[FFmpeg-devel] [patch] fix problem receiving udp multicast

[Ed Torbett]

Full RFC4570 support was added early august. The lack of binding is not what's stopping decoding, as udp.c contains code to filter based on source address outside of the binding.

If you're not using SDP files, make sure you use the ?sources= parameter to set the multicast source addresses. If you are using SDP files then as stated in RFC4570 you should be using the source-filter attribute to specify the source address.
