Netbeans was pointing me to the wrong header file. I got the latest
version to build, but when I run the example video decoder in the docs
directory I get this error:
[mpeg1video @ 0x16b4ce0] mpeg_decode_postinit() failure
Error while decoding frame 0
Any ideas what that means? I googled for it, but didn't find an answer.
