3e3226388175%2F0_c34543.mpd&r.manifest=2e8dc8bd-514c-48f9-98da-63fb6e38dab7%2F1_03e3ca.mpd&r.origin=cfc%7Cprd-wbd-emea-vod&x-wbd-tenant=beam&x-wbd-user-home-market=emea

Removed first period, added hostname to every <BaseUrl> part (taken from the segments that came in in network tab) eg. https://cf.eu.prd.media.max.com/2e8dc8bd-514c-48f9-98da-63fb6e38dab7/v/0_6a28f9/v4.mp4

WidevineFetch returned multiple keys but still only audio decoded

command i use

N_m3u8DL-RE btc.mpd --key 01007b3d8622c40b593074d18bcd9648:53d4a6e764e3731ffba0705bc994269e --key 010112575f3d5f1b14ebee8496eca4b7:0670b9339ec092e060bedcae93f85b8b --key 0102af6a082e198682be97fefd0b780a:b4ede66a4e6bb3d333da13beb6e00c36 --key 0105c1a08a823547dfcb6cd9ac24805f:00000000000000000000000000000000 --save-name b -mt -M format=mp4 -sv best -sa lang:pl -ss

Is it too complex thing for N_m3u8DL-RE ?
I also tried dash-mpd-cli but it keeps "Retrying video segment" and downloads only ~45mb file which mp4decrypt fails to decrypt

Your mistake is you're using -sv best with L3 keys and expecting to be able to decrypt 1080p quality. Go for 720p after you removed the ad.

Use that manifest url:

You are limited to 720p on MAX. The key returned for 1080p is 00000...

didn't notice that lol

thanks for clarifying

and is it possible to get a L1 cdm files somehow?

[2nHxWW6GkN1l916N3ayz8HQoi]

and is it possible to get a L1 cdm files somehow?

Public available methods, no.
Private methods found by you, or other knowledgeable users, yes. One way is finding some published papers about specific devices with possible exploits. Then you start from them and come up with your own fancy smart exploit. And you get an L1 somehow. There's no tutorial.

If something is made public, is fixed fast. Just stick to L3.
