help with free livestream on tvnow.de

[Killer3737]

Hi,

Looking for suggestions on how to capture this live stream on TVnow.de

It is free and non-geoblocked, at least I can watch it in the UK.

https://www.tvnow.de/live-tv/events/utopia-stage-freitag-965762

I haven't had to download streams for a while, seems things have changed a lot since I did with DRM stuff. I can get the MPD file and I see it's protected with Widevine but after that I'm struggling. I think I need to get a PSSH key, but not sure how?

I think it's streamed on Youtube as well but this will be better quality.

Thanks

search "mpd" ; from preview tab you can see pssh (filter with "pssh")

AAAANHBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABQIARIQQGDfaOySw9HrFQYlhdFrLg==

then your key

the PSSH is in the MPD file
you then need a working CDM and make a request for that PSSH with the headers (token is in the headers)
payload itself is only raw request, token gets passed via headers

you can also directly use lomero's key to decrypt the downloaded files
what I described above would be if you wanted to obtain that key yourself

Much appreciated. So now I just download with N_m3u8DL-RE.exe and decrpt afterwards with mp4decrpt, have I got that right?

Yes, you can decrypt the video and audio files with mp4decrypt.
Then merge the two files together (i.e. using mkvmerge or ffmpeg) to get a file with both video and audio combined.

Thanks, just did a test and the resulting solo decrypted MP4s seem to play fine, but when I try to use MKVMerge the resulting file doesn't play as video and strangely it thinks the codec is QT?

EDIT: MP4 out of ffmpeg was fine. Not sure what went wrong with mkv.

[mike94]

Glad it works now, I usually prefer ffmpeg myself:

ffmpeg -i decrypted.mp4 -i decrypted.m4a -vcodec copy -acodec copy your_movie.mp4

This'll leave all your streams untouched and just merge them together into one file.

Yup, that's what I did. Perhaps it's one of those typical live streams with a few wonky headers that confused mkvmerge.

But yeah, all good now ready to download the acts I want later. Thanks.

Can you please help me figure out how to obtain key so I can use it for tomorrow's RaR streams?
I have found MPD with PSSH, but not sure what's the correct license url, is it https://widevine.tvnow.de/index/license?
Also not sure what headers I should put into cdrm

Thanks in advance!

CDRM won't work in this case, the license server blocks all requests from there.
You can use WKS or the widevine_keys script - but you'll need your own CDM with that.

License URL is correct, headers are those from the browser's request to that license server.

CDRM works for this service if you provide a working proxy:

This is the proxy I used: http://user-uuid-60b5fd6021224914ae7b263c46142167:434ca58478e7@181.119.30.35:22223

Sweet, is this a regular HTTP proxy or where do you find those?

[lomero]

Yup, that's what I did. Perhaps it's one of those typical live streams with a few wonky headers that confused mkvmerge

But yeah, all good now ready to download the acts I want later

don't use mp4decypt and ffmpeg to mux ... useless

use N_m3u8DL-RE all-in-one (need to have mp4decypt and ffmpeg on same folder with N_m3u8DL-RE)
N_m3u8DL-RE -M format=mkv --key xxxx "https://mpd" --save-name xxx

-M format=mkv or -M format=mp4

N_m3u8DL-RE -M format=mkv --key xxxx "https://mpd" --save-name xxx

-M format=mkv or -M format=mp4

Tried that and didn't get a single file output, just folders of m4s files. Added --live-real-time-merge which gave me an MP4 video and M4A audio file that were both pre-decrypted, couldn't get it to output straight to one muxed file though.

I assume -M doesn't work because it's never actually "done".

[lomero]

yes, folders with m4s files is right. this is all video segments

but end of download, ffmpeg can merge all segments into one final video file mp4 or mkv
no need to add --live-real-time-merge the process is automatic

only this does not work when the key is wrong, so RE can't decrypt then no mux
but the key is right. have you mp4decrypt on same folder with RE ?
if yes, try to use shaka. then add --use-shaka-packager to RE command

Yes, all three exes in the same folder.

As it's a live stream there is technically no end of download, I just stop it manually with CTRL+C, so that is probably why?

[lomero]

ah i'ts live

so use

--live-record-limit <HH:mm:ss>

[vikwinchester]

ah i'ts live

so use

--live-record-limit <HH:mm:ss>

what is the best command for N_m3u8DL-RE to record a portion of ongoing Livestream? just wanna make sure I won't ended up with broken files. Can you please check if this is the correct way?

--key XXX:XXX
--save-name recording
“1.mpd"
--append-url-params
--mp4-real-time-decryption
--live-real-time-merge
--live-record-limit 00:01:00
--mux-after-done mp4

[lomero]

it think the best reply is <try yourself>

some site are different. anyway some command are not relevant:
--append-url-params
--mp4-real-time-decryption
--live-real-time-merge > better download all segments, decrypt and mux
--live-record-limit 00:01:00 > with this command you can record 1 min only. it's right for test only
--mux-after-done mp4 > i prefer -M format=mkv but it's the same

and for mux live better use shaka > --use-shaka-packager

--mux-after-done mp4 > i prefer -M format=mkv but it's the same

So it's better to use it just for downloading segments, and manually merge and decrypt them with mp4decrypt and mkvmerge, right?

[lomero]

no. RE after download process can decrypt and mux. movie or live, the same

[vikwinchester]

no. RE after download process can decrypt and mux. movie or live, the same

that will be done automatically? I just need to remove “--mp4-real-time-decryption --live-real-time-merge” I guess?

[lomero]

again. your better way is test yourself. follow my post#19 and rip your live for 10 min only. just for test

and report here your considerations

It hasn't been started just yet. But I will try ASAP. Thank you for answering my noob questions, I really appreciate it.
