[Libav-user] mpeg_decode_postinit() failure

[Bob Self]

I built the current version of ffmpeg and ran the video_decode example
that came with it.
codec version = 54.10.100
I tried the program on 3 different videos and I get this error

Video decoding
[mpeg1video @ 0x330bce0] mpeg_decode_postinit() failure
Error while decoding frame 0

I built ffmpeg with all the default settings. The videos are on my
local hard drive.

Why does this error happen?
