From 77d43bf42d76a1a3ccd8ea25937664c7f9d4bcac Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Fri, 15 Jun 2012 19:58:11 +0200 Subject: [PATCH] lavf: don't segfault when a NULL filename is passed to avformat_open_input() This can easily happen when the caller is using a custom AVIOContext. Behave as if the filename was an empty string in this case.
