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

832- added MPEG demuxer (MPEG-1 and 2 compatible).
833- added ASF demuxer
834- added prototype RM demuxer
835- added AC3 decoding (done with libac3 by Aaron Holtzman)
836- added decoding codec parameter guessing (.e.g. for MPEG, because the
837 header does not include them)
838- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
839 play them (only tested video)
840- fixed H.263 white bug
841- fixed phase rounding in img resample filter
842- add MMX code for polyphase img resample filter
843- added CPU autodetection
844- added generic title/author/copyright/comment string handling (ASF and RM
845 use them)
de6d9b64 846- added SWF demux to extract MP3 track (not usable yet because no MP3
847 decoder)
848- added fractional frame rate support
de6d9b64 849- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 850 segfault)

853version 0.4.3:
dd5cf2ad 855- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)
856- fixed raw yuv output
857- added motion rounding support in MPEG-4
858- fixed motion bug rounding in MSMPEG4
859- added B-frame handling in video core
860- added full MPEG-1 decoding support
861- added partial (frame only) MPEG-2 support
de6d9b64 862- changed the FOURCC code for H.263 to "U263" to be able to see the
863 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
864 this +codec ;) (JuanJo).
865- Halfpel motion estimation after MB type selection (JuanJo)
866- added pgm and .Y.U.V output format
867- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
868 output.
869- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 870 <lists at>, but changed completely since we use a format
e0db8cfb 871 instead of a protocol)
de6d9b64 872
0ca3e336 873
874version 0.4.2:
876- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
877 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 878 missing. MSMPEG4 support is complete.
879- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
880 can decode ffmpeg MPEGs :-)).
881- added libavcodec API documentation (see apiexample.c).
882- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 883 greenish)
de6d9b64 884- added support for non clipped motion vectors (decoding only)
885 and image sizes non-multiple of 16
886- added support for AC prediction (decoding only)
887- added file overwrite confirmation (can be disabled with -y)
888- added custom size picture to H.263 using H.263+ (Juanjo)
de6d9b64 889
0ca3e336 890
891version 0.4.1:
893- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
894 of AVI and ASF to DIV3.
895- added -me option to set motion estimation method
896 (default=log). suppressed redundant -hq option.
897- added options -acodec and -vcodec to force a given codec (useful for
898 AVI for example)
899- fixed -an option
900- improved dct_quantize speed
901- factorized some motion estimation code
de6d9b64 902
0ca3e336 903
904version 0.4.0:
906- removing grab code from ffserver and moved it to ffmpeg. Added
907 multistream support to ffmpeg.
de6d9b64 908- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 909 URL)
de6d9b64 910- added high quality image resize code with polyphase filter (need
56cc85a0 911 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 912- added multi live feed support in ffserver
913- suppressed master feature from ffserver (it should be done with an
914 external program which opens the .ffm url and writes it to another
915 ffserver)
916- added preliminary support for video stream parsing (WAV and AVI half
917 done). Added proper support for audio/video file conversion in
de6d9b64 918 ffmpeg.
919- added preliminary support for video file sending from ffserver
920- redesigning I/O subsystem: now using URL based input and output
921 (see avio.h)
922- added WAV format support
923- added "tty user interface" to ffmpeg to stop grabbing gracefully
924- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 925 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at>)
926- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
927- added new motion estimation algorithms, log and phods (Juanjo)
928- changed directories: libav for format handling, libavcodec for
929 codecs
