Not able to listen to the stream coming from webcaster client #744

Closed vatsalkgor closed 5 years ago

vatsalkgor commented 5 years ago

Hi, Please forgive me if i post something that was previously answered as I am a noob in liquidsoap. I have researched extensively but was not able to find the solution that's why I am opening the new Issue.

First of all I would like to tell what I want to do. I want to make a radio station in my college that can broadcast live streams coming from different users. So I googled it and found that WebSocket is a protocol that provides full duplex client and server side communication. I found the implementation in Webcaster.js by @toots.

So I am using this link Webcaster to generate the stream. (I have not cloned the repo just using github.io link to generate the stream.)

My liquidsoap code is 

set('log.file.path','/tmp/harbor.log')
set("harbor.bind_addr","0.0.0.0")
set("harbor.verbose",true)

radio = mksafe(input.harbor("mount",port=8080))
output.icecast(%mp3,host='localhost',port=8000,password='hackme',mount='harbor',radio)

If I run the script without mksafe then I get source fallible error. The logs in the logs file says

One point to be noted here is that I am using an old liquidsoap v1.1.1

Can anyone tell me what is the issue here??

vatsalkgor commented 5 years ago

saw issue #276 and updated to latest liquidsoap using opam. However the porblem is still not solved. in the log file I can see that the connection is successful but suddenly after i get error like 'source failed(no more tracks) stopping out...' Here is my .liq file for reference.

set('log.file.path','/tmp/harbor.log')
set("harbor.bind_addr","0.0.0.0")
set("harbor.verbose",true)
set("log.level",5)

radio = input.harbor("/mount",port=8080)
live = fallback(track_sensitive=false,[radio])
output.icecast(%mp3,fallible=true,host="localhost",port=8000,password="hackme",mount="harbor",live)
pl1 = mksafe(playlist("playlist1.txt"))
output.icecast(%mp3,host="localhost",port=8000,password="hackme",mount="pl1",pl1)

the playlist1 is successfully played on icecast2 but i can't see mount point "harbor" in the icecast.

Hi,

It looks like the webcaster client is not sending any data. Have you looked at the logs on the browser's side?

vatsalkgor commented 5 years ago

First of all thanks for reply.

Yes, you are right. At first the browser was saying: SecurityError: The operation is insecure.

Then I followed the SO answer which fixed the above issue. It is now working in Firefox.

Then I tried to do the same with Chromium. But found that the song is not even playing in the browser. It says that the "AudioContext must be resumed or created after a user gesture on the page" followed by a more information link

So I guess that the way webcaster is written, does not support this change in google chrome / chromium.

P.S. This change in chrome/chromium is done after version 66 in May 2018. However, I have not tested this issue in versions before 66.

Thanks for reporting this. I'll have to test the code. The web audio support is constantly improving and it's possible that the code is now outdated.

Great. As of now I am closing the issue. Please let me know if there is any update on webcaster client.

@vatsalkgor Should be fixed now! Try it at: https://webcast.github.io/webcaster/
