Decrypt FTA stream How?

[paul92]

Hi all

This is a similar issue to something I was working with before, but a completely new topic all together, so I thought be worth opening a new thread.

I'm trying to decrypt a stream in order to pass the URL to my PVR software.

I have a flask plugin thanks to members here, which is able to fetch the encrypted URL. I also have a key which should in theory open the channels to allow to be re-streamed. I've had feedback that what was provided works fine in apps like Tivimate, but as I have different IPTV servers in different countries which deal with geoblocking, and then pass the channels back to me (all for my personal use), moving to a DRM app simply isn't feasible for me, so my only option is to decrypt what is encrypted, to a URL on the server such as 127.0.0.1:5988/ITV1, I'll then create a playlist with all those endpoints, and then will import them on my main NextPVR server.

BUt before that's done, I find the right commands.

So the way the flask server is set up is that http://127.0.0.1:1984/itvx?channel=ITV redirects to the proper URL whenever it is requested so it redirects to

I have the keys, so it should (at least in my mind) be easy, I've spend honestly the past two days struggling, and I haven't even implemented what I wanted to implement. Once I've finished testing, or I can see I'm getting somewhere I will then implement this on my infrastructure.

I've attempted this

but all I get is errors.

I've been advised that only the accept header is required so I placed this in my headers.json file

The flask code was provided by stupid.345, if I need share it let me know - all credit goes to him...

I now need to get the decryption working..

Thanks

Thanks in advance, however running linux, and this will be implemented on ubuntu infrastructure. Is it essentially the same?

[larley]

Yes, it does work on linux, but I've noticed that it will always play the currently running period which could be an ad, and if it is then it will try to keep playing this period even if it ends (aka. the ad stops), which will freeze the video and give 404 Not Found errors in the cmd

What are possible ways around this?

[larley]

1. Find an option in ffmpeg that automatically switches Periods
2. Use a completely different 'streamer'
(3. Modify ffmpeg and compile it yourself)

[paul92]

The MPD file eventually expires, and needs to be renewed so will put a script in place which automatically does this.

Would FFplay be able to transcode the stream so I could potentially open it with another media player on the network, or does it just open it on that PC? Either way it's a step in the right direction. I've heard something about gyan.dev's ffmpeg build being better at this kind of thing, but seems to be Windows based, and would need to recompile it for Linux.

So I've had some success with FFplay. The stream plays (not all that well, but at least I now know it's working) It's a big step up from nothing for the past few days.


Using ChatGPT, I asked it to convert the stream to FFMPEG which gives me this output

and all the playback gives me is a grey pixellated picture which means assuming is the DRM which hasn't been removed.

My plan eventually would be to have a script deals with automatically fetches the latest mpd file. The flask script automatically fetches the correct MPD when http://127.0.0.1:1984/itvx?channel=ITV is called. so should be as simple has having the flask scripts automatically being refreshed which should allow uninterrupted viewing.

However before any of this is done, I need to be able to view with ffmpeg. Being able to finally view the stream in FFplay is a step in the right direction. Next step is FFmpeg.

Thanks so much

meant ffmpeg. ffplay is the same as ffmpeg but instead of outputting to a file it just displays it
ffmpeg, in this case, whill start a UDP stream

I tried around and got to this command:

ffmpeg -re -i "<itv1 mpd url>" -cenc_decryption_key 06153ec0f57fce3444b29e0f1a3534fa -c copy -f mpegts udp://127.0.0.1:8080

but I'm getting this error in VLC after waiting for ~1 minute:

mpg123 error: mpg123_decode_frame error: A generic mpg123 error.

I wonder if it would have anything to do with headers.

This is the flask script which pulls the valid scrambled URL - I wonder if what's required here can't be used to also decrypt. Someone said that only an accept header is needed.

Here's the content of that flask script

from flask import Blueprint, redirect, request
import requests

itv_bp = Blueprint('itv', __name__)

@itv_bp.route('/itvx')
def itvredirect():
    channel = request.args.get('channel', 'ITV')

    proxies = {
        'http': 'http://localhost:8080',
        'https': 'http://localhost:8080',
    }

    cookies = {
        'SyrenisCookieFormConsent_Itv.Session': '{"tokens":{"content":{"entitlement":{"purchased":[],"source":"","failed_availability_checks":[]},"email_verified":true,"token_type":"bearer","missingUserData":["NoPlanSelected"]}}',
    }

    headers = {
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:126.0) Gecko/20100101 Firefox/126.0',
        'Accept': 'application/vnd.itv.online.playlist.sim.v3+json',
        'Accept-Language': 'en-GB,en;q=0.5',
        'Referer': 'https://www.itv.com/',
        'Origin': 'https://www.itv.com',
        'DNT': '1',
        'Connection': 'keep-alive',
        'Sec-Fetch-Dest': 'empty',
        'Sec-Fetch-Mode': 'no-cors',
        'Sec-Fetch-Site': 'same-site',
        'Priority': 'u=4',
        'Pragma': 'no-cache',
        'Cache-Control': 'no-cache',
        'Content-Type': 'application/x-www-form-urlencoded',
    }

    data = '{"user":{"itvUserId":"{4f129513-1f5b-4dc9-8a2a-b6434e93c938}","entitlements":[],"profile_id":"{4f129513-1f5b-4dc9-8a2a-b6434e93c938}_0"},"device":{"manufacturer":"Firefox","model":"126.0","os":{"name":"Mac OS","version":"10.15","type":"desktop"}},"client":{"version":"4.1","id":"browser","supportsAdPods":true,"service":"itv.x","appversion":"2.228.2"},"variantAvailability":{"player":"dash","featureset":{"min":["mpeg-dash","widevine"],"max":["mpeg-dash","widevine"]},"platformTag":"dotcom"}}'

    response = requests.post(
        f'https://simulcast.itv.com/playlist/itvonline/{channel}',
        cookies=cookies,
        headers=headers,
        data=data,
        proxies=proxies,
    ).json()

    url = response['Playlist']['Video']['VideoLocations'][0]['Url']
    return redirect(url)

That someone was me. But any special headers, cookies or request data are only important to get the JSON data from 'simulcast.itv...'. Once that response gets retrieved by the Flask script, it extracts the dynamic url from the JSON and redirects to it. But following that redirect (to the 'play.dar.itv...' url) just means that any browser, player or script can call that url with the standard headers that it would use for any other url. And those headers are all that's needed to get something to play (as with ffplay) as the url to which you are redirected contains a long list of parameters - meaning any credentials needed are then part of that url.

And to be sure: there is no real 'rotation' of mpd urls, every single requests gets a unique url and you will get a new one if you repeat the request 1 second later. Which means that all requests should pass through the Flask script and follow the redirect that it provides. Only that way are you sure that whatever data is linked to your client, ip address or indeed the itvUserId included in the script is consistent throughout the lifecycle of your request.

Just a thought here: wouldn't it be easier to try setting up the decryption for a channel that doesn't use dynamic urls and isn't geoblocked? Just to remove those two extra moving parts? I think the RTÉ channels fit that description.

Getting RTE is eventually on my to-do list. I'm still determined to find a way to decrypt these streams.
