Open Broadcast Software as stream source

James Smith · Jun 6, 2017

Hello, we would like to use OBS as the video source to publish to a stream. How can we do this?

Thank you!

Max · Jun 7, 2017

Hello
OBS can encode RTMP stream.
1. Open Settings - Stream menu
Set RTMP URL
Example:

Code:

rtmp://192.168.88.59:1935/live

Here 192.168.88.59 is IP address of WCS server
Set stream key (name)
Example:

Code:

2. Add Video Capture Device in the menu 'Sources' and press 'Start streaming'
Stream is being published to WCS server.

3. Play stream on WCS server.
Open default player like this
https://wcs5-eu.flashphoner.com/demo2/player
Set stream key (name) as 12345 and press play.

On server side you have to disable RTMP keep alives to avoid disconnection of OBS client.
Replace

Code:

keep_alive.algorithm=HIGH_LEVEL

with

Code:

keep_alive.algorithm=NONE

in WCS_HOME/conf/server.properties

Hi Max, thanks for the response.

I've followed the instructions but we are receiving "Could not access the specified channel or stream key, please double-check your stream key. If it is correct, there may be a problem connecting to the server." from OBS.

It appears that we need to enable RTMP and provide an authentication mechanism, since we do not want anyone to be able to stream this way. Can you advise on how to do this?

I've followed the instructions but we are receiving "Could not access the specified channel or stream key, please double-check your stream key. If it is correct, there may be a problem connecting to the server." from OBS.

Make sure
1. WCS server is up and running

Code:

ps aux | grep Flashphoner

should print two processes
2. WCS server is listening port 1935 TCP

Code:

netstat -nlp | grep 1935

3. This port is open on firewall

Code:

telnet 192.168.1.88 1935

Here IP is address of WCS server

Regarding authentication,
WCS can authenticate RTMP connection by parameters from RTMP connection URL.
Example:

As you can see from this screenshot, RTMP connection URL is

Code:

rtmp://192.168.88.59:1935/live?login=alice&password=1234

So you can pass arbitrary authentication data within the connection URL.

Code:

rtmp://192.168.88.59:1935/live?token=1234
rtmp://192.168.88.59:1935/live?login=alice&password=123
rtmp://192.168.88.59:1935/live?id=1&group=33&login=alice&password=123
etc

Upon each connection attempt WCS will send REST/HTTP authentication request to localhost:

Code:

URL:http://localhost:9091/EchoApp/connect
OBJECT:
{
  "nodeId" : "H4gfHeULtX6ddGGUWwZxhUNyqZHUFH8j@192.168.1.59",
  "appKey" : "flashStreamingApp",
  "sessionId" : "d84c47f9-d3ca-464d-ba44-44a0e3970e72",
  "useWsTunnel" : false,
  "useWsTunnelPacketization2" : false,
  "useBase64BinaryEncoding" : false,
  "custom" : {
    "password" : "1234",
    "login" : "alice"
  }
}

As you can see, WCS passes parameter "custom" with authentication data:

Code:

"custom" : {
    "password" : "1234",
    "login" : "alice"
  }

Eventually you can reply with HTTP 200 OK to accept connection or 403 Forbidden to reject RTMP connection.
For more information, please see REST Methods docs:
https://flashphoner.com/docs/wcs5/w.../index.html?method_connect_authentication.htm
By default all requests accepted.

When connecting via rtmp://host:1935/live?token=test and streamName 12345, I see this in flashphoner_manager.log:

Code:

12:37:13,069 INFO  agerRemoteRmiService - RMI TCP Connection(438)-host SEND REST OBJECT ==>

  "useWsTunnel" : false,
  "useWsTunnelPacketization2" : false,
  "useBase64BinaryEncoding" : false,
  "custom" : {

  }
}

  "useWsTunnel" : false,
  "useWsTunnelPacketization2" : false,
  "useBase64BinaryEncoding" : false,
  "token" : "test"
}

However, the OBS application reports the same error "Could not access the specified channel or stream key..."

Apps are as follows:

Code:

> show apps
owner name              appKey            id URL
------------------------------------------------------------------------------------
admin flashStreamingApp flashStreamingApp 18 http://localhost:9091/EchoApp

Configured with app-rest-methods connect and publish. Are we missing configuration to allow rtmp streaming?

Max · Jun 8, 2017

All RTMP streams are allowed by default.
Make sure you have open ports on your server
http://forum.flashphoner.com/threads/open-broadcast-software-as-stream-source.10949/#post-12831
If you provide SSH access, we will able to test with your server and advice with configuration.
logs@flashphoner.com

Max · Jun 8, 2017

You can also attach some screenshots and server logs.
Maybe you have an error in logs.

What is your build number?
Try to update to the latest one:

Code:

service webcallserver update

Max · Jun 8, 2017

From logs I can see you don't have issues with firewall and connection is established.
Perhaps latest version of WCS server will resolve the issue.

James Smith · Jun 8, 2017

Last time we updated was yesterday.

Max · Jun 8, 2017

Here is successfull log.
The difference is your log says:

Code:

command - deleteStream

Our log says on the same place:

Code:

command - createStream

We test the OBS encoder with default settings on Windows 64 bit.
What is your platform? Maybe you test on Mac OS?

I tested with Windows 10 through OBS

James Smith · Jun 8, 2017

Our WCS has been customized, we deleted almost all of the default apps and I have since readded flashStreamingApp per the conversation above.
Is there another app we need to add or a special way to configure it?

Max · Jun 8, 2017

You can backup your database folder and revert database to defaults.
1. Stop server.

Code:

service webcallserver stop

2. Backup database
/usr/local/FlashphonerWebCallServer/database
3. Remove contents from database folder (it will revert database to defaults).
4. Run server

Code:

service webcallserver start

You can use the same procedure to repair backed-up database.

Is there another app we need to add or a special way to configure it?

No. It should be enough.

Please share your server settings or send to logs@flashphoner.com

flashphoner.properties
server.properties
wcs-core.properties
wcs-manager.properties

We will check OBS on Win 10. If it works, it will point to problems with server configuration.
Yo can also try another test. Publish RTMP stream from built-in Flash Streaming example:
https://wcs5-eu.flashphoner.com/demo2/flash-streaming

James Smith · Jun 8, 2017

The issue was resolved by restoring default configuration and then not modifying the flashStreamingApp

Max · Jun 8, 2017

We have successfully tested OBS on Windows 10. It works well too.
Though as we found out, OBS works smooth when encoding preset ultrafast is used.
If encoding preset is not ultrafast, stream is choppy.

James Smith · Jun 8, 2017

Thanks for that Max.
We need to customize which app is used when streaming via rtmp. Currently it's always going through flashStreamingApp, how can we customize this? We need to be able to specify the app in the client's URL used in OBS, ie: rtmp://host:1935/app1 and rtmp://host:1936/app2 so that app1 uses app-rest-methods on server1 and app-rest-methods on server2.

Thanks!

Max · Jun 8, 2017

You can do that in the latest build 2273

Code:

service webcallserver update

Example:

Code:

rtmp://192.168.88.59:1935/live?login=alice&password=1234&appKey=customAppKey

Here parameter name appKey is reserved and will be resolved to a corresponding application key.
Note, if you create application for RTMP injestion, it must be configured with

Code:

com.flashphoner.server.client.handler.wcs4.FlashStreamingHandler

Code:

com.flashphoner.server.client.handler.wcs4.FlashStreamingCallbackHandler

Type

Code:

show apps -d

to see app handlers:

To update main and callback handlers you have to use commands:

Code:

update app -m com.flashphoner.server.client.handler.wcs4.FlashStreamingHandler myApp

Code:

update app -c com.flashphoner.server.client.handler.wcs4.FlashStreamingCallbackHandler myApp

Main handler is internal server-side code working on Client to Server direction.
Callback handler is internal server-side code working on Server to Client direction.

Hello Max, I am using the above advice for streaming from a third party client. The issue I am running into now is that when publishStream is sent to the server and the server returns a 403 but the WCS allows the stream to be created and continues as if a 200 was returned. Here is the part of the flashphoner.log that seems relevant:
