Yes, I have the same problem. I have tested versions 0.24 and 0.25.

Please see thread "[theora] Accelerated video output with ffmpeg2theora 0.24" in the archives of this mailing list.

I have an AVI container with this stream:

    Stream #0.0: Video: rawvideo, yuyv422, 720x576, 25.02 tbr, 25.02 tbn, 25.02 tbc

Regards, JJ
