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

831- add MMX code for polyphase img resample filter
832- added CPU autodetection
833- added generic title/author/copyright/comment string handling (ASF and RM
834 use them)
de6d9b64 835- added SWF demux to extract MP3 track (not usable yet because no MP3
836 decoder)
837- added fractional frame rate support
de6d9b64 838- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 839 segfault)

842version 0.4.3:
dd5cf2ad 844- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)
845- fixed raw yuv output
846- added motion rounding support in MPEG-4
847- fixed motion bug rounding in MSMPEG4
848- added B-frame handling in video core
849- added full MPEG-1 decoding support
850- added partial (frame only) MPEG-2 support
de6d9b64 851- changed the FOURCC code for H.263 to "U263" to be able to see the
852 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
853 this +codec ;) (JuanJo).
854- Halfpel motion estimation after MB type selection (JuanJo)
855- added pgm and .Y.U.V output format
856- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
857 output.
858- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 859 <lists at>, but changed completely since we use a format
e0db8cfb 860 instead of a protocol)
de6d9b64 861
0ca3e336 862
863version 0.4.2:
865- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
866 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 867 missing. MSMPEG4 support is complete.
868- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
869 can decode ffmpeg MPEGs :-)).
870- added libavcodec API documentation (see apiexample.c).
871- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 872 greenish)
de6d9b64 873- added support for non clipped motion vectors (decoding only)
874 and image sizes non-multiple of 16
875- added support for AC prediction (decoding only)
876- added file overwrite confirmation (can be disabled with -y)
877- added custom size picture to H.263 using H.263+ (Juanjo)
de6d9b64 878

880version 0.4.1:
882- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
883 of AVI and ASF to DIV3.
884- added -me option to set motion estimation method
885 (default=log). suppressed redundant -hq option.
886- added options -acodec and -vcodec to force a given codec (useful for
887 AVI for example)
888- fixed -an option
889- improved dct_quantize speed
890- factorized some motion estimation code

893version 0.4.0:
895- removing grab code from ffserver and moved it to ffmpeg. Added
896 multistream support to ffmpeg.
de6d9b64 897- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 898 URL)
de6d9b64 899- added high quality image resize code with polyphase filter (need
56cc85a0 900 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 901- added multi live feed support in ffserver
902- suppressed master feature from ffserver (it should be done with an
903 external program which opens the .ffm url and writes it to another
904 ffserver)
905- added preliminary support for video stream parsing (WAV and AVI half
906 done). Added proper support for audio/video file conversion in
de6d9b64 907 ffmpeg.
908- added preliminary support for video file sending from ffserver
909- redesigning I/O subsystem: now using URL based input and output
910 (see avio.h)
911- added WAV format support
912- added "tty user interface" to ffmpeg to stop grabbing gracefully
913- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 914 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at>)
915- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
916- added new motion estimation algorithms, log and phods (Juanjo)
917- changed directories: libav for format handling, libavcodec for
918 codecs
