Issue when downloading stream from la7.it

Hello, when trying to download the following documentary from la7.it I get the error below. I am however able to download other streams from la7.it. How can I fix this issue?

youtube-dl --verbose --no-playlist -o "%(title)s.%(ext)s" https://www.la7.it/atlantide/rivedila7/atlantide-hitler-1922-marcia-su-berlino-01-12-2022-462379

I can add that if I try to download the link below it works:

https://www.la7.it/dimartedi/rivedila7/dimartedi-30-11-2022-462229

I have tried to compare the variable "webpage" in the la7.py extractor file between the link that works and the link that doesn't work. In the link that works, I can find this (which I think has the data that the script is looking for):

src: {"m3u8" : "http://la7-vh.akamaihd.net/i/,/content/entry/data/0/537/0_p881dq0q_0_60gslmxm_1,/content/entry/data/0/537/0_p881dq0q_0_uu0xfins_1,.mp4.csmil/master.m3u8","mp4" : "https://awsvodpkg.iltrovatore.it/content/entry/data/0/537/0_p881dq0q_0_60gslmxm_1.mp4","f4m" : "http://la7-vh.akamaihd.net/z/content/entry/data/0/537/0_p881dq0q_0_uu0xfins_1.mp4/manifest.f4m?hdcore=3.1"},

In the link that doesn't work I cannot find a similar structure. I can only find one line that has "mp4" in it:

window.iosUrl = "https://d6tz2b13nnqzk.cloudfront.net/Atlantide_20221130212400.mp4?Expires=1670025543&Signature=aRAuDxnB....

It looks like the Atlantide show is DRM-protected, while Puntata isn't.

In any case the new yt-dlp LA7 extractor needs to be back-ported.

It looks like the Atlantide show is DRM-protected

Unfortunately, yes 😞 ; the cenc MPEG-DASH manifest is:

https://d3iki3eydrtvsa.cloudfront.net/Atlantide_20221130212400/DASH/Atlantide_20221130212400.mpd

I tried spoofing a mobile UA, got served below manifest:

which, promisingly, generates:

... however, the variant manifests are ALL tainted with AppleFairPlay DRM...

(Google's) DRM is quickly spreading everywhere, like aggressive metastatic cancer 😡 ...

while Puntata isn't

😄 ; puntata = episode; the show's name is "~in~diMartedi" ("on Tuesday" ? ); this non-DRM programme has its manifests served from Amazon,awsvodpkg.iltrovatore.it, rather than CloudFront:

https://awsvodpkg.iltrovatore.it/local/dash//,/content/entry/data/0/537/0_p881dq0q_0_60gslmxm_1,/content/entry/data/0/537/0_p881dq0q_0_uu0xfins_1,.mp4.urlset/manifest.mpd

if I try to download the link below, it works:

https://www.la7.it/dimartedi/rivedila7/dimartedi-30-11-2022-462229

Truth be told, I was a bit perplexed by OP's claim, because when I tried la7.py to be found in the master branch, I failed to initiate a download... Then, after more thorough searching, I realised OP must be using the la7.py version from here, further patched according to this ...

FWIW, and as pointed elsewhere, the patches thus far can only grab the 360p variant for the diMartedi (non-DRM) episode:

So yes,

the new yt-dlp LA7 extractor needs to be back-ported.

FYI, that has been now merged in (yt-dlp) master, result:

Yes, you are correct, I have modified the la7.py extractor as guided by dirkf. It's a pity that it's not possible to download streams of Atlantide as they make really nice documentaries. Having a quite limited data plan in my phone it would be very convenient to be able to download them at home and watch them while commuting.

Just a small correction, you mentioned "inMartedi" but actually the correct name is "DiMartedi" :)

It's a pity that it's not possible to download streams of Atlantide as they make really nice documentaries. Having a quite limited data plan in my phone, it would be very convenient to be able to download them at home and watch them while commuting.

It's all because of d*mn DRM, which is spreading like a plague 😡 ; it's being used mostly to satisfy the studios' demands, as a piracy deterrent, but along the way it impedes legitimate use cases like yours 😉 ... DRM isn't a "deal breaker" for the "real" pirates, so the channels' reason for implementing it becomes moot... If you as a viewer of la7 can exert any leverage whatsoever on them, be vocal about it and let them know how dissatisfied you are about them implementing DRM...

you mentioned "inMartedi" but actually the correct name is "DiMartedi"

Thanks, of course it is, as it's to be found in the programme's URL... I corrected it in the one instance I typed it wrong 😄 ...
