[FFmpeg-devel] UDP multicasts mixed up on receive due to wrong bind()

[Jindrich Makovicka]

Hi,

current SVN ffmpeg mixes up two different multicasts with the same
port at the input. For example, when we have two different MPEG-TS
multicast channels, trying

./ffplay -an udp://239.194.10.11:1234 &

./ffplay -an udp://239.194.10.12:1234 &

causes the second command play randomly one of the two multicasts,
depending on whose SDT/PAT arrives first.

Supplying the multicast address to bind() as in the patch fixes the
issue.

Regards,
