Now that I managed to retrieve a stream, I would like to get log from librtmp.
According to ctypes documentation and given functions signatures from log.h/log.c, I wrote this in my code:

CMPFUNC = CFUNCTYPE(c_int, c_int, c_char_p, c_void_p)
def logCallBack(level, message, va_list):
    dll.RTMP_LogPrintf(message, va_list)
    return 0

mLogCallBack = CMPFUNC(logCallBack)
...
dll.RTMP_LogSetCallback(mLogCallBack)

but instead of printing a nice readable log, I got a dirty output:

I also tried to print "message" in my logCallBack() function but it gave me strings without values:

%s, ... connected, handshaking
%s: Type Answer   : %02X
%s: Server Uptime : %d
%s: FMS Version   : %d.%d.%d.%d
%s: Handshaking finished....
%s, handshaked
%s: fd=%d, size=%d
Invoking %s
%s: fd=%d
%s: server BW = %d
%s: fd=%d
%s: client BW = %d %d
%s: fd=%d
%s, received ctrl. type: %d, len: %d
...

I've been trying for almost 5 hours, digging into the web looking for a solution unsuccessfully.
That 's why I'm asking for help.

Thanks in advance.
