stuck with AES Enc IV file

The m3u8 header

The key file is protected. so ffmpeg and streamlink don't work

streamlink --http-header "Referer=https://view.vzaar.com/19613556/player?uss_token=2.20190217215722.663e996c11a598f7b188885cc0a6734f&apiOn=true&hideFullScreen=true"  --http-header "User-Agent=Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36" --http-header "Origin=https://view.vzaar.com" "https://fable.vzaar.com/v4/uspaes/tBKP830q5ISo/19613556.ism/.m3u8?ts=1550438843&s=p7GyiOX1TtrMGvildn4VsmtVVJo%3D" best -o video.mp4

There's https://github.com/e2iplayer/hlsdl which converts m3u to ts with AES decryption support. Yes, I got a 122 MB data output file but I am not sure if the file is good. I am not familiar with ts files. I know they can be converted with ffmpeg.

Any ideas guys on what direction I can try next

Need link.

Do you have the key file?

[ponens]

Use youtube-dl and ffmpeg with the first instance url.

19613556

It is useful to learn fundamental electronics theory, although this guy's presentation is a bit lacking at times.

@ponens
Noice!! The first url instance, do you mean the .ts url instances?

youtube-dl -f 0  "http://goose.vzaar.com/tXbP_-rRZAzM/19509657.ism?ts=1550506452&s=P68ME9JNiy0rWFkASwA7Dq8gnQY="

??

or

youtube-dl -f 0  "https://fable.vzaar.com/v4/uspaes/tXbP_-rRZAzM/19509657.ism/19509657-a_original=56000-v_original=175000.m3u8?ts=1550506452&s=P68ME9JNiy0rWFkASwA7Dq8gnQY="

I'm doing something wrong

[ponens]

By first instance url, I mean the parent m3u8, instead of the child m3u8.

It turns out that is wrong anyway. I had thought that youtube-dl passed the query string parameters from the parent m3u8 supplied on the command line, to the key url - which is needed to download the key.

But it turns out that the default youtube-dl code does not do this. I was using modified youtube-dl.

I can't think of another easy solution offhand other than to get the key from the browser.

[xyzo]

Retrieving the key, I think will be a bit challenging. I don't think that's an easy solution at all. An easier alternative, I think would be your solution with modified YT-dl. If you don't mind sharing your modified youtube-dl or if you can just elaborate on how exactly is it modified

I found this thread https://forum.videohelp.com/threads/390844-How-to-download-from-this-website trying tube digger doesn't work with m3u8 files. I am not sure how xlmpaler managed to work it out. I am still stuck with this, I do know the Cookie parameters values. Can that be used w/streamlink or youtube-dl to get a valid session? If anybody has a solution pls share your knowledge thanks

[xyzo]

That's the video that Ponens managed to extract from the m3u8 in the first post. @sekininsha

Edit: m3u8 link in the first post was expired
updated it here it is

Tubedigger should detect the video if it is played from the initial webpage where it is located.

[xyzo]

I ran tubedigger but it hangs. it starts google fine but it hangs once I start searching for anything. Can someone think of any other alternatives or if someone is generous enough to help me convert rest of the vids (they are not much lmao

[TubeDigger]

Can someone think of any other alternatives

Everything is fine with my project, but you may think of running System File Checker: sfc /scannow before trying any program.
