My5.tv DRM - any way around it?

[spherular]

I had a request from my in-laws to get a file that I'm almost certain can only be acquired from My5.tv - https://www.my5.tv/all-creatures-great-and-small/season-2/episode-1

I managed to acquire a few file addresses

https://hwdash.channel5.com/cenc/C5344020001/C5344020001A/20210917131714/C5344020001A_...ASH_1500_v.mp4

yt-dlp pulled the files I needed and I even got mp4 and m4a files using another app. 500mb video and 32mb audio so the correct size. However the DRM is stopping me doing anything with these files.

I also tried Camtasia and the screen is blank as expected - I even tried Bluestacks/MEMU/NOX and installed the my5.tv app and couldn't get the videos to play.

Hoping someone can give me that last piece of info on how to unencrypt these files - I'm assuming widevine L3?!

Thanks in advance

Got the keys

KID: fd6914e7910440f8884864004f5e6f51
HEX: caef3ee0679cc302147870d6dfd976bb

KID: 92837c4756ab1e322d4707c34dd35028
HEX: caef3ee0679cc302147870d6dfd976bb

and successfully decrpyted the files. Merge seemed to go ok, but no sound.

So close!

I have no idea why you have no sound, your keys are correct. You messed up something.
Here's the audio, try merging the video with this one.

Must be a codec thing as I have no sound on that file also - weird.

I'll try the merge and see if Plex can figure it out.

I tried both and both commands ran but there was no audio - yours did work so thank you!

Sorry to comment on an old thread but im experiencing a similar issue with this video:
https://www.channel5.com/show/warship-life-at-sea/season-3/episode-2

I've got both files and my keys are:
5abbbebdc72e4d279203f9d47a6839ac:48128f6355e0db003 38a8cddeda42078
204bbfc2d5c82b8e8810e9abfe95747b:48128f6355e0db003 38a8cddeda42078

The video decrypts fine but the audio doesnt work. Any help is greatly appreciated.
