authentication isnt the issue. Issue is the streams themselves are encrypted with Widevine DRM.
You'd need something to decrypt and then rebroadcast. Like a modified ffmpeg that works with Widevine.
oops. @kor had already answered above me basically the same thing
thanks @kor @matthuisman, like I say ever the optimist! 
I was thinking there may have been a way for instance to have Kodi server do the stream, and then rebroadcast it to channels for playback at the end point, but expect that would break some rules around rebroadcasting content.
@matthuisman any chance the experimental custom channel/strmlink feature just launched for NBC channels might work for Kayo? (e.g. still have fox league in the channels guide, but when we click on it, it opens Kayo and initates the 502 live channel stream) and if that worked, perhaps it might work for the binge live channels too. It would be a small win to have a guide and direct link to the stream.
i still publish a kayo epg Raceday Review - Morphettville so if you can find a workaround for playback - then sure why not. I don't know anything about strmlink etc, so you'd need someone else to help out with that 
It's a new type of custom M3U channel source
I need to work out how to discover the direct link to the live channel (if there even is one)
It's easier to test on iOS. If you're lucky the same links will work on tvOS.
To test a link, send it to yourself in iMessage and click on it.
Start with regular http links. If Kayo has a website for a channel where it streams, try that and see if the app opens instead of the website.
Otherwise you will need to figure out what CFBundleURLSchemes registrations the app has. Sometimes you can google this. Otherwise you would need to check the Info.plist file from the app's IPA file.
It's not an easy process, and many apps simply don't implement deep links to live content so you also need a lot of luck.
Oh right, its all based around the apps...
I was thinking it was some sort of browser integration...
But seems more like app integration?
Itll open the official app to start playing?
Does https:// cause it to open the users browser to the page?
Or are you hoping the app has been setup as a default for certain urls?
Yep its basically an app launcher, aka deep link
Exactly. More details here: Experimental: Stream Links from the Guide via Custom Channels
Many times the app will be registered for certain https url as well.
On android finding the registered schemas is easier, you can look in the AndroidManifest.xml:
<activity>
<intent-filter>
<data android:scheme="nbctve"/>
<data android:scheme="https" android:host="nbc.com/live"/>
</intent-filter>
</activity>
usually the registered schemas/hosts are the same between android and ios.
For kayo you could try these link formats:
https://kayosports.app.link
https://kayosports.com.au/event
https://kayosports.com.au/event-centre
Is there a URL on their website that starts like that? On mobile/tablet/web sometimes you can get a share url which will contain a link like this.
Same time they went DRM they switched to video overlays for their live feeds which start like this
(https://kayo-live-761f422bb93edb7b.akamaized.net/v1/master/b259a4c6c7055dd33d5a9109c9d584b5dd51dd5a/761f422bb93edb7b-hls-drm/out/v1/cebf16d7a1d94e21b59d254e42bb8a1f/index.m3u8?ads).....
Kayo info.plist
may be the version before last
key>CFBundleIdentifier</key>
<string>au.com.streamotion.kayo</string>
looks like kayosports://
<key>CFBundleURLSchemes</key>
<array>
<string>kayosports</string>
</array>Thanks. The scheme definitely opens the app. I am testing on iOS before going to tvOS.
However I haven't been able to directly open a certain page or stream
I have tried all the variations such as event, live etc. I can even see the reference to the event-centre in the inspector.
Is there a trick to finding the page url ?
Did you ever have any luck getting kayo to open using strmlinks?
I couldn't get the browser links to the live channels to implement into schemes for the url calls. The page url just shows browse but I couldn't locate the specific channel source within the inspector unfortunately
Yeah...I guess that means the only way for aussies to use this is with HDMI tool (and a script that clicks on the channel for you)
Unfortunately from my attempts I couldn’t find anything to work either - apart from simply opening the app.
If hdmi for channels does interest you
Foxtel STB with a Hauppauge IR blaster/“tuner” works well using NextPVR as a backend
Sets up a m3u that automatically send the IR signals to change channels.
Instead of using the Hauppauge as the encoder I use a 4K one so I can stream 4k50 sport remotely if I have the speed!
Also I’ve had some success in deep links opening the correct channel of the iOS Foxtel now app - I assume this would be possible with an android hdmi for channels set up.
Shame there is no Foxtel now for tvOS to link to. Unless you’re on android of course
Do these deep links allow you to use Chrome capture for Foxtel Now ?
I think you should be able to, but may require some tweaking.
Gave it a go but my computer couldn’t handle it and the video wasn’t great so didn’t get too far into it.
Links are pretty straightforward, the only other issue I was having was if I changed channels, the previously open channel was interfering with the new stream opening. Was like Foxtel was seeing the previous stream and not letting the next load.
I know the Foxtel TV app doesn’t work with ccwgtv but if it works with any other cheap android sticks or boxes, could be a good idea to use a double hdmi tuner with 2 sticks and adbtuner if you can’t get the chrome capture to work well.
