244 &lt;lists@reserv.at&gt;, but changed completely since we use a format
245 instead of a protocol).
246

256 greenish).

266 of avi and asf to DIV3.
267 - added -me option to set motion estimation method
268 (default=log). suppressed redundant -hq option.

272 - improved dct_quantize speed.
273 - factorized some motion estimation code.
274

278 stream support to ffmpeg.
279 - added timeshifting support for live feeds (option ?date=xxx in the
280 URL).

282 mmx/see optimisation). Enable multiple image size support in ffserver.
283 - added multi live feed support in ffserver.
284 - suppressed master feature from ffserver (it should be done with an
285 external program which opens the .ffm url and writes it to another
286 ffserver).
287 - added preliminary support for video stream parsing (wav and avi half
288 done). Added proper support for audio/video file convertion in
289 ffmpeg.
290 - added preliminary support for video file sending from ffserver.
291 - redesigning I/O subsystem : now using URL based input and output
292 (see avio.h).

294 - added "tty user interface" to ffmpeg to stop grabbing gracefully.
295 - added MMX/SSE optimizations to SAD (Sums of Absolutes Diferences)
296 (Juan J. Sierralta P. a.k.a. "Juanjo" &lt;juanjo@atmlab.utfsm.cl&gt;).
297 - added MMX DCT from mpeg2_movie 1.5 (Juanjo).
298 - added new motion estimation algorithms, log and phods (Juanjo).
