Convert HTML5 OGV Video to Mac

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

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

The resulting test.ogv file test.ogv not play in the VLC. I can use ffmpeg to successfully convert mov to mp4. Are there only certain types of audio supported by ffmpeg2theora ? Ffmpeg2theora version 0.29

More output:

You may be especially interested in ffmpeg solution, but Miro Video Convertor is another free OS X option that works great for converting mov to ogg.
