 Saved a wmv movie from a website, want to use it as h.264 mp4 file.
 Regardless of commandline options (-analyzeduration included), I am not
 able to convert.  Leaving off the output file, all output looks good until
 it says it needs at least one output file to proceed.  Once that is given,
 message "swScaler: Unknown format is not supported as input pixel format -
 Cannot get resampling context" is given.  Tried outputting to different
 formats, all same result.  Running on Red Hat 5.4 64-bit server as root
 and even chmod 777'd the input file, no change.  Running ffmpeg 0.6.5.
 Tried yum install *ffmpeg* and yum update *ffmpeg* to make sure I had all
 dependencies at the latest rev. Same message every time.  Output below,
 input video attached.  For the record, the input videos plays perfectly on
 every media player I've tried.

 "ffmpeg -v 9 -loglevel 99 -i" output:
