Summary of the bug:
Source specific multicast input works on Linux and Windows, but not on
OSX.
I have two hosts streaming an MPEG2 transport stream to the same multicast
IP address and port. In my test setup the IP address of the sources are
10.66.133.33 and 10.66.133.34 they are both streaming to
239.36.34.100:4900. I can tune into the desired stream by selecting the
sources as follows:
{{{
ffplay 'udp://@239.36.34.100:4900?sources=10.66.133.34'
}}}
This works on Linux and Windows but does not work on OSX with the
following error:
{{{
setsockopt(MCAST_JOIN_SOURCE_GROUP): Can't assign requested address
udp://@239.36.34.100:4900?sources=10.66.133.34: Input/output error
}}}
NOTE: SSM does work correctly on VLC on OSX. The VLC syntax is slightly
different:
{{{
/Applications/VLC.app/Contents/MacOS/VLC
'udp://[email protected]:4900'
}}}
