Help!!!
Hello,
The RPC documentation may have been outdated for the 2.21.0.
It is now updated: https://docs.openvidu.io/en/2.21.0/developing/rpc/
Please, take a look at the methods you have implemented and see if there are any changes required.
Cheers.
@pabloFuente
Still no problem solved.
Is there no way?
The line throwing a NullPointer is related to the token of the participant joining the session. How did you joined the user owning the stream to the session? You must still use a proper token: https://docs.openvidu.io/en/stable/cheatsheet/join-session/
@pabloFuente
I am trying to apply it to unity.
The token was used as a return value by calling api/session/<SESSION_ID>.
What is suspicious is the sdpOffer value. Is it ok to be long?
sdpOffers are long. There is probably no problem in the publishVideoRPC operation. The problem is that your token is not well formed. The Connection associated to it lacks property "record": https://docs.openvidu.io/en/2.21.0/reference-docs/REST-API/#post-connection
Carefully review your token creation process.
@pabloFuente
I performed joinRoom and publishVideo using the token that came out of calling with the API you mentioned, but the same error still appears.
https://YOUR_OPENVIDUSERVER_IP/openvidu/api/sessions/SESSION_ID/connection
It seems that the body is needed at the same time as the call, so I wrote it as follows.
string uploadBody = "{"type": "WEBRTC"," +
""data": "My Server Data"," +
""record": false," +
""role": "PUBLISHER"," +
""kurentoOptions": {" +
""videoMaxRecvBandwidth": 1000," +
""videoMinRecvBandwidth": 300," +
""videoMaxSendBandwidth": 1000," +
""videoMinSendBandwidth": 300," +
""allowedFilters": [" +
""GStreamerFilter"," +
""ZBarFilter"" +
"]" +
"}" +
"}";
I am sorry, but this is hard for me to keep up with the little information you are providing. I really don't know what this phrase means: "It seems that the body is needed at the same time as the call, so I wrote it as follows.". What do you mean by the body is needed at the same time as the call?
@pabloFuente
Sorry, I'm Korean. So English very weak.
If you look at the documentation, when calling https://YOUR_OPENVIDUSERVER_IP/openvidu/api/sessions/SESSION_ID/connection
I understand that the following syntax is required.
{
"type": "WEBRTC",
"data": "My Server Data",
"record": true,
"role": "PUBLISHER",
"kurentoOptions": {
"videoMaxRecvBandwidth": 1000,
"videoMinRecvBandwidth": 300,
"videoMaxSendBandwidth": 1000,
"videoMinSendBandwidth": 300,
"allowedFilters": [ "GStreamerFilter", "ZBarFilter" ]
},
"customIceServers": [
{
"url": "turn:turn-domain.com:443",
"username": "usertest",
"credential": "userpass"
}
]
}
If you call it without syntax, an error occurs.
This was not a bug in OpenVidu, but some kind of wrong parameter issue when consuming RPC protocol (https://openvidu.discourse.group/t/joinroom-message-question/3826)
