174 &lt;lists@reserv.at&gt;, but changed completely since we use a format
175 instead of a protocol).
176

196 of avi and asf to DIV3.
197 - added -me option to set motion estimation method
198 (default=log). suppressed redundant -hq option.

202 - improved dct_quantize speed.
203 - factorized some motion estimation code.
204

212 mmx/see optimisation). Enable multiple image size support in ffserver.
213 - added multi live feed support in ffserver.
214 - suppressed master feature from ffserver (it should be done with an
215 external program which opens the .ffm url and writes it to another
216 ffserver).
217 - added preliminary support for video stream parsing (wav and avi half
218 done). Added proper support for audio/video file convertion in
219 ffmpeg.
220 - added preliminary support for video file sending from ffserver.
221 - redesigning I/O subsystem : now using URL based input and output
222 (see avio.h).
