Why are people still messing around with pssh?

Mpd and license cURL is the way to go! Use the kit in my sig.

The method did not work, I tried it many times

[imr_saleh]

block license request and try again

[aletaladro]

block license request and try again

also tried without success

[larley]

Just look at the Error Code in the Nagra Docs. Error code 1001 for example clearly states that your request is malformed.

[A_n_g_e_l_a]

The method did not work, I tried it many times

Of course it works. if it plays in the browser then my script will get it as it sends exactly what the browser sends apart from CDM data

There are three provisions otherwise:-

1. The token is one-time use only - this can be over come by blocking the request, in developer tools, from being sent so your use will be the first.
2. the token times out very quickly - depends how quickly it expires whether you can get it by hand or not
3. The mpd is re-written by javascript straight after a browser request - again a request block may help

So this smells like vdocipher and as such not permissible to discuss here. Much vdocipher is protecting courseware and I feel uneasy about ripping some small guy trying to earn a crust.

Try WidevineFetch (in my signature)

Well if as he claims allhell3.py doesn't work just pasting a fetch instead - but using exactly the same browser data - isn't going to work either. is it?

[Obo]

Hell, yes, it should work with your tool as well. Maybe using a GUI makes it easier for some people, who knows...

Nice tool btw, @larley

[A_n_g_e_l_a]

Naa, not exactly the same, @larley's script only uses the fetch for the license request and puts it all together from there. But hell, yes, it should work with your tool as well.

Nice tool btw, @larley

if he used Chrome only then fetch-all is an option. So it would be possible to parse out the mpd, init,m4f and the license. Although with no standard for naming the license, parsing accurately would be big a problem.

[larley]

Why would I need to utilize that function if all I need is the License URL (and the corresponding headers/body)?

Clearly, it would allow download to be automated too, rather than just providing keys..

Great! You did understand first off. I thought it strange you seemed not to. Playing a boys game I guess?

No contradiction; just a level of difficulty to surmount. We know the method is always going to be POST - so that reduces the field dramatically; then looking for the keywords we know are used in license requests will probably find most. And since the url of the segments is there looking for pssh in the segment0 would be a good way to get pssh. So fetch-all could provide mpd, pssh, license; then downloading is a given.

[larley]

Great! You did understand first off. I thought it strange you seemed not to. Playing a boys game I guess?

You were the one who didn't get the point of the program, so I asked why you were trying to retrieve other parameters too. But even after asking a second time you still didn't get the point.

I'll explain it, just for you (because I'm a kind person):
The program's "slogan" is built around the idea of retrieving keys from just one request/click in your dev tools. It's supposed to make life easier. Adding more features (like what you suggested) doesn't make it easier.
Another reason why I didn't implement it is because I didn't want my program to become your 'allhell2' script (a so-called favor).


Anyways, I've already created what you were thinking of with the all-in-one solution, it's just not released yet.
