set lcmd0= -vcodec flv -g %gg% -b:v %bb% -r %fps% -s %ss% -aspect %aspect%
-an -benchmark
set lcmd1= -cmp 2 -subcmp 2 -mbd 2 -flags -aic-cbp-mv0-mv4 -trellis 1

rtmp://.........../oflaDemo playpath=oflaDemo/canal1 live=1 : Invalid
argument

I did mask server address 

It seems there are discrepencies between 
vcodec from webcam and 
vcodec to rtmp which must be flv 

Is there something which I can modify  ? 
Is there a way to pipe on windows (from webcam to temp_file , and temp_file
to rtmp 
Allowing to reencode to AVC to rtmp stream ?)

Thanks and have a nice christmas fest
