All Hell Let Loose!

[A_n_g_e_l_a]

Just tested with https://bitmovin.com/demos/drm/ under Chrome 129 for Linux
'https://licensing.bitmovin.com/licensing'
Same message from GUI version
Could not parse license_message as a SignedMessage, Error parsing message

Quite right Damon. The script is giving you exactly the correct response to the incorrect inputs you've given it.

Instead of throwing aspersions on a script you might profitably learn something by reading the Temple of Doom trilogy in the stickies.

Therein you may find https://cwip-shaka-proxy.appspot.com/no_auth is the license url and you'll need the curl of that!!

[Edit: Sorry I see you've previously posted you can do the following already.

My first post of #139 (https://forum.videohelp.com/threads/415090-All-Hell-Let-Loose!/page5#post2752610) seemed to vanish last night with no explanation (back this morning)

I thought, "Ok!" and so just wrote the request in: #140 (https://forum.videohelp.com/threads/415090-All-Hell-Let-Loose!/page5#post2752612).

Yes that man without hair, Richard, who runs this site, - they call him bald-rick - likes to check for spam; so he reads all new posts before they get put up

I've sent you a PM with solution. Yes I got hooked in! It has an extra button - coloured to indicate availability.

# Command to extract subtitle track (track index assumed to be 0)
command = ['ffmpeg', '-i', f'{video_path}.mkv', '-map', '0:s:0', srt_file]

This works great! :)

OK. Horses for courses, But at least stop ffmpeg filling acres of screen space proclaiming itself.

command = ['ffmpeg', '-loglevel', 'quiet', '-hide_banner', '-i', f'{video_path}.mkv', '-map', '0:0', srt_file]

Anyway, all feedback for v7. What would be really useful is a tool that could just get me the subtitles.
Normal v6 script for Video and Audio. Which is excellent.

Just subs? No, not from me. It seems you are well placed to do that yourself. :)

But a bit of history for you... In the beginning there was a script called l3.py which needed pssh and licence URL plus a headers file and a working CDM to give you keys.
We now have the Hell3 family which takes just the mpd and licence cURL and downloads and decrypts -unseen to the user.
To adapt hell3 too far away from its roots is not on my agenda. It is a key getter and an all-in-one downloader.

The beauty of python scripts is that you have the source code to adapt as you wish.

n_m3u8dl_re_command = (
f"N_m3u8DL-RE '{mpd_url}' {keys} "
f"--save-name 'E:/MakeMKV DVD Reads!/{self.video_name_entry.text()}' "
"-mt "
"-M:format=mkv:muxer=mkvmerge"
)
self.n_m3u8dl_re_output.setText(n_m3u8dl_re_comman d)

subprocess_command = [
'N_m3u8DL-RE', mpd_url
] + keys.split() + [
'--save-name', f'E:/MakeMKV DVD Reads!/{self.video_name_entry.text()}',
'-mt', '-M', 'format=mkv:muxer=mkvmerge'
]
self.subprocess_output.setText(str(subprocess_comm and))

Can't see what is wrong at 02:00. Sadly, must go to bed...
