Comment (by Berbe):
If I ran the minimal command, the same encoders are used:
{{{
ffmpeg -y -i 2012-11-23_21-02-59.avi 2012-11-23_21-02-59.webm
}}}
The only other vorbis encoder is 'vorbis', which is experimental and which
I can't make work.
If I select the video stream only, the video is encoded without any touble
so the problem comes from the 'libvorbis' audio encoder indeed:
{{{
% ffmpeg -y -i 2012-11-23_21-02-59.avi -map 0:v 2012-11-23_21-02-59.webm

I tried to reproduce the problem with a video converted to mjpeg/pcm_u8
with the same parameters as those from genuine MJPEG videos I was trying
to convert (8000Hz mono).
The problem doesn't seem to appear when converting those crafted MJPEG
videos sound to Vorbis.
I can't provide you directly with a sample of the videos I'm working on
for privacy reasons.
I'll try to provide you with a sample from the camera later.
