338 dd5cf2ad Benoit Fouet
- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
339 e0db8cfb Diego Biurrun
- fixed raw yuv output
340
- added motion rounding support in MPEG-4
341
- fixed motion bug rounding in MSMPEG4
342
- added B-frame handling in video core
343
- added full MPEG-1 decoding support
344
- added partial (frame only) MPEG-2 support
345 de6d9b64 Fabrice Bellard
- changed the FOURCC code for H.263 to "U263" to be able to see the
346 e0db8cfb Diego Biurrun
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
347
  this +codec ;) (JuanJo).
348
- Halfpel motion estimation after MB type selection (JuanJo)
349
- added pgm and .Y.U.V output format
350 de6d9b64 Fabrice Bellard
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
351
  output.
352
- added pgmpipe I/O format (original patch from Martin Aumueller
353 dd5cf2ad Benoit Fouet
  <lists at reserv.at>, but changed completely since we use a format
354 e0db8cfb Diego Biurrun
  instead of a protocol)

356
version 0.4.2:
357
358 e0db8cfb Diego Biurrun
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
359
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
360 de6d9b64 Fabrice Bellard
  missing. MSMPEG4 support is complete.
361 e0db8cfb Diego Biurrun
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
362
  can decode ffmpeg MPEGs :-)).
363 de6d9b64 Fabrice Bellard
- added libavcodec API documentation (see apiexample.c).
364
- fixed image polyphase bug (the bottom of some images could be
365 e0db8cfb Diego Biurrun
  greenish)
366 de6d9b64 Fabrice Bellard
- added support for non clipped motion vectors (decoding only)
367 e0db8cfb Diego Biurrun
  and image sizes non-multiple of 16
368
- added support for AC prediction (decoding only)
369
- added file overwrite confirmation (can be disabled with -y)
370
- added custom size picture to H.263 using H.263+ (Juanjo)
371 de6d9b64 Fabrice Bellard
372
version 0.4.1:
373
374 e0db8cfb Diego Biurrun
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
375
  of AVI and ASF to DIV3.
376 de6d9b64 Fabrice Bellard
- added -me option to set motion estimation method
377
  (default=log). suppressed redundant -hq option.
378
- added options -acodec and -vcodec to force a given codec (useful for
379 e0db8cfb Diego Biurrun
  AVI for example)
380
- fixed -an option
381
- improved dct_quantize speed
382
- factorized some motion estimation code
383 de6d9b64 Fabrice Bellard
384
version 0.4.0:
385
386 e0db8cfb Diego Biurrun
- removing grab code from ffserver and moved it to ffmpeg. Added
387
  multistream support to ffmpeg.
388 de6d9b64 Fabrice Bellard
- added timeshifting support for live feeds (option ?date=xxx in the
389 e0db8cfb Diego Biurrun
  URL)
390 de6d9b64 Fabrice Bellard
- added high quality image resize code with polyphase filter (need
391 56cc85a0 Diego Biurrun
  mmx/see optimization). Enable multiple image size support in ffserver.
392 e0db8cfb Diego Biurrun
- added multi live feed support in ffserver
393 de6d9b64 Fabrice Bellard
- suppressed master feature from ffserver (it should be done with an
394
  external program which opens the .ffm url and writes it to another
395 e0db8cfb Diego Biurrun
  ffserver)
396
- added preliminary support for video stream parsing (WAV and AVI half
397
  done). Added proper support for audio/video file conversion in
398 de6d9b64 Fabrice Bellard
  ffmpeg.
399 e0db8cfb Diego Biurrun
- added preliminary support for video file sending from ffserver
400
- redesigning I/O subsystem: now using URL based input and output
401
  (see avio.h)
402
- added WAV format support
403
- added "tty user interface" to ffmpeg to stop grabbing gracefully
404
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)

406 e0db8cfb Diego Biurrun
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
407
- added new motion estimation algorithms, log and phods (Juanjo)

  bitrates and large GOP size
