Description

At first glance, https://www.vrt.be/vrtnu/a-z/appel-d-urgence/2/appel-d-urgence-s2a1/ is the only video on VRTnu that returns this kind of error, so the priority is not that high at the moment 😉. But of course you never know if this will happen with multiple videos in the future.

When I open the URL in my browser, first an advertisement is played as a separate video before the main video starts. With all the other videos on VRTnu, the main video starts immediately and any advertising is incorporated in it.

For any work on this you must provide reproducible environment.

[laurensscheers]

Indeed, this program can only be viewed within the EU with a Belgian account.
Now I have tested some things:

• When I use a VPN connection from Belgium to a non-EU country, I get the same black screen as in the comment above.
• With a VPN connection from Belgium to another EU country, I have to enter a Belgian mobile phone number.
  
• When I watch the video in Belgium without the usage of a VPN, I don't have to enter a mobile phone number and I have never linked one to my account.

I therefore assume that a VPN to Belgium should suffice to reproduce the environment. Can someone please confirm this?

[laurensscheers]

Of which issue is this a duplicate?
Because I have searched through some other reported issues with VRTnu and for all those I have tried I can confirm that, if the url is still alive (#20384 for example), it can still be downloaded without any problem.
So this issue seems a new one to me.

[remitamine]

it's the same error but caused by a different problem, so it's not actually a duplicate, but all the formats served for this video are DRM protected, which youtube-dl does not support.

[laurensscheers]

I already feared that it was DRM-protected 😒. Is there a way I can get an overview of all the present streams, including the drm-protected ones? I thought this could be found in the manifest file, but unfortunately this is not the case.

For example: https://www.vrt.be/vrtnu/a-z/we-were-three/2017/we-were-three/

a part of the manifest file:

The available formats:

format code   extension  resolution note
HLS_AES-220   mp4        416x234     220k , avc1.42C01E@ 143k, 25.0fps, mp4a.40.2@ 62k
HLS_AES-485   mp4        480x270     485k , avc1.42C01E@ 363k, 25.0fps, mp4a.40.2@ 93k
HLS_AES-872   mp4        640x360     872k , avc1.42C01E@ 728k, 25.0fps, mp4a.40.2@ 93k
HLS_AES-1184  mp4        768x432    1184k , avc1.42C01F@1023k, 25.0fps, mp4a.40.2@ 93k
HLS_AES-2085  mp4        960x540    2085k , avc1.4D401F@1873k, 25.0fps, mp4a.40.2@ 93k (best)

So even though the URLs in the manifest file show that only DRM streams are available, downloadable AES encrypted streams are available too. Where could I find these?

[remitamine]

it looks like a server issue on remix-cf-vrt.akamaized.net domain, the URL(https://remix-cf-vrt.akamaized.net/remix/18f7b87b-2715-490c-9ac6-8f05fbf5c7e4/remix_aes.ism/.m3u8) for AES formats return HTTP Error 415: Unsupported Media Type, while on the second(working) URL, the formats are served from ondemand-cf-vrt.akamaized.net.
