4d58e4cb 142- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
143- ffmpeg deprecated, added avconv, which is almost the same for now, except
144for a few incompatible changes in the options, which will hopefully make them
145easier to use. The changes are:
146 * The options placement is now strictly enforced! While in theory the
147 options for ffmpeg should be given in [input options] -i INPUT [output
148 options] OUTPUT order, in practice it was possible to give output options
149 before the -i and it mostly worked. Except when it didn't - the behavior was
150 a bit inconsistent. In avconv, it is not possible to mix input and output
151 options. All non-global options are reset after an input or output filename.
152 * All per-file options are now truly per-file - they apply only to the next
153 input or output file and specifying different values for different files
154 will now work properly (notably -ss and -t options).
155 * All per-stream options are now truly per-stream - it is possible to
156 specify which stream(s) should a given option apply to. See the Stream
157 specifiers section in the avconv manual for details.
158 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
159 sense that they're specified after the output filename instead of before,
160 like all other options. In avconv this irregularity is removed, all options
161 apply to the next input or output file.
162 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
163 irregular and highly confusing, they were also redundant. In avconv the -map
164 option will create new streams in the output file and map input streams to
165 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
166 each stream in the first input file.
167 * The -map option now has slightly different and more powerful syntax:
168 + Colons (':') are used to separate file index/stream type/stream index
169 instead of dots. Comma (',') is used to separate the sync stream instead
170 of colon.. This is done for consistency with other options.
171 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
172 output stream from the third input audio stream.
173 + Omitting the stream index now maps all the streams of the given type,
174 not just the first. E.g. -map 0:s creates output streams for all the
175 subtitle streams in the first input file.
176 + Since -map can now match multiple streams, negative mappings were
320d7693 177 introduced. Negative mappings disable some streams from an already
178 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
179 all the stream in the first input file, except for the second audio
180 stream'.
181 * There is a new option -c (or -codec) for choosing the decoder/encoder to
182 use, which allows to precisely specify target stream(s) consistently with
183 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
184 libvorbis sets the codec for the first audio stream and -c copy copies all
185 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
186 aliases to -c:v/a/s
320d7693 187 * It is now possible to precisely specify which stream should an AVOption
188 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
189 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
190 syntax is deprecated and will stop working soon.
191 * -map_chapters now takes only an input file index and applies to the next
192 output file. This is consistent with how all the other options work.
193 * -map_metadata now takes only an input metadata specifier and applies to
194 the next output file. Output metadata specifier is now part of the option
195 name, similarly to the AVOptions/map/codec feature above.
196 * -metadata can now be used to set metadata on streams and chapters, e.g.
197 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
198 This made -vlang/-alang/-slang options redundant, so they were removed.
199 * -qscale option now uses stream specifiers and applies to all streams, not
200 just video. I.e. plain -qscale number would now apply to all streams. To get
201 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
202 and -aq is now an alias for -q:a.
203 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
204 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
205 * -itsscale option now uses stream specifiers, so its argument is only the
206 scale parameter.
207 * -intra option was removed, use -g 0 for the same effect.
208 * -psnr option was removed, use -flags +psnr for the same effect.
209 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
210 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
211 * -vtag/-atag/-stag options are now aliases to the new -tag option.

836- added B-frame handling in video core
837- added full MPEG-1 decoding support
838- added partial (frame only) MPEG-2 support
de6d9b64 839- changed the FOURCC code for H.263 to "U263" to be able to see the
840 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
841 this +codec ;) (JuanJo).
842- Halfpel motion estimation after MB type selection (JuanJo)
843- added pgm and .Y.U.V output format
844- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
845 output.
846- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 847 <lists at>, but changed completely since we use a format
e0db8cfb 848 instead of a protocol)

851version 0.4.2:
853- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
854 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 855 missing. MSMPEG4 support is complete.
856- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
857 can decode ffmpeg MPEGs :-)).
858- added libavcodec API documentation (see apiexample.c).
859- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 860 greenish)
de6d9b64 861- added support for non clipped motion vectors (decoding only)
862 and image sizes non-multiple of 16
863- added support for AC prediction (decoding only)
864- added file overwrite confirmation (can be disabled with -y)
865- added custom size picture to H.263 using H.263+ (Juanjo)

868version 0.4.1:
870- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
871 of AVI and ASF to DIV3.
872- added -me option to set motion estimation method
873 (default=log). suppressed redundant -hq option.
874- added options -acodec and -vcodec to force a given codec (useful for
875 AVI for example)
876- fixed -an option
877- improved dct_quantize speed
878- factorized some motion estimation code

881version 0.4.0:
883- removing grab code from ffserver and moved it to ffmpeg. Added
884 multistream support to ffmpeg.
de6d9b64 885- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 886 URL)
de6d9b64 887- added high quality image resize code with polyphase filter (need
56cc85a0 888 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 889- added multi live feed support in ffserver
890- suppressed master feature from ffserver (it should be done with an
891 external program which opens the .ffm url and writes it to another
892 ffserver)
893- added preliminary support for video stream parsing (WAV and AVI half
894 done). Added proper support for audio/video file conversion in
de6d9b64 895 ffmpeg.
896- added preliminary support for video file sending from ffserver
897- redesigning I/O subsystem: now using URL based input and output
898 (see avio.h)
899- added WAV format support
900- added "tty user interface" to ffmpeg to stop grabbing gracefully
901- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 902 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at>)
903- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
904- added new motion estimation algorithms, log and phods (Juanjo)
905- changed directories: libav for format handling, libavcodec for
906 codecs

de6d9b64 912
0ca3e336 913
914version 0.3.3:
916- added 'high quality' mode which use motion vectors. It can be used in
917 real time at low resolution.
918- fixed rounding problems which caused quality problems at high
e0db8cfb 919 bitrates and large GOP size
de6d9b64 920
