r><br>Personnaly I use OGG Theora for all my videos.<br>I have a little example page \
where I upload a video encoded at 256kbps max (both audio and video) \
here:<br>http://home.tele2.fr/crossover/<br><br>I use a fifo with mplayer to provide \
the content to encoder_example.<br>The video is encoded at 15fps, transcoded with \
mencoder to get this framerate.<br><br>For the audio I use a mono channel at 22050Hz \
and encoded with the -1 setting.<br><br>Every time I reset the settings to be at \
256kbps so I do not have fixed settings, it depends of the video material. The audio \
is almost always at 24kbps.<br><br>I even have a good example at 128kbps here: \
http://gameclash.org/breve.php3?id_breve=53<br>It is quite rare to reach such a low \
bitrate with a good quality.<br><br>Best \
