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

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

841version 0.4.3:
dd5cf2ad 843- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)
844- fixed raw yuv output
845- added motion rounding support in MPEG-4
846- fixed motion bug rounding in MSMPEG4
847- added B-frame handling in video core
848- added full MPEG-1 decoding support
849- added partial (frame only) MPEG-2 support
de6d9b64 850- changed the FOURCC code for H.263 to "U263" to be able to see the
851 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
852 this +codec ;) (JuanJo).
853- Halfpel motion estimation after MB type selection (JuanJo)
854- added pgm and .Y.U.V output format
855- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
856 output.
857- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 858 <lists at>, but changed completely since we use a format
e0db8cfb 859 instead of a protocol)
de6d9b64 860
0ca3e336 861
862version 0.4.2:
864- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
865 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 866 missing. MSMPEG4 support is complete.
867- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
868 can decode ffmpeg MPEGs :-)).
869- added libavcodec API documentation (see apiexample.c).
870- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 871 greenish)
de6d9b64 872- added support for non clipped motion vectors (decoding only)
873 and image sizes non-multiple of 16
874- added support for AC prediction (decoding only)
875- added file overwrite confirmation (can be disabled with -y)
876- added custom size picture to H.263 using H.263+ (Juanjo)
de6d9b64 877

879version 0.4.1:
881- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
882 of AVI and ASF to DIV3.
883- added -me option to set motion estimation method
884 (default=log). suppressed redundant -hq option.
885- added options -acodec and -vcodec to force a given codec (useful for
886 AVI for example)
887- fixed -an option
888- improved dct_quantize speed
889- factorized some motion estimation code

892version 0.4.0:
894- removing grab code from ffserver and moved it to ffmpeg. Added
895 multistream support to ffmpeg.
de6d9b64 896- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 897 URL)
de6d9b64 898- added high quality image resize code with polyphase filter (need
56cc85a0 899 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 900- added multi live feed support in ffserver
901- suppressed master feature from ffserver (it should be done with an
902 external program which opens the .ffm url and writes it to another
903 ffserver)
904- added preliminary support for video stream parsing (WAV and AVI half
905 done). Added proper support for audio/video file conversion in
de6d9b64 906 ffmpeg.
907- added preliminary support for video file sending from ffserver
908- redesigning I/O subsystem: now using URL based input and output
909 (see avio.h)
910- added WAV format support
911- added "tty user interface" to ffmpeg to stop grabbing gracefully
912- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 913 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at>)
914- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
915- added new motion estimation algorithms, log and phods (Juanjo)
916- changed directories: libav for format handling, libavcodec for
917 codecs
