140
141version 0.4.3:
142

e07702ba 158 <lists@reserv.at>, but changed completely since we use a format
de6d9b64
FB
159 instead of a protocol).
160

167 can decode ffmpeg mpegs :-)).
168- added libavcodec API documentation (see apiexample.c).

180 of avi and asf to DIV3.
181- added -me option to set motion estimation method
182 (default=log). suppressed redundant -hq option.

186- improved dct_quantize speed.
187- factorized some motion estimation code.
188

196 mmx/see optimisation). Enable multiple image size support in ffserver.
197- added multi live feed support in ffserver.
198- suppressed master feature from ffserver (it should be done with an
199 external program which opens the .ffm url and writes it to another
200 ffserver).
201- added preliminary support for video stream parsing (wav and avi half
202 done). Added proper support for audio/video file convertion in
203 ffmpeg.
204- added preliminary support for video file sending from ffserver.
