avconv throwing errors while converting mov to ogg

I am getting the following error constantly while trying to convert mov file to ogg using avconv and ffmpeg. I am completely unable to understand the verbose messages displayed below.

I looked at similar threads, but could not make out anything from it. Does anyone have any ideas?

edit:

I actually got it to work...but now cannot get an FPS of more than 8 for some reason.

the command that worked was

avconv -i IMG_0243.mp4 -acodec libvorbis -f ogg -r 24.01 IMG_0243.ogv -ac 2 -ar 44100 -b 64k -s 1920x1080

If you are talking about the fps printed on the screen that is just the rate of encoding. It has nothing to do with the fps of the file that will be created. Encoding a 1080p requires high end hardware and fast encoders. While you may have the hardware libtheora is not optimized like other encoders. So it will be slow.
