problem with ismv files

[m0ck]

Hi.
I cannot decrypt ismv file.
I have no problems with mp4, ts etc.
Are ismv files any different from others?

Example file

key:c739f6a4fea79481ea20144756be335c
KID=5196291eebc145c5ac79f458502b2932

Ismv is a single fragmented segment. You need to merge them first into a single file and then decrypt it.

How?

[Sviests]

Curl is one of the tools that will do that, however commonly youtube-dl or streamlink does that automatically from a manifest url.

[m0ck]

Sorry, I don't follow.
Can you please guide me with the example above?
From the beginning.

Here is the manifest ism link

https://r.cdn-ncplus.pl/vod/store01/BEL_70001673/_/hd4-hssdrm02.ism/manifest

I downloaded it.
The file has the extension ismv and lasts 2.25 mins the same as the video.
So it's not a framgented file, it is a complete file to my understanding.

The file is here

Keys are here:

key:c739f6a4fea79481ea20144756be335c
KID=5196291eebc145c5ac79f458502b2932

How do I decrypt it.
You said I need to merge it first. How do I do it?

It is not a single file:

[generic] manifest: Extracting information
[ism] Total fragments: 73
[download] Destination: fvideo-6000.mp4

And it downloads a 109MB encrypted mp4.

[m0ck]

How did you do that?

[Sviests]

It's just a container (file extension). You actually can just rename it to .mp4 or .ts if you want to and see if anything changes. It's the codec that stays the same no matter what is the container.

[m0ck]

Changing extension doesn't change anything. I still can't decrypt it.
So the question remains. How do I change encrypted ismv to encrypted mp4?

What should I type and where (youtube-dl?) to get this?

[generic] manifest: Extracting information
[ism] Total fragments: 73
[download] Destination: fvideo-6000.mp4

It is not a single file:

[generic] manifest: Extracting information
[ism] Total fragments: 73
[download] Destination: fvideo-6000.mp4

And it downloads a 109MB encrypted mp4.

Did you manage to decrypt it with given key?
As i can see in mp4info track id is 13 but "mp4decrypt --key 13:c739f6a4fea79481ea20144756be335c manifest-manifest.fvideo-6000.ismv out.mp4" doesn't seem to work

[Sviests]

You can't use this provided key. You'd have to get your own when watching the embeded video.

[m0ck]

It just sounds too complicated for me.

[Sviests]

What is the site? Perhaps it has a HLS version
