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

846- added MPEG demuxer (MPEG-1 and 2 compatible).
847- added ASF demuxer
848- added prototype RM demuxer
849- added AC3 decoding (done with libac3 by Aaron Holtzman)
850- added decoding codec parameter guessing (.e.g. for MPEG, because the
851 header does not include them)
852- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
853 play them (only tested video)
854- fixed H.263 white bug
855- fixed phase rounding in img resample filter
856- add MMX code for polyphase img resample filter
857- added CPU autodetection

861 decoder)
862- added fractional frame rate support
de6d9b64 863- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 864 segfault)

867version 0.4.3:
dd5cf2ad 869- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at>)

874- added full MPEG-1 decoding support
875- added partial (frame only) MPEG-2 support
de6d9b64 876- changed the FOURCC code for H.263 to "U263" to be able to see the
877 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
878 this +codec ;) (JuanJo).
879- Halfpel motion estimation after MB type selection (JuanJo)
880- added pgm and .Y.U.V output format
881- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
882 output.
883- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 884 <lists at>, but changed completely since we use a format
e0db8cfb 885 instead of a protocol)
de6d9b64 886
0ca3e336 887
888version 0.4.2:
890- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
891 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 892 missing. MSMPEG4 support is complete.
893- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
894 can decode ffmpeg MPEGs :-)).
895- added libavcodec API documentation (see apiexample.c).
896- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 897 greenish)
de6d9b64 898- added support for non clipped motion vectors (decoding only)
899 and image sizes non-multiple of 16
900- added support for AC prediction (decoding only)
901- added file overwrite confirmation (can be disabled with -y)
902- added custom size picture to H.263 using H.263+ (Juanjo)
de6d9b64 903
0ca3e336 904
905version 0.4.1:
907- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
908 of AVI and ASF to DIV3.
909- added -me option to set motion estimation method
910 (default=log). suppressed redundant -hq option.
911- added options -acodec and -vcodec to force a given codec (useful for
912 AVI for example)
913- fixed -an option
914- improved dct_quantize speed
915- factorized some motion estimation code

918version 0.4.0:
920- removing grab code from ffserver and moved it to ffmpeg. Added
921 multistream support to ffmpeg.
de6d9b64 922- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 923 URL)
de6d9b64 924- added high quality image resize code with polyphase filter (need
56cc85a0 925 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 926- added multi live feed support in ffserver
927- suppressed master feature from ffserver (it should be done with an
928 external program which opens the .ffm url and writes it to another
929 ffserver)
930- added preliminary support for video stream parsing (WAV and AVI half
931 done). Added proper support for audio/video file conversion in
de6d9b64 932 ffmpeg.
933- added preliminary support for video file sending from ffserver
934- redesigning I/O subsystem: now using URL based input and output
935 (see avio.h)
936- added WAV format support
937- added "tty user interface" to ffmpeg to stop grabbing gracefully
938- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
