From d0e9415d234f701bed8837f4e315131ea4e84482 Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Wed, 6 Jun 2012 17:12:29 +0100 Subject: fate: avoid freopen(NULL) in videogen/rotozoom A number of systems do not implement freopen() with a NULL filename correctly. This changes these programs to output individual images if opening a named output argument as a file fails, in this case assuming it is a directory.
