From c5c4ca6bc88135f5e819dd707fee68a01c9ffe08 Mon Sep 17 00:00:00 2001 From: Florian Jacob Date: Wed, 11 Mar 2015 01:13:44 +0100 Subject: [PATCH] lavf/libssh: support reading config from ~/.ssh/config libssh provides a function for parsing ~/.ssh/config for ssh connection parameters like user, hostname, identity file and port. This patch makes ffmpeg use this function to take parameters from the config file for everything that's not explicitely set in the url. It also supports host aliases, i.e. using a shorthand in the url and replacing it with the hostname / IP address specified for the shorthand in the config file.
