Thanks. I have uploaded the clip there as cmarrin_sample.mov. If you  
run:

     ffmpeg -i cmarrin_sample.mov foo.mp4

You will get this output:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'cmarrin_sample.mov':
   Duration: 00:00:03.66, start: 0.000000, bitrate: 15248 kb/s

Cannot get resampling context

I would open a bug, but roundup times out when I try to register. Let  
me know if I can provide any more info
