113 play them (only tested video).
114- fixed h263 white bug.
115- fixed phase rounding in img resample filter.

120 decoder).
121- added fractional frame rate support.
122- codecs are no longer searched by read_header() (should fix ffserver
123 segfault).
124
125version 0.4.3:
126
e07702ba 127- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq@amsat.org>).

136this +codec ;) (JuanJo).
137- Halfpel motion estimation after mb type selection (JuanJo).
138- added pgm and .Y.U.V output format.
139- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or

e07702ba 142 <lists@reserv.at>, but changed completely since we use a format
de6d9b64
FB
143 instead of a protocol).
144
145version 0.4.2:
146
147- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
148 (for openDIVX) is almost complete: 8x8 MVs and rounding are
149 missing. MSMPEG4 support is complete.

151 can decode ffmpeg mpegs :-)).
152- added libavcodec API documentation (see apiexample.c).
153- fixed image polyphase bug (the bottom of some images could be
154 greenish).

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

164 of avi and asf to DIV3.
165- added -me option to set motion estimation method
166 (default=log). suppressed redundant -hq option.

168 AVI for example).
169- fixed -an option.
170- improved dct_quantize speed.
171- factorized some motion estimation code.
172

176 stream support to ffmpeg.
177- added timeshifting support for live feeds (option ?date=xxx in the
178 URL).

180 mmx/see optimisation). Enable multiple image size support in ffserver.
181- added multi live feed support in ffserver.
182- suppressed master feature from ffserver (it should be done with an
183 external program which opens the .ffm url and writes it to another
184 ffserver).
185- added preliminary support for video stream parsing (wav and avi half
186 done). Added proper support for audio/video file convertion in
187 ffmpeg.
188- added preliminary support for video file sending from ffserver.
189- redesigning I/O subsystem : now using URL based input and output
190 (see avio.h).
