FFmpeg is in a state of perpetual development and we do not currently have the person power to backport fixes to official releases. As such, if you wish to query or report a bug, you must try with the latest development branch revision of FFmpeg to confirm the issue still exists. The latest FFmpeg can be downloaded from here: http://www.ffmpeg.org/download.html
ffmpeg -codecs gives only libvpx for VP8 encoding, so my first guess is there is no support (currently) for VP6 But, did you try searching on the mailing list? For example here: http://ffmpeg.org/pipermail/ffmpeg-user ... 04673.html
