c2d23309 182- Flash Screen Video 2 decoder
4d58e4cb 183- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
184- ffmpeg deprecated, added avconv, which is almost the same for now, except
185for a few incompatible changes in the options, which will hopefully make them
186easier to use. The changes are:
187 * The options placement is now strictly enforced! While in theory the
188 options for ffmpeg should be given in [input options] -i INPUT [output
189 options] OUTPUT order, in practice it was possible to give output options
190 before the -i and it mostly worked. Except when it didn't - the behavior was
191 a bit inconsistent. In avconv, it is not possible to mix input and output
192 options. All non-global options are reset after an input or output filename.
193 * All per-file options are now truly per-file - they apply only to the next
194 input or output file and specifying different values for different files
195 will now work properly (notably -ss and -t options).
196 * All per-stream options are now truly per-stream - it is possible to
197 specify which stream(s) should a given option apply to. See the Stream
198 specifiers section in the avconv manual for details.
199 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
200 sense that they're specified after the output filename instead of before,
201 like all other options. In avconv this irregularity is removed, all options
202 apply to the next input or output file.
203 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
204 irregular and highly confusing, they were also redundant. In avconv the -map
205 option will create new streams in the output file and map input streams to
206 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
207 each stream in the first input file.
208 * The -map option now has slightly different and more powerful syntax:
209 + Colons (':') are used to separate file index/stream type/stream index
210 instead of dots. Comma (',') is used to separate the sync stream instead
211 of colon.. This is done for consistency with other options.
212 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
213 output stream from the third input audio stream.
214 + Omitting the stream index now maps all the streams of the given type,
215 not just the first. E.g. -map 0:s creates output streams for all the
216 subtitle streams in the first input file.
217 + Since -map can now match multiple streams, negative mappings were
320d7693 218 introduced. Negative mappings disable some streams from an already
219 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
220 all the stream in the first input file, except for the second audio
221 stream'.
222 * There is a new option -c (or -codec) for choosing the decoder/encoder to
223 use, which allows to precisely specify target stream(s) consistently with
224 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
225 libvorbis sets the codec for the first audio stream and -c copy copies all
226 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
227 aliases to -c:v/a/s
320d7693 228 * It is now possible to precisely specify which stream should an AVOption
229 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
230 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
231 syntax is deprecated and will stop working soon.
232 * -map_chapters now takes only an input file index and applies to the next
233 output file. This is consistent with how all the other options work.
234 * -map_metadata now takes only an input metadata specifier and applies to
235 the next output file. Output metadata specifier is now part of the option
236 name, similarly to the AVOptions/map/codec feature above.
237 * -metadata can now be used to set metadata on streams and chapters, e.g.
238 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
239 This made -vlang/-alang/-slang options redundant, so they were removed.
240 * -qscale option now uses stream specifiers and applies to all streams, not
241 just video. I.e. plain -qscale number would now apply to all streams. To get
242 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
243 and -aq is now an alias for -q:a.
244 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
245 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
246 * -itsscale option now uses stream specifiers, so its argument is only the
247 scale parameter.
248 * -intra option was removed, use -g 0 for the same effect.
249 * -psnr option was removed, use -flags +psnr for the same effect.
250 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
251 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
252 * -vtag/-atag/-stag options are now aliases to the new -tag option.

852- added prototype RM demuxer
853- added AC3 decoding (done with libac3 by Aaron Holtzman)
854- added decoding codec parameter guessing (.e.g. for MPEG, because the

856- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
857 play them (only tested video)
858- fixed H.263 white bug
859- fixed phase rounding in img resample filter
860- add MMX code for polyphase img resample filter

865 decoder)
866- added fractional frame rate support
de6d9b64 867- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 868 segfault)

871version 0.4.3:
dd5cf2ad 873- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)

879- added partial (frame only) MPEG-2 support
de6d9b64 880- changed the FOURCC code for H.263 to "U263" to be able to see the
881 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
882 this +codec ;) (JuanJo).
883- Halfpel motion estimation after MB type selection (JuanJo)
884- added pgm and .Y.U.V output format
885- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
886 output.
887- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 888 <lists at>, but changed completely since we use a format
e0db8cfb 889 instead of a protocol)
de6d9b64 890
0ca3e336 891
892version 0.4.2:
894- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
895 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 896 missing. MSMPEG4 support is complete.
897- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
898 can decode ffmpeg MPEGs :-)).
899- added libavcodec API documentation (see apiexample.c).
900- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 901 greenish)
de6d9b64 902- added support for non clipped motion vectors (decoding only)
903 and image sizes non-multiple of 16
904- added support for AC prediction (decoding only)
905- added file overwrite confirmation (can be disabled with -y)
906- added custom size picture to H.263 using H.263+ (Juanjo)
de6d9b64 907
0ca3e336 908
909version 0.4.1:
911- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
912 of AVI and ASF to DIV3.
913- added -me option to set motion estimation method
914 (default=log). suppressed redundant -hq option.
915- added options -acodec and -vcodec to force a given codec (useful for
916 AVI for example)
917- fixed -an option
918- improved dct_quantize speed
919- factorized some motion estimation code

922version 0.4.0:
924- removing grab code from ffserver and moved it to ffmpeg. Added
925 multistream support to ffmpeg.
de6d9b64 926- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 927 URL)
de6d9b64 928- added high quality image resize code with polyphase filter (need
56cc85a0 929 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 930- added multi live feed support in ffserver
931- suppressed master feature from ffserver (it should be done with an
932 external program which opens the .ffm url and writes it to another
933 ffserver)
934- added preliminary support for video stream parsing (WAV and AVI half
935 done). Added proper support for audio/video file conversion in
de6d9b64 936 ffmpeg.
937- added preliminary support for video file sending from ffserver
938- redesigning I/O subsystem: now using URL based input and output
939 (see avio.h)

941- added "tty user interface" to ffmpeg to stop grabbing gracefully
942- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
