Multicast rtp on Windows with multiple ethernet interfaces

Hi all,

I need to receive a multicast RTP stream on windows on a system that has
multiple ethernet peripherals, but I cannot select the correct multicast
interface using "multicast-iface" parameter.

Under ubuntu I can correctly receive the strean using
*gst-launch-1.0 udpsrc multicast-iface=eth0 multicast-group=239.0.0.105
auto-multicast=true port=16000 ! 'application/x-rtp, encoding-name=H264,
payload=96' ! rtph264depay ! h264parse ! avdec_h264 ! xvimagesink sync=false
async=false*

The equivalent windows version does not work:
*.\gst-launch-1.0.exe udpsrc multicast-iface="ethernet_2"
multicast-group=239.0.0.105 auto-multicast=true port=16000 !
'application/x-rtp, encoding-name=H264, payload=96' ! rtph264depay !
h264parse ! avdec_h264 ! videoconvert ! autovideosink*

The ethernet interface is named "Scheda Ethernet Connessione alla rete
locale (LAN) 2"

If I replace the multicast with a "simple" broadcast I can receive the
stream correctly

Thank you in advance
Walter
