I'm trying to start converting videos for my iPhone on my kuro, and I'm getting this funny output from ffmpeg even though the -altivec USE flag is set and ffmpeg thinks it was compiled w/o altivec:

Code:
$ ffmpeg -i [infile].avi -vcodec h264 -acodec aac -s 480x320 -ar 44100 -ab 128 -async 1  -aspect 16:9 -f mp4 -b 1500 -qmin 3 -qmax 5 -bufsize 4096 -g 300 [outfile].mp4

Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (30000/1) -> 23.98 (24000/1001)
Input #0, avi, from '[infile].avi':
  Duration: 01:58:19.9, start: 0.000000, bitrate: 905 kb/s
  Stream #0.0: Video: mpeg4, yuv420p, 640x432, 23.98 fps(r)
  Stream #0.1: Audio: mp3, 44100 Hz, stereo, 128 kb/s
Output #0, mp4, to '[outfile].mp4':
  Stream #0.0: Video: h264, yuv420p, 480x320, q=3-5, 1 kb/s, 23.98 fps(c)
  Stream #0.1: Audio: aac, 44100 Hz, stereo, 0 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
[h264 @ 0xfe5dbe8]using SAR=32/27
[h264 @ 0xfe5dbe8]using cpu capabilities Altivec
Press [q] to stop encoding
Illegal instruction


Any theories on what library is being nasty? (AAC?) Suggestions on how to fix it?
