* lavf/udp: Do not use MCAST_* for multicast on tvOS.Carl Eugen Hoyos2016-09-03
| | | | Fixes ticket #5774.
* avformat/udp: replace packet_gap with bitrate optionMarton Balint2016-06-19
| | | | | | | | We haven't had a stable release since the packet_gap addition, so probably it is worth reworking the option to something that makes more sense to the end user. Also add burst_bits option to specify maximum length of bit bursts. Signed-off-by: Marton Balint <cus@passwd.hu>

* lavf/udp: fix dead code.Nicolas George2016-06-03
| | | | | | | | | | 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.

* avformat/udp: Add a delay between packets for streaming to clients with ↵Pavel Nikiforov2016-05-25
| | | | | | | | | | | | | | | | short buffer This commit enables sending UDP packets in a background thread with specified delay. When sending packets without a delay some devices with small RX buffer ( MAG200 STB, for example) will drop tail packets in bursts causing decoding errors. To use it specify "fifo_size" with "packet_gap" . The output url will looks like udp://xxx:yyy?fifo_size=<output fifo size>&packet_gap=<delay in usecs> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| * lavf: reorganize URLProtocolsAnton Khirnov2016-02-22
| | | | | | | | | | | | | | | | | | | | Instead of a linked list constructed at av_register_all(), store them in a constant array of pointers. Since no registration is necessary now, this removes some global state from lavf. This will also allow the urlprotocol layer caller to limit the available protocols in a simple and flexible way in the following commits.

| | | | | | | | | | | | | | | | | | Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE. The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros. This solution is on the lines of the one in commit af1818276ef271af98e2e2bbabb4dc875b4fa7d8.

* | UDP: join multicast group on the interface specified with &localaddr=Stoian Ivanov2013-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When joining multicast groups, ffmpeg was using INADDR_ANY as interface address which leads to enabling the multicast group on the interface with "default gateway". Often multicast traffic is received over dedicated interface, which scenario ffmpeg was unable to handle. With this patch, ffmpeg will enable multicast group to the interfaces configured with address specified in &localaddr= parameter of udp:// URL. To avoid loacal_addr resolve at udp_close(...) the UDPContext structure was extended with struct sockaddr_storage local_addr_storage member, which is populated in udp_open(..) and passed to udp_join_multicast_group() and udp_leave_multicast_group().
