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

146 play them (only tested video).
147- fixed h263 white bug.
148- fixed phase rounding in img resample filter.

153 decoder).

155- codecs are no longer searched by read_header() (should fix ffserver
156 segfault).
157
158version 0.4.3:
159
e07702ba 160- BGR24 patch (initial patch by Jeroen Vreeken &lt;pe1rxq@amsat.org&gt;).

169this +codec ;) (JuanJo).
170- Halfpel motion estimation after mb type selection (JuanJo).
171- added pgm and .Y.U.V output format.
172- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
173 output.

e07702ba 175 &lt;lists@reserv.at&gt;, but changed completely since we use a format
de6d9b64
FB
176 instead of a protocol).
177
178version 0.4.2:
179
180- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
181 (for openDIVX) is almost complete: 8x8 MVs and rounding are

184 can decode ffmpeg mpegs :-)).
185- added libavcodec API documentation (see apiexample.c).
186- fixed image polyphase bug (the bottom of some images could be
187 greenish).

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

196- added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec
197 of avi and asf to DIV3.
198- added -me option to set motion estimation method
199 (default=log). suppressed redundant -hq option.

201 AVI for example).
202- fixed -an option.
203- improved dct_quantize speed.
204- factorized some motion estimation code.
205
206version 0.4.0:

209 stream support to ffmpeg.
210- added timeshifting support for live feeds (option ?date=xxx in the
211 URL).

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