How do I post parameters to stream with ffmpeg

[Piotr Kuzminski]

Hi,

Is is possible to post any parameters to RED5 using ffmpeg?
FFFMPEG says that:
https://www.ffmpeg.org/ffmpeg-protocols.html#toc-rtmp

1. So this shouldn’t be valid?

ffmpeg -i input_file -f flv "rtmp://user:pass...@127.0.0.1/oflaDemo/video"

But it does not working.

2. Or maybe additional parameters:

ffmpeg -i input_file -f flv "rtmp://127.0.0.1/oflaDemo/video?arg1=val1&arg2=val2"

Is there any way to send parameters with ffmpeg? I have tried may options but nothing seems to work.

My bad!
I was using string:

"rtmp://127.0.0.1/oflaDemo/video?test"

And that gave me error:

rtmp server sent error

But when I added value to argument it is working properly, so do like this:

"rtmp://127.0.0.1/oflaDemo/video?test=value"

Hope this will help someone.

So my next question is how and when do I read those parameters?
Do I read them at streamPublishStart form IBroadcastStream object?
Or do I read them appConnect from IConnection object?

Yes , it is possible. 

and check this documentation : 

https://www.ffmpeg.org/ffmpeg-protocols.html#rtmp

if you're using the latest ffmpeg , you should keep the rule of parameter. 

check rtmp_conn

.

Parameters are passed on the connection object not stream object. Although you can read connection anywhere using red5 getconnectionlocal but it's best to read it in connect or appconnect methods. 

Check: conn.getConnectParams().get("queryString")

Thank you Rajdeep Rath!
Thanks to your answer I found and followed this topic:
https://groups.google.com/forum/#!msg/red5interest/2lZuuZX4iMc/sAT0u1ffAfQJ

But when I do this:

    public boolean appConnect(IConnection conn, Object[] params) {
        String parameters = String.valueOf(conn.getConnectParams().get("queryString"));
       
        log.info("connected with parameters: "+parameters);
        log.info("total clients  "+conn.getScope().getStatistics().getTotalClients());
    }

And than I post:

ffmpeg -f x11grab -s 640x480 -r 24 -i :0.0+600,120 -c:v libx264 -fflags nobuffer -preset fast -pix_fmt yuv420p -minrate 50k -maxrate 100k -bufsize 200k -s 640x480 -threads 0 -f flv "rtmp://127.0.0.1/test/glosno?are=yousure&not=4sure"

And here's what I got:

[INFO] [RTMPConnectionExecutor#5W56JWZSNQLWL-1] org.red5.demos.test.Application - connected with parameters: null
[INFO] [RTMPConnectionExecutor#5W56JWZSNQLWL-1] org.red5.demos.test.Application - total clients  0

Seems it does not working. I'm using 1.0.4 red5 version.

Am I doing something wrong?
