4d58e4cb 138- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
139- ffmpeg deprecated, added avconv, which is almost the same for now, except
140for a few incompatible changes in the options, which will hopefully make them
141easier to use. The changes are:
142 * The options placement is now strictly enforced! While in theory the
143 options for ffmpeg should be given in [input options] -i INPUT [output
144 options] OUTPUT order, in practice it was possible to give output options
145 before the -i and it mostly worked. Except when it didn't - the behavior was
146 a bit inconsistent. In avconv, it is not possible to mix input and output
147 options. All non-global options are reset after an input or output filename.
148 * All per-file options are now truly per-file - they apply only to the next
149 input or output file and specifying different values for different files
150 will now work properly (notably -ss and -t options).
151 * All per-stream options are now truly per-stream - it is possible to
152 specify which stream(s) should a given option apply to. See the Stream
153 specifiers section in the avconv manual for details.
154 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
155 sense that they're specified after the output filename instead of before,
156 like all other options. In avconv this irregularity is removed, all options
157 apply to the next input or output file.
158 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
159 irregular and highly confusing, they were also redundant. In avconv the -map
160 option will create new streams in the output file and map input streams to
161 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
162 each stream in the first input file.
163 * The -map option now has slightly different and more powerful syntax:
164 + Colons (':') are used to separate file index/stream type/stream index
165 instead of dots. Comma (',') is used to separate the sync stream instead
166 of colon.. This is done for consistency with other options.
167 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
168 output stream from the third input audio stream.
169 + Omitting the stream index now maps all the streams of the given type,
170 not just the first. E.g. -map 0:s creates output streams for all the
171 subtitle streams in the first input file.
172 + Since -map can now match multiple streams, negative mappings were
320d7693 173 introduced. Negative mappings disable some streams from an already
174 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
175 all the stream in the first input file, except for the second audio
176 stream'.
177 * There is a new option -c (or -codec) for choosing the decoder/encoder to
178 use, which allows to precisely specify target stream(s) consistently with
179 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
180 libvorbis sets the codec for the first audio stream and -c copy copies all
181 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
182 aliases to -c:v/a/s
320d7693 183 * It is now possible to precisely specify which stream should an AVOption
184 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
185 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
186 syntax is deprecated and will stop working soon.
187 * -map_chapters now takes only an input file index and applies to the next
188 output file. This is consistent with how all the other options work.
189 * -map_metadata now takes only an input metadata specifier and applies to
190 the next output file. Output metadata specifier is now part of the option
191 name, similarly to the AVOptions/map/codec feature above.
192 * -metadata can now be used to set metadata on streams and chapters, e.g.
193 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
194 This made -vlang/-alang/-slang options redundant, so they were removed.
195 * -qscale option now uses stream specifiers and applies to all streams, not
196 just video. I.e. plain -qscale number would now apply to all streams. To get
197 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
198 and -aq is now an alias for -q:a.
199 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
200 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
201 * -itsscale option now uses stream specifiers, so its argument is only the
202 scale parameter.
203 * -intra option was removed, use -g 0 for the same effect.
204 * -psnr option was removed, use -flags +psnr for the same effect.
205 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
206 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
207 * -vtag/-atag/-stag options are now aliases to the new -tag option.

de6d9b64 835- changed the FOURCC code for H.263 to "U263" to be able to see the
836 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
837 this +codec ;) (JuanJo).
838- Halfpel motion estimation after MB type selection (JuanJo)
839- added pgm and .Y.U.V output format
840- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
841 output.
842- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 843 <lists at>, but changed completely since we use a format
e0db8cfb 844 instead of a protocol)

847version 0.4.2:
849- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
850 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 851 missing. MSMPEG4 support is complete.
852- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
853 can decode ffmpeg MPEGs :-)).
854- added libavcodec API documentation (see apiexample.c).
855- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 856 greenish)
de6d9b64 857- added support for non clipped motion vectors (decoding only)
858 and image sizes non-multiple of 16
859- added support for AC prediction (decoding only)
860- added file overwrite confirmation (can be disabled with -y)
861- added custom size picture to H.263 using H.263+ (Juanjo)

864version 0.4.1:
866- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
867 of AVI and ASF to DIV3.
868- added -me option to set motion estimation method
869 (default=log). suppressed redundant -hq option.
870- added options -acodec and -vcodec to force a given codec (useful for
871 AVI for example)
872- fixed -an option
873- improved dct_quantize speed
874- factorized some motion estimation code

877version 0.4.0:
879- removing grab code from ffserver and moved it to ffmpeg. Added
880 multistream support to ffmpeg.
de6d9b64 881- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 882 URL)
de6d9b64 883- added high quality image resize code with polyphase filter (need
56cc85a0 884 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 885- added multi live feed support in ffserver
886- suppressed master feature from ffserver (it should be done with an
887 external program which opens the .ffm url and writes it to another
888 ffserver)
889- added preliminary support for video stream parsing (WAV and AVI half
890 done). Added proper support for audio/video file conversion in
de6d9b64 891 ffmpeg.
892- added preliminary support for video file sending from ffserver
893- redesigning I/O subsystem: now using URL based input and output
894 (see avio.h)
895- added WAV format support
896- added "tty user interface" to ffmpeg to stop grabbing gracefully
897- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 898 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at>)
899- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
900- added new motion estimation algorithms, log and phods (Juanjo)
901- changed directories: libav for format handling, libavcodec for
902 codecs

de6d9b64 908
0ca3e336 909
910version 0.3.3:
912- added 'high quality' mode which use motion vectors. It can be used in
913 real time at low resolution.
914- fixed rounding problems which caused quality problems at high
e0db8cfb 915 bitrates and large GOP size
de6d9b64 916
