[FFmpeg-user] error attempting 2 pass encoding using libx264

[Nathan Lewis]

I've run into an issue using the most recent ffmpeg version from git.  I'm
attempting to do 2 pass encoding but I get a failure on -pass 1 (see
below).  The strange thing is that the exact same command executes fine
using ffmpeg 1.0.3 build I have on a different machine (see further below).

Any thoughts?
