livestream encrypted or not ?

[dxellas]

Hello everybody,

I would like to know if the geoblocked livestream here is encrypted or not: https://www.megatv.com/live/

With NordVPN and greek IP it is playing but I cannot figure out its url after the ad has finished so I assume that it is encrypted.

Is there a way to find it so that I can watch it on any device instead of only in a browser ?

Thanks for your interest.

In Firefox you can turn DRM off in the settings.
If it still plays you can safely infer it's not DRM protected ....

[dxellas]

Well I have disabled DRM and restarted firefox.
It is still playing but I cannot find the url by using the addon "The Stream Detector" nor does my paid Internet Download Manager show it up.

Are there other methods of encrypting besides DRM ?

it's using wss

Thank you all.

What is wss ?

An encryption method, a different protocol like http(s), udp ?

Does this mean that the wss url cannot be played outside the website ?

I would like to have it on my Enigma² receiver for timer based recordings or on DVB Viewer Pro.

[larley]

It's a WebSocket connection with TLS.
The stream itself is not encrypted but you'll need some kind of code to attach it to anything.

[dxellas]

Well this "some kind of code" seems to be the problem.

I have tried to play it on SMPlayer, vlc, DVB Viewer Pro
as

wss://ume3-edge-01.cdn.vindral.com/subscribe?channelId=alteregomedia_megatv1_ci_6cc490c7-e5c6-486b-acf0-9bb9c20fa670&sessionId=e51e487f-5300-4497-a5cc-0f39e8694c4f&clientId=22f176af-57d9-4337-9700-0c4756db8686&audio.bitRate=128000&audio.codec=aac&video.width=1024&video.height=576&video.bitRate=900000&video.codec=av1&burstMs=2000

and on OpenPLi and OpenATV with installed streamlinkproxy plugin

#SERVICE 5002:0:1:10:10:0:0:0:0:0:http%3a//127.0.0.1%3a8088/wss%3a//ume3-edge-01.cdn.vindral.com/subscribe?channelId=alteregomedia_megatv1_ci_6cc490c7-e5c6-486b-acf0-9bb9c20fa670&sessionId=e51e487f-5300-4497-a5cc-0f39e8694c4f&clientId=22f176af-57d9-4337-9700-0c4756db8686&audio.bitRate=128000&audio.codec=aac&video.width=1024&video.height=576&video.bitRate=900000&video.codec=av1&burstMs=2000

both with no success.

Maybe somebody with programming abilities can succeed running it.

Looks to be a hard nut for common folks like me.

[larley]

The code snippet I made a while back from post#5 will record your live stream to a video and audio file.

The problem here is that the data coming from Vindral is in a proprietary format. If there's a standardized way in which VLC could receive video data through WebSockets you'd need to translate it to that or build fragments + an HLS playlist.

[dxellas]

I highly appreciate your interest and propositions but with my restricted knowledge I cannot go any further.

The optimum would be the url to be played in my Enigma² receivers. Then I could set timers over the EPG. But for this stream this just seems far too difficult.

Thank you for spending time and clearing my initial question.
