Chinese Channels (CC-TV) not working #902

Madkat2 · 2022-06-28T13:16:48Z

Describe the bug

None of the CC-TV channels are working

To Reproduce

Steps to reproduce the behaviour:
1.Open Any CCTV channels
2.error message
3.JSON decoder error
4.error log fails to upload

Expected behaviour

I expected them to work, they used to work on an older version

Actual behaviour

All channels not working

Screenshots

If applicable, add screenshots to help explain your problem:

Your environment

Android
iOS
Linux
OSX
Raspberry-Pi
[X ] Windows
Other
Operating system version/name:
Kodi version:Matrix latest
Catch-up TV & More version:latest stable and beta, tried both
Installation method:from repository

Additional context

I posted this the other day, I was told the channels are geoblocked, I have since found this is not the case, CC-TV 1-17 are available to watch via their website or app, I am not in China and had no problems watching

Should be fixed in the next beta, thanks to Darodi.

Madkat2 · 2022-06-28T19:38:11Z

That would be great, thanks a million, I'll keep an eye out for the next release and give it a shot

Unfortunately, only CCV1 is fixed. Others channels do not offer no-drm stream.
So, more work is requested to make these channels working.

darodi · 2022-06-29T11:21:41Z

I must admit I've only tested CCV1 :P
I'll have a look.

Madkat2 · 2022-06-29T12:09:47Z

That's good to hear, hopefully the other channels will be ok, thanks for having a look at it, much appreciated

Well... using the web, the drm is not easy...

the live stream url comes from

https://vdn.live.cntv.cn/api2/liveHtml5.do?channel=pc://cctv_p2p_hdcctv2&client=flash&tsp=xxxxxxxxx&vn=1537&vc=yyyyyyyyy&uid=&wlan=

where xxxxxxxxx and yyyyyyyyy come from
https://js.player.cntv.cn/creator/liveplayer.js

xxxxxxxxx= the value of
vdn_tsp =new Date().getTime().toString().slice(0,10);

yyyyyyyyy = the value of
vdn_vc = setH5Str((vdn_tsp+vdn_vnFlash+staticCheck_Flash+vdn_uid)).toLocaleUpperCase()

where setH5Str is a javascript function

Without those 2 parameters, the stream has audio but the image is scrambled.

We must find a way to execute javascript functions in python.

Another option would be to check the streaming app

The best is to translate the javascript function in python and attach the code in a separate file. I am not enthousiast in shipping a new python module in CUTVM.
I think it would be a good idea to create in the resource/lib folder a new file gathering all the (future ?) drm functions.

darodi · 2022-06-29T19:19:13Z

In this case, yes, the function has a static code, it's not generated dynamically. We can translate it one time.
I hope we will not come across such a case in the future. (Dynamic function)

darodi · 2022-06-29T23:08:18Z

I managed to translate the function :)

expected (breakpoint in the javascript in the browser): 50108D777F1114A9BFBBA24A07A006CE
eval result for js in js2py: 50108D777F1114A9BFBBA24A07A006CE
result with translated code in python: 50108D777F1114A9BFBBA24A07A006CE

I'll test all live feeds and commit tomorrow if everything is OK.

darodi · 2022-06-29T23:23:42Z

aargh... the translated python still uses

from js2py.pyjs import *

joaopa00 · 2022-07-04T08:06:48Z

It looks like the drm function is only md5sum function. Actually, if it is the case, it should not be hard to find a python already-made version.
md5sum function

EDIT: It seems that Kodi supports the hashlib library. So, job is done already.

darodi · 2022-07-04T16:16:09Z

@joaopa00

the beautified code is here.
How did you find it is a md5sum?

I only googled "var c=(65535&a)+(65535&b)" :D

La fonction md5 de hashlib donne le même résultat que la fonction utilisée par cctv. J'ai vérifié.
Mais ce n'est pas suffisant. Soit un vdn_uid valide est nécessaire, soit il y a quelque chose qui m'échappe.
tsp = str(int(time.time() * 1000))[0:10] #tsp = '1657014984' print("tsp = %s" % tsp) keys, vdn_uid_hash = Fingerprint2.Fingerprint2().generateFingerprint() vdn_uid = str(vdn_uid_hash).upper() print('vdn_uid = %s' % vdn_uid) seed= tsp + '1537' + 'B4B51E8523157ED8D17ADB76041BCD09' + vdn_uid print(seed) vc1= hashlib.md5(seed.encode()).hexdigest() print("vc1= %s" % vc1) vc = str(vc1).upper() print("vc = %s" % vc) live_id = 'cctv_p2p_hd%s' % item_id resp = requests.get( URL_LIVE + '?channel=pc://%s&client=flash&tsp=%s&vn=%s&uid=%s&wlan=' % (live_id, tsp, vc, vdn_uid), headers={ "User-Agent": web_utils.get_random_ua(), 'Cache-Control': 'max-age=-1, public' })

That's a pity, thanks for all your efforts, much appreciated. I'll keep an eye out for future updates, hopefully they might work at some point, thanks again
