rtmp_publish example does not working

[tebin]

publish : https://github.com/nareix/joy4/tree/master/examples/rtmp_publish
server : https://github.com/nareix/joy4/tree/master/examples/http_flv_and_rtmp_server
with this server,
i tried to publish flv data to server but failed.
// as same as: ffmpeg -re -i projectindex.flv -c copy -f flv rtmp://localhost:1936/app/publish
when using command ffmpeg, it working but rtmp_publish.go not working.
when i check log in server side, example of publish print [Accept].
I can't seem to get to the parse URL
Is there anyone how to working it ?
