I have a fairly old build of ffmpeg -

FFmpeg version SVN-r24841, Copyright (c) 2000-2010 the FFmpeg developers
  built on Aug 19 2010 16:20:28 with gcc 4.1.2 20080704 (Red Hat 4.1.2-48)

With the following command line, it processes this particular MP4 file acceptably fast (about 90 seconds)

 /usr/local/bin/ffmpeg -i 2423.mp4 -s 480x352 -vcodec libx264 -acodec libfaac -vpre fast -b 300k -bt 300k -threads 0 2423.mp4.mp4

The last line from ffmpeg is:
frame= 5235 fps= 64 q=-1.0 Lsize=    7171kB time=175.40 bitrate= 334.9kbits/s    


I built ffmpeg from the latest tarball today and something has happened so that it runs incredibly slowly and eventually gives up.

/usr/local/bin/ffmpeg -loglevel quiet -v 0 -i /tmp/videoproc-11865/2423.mp4 -s 480x352 -an -pass 1 -vcodec libx264 -vpre fast_firstpass -b 300k -bt 300k -threads 0 /tmp/videoproc-11865/2423.mp4.mp4

Seems stream 1 codec frame rate differs from container frame rate: 60000.00 (60000/1) -> 30000.00 (60000/2)
Stream mapping:
   Stream #0.1 -> #0.0
