112- ffmpeg deprecated, added avconv, which is almost the same for now, except
113for a few incompatible changes in the options, which will hopefully make them
114easier to use. The changes are:
c4302a39
AK
115 * The options placement is now strictly enforced! While in theory the
116 options for ffmpeg should be given in [input options] -i INPUT [output
117 options] OUTPUT order, in practice it was possible to give output options
118 before the -i and it mostly worked. Except when it didn't - the behavior was
119 a bit inconsistent. In avconv, it is not possible to mix input and output
120 options. All non-global options are reset after an input or output filename.
121 * All per-file options are now truly per-file - they apply only to the next
122 input or output file and specifying different values for different files
123 will now work properly (notably -ss and -t options).
124 * All per-stream options are now truly per-stream - it is possible to
125 specify which stream(s) should a given option apply to. See the Stream
126 specifiers section in the avconv manual for details.
127 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
128 sense that they're specified after the output filename instead of before,
129 like all other options. In avconv this irregularity is removed, all options
130 apply to the next input or output file.
131 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
132 irregular and highly confusing, they were also redundant. In avconv the -map
133 option will create new streams in the output file and map input streams to
134 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
135 each stream in the first input file.
136 * The -map option now has slightly different and more powerful syntax:
137 + Colons (':') are used to separate file index/stream type/stream index
138 instead of dots. Comma (',') is used to separate the sync stream instead
139 of colon.. This is done for consistency with other options.
140 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
141 output stream from the third input audio stream.
142 + Omitting the stream index now maps all the streams of the given type,
143 not just the first. E.g. -map 0:s creates output streams for all the
144 subtitle streams in the first input file.
145 + Since -map can now match multiple streams, negative mappings were
320d7693 146 introduced. Negative mappings disable some streams from an already
c4302a39
AK
147 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
148 all the stream in the first input file, except for the second audio
149 stream'.
150 * There is a new option -c (or -codec) for choosing the decoder/encoder to
151 use, which allows to precisely specify target stream(s) consistently with
152 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
153 libvorbis sets the codec for the first audio stream and -c copy copies all
154 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
155 aliases to -c:v/a/s
320d7693 156 * It is now possible to precisely specify which stream should an AVOption
c4302a39
AK
157 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
158 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
159 syntax is deprecated and will stop working soon.
320d7693
AK
160 * -map_chapters now takes only an input file index and applies to the next
161 output file. This is consistent with how all the other options work.
162 * -map_metadata now takes only an input metadata specifier and applies to
163 the next output file. Output metadata specifier is now part of the option
164 name, similarly to the AVOptions/map/codec feature above.
c4302a39
AK
165 * -metadata can now be used to set metadata on streams and chapters, e.g.
166 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
167 This made -vlang/-alang/-slang options redundant, so they were removed.
168 * -qscale option now uses stream specifiers and applies to all streams, not
169 just video. I.e. plain -qscale number would now apply to all streams. To get
170 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
171 and -aq is now an alias for -q:a.
172 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
173 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
174 * -itsscale option now uses stream specifiers, so its argument is only the
175 scale parameter.
176 * -intra option was removed, use -g 0 for the same effect.
177 * -psnr option was removed, use -flags +psnr for the same effect.
178 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
179 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
180 * -vtag/-atag/-stag options are now aliases to the new -tag option.

774version 0.4.4:
775
776- fixed some std header definitions (Bjorn Lindgren

e0db8cfb
DB
778- added MPEG demuxer (MPEG-1 and 2 compatible).
779- added ASF demuxer
780- added prototype RM demuxer
781- added AC3 decoding (done with libac3 by Aaron Holtzman)
782- added decoding codec parameter guessing (.e.g. for MPEG, because the

785 play them (only tested video)
786- fixed H.263 white bug
787- fixed phase rounding in img resample filter
788- add MMX code for polyphase img resample filter
789- added CPU autodetection
790- added generic title/author/copyright/comment string handling (ASF and RM
791 use them)
de6d9b64 792- added SWF demux to extract MP3 track (not usable yet because no MP3
e0db8cfb
DB
793 decoder)
794- added fractional frame rate support
de6d9b64 795- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 796 segfault)

807- added partial (frame only) MPEG-2 support
de6d9b64 808- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
809 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
810 this +codec ;) (JuanJo).
811- Halfpel motion estimation after MB type selection (JuanJo)
812- added pgm and .Y.U.V output format
de6d9b64
FB
813- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
814 output.
815- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 816 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 817 instead of a protocol)

820version 0.4.2:
821
e0db8cfb
DB
822- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
823 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 824 missing. MSMPEG4 support is complete.
e0db8cfb
DB
825- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
826 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
827- added libavcodec API documentation (see apiexample.c).
828- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 829 greenish)
de6d9b64 830- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
831 and image sizes non-multiple of 16
832- added support for AC prediction (decoding only)
833- added file overwrite confirmation (can be disabled with -y)
834- added custom size picture to H.263 using H.263+ (Juanjo)

840 of AVI and ASF to DIV3.
de6d9b64
FB
841- added -me option to set motion estimation method
842 (default=log). suppressed redundant -hq option.
843- added options -acodec and -vcodec to force a given codec (useful for
e0db8cfb
DB
844 AVI for example)
845- fixed -an option
846- improved dct_quantize speed
847- factorized some motion estimation code

853 multistream support to ffmpeg.
de6d9b64 854- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 855 URL)
de6d9b64 856- added high quality image resize code with polyphase filter (need
56cc85a0 857 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 858- added multi live feed support in ffserver
de6d9b64
FB
859- suppressed master feature from ffserver (it should be done with an
860 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
861 ffserver)
862- added preliminary support for video stream parsing (WAV and AVI half
863 done). Added proper support for audio/video file conversion in
de6d9b64 864 ffmpeg.
e0db8cfb
