Comment (by jlsantiago0):

 @cus I tested your patches. Applied the patches 1-7. I found some
 regression on windows builds and OSX still does not work with SSM.

 I tested as follows with and without SSM:

 ffmpeg -i 'udp://@' -codec copy -f
 crc crc.txt
 ffmpeg -i 'udp://@' -codec copy -f crc crc.txt

 I applied your patches and rebuilt for WIN64, OSX, and Linux:
 1) Linux is working fine.
 2) Windows builds used to work fine in SSM and non SSM modes. With your
 patches it fails on both SSM and non-SSM streams multicast stream
 3) OSX works on non-SSM multicast input, but receives nothing when sources
 is specified.

 Please note that windows builds are no longer able to receive multicast
 streams at all.
