Answer for PushIn Stream
Unfortunately, HTTP is not a supported input schema for EMS. However, you can get around it by doing this:
1. If the stream is h264/AAC
2. If the stream is not h264/aac
avconv -i http://IP:port/rtp/IP:port -acodec copy -vcodec copy -f flv -metadata streamName=myNewStream tcp://ems_ip:6666
#2 is re-encoding. If one of the components is already in h264/aac, than just put "copy" for it
If all goes well, than you should have a new stream inside EMS called "myNewStream".
avconv -i http://IP:port/rtp/IP:port -acodec libfaac -vcodec libx264 -f flv -metadata streamName=myNewStream tcp://ems_ip:6666
