5a3ce4a92b lavfi/deshake: fix deshake crash issue. 
Fixes ticket #7441.

for block contrast calculate, the block is like this:

|<---------------- stride-----------------------|
+----------------------------------------------->  X
|
|            w = 16
|    (cx,cy)+------+
|           |      |
|h=blocksize|      |
|           |      |
|           +------+
V

Y

so we calc the block contrast use:
   (cy + y) * stride + (cx + x)

ab0812c1a8 avformat/udp: always use IP_ADD_SOURCE_MEMBERSHIP for subscribing to an UDP multicast source group in IPv4 
That alone supports specifying the interface based on its address. Getting the
interface index from the local address seems quite a bit of work in a platform
independent way...

Obviously for IPv6 we still always use MCAST_JOIN_SOURCE_GROUP.

As a side effect this also fixes ticket #7459.

d3bda871f0 avformat/udp: specify the local address for some source filtered multicast joins 
We already use localaddr for the multicast joins without source filters, so we
should use them for source filters as well. This patch only fixes the
IP_ADD_SOURCE_MEMBERSHIP and the IP_BLOCK_SOURCE case.

Unless we do this, the kernel automatically selects an interface based on the
source address, and that interface might be different from the one set in
localaddr. For blocked sources this even casues EINVAL because we joined the
multicast group on a different interface.

91a1363452 avformat/udp: add support for generic source filtering 
This allows getting data only from a specific source IP. This is useful not
only for unicast but for multicast as well because multicast source
subscriptions do not act as source filters for the incoming packets.
