c2d23309 194- Flash Screen Video 2 decoder
4d58e4cb 195- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
196- ffmpeg deprecated, added avconv, which is almost the same for now, except
197for a few incompatible changes in the options, which will hopefully make them
198easier to use. The changes are:
199 * The options placement is now strictly enforced! While in theory the
200 options for ffmpeg should be given in [input options] -i INPUT [output
201 options] OUTPUT order, in practice it was possible to give output options
202 before the -i and it mostly worked. Except when it didn't - the behavior was
203 a bit inconsistent. In avconv, it is not possible to mix input and output
204 options. All non-global options are reset after an input or output filename.
205 * All per-file options are now truly per-file - they apply only to the next
206 input or output file and specifying different values for different files
207 will now work properly (notably -ss and -t options).
208 * All per-stream options are now truly per-stream - it is possible to
209 specify which stream(s) should a given option apply to. See the Stream
210 specifiers section in the avconv manual for details.
211 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
212 sense that they're specified after the output filename instead of before,
213 like all other options. In avconv this irregularity is removed, all options
214 apply to the next input or output file.
215 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
216 irregular and highly confusing, they were also redundant. In avconv the -map
217 option will create new streams in the output file and map input streams to
218 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
219 each stream in the first input file.
220 * The -map option now has slightly different and more powerful syntax:
221 + Colons (':') are used to separate file index/stream type/stream index
222 instead of dots. Comma (',') is used to separate the sync stream instead
223 of colon.. This is done for consistency with other options.
224 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
225 output stream from the third input audio stream.
226 + Omitting the stream index now maps all the streams of the given type,
227 not just the first. E.g. -map 0:s creates output streams for all the
228 subtitle streams in the first input file.
229 + Since -map can now match multiple streams, negative mappings were
320d7693 230 introduced. Negative mappings disable some streams from an already
231 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
232 all the stream in the first input file, except for the second audio
233 stream'.
234 * There is a new option -c (or -codec) for choosing the decoder/encoder to
235 use, which allows to precisely specify target stream(s) consistently with
236 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
237 libvorbis sets the codec for the first audio stream and -c copy copies all
238 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
239 aliases to -c:v/a/s
320d7693 240 * It is now possible to precisely specify which stream should an AVOption
241 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
242 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
243 syntax is deprecated and will stop working soon.
244 * -map_chapters now takes only an input file index and applies to the next
245 output file. This is consistent with how all the other options work.
246 * -map_metadata now takes only an input metadata specifier and applies to
247 the next output file. Output metadata specifier is now part of the option
248 name, similarly to the AVOptions/map/codec feature above.
249 * -metadata can now be used to set metadata on streams and chapters, e.g.
250 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
251 This made -vlang/-alang/-slang options redundant, so they were removed.
252 * -qscale option now uses stream specifiers and applies to all streams, not
253 just video. I.e. plain -qscale number would now apply to all streams. To get
254 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
255 and -aq is now an alias for -q:a.
256 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
257 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
258 * -itsscale option now uses stream specifiers, so its argument is only the
259 scale parameter.
260 * -intra option was removed, use -g 0 for the same effect.
261 * -psnr option was removed, use -flags +psnr for the same effect.
262 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
263 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
264 * -vtag/-atag/-stag options are now aliases to the new -tag option.

869 play them (only tested video)
870- fixed H.263 white bug
871- fixed phase rounding in img resample filter
872- add MMX code for polyphase img resample filter

877 decoder)
878- added fractional frame rate support
de6d9b64 879- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 880 segfault)

883version 0.4.3:
dd5cf2ad 885- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)

891- added partial (frame only) MPEG-2 support
de6d9b64 892- changed the FOURCC code for H.263 to "U263" to be able to see the
893 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
894 this +codec ;) (JuanJo).
895- Halfpel motion estimation after MB type selection (JuanJo)
896- added pgm and .Y.U.V output format
897- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
898 output.
899- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 900 <lists at>, but changed completely since we use a format
e0db8cfb 901 instead of a protocol)
de6d9b64 902
0ca3e336 903
904version 0.4.2:
906- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
907 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 908 missing. MSMPEG4 support is complete.
909- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
910 can decode ffmpeg MPEGs :-)).
911- added libavcodec API documentation (see apiexample.c).
912- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 913 greenish)
de6d9b64 914- added support for non clipped motion vectors (decoding only)
915 and image sizes non-multiple of 16
916- added support for AC prediction (decoding only)
917- added file overwrite confirmation (can be disabled with -y)
918- added custom size picture to H.263 using H.263+ (Juanjo)

921version 0.4.1:
923- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
924 of AVI and ASF to DIV3.
925- added -me option to set motion estimation method
926 (default=log). suppressed redundant -hq option.
927- added options -acodec and -vcodec to force a given codec (useful for
928 AVI for example)
929- fixed -an option
930- improved dct_quantize speed
931- factorized some motion estimation code

e0db8cfb 939 URL)
de6d9b64 940- added high quality image resize code with polyphase filter (need
56cc85a0 941 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 942- added multi live feed support in ffserver
943- suppressed master feature from ffserver (it should be done with an
944 external program which opens the .ffm url and writes it to another
945 ffserver)
946- added preliminary support for video stream parsing (WAV and AVI half
947 done). Added proper support for audio/video file conversion in
de6d9b64 948 ffmpeg.
949- added preliminary support for video file sending from ffserver
950- redesigning I/O subsystem: now using URL based input and output
951 (see avio.h)
