e07702ba 251 &lt;lists@reserv.at&gt;, but changed completely since we use a format
de6d9b64
FB
252 instead of a protocol).
253
254version 0.4.2:
255
256- added H263/MPEG4/MSMPEG4 decoding support. MPEG4 decoding support
257 (for openDIVX) is almost complete: 8x8 MVs and rounding are
258 missing. MSMPEG4 support is complete.
259- added prototype MPEG1 decoder. Only I and P frames handled yet (it
260 can decode ffmpeg mpegs :-)).
261- added libavcodec API documentation (see apiexample.c).
262- fixed image polyphase bug (the bottom of some images could be
263 greenish).
264- added support for non clipped motion vectors (decoding only)
265 and image sizes non multiple of 16.
266- added support for AC prediction (decoding only).

272- added MSMPEG4 (aka DIVX) compatible encoder. Changed default codec
273 of avi and asf to DIV3.
274- added -me option to set motion estimation method
275 (default=log). suppressed redundant -hq option.
276- added options -acodec and -vcodec to force a given codec (useful for
277 AVI for example).
278- fixed -an option.
279- improved dct_quantize speed.
280- factorized some motion estimation code.
281
282version 0.4.0:

285 stream support to ffmpeg.
286- added timeshifting support for live feeds (option ?date=xxx in the
287 URL).
288- added high quality image resize code with polyphase filter (need
289 mmx/see optimisation). Enable multiple image size support in ffserver.
290- added multi live feed support in ffserver.
291- suppressed master feature from ffserver (it should be done with an
292 external program which opens the .ffm url and writes it to another
293 ffserver).
294- added preliminary support for video stream parsing (wav and avi half
295 done). Added proper support for audio/video file convertion in
296 ffmpeg.
297- added preliminary support for video file sending from ffserver.
298- redesigning I/O subsystem : now using URL based input and output
299 (see avio.h).
