Can't receive EOS message on bus

[pushforce]

Hello.

I creating pipeline which transform WebRTC stream to hls (webrtcbin as 
src, hlssink2 as sink). When i want to stop pipeline i send EOS event to 
it, but not receiveng EOS message on bus. I tried to set 
'message-forwarding' property on webrtcbin and hlssink2 but this does 
not helpd.

Maybe i try to stop pipeline incorrectly. What i doing wrong?
