I've actually cleaned this up a bit while trying to implement DTLS via
schannel, and effectively removed the whole section:
https://github.com/BtbN/FFmpeg/commit/b6794f1373fb07b791cfacd2189c7efc4d6bdbcc
There's also a bunch of other necessary UDP related fixes in tls.c.
Don't try to use an http proxy for UDP. It doesn't work:
https://github.com/BtbN/FFmpeg/commit/709ce9e5c48e3a27a400cf5af35038d3f0602c8a
I totally agree with the above two patches, it’s very reasonable
Properly forward the various hosts and ports to udp.c so it actually works when
using a non-external UDP connection:
https://github.com/BtbN/FFmpeg/commit/46375adf7d9cc61f709ab14dd2ea017995f735db
But I think this patch need a bit modify, I think the c->listen stands for
FFmpeg if is server. When it is true, FFmpeg as server.
So maybe:
if (c->listen) {
av_dict_set_int(options, "localport", port, 0);
av_dict_set(options, "localaddr", c->underlying_host, 0);Add

} else {
av_dict_set_int(options, "connect", 1, 0);
}
Sry for forgetting modify this code, the right code I want to express is that:
if (c->listen) {
av_dict_set_int(options, "connect", 1, 0);
} else {
av_dict_set_int(options, "localport", port, 0);
av_dict_set(options, "localaddr", c->underlying_host, 0);
}
It goes together with
https://github.com/BtbN/FFmpeg/commit/6fc902eb75554e6ad91a2ddf4ce1d131feee6f55
Without setting the localport to 0 in client-mode in combination with
above patch, it'll try to bind to the port passed in the URL, which when
tryong to connect to a server on localhost will result in a bind
failure, cause it tried to bind to the same port.
And "connect" in listen mode makes no sense to me?
There is no remote address, where would it "connect" the socket to?
