Two network interfaces

How do I get EMP to select which inteface I want to use to attach to multicast IP's?

[IvanR]

For receiving multicast streaming from certain interface, URL should be in following form:   
elecard://group:port[[:s=server][:i=interface][:t=payload_type]]/type

payload_type =   m1s, 2p, m2t

type =   rtp, udp

Example:
elecard://234.5.5.5:10201:s=192.168.57.14:i=192.168.57.23:t=m2p/udp

What is the payload type for AVC/H.264?

[IvanR]

Correct values for payload:
payload_type = m1s, m2p, m2t

If you make streaming H.264 in MPEG2TS you should use m2t payload.

If you make streaming AVC+AAC as elementary streams, you can't receieve data using this method, because elementary streams need description in SDP format for configure receiving part. For example you can receive SDP from RTSP server via RTSP connection.
