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

116 play them (only tested video).
117- fixed h263 white bug.
118- fixed phase rounding in img resample filter.
119- add mmx code for polyphase img resample filter.

123 decoder).
124- added fractional frame rate support.
125- codecs are no longer searched by read_header() (should fix ffserver
126 segfault).
127
128version 0.4.3:
129
e07702ba 130- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq@amsat.org>).

137- changed the FOURCC code for H.263 to "U263" to be able to see the
138+AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
139this +codec ;) (JuanJo).
140- Halfpel motion estimation after mb type selection (JuanJo).
141- added pgm and .Y.U.V output format.
142- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
143 output.
144- added pgmpipe I/O format (original patch from Martin Aumueller
e07702ba 145 <lists@reserv.at>, but changed completely since we use a format
de6d9b64
FB
146 instead of a protocol).
147
148version 0.4.2:
149
150- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
151 (for openDIVX) is almost complete: 8x8 MVs and rounding are
152 missing. MSMPEG4 support is complete.
153- added prototype MPEG1 decoder. Only I and P frames handled yet (it
154 can decode ffmpeg mpegs :-)).
155- added libavcodec API documentation (see apiexample.c).
156- fixed image polyphase bug (the bottom of some images could be
157 greenish).
158- added support for non clipped motion vectors (decoding only)
159 and image sizes non multiple of 16.
160- added support for AC prediction (decoding only).
161- added file overwrite confirmation (can be disabled with -y).

165
166- added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec
167 of avi and asf to DIV3.
168- added -me option to set motion estimation method
169 (default=log). suppressed redundant -hq option.
170- added options -acodec and -vcodec to force a given codec (useful for
171 AVI for example).
172- fixed -an option.
173- improved dct_quantize speed.
174- factorized some motion estimation code.
175
176version 0.4.0:

178- removing grab code from ffserver and moved it to ffmpeg. Added multi
179 stream support to ffmpeg.
180- added timeshifting support for live feeds (option ?date=xxx in the
181 URL).
182- added high quality image resize code with polyphase filter (need
183 mmx/see optimisation). Enable multiple image size support in ffserver.
184- added multi live feed support in ffserver.
185- suppressed master feature from ffserver (it should be done with an
186 external program which opens the .ffm url and writes it to another
187 ffserver).
188- added preliminary support for video stream parsing (wav and avi half
189 done). Added proper support for audio/video file convertion in
190 ffmpeg.
191- added preliminary support for video file sending from ffserver.
192- redesigning I/O subsystem : now using URL based input and output
193 (see avio.h).
