Hi All,

Can you tell me the syntax to send a raw output of gstreamer to an exteranl

I have tried the below with no luck


gst-launch -v gstrtpbin latency=100 name=rtpbin  buffer-mode=none
uridecodebin uri="rtsp://" buffer-size=200
buffer-duration=200 download=false name=decode decode.  ! queue  ! 
ffmpegcolorspace ! videoscale ! queue  ! capsfilter 
caps="video/x-raw-yuv,width=640,height=352,framerate=(fraction)25/1" !
fdsink fd=1  | ffmpeg -i pipe:1 -re -acodec libfaac -ar 22050 -vcodec
libx264  -f flv rtmp://
