this seems to be a pretty common problem, one we actually addressed in the forums here. The issue is that certain versions of ffmpeg (don't know what version this was changed) need to be fed a k instead of kb when using the -ab flag.

the clue is in the error:

[NULL @ 0x11ce1480] [Eval @ 0x7ffffc05e800] Invalid chars 'b' at the end of expression '128kb'

so the easiest fix is to change the convert me script to remove the b in kb.

so the ffmpeg command should look like this:
/usr/bin/ffmpeg -i /home/transitx/public_html/uploads/VpbSGny0StfEeEeARTWF.flv -acodec libfaac -ab 128k -vcodec mpeg4 -b 1200k -mbd 2 -cmp 2 -subcmp 2 -s 640x480 /home/transitx/public_html/uploads/VpbSGny0StfEeEeARTWF.mp4

I believe this will help you get this working!
