HTML5 Video OGV conversion on Mac

When I try recording a screencast with Quicktime or Screenflow and then converting to .ogv for use on the web, I get this error many times:

$ ffmpeg2theora test.mov
[audioresample @ 0x7fa903800ee0] Audio sample format conversion failed

The resulting test.ogv file does not play in VLC. I can use ffmpeg to successfully convert mov to mp4. Are there only certain audio types that ffmpeg2theora supports? ffmpeg2theora version 0.29

More output:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mov':
