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

831- added MPEG demuxer (MPEG-1 and 2 compatible).
832- added ASF demuxer
833- added prototype RM demuxer
834- added AC3 decoding (done with libac3 by Aaron Holtzman)
835- added decoding codec parameter guessing (.e.g. for MPEG, because the
836 header does not include them)
837- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
838 play them (only tested video)
839- fixed H.263 white bug
840- fixed phase rounding in img resample filter
841- add MMX code for polyphase img resample filter
842- added CPU autodetection
843- added generic title/author/copyright/comment string handling (ASF and RM
844 use them)
de6d9b64 845- added SWF demux to extract MP3 track (not usable yet because no MP3
846 decoder)
847- added fractional frame rate support
de6d9b64 848- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 849 segfault)

852version 0.4.3:
dd5cf2ad 854- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)
855- fixed raw yuv output
856- added motion rounding support in MPEG-4
857- fixed motion bug rounding in MSMPEG4
858- added B-frame handling in video core
859- added full MPEG-1 decoding support
860- added partial (frame only) MPEG-2 support
de6d9b64 861- changed the FOURCC code for H.263 to "U263" to be able to see the
862 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
863 this +codec ;) (JuanJo).
864- Halfpel motion estimation after MB type selection (JuanJo)
865- added pgm and .Y.U.V output format
866- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
867 output.
868- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 869 <lists at>, but changed completely since we use a format
e0db8cfb 870 instead of a protocol)
de6d9b64 871
0ca3e336 872
873version 0.4.2:
875- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
876 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 877 missing. MSMPEG4 support is complete.
878- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
879 can decode ffmpeg MPEGs :-)).
880- added libavcodec API documentation (see apiexample.c).
881- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 882 greenish)
de6d9b64 883- added support for non clipped motion vectors (decoding only)
884 and image sizes non-multiple of 16
885- added support for AC prediction (decoding only)
886- added file overwrite confirmation (can be disabled with -y)
887- added custom size picture to H.263 using H.263+ (Juanjo)
de6d9b64 888

890version 0.4.1:
892- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
893 of AVI and ASF to DIV3.
894- added -me option to set motion estimation method
895 (default=log). suppressed redundant -hq option.
896- added options -acodec and -vcodec to force a given codec (useful for
897 AVI for example)
898- fixed -an option
899- improved dct_quantize speed
900- factorized some motion estimation code
de6d9b64 901

903version 0.4.0:
905- removing grab code from ffserver and moved it to ffmpeg. Added
906 multistream support to ffmpeg.
de6d9b64 907- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 908 URL)
de6d9b64 909- added high quality image resize code with polyphase filter (need
56cc85a0 910 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 911- added multi live feed support in ffserver
912- suppressed master feature from ffserver (it should be done with an
913 external program which opens the .ffm url and writes it to another
914 ffserver)
915- added preliminary support for video stream parsing (WAV and AVI half
916 done). Added proper support for audio/video file conversion in
de6d9b64 917 ffmpeg.
918- added preliminary support for video file sending from ffserver
919- redesigning I/O subsystem: now using URL based input and output
920 (see avio.h)
921- added WAV format support
922- added "tty user interface" to ffmpeg to stop grabbing gracefully
923- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 924 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at>)
925- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
926- added new motion estimation algorithms, log and phods (Juanjo)
927- changed directories: libav for format handling, libavcodec for
928 codecs
