144 decoder).

148
149version 0.4.3:
150

e07702ba 166 &lt;lists@reserv.at&gt;, but changed completely since we use a format
de6d9b64
FB
167 instead of a protocol).
168

175 can decode ffmpeg mpegs :-)).
176- added libavcodec API documentation (see apiexample.c).
177- fixed image polyphase bug (the bottom of some images could be
178 greenish).

188 of avi and asf to DIV3.
189- added -me option to set motion estimation method
190 (default=log). suppressed redundant -hq option.

192 AVI for example).
193- fixed -an option.
194- improved dct_quantize speed.
195- factorized some motion estimation code.
196

200 stream support to ffmpeg.
201- added timeshifting support for live feeds (option ?date=xxx in the
202 URL).

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