I'm trying to run ffmpeg on a linux server (info from uname -a):
Linux comp32 2.6.32-279.14.1.el6.x86_64 #1 SMP Tue Nov 6 11:21:14 CST 2012 x86_64 x86_64 x86_64 GNU/Linux
ffmpeg (together with the required encoders and decoders) compiles successfully on the system, but when I try to perform a basic operation like the following: ffmpeg -v debug -i example.m4v image%d.jpg, I get a slightly cryptic error message:

I also tried using a static build off ffmpeg, downloaded from here, but got the same resource temporarily unavailable message. Any ideas on how I might be able to fix this?
