[Theora-dev] ffmpeg2theora conveter problem

[steve]

Hi:

I am trying to convert an avi file to an ogg file. 

The avi file is 12 frames /sec, resolution 1280x768, 24bits, compression: Cinepak Codec.
I got the following message.

D:\Dragon\Tools\Theora>ffmpeg2theora-0.16.exe -V 16000 Astro.avi
Input #0, avi, from 'Astro.avi':
  Duration: 00:00:04.0, start: 0.000000, bitrate: 19604 kb/s
  Stream #0.0, 12.00 fps(r): Video: cinepak, yuv420p, 1280x768
  Stream #0.1: Audio: pcm_s16le, 44100 Hz, stereo, 1411 kb/s
  Resize: 1280x768
      0:00:04.00 audio: 45kbps video: 1kbps

The audio in the ogg file is fine, but I got a blank image.
I have to reduce the resolution to 1024x768 to make the image correct. 
It seems that the limit of the bit rate is too small.

Can any body tell me how to make large resolution ogg file.

Thank you.

Steve
