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://@239.36.34.100:4900?sources=10.66.133.34' -codec copy -f
crc crc.txt
ffmpeg -i 'udp://@239.36.34.100:4900' -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
reception.
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.
