how to create correct pipeline to stream to youtube?

[Борис]

Hi. I'm trying to stream to youtube using this pipeline:
gst-launch-1.0 videotestsrc is-live=1 ! videoconvert ! "video/x-raw,
width=1920, height=1080, framerate=60/1" ! queue ! x264enc tune=zerolatency
! "video/x-h264,profile=main" ! flvmux streamable=true name=mux ! rtmpsink
location="rtmp://a.rtmp.youtube.com/live2/x/0cqu-tet8-fjz4-5daa-40av
app=live2"

but nothing happens after i start it... gst-lauch finishes without any
error after a few seconds
What is wrong here?
