* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-1/+1
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-201-0/+2
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.

* avformat/udp: cancel pending IO on win32 manuallyMarton Balint2020-02-021-1/+10
| | | | | | | | | | | | | recvfrom() is not a cancellation point in pthreads-win32, see https://sourceware.org/pthreads-win32/manual/pthread_cancel.html In order to be able to cancel the reader thread on Win32 properly we first shutdown the socket then call CancelIoEx to abort pending IO. Subsequent recvfrom() calls will fail with WSAESHUTDOWN causing the thread to exit. Fixes ticket #5717. Signed-off-by: Marton Balint <cus@passwd.hu>

* avformat/udp: increase the default buffer size of a receiving socket to 384KMarton Balint2020-01-251-1/+2
| | | | | | | | | | | | It is a common mistake that people only increase fifo_size when they experience drops, unfortunately this does not help for higher bitrate (> 100 Mbps) streams when the reader thread simply might not receive the packets in time (especially under high CPU load) if the default 64 KB of kernel buffer size is used. New default is determined so that common linux systems can set this buffer size without tuning kernel parameters. Signed-off-by: Marton Balint <cus@passwd.hu>

* avformat/udp: always use IP_ADD_SOURCE_MEMBERSHIP for subscribing to an UDP ↵Marton Balint2018-10-031-24/+28
| | | | | | | | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/udp: specify the local address for some source filtered multicast joinsMarton Balint2018-10-031-4/+11
| | | | | | | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/udp: add support for generic source filteringMarton Balint2018-10-031-4/+13
| | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>

* lavf/udp: fix dead code.Nicolas George2016-06-031-1/+1
| | | | | | | | | | Since d607861, service can not be NULL, only "0". An UDP address with neither local port nor address leaves both service and node to their default value, and POSIX specifies that they are not allowed to be both NULL; "0" is equivalent to an unspecified port for all currently known protocols. Fix CID 1341570.
