134- added prototype RM demux.
135- added AC3 decoding (done with libac3 by Aaron Holtzman).

139 play them (only tested video).
140- fixed h263 white bug.
141- fixed phase rounding in img resample filter.

146 decoder).

148- codecs are no longer searched by read_header() (should fix ffserver
149 segfault).
150
151version 0.4.3:
152
e07702ba 153- BGR24 patch (initial patch by Jeroen Vreeken &lt;pe1rxq@amsat.org&gt;).

162this +codec ;) (JuanJo).
163- Halfpel motion estimation after mb type selection (JuanJo).

e07702ba 168 &lt;lists@reserv.at&gt;, but changed completely since we use a format
de6d9b64
FB
169 instead of a protocol).
170
171version 0.4.2:
172
173- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support

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

182 and image sizes non multiple of 16.
183- added support for AC prediction (decoding only).

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

194 AVI for example).
195- fixed -an option.
196- improved dct_quantize speed.
197- factorized some motion estimation code.
198

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

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