 {{{
 ffmpeg: tls: server name not specified
 }}}

 The error is caused by no server name being specified, yet verification is
 enabled. With a numeric host it passes NULL as the server name to
 tls_connect_cbs(), which will cause the "server name not specified"
 failure.

 https://github.com/FFmpeg/FFmpeg/blob/acdea9e7c56b74b05c56b4733acc855b959ba073/libavformat/tls_libtls.c#L121

 We should probably disable at least name verification for numeric hosts.
