Restreaming RTMP from room - error

Hi, 
Im trying to restream (audio+desktop screen) from OpenMettings to web page. I already found that to do this I need to find Broadcast_ID (here in mail from 2 years ago: http://osdir.com/ml/openmeetings-user/2010-05/msg00083.html). But it seems that the method from that time still doesnt work ( getRoomWithCurrentUsersById - still doesnt return users with their streams), but i found on the list of commands: getRoomsWithCurrentUsersByList (http://code.google.com/p/openmeetings/wiki/SoapMethods#getRoomsWithCurrentUsersByList), and it seems to work just like i want. But i cant get to retrive value from that function. Whenever im running it in REST like that:

 $server_address:5080/openmeetings/services/RoomService/getRoomsWithCurrentUsersByList?SID=9bc2cd438731c1658204e28128083791&start=7&max=3&orderby=room_id&asc=true

im getting: 

<soapenv:Reason><soapenv:Text xml:lang="en-US">unknown</soapenv:Text></soapenv:Reason>

and in the server log i see error:

{start=7 is room_id that i want, i didnt now what to write in max so i wrote 3, but changing this numbers dont repair anything}

Maybe im doing smth wrong - because my usuall flow of commands to get value always creates new one:

1) im using /UserService/getSession to get session id
2) then im logging user: UserService/loginUser?
3) then im setting roomhash : UserService/setUserObjectAndGenerateRoomHash

and since i cant get any information here im doing:
4)/openmeetings/?secureHash <- this creates new user in DB but now im able to retrieve data using session ID


If someone has any info how to correctly retrieve stream of data from openmeetings i will be thankfull

Re: Restreaming RTMP from room - error

Posted by Thomas <th...@o2.pl>.

Do you mean: getFlvRecordingByRoomId function and similars to them - if yes than i have no idea how to get into them to check them. I mean: im following that 4 steps that I specified, from earlier mail, but this time im always getting nil list (despite fact that im recording something during that time in that room)
 
{4 steps:}
 
1) im using /UserService/getSession to get session id
2) then im logging user: UserService/loginUser?
3) then im setting roomhash : UserService/setUserObjectAndGenerateRoomHash
and since i cant get any information right now im doing:
4)/openmeetings/?secureHash &lt;- this creates new user in DB but now im able to retrieve data using session ID that i genereted {but it seems that new user is simple user, not SOAP only user, maybe here is error - but if yes - then i dont know how to simply logon into my existing account without creating new one}
 
 
Maybe you can specify how should I connect to those streams ? (And is it really video only - because i would need audio too).

Maxim added an option to stream video-only stream from the sharing/recording client. The feedback is appreciated.
