92- ffmpeg deprecated, added avconv, which is almost the same for now, except
93for a few incompatible changes in the options, which will hopefully make them
94easier to use. The changes are:
c4302a39
AK
95 * The options placement is now strictly enforced! While in theory the
96 options for ffmpeg should be given in [input options] -i INPUT [output
97 options] OUTPUT order, in practice it was possible to give output options
98 before the -i and it mostly worked. Except when it didn't - the behavior was
99 a bit inconsistent. In avconv, it is not possible to mix input and output
100 options. All non-global options are reset after an input or output filename.
101 * All per-file options are now truly per-file - they apply only to the next
102 input or output file and specifying different values for different files
103 will now work properly (notably -ss and -t options).
104 * All per-stream options are now truly per-stream - it is possible to
105 specify which stream(s) should a given option apply to. See the Stream
106 specifiers section in the avconv manual for details.
107 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
108 sense that they're specified after the output filename instead of before,
109 like all other options. In avconv this irregularity is removed, all options
110 apply to the next input or output file.
111 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
112 irregular and highly confusing, they were also redundant. In avconv the -map
113 option will create new streams in the output file and map input streams to
114 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
115 each stream in the first input file.
116 * The -map option now has slightly different and more powerful syntax:
117 + Colons (':') are used to separate file index/stream type/stream index
118 instead of dots. Comma (',') is used to separate the sync stream instead
119 of colon.. This is done for consistency with other options.
120 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
121 output stream from the third input audio stream.
122 + Omitting the stream index now maps all the streams of the given type,
123 not just the first. E.g. -map 0:s creates output streams for all the
124 subtitle streams in the first input file.
125 + Since -map can now match multiple streams, negative mappings were
320d7693 126 introduced. Negative mappings disable some streams from an already
c4302a39
AK
127 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
128 all the stream in the first input file, except for the second audio
129 stream'.
130 * There is a new option -c (or -codec) for choosing the decoder/encoder to
131 use, which allows to precisely specify target stream(s) consistently with
132 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
133 libvorbis sets the codec for the first audio stream and -c copy copies all
134 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
135 aliases to -c:v/a/s
320d7693 136 * It is now possible to precisely specify which stream should an AVOption
c4302a39
AK
137 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
138 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
139 syntax is deprecated and will stop working soon.
320d7693
AK
140 * -map_chapters now takes only an input file index and applies to the next
141 output file. This is consistent with how all the other options work.
142 * -map_metadata now takes only an input metadata specifier and applies to
143 the next output file. Output metadata specifier is now part of the option
144 name, similarly to the AVOptions/map/codec feature above.
c4302a39
AK
145 * -metadata can now be used to set metadata on streams and chapters, e.g.
146 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
147 This made -vlang/-alang/-slang options redundant, so they were removed.
148 * -qscale option now uses stream specifiers and applies to all streams, not
149 just video. I.e. plain -qscale number would now apply to all streams. To get
150 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
151 and -aq is now an alias for -q:a.
152 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
153 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
154 * -itsscale option now uses stream specifiers, so its argument is only the
155 scale parameter.
156 * -intra option was removed, use -g 0 for the same effect.
157 * -psnr option was removed, use -flags +psnr for the same effect.
158 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
159 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
160 * -vtag/-atag/-stag options are now aliases to the new -tag option.

770- added generic title/author/copyright/comment string handling (ASF and RM
771 use them)
de6d9b64 772- added SWF demux to extract MP3 track (not usable yet because no MP3
e0db8cfb
DB
773 decoder)
774- added fractional frame rate support
de6d9b64 775- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 776 segfault)

779version 0.4.3:
780
dd5cf2ad 781- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
e0db8cfb
DB
782- fixed raw yuv output
783- added motion rounding support in MPEG-4
784- fixed motion bug rounding in MSMPEG4
785- added B-frame handling in video core
786- added full MPEG-1 decoding support
787- added partial (frame only) MPEG-2 support
de6d9b64 788- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
789 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
790 this +codec ;) (JuanJo).
791- Halfpel motion estimation after MB type selection (JuanJo)
792- added pgm and .Y.U.V output format
de6d9b64
FB
793- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
794 output.
795- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 796 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 797 instead of a protocol)

800version 0.4.2:
801
e0db8cfb
DB
802- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
803 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 804 missing. MSMPEG4 support is complete.
e0db8cfb
DB
805- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
806 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
807- added libavcodec API documentation (see apiexample.c).
808- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 809 greenish)
de6d9b64 810- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
811 and image sizes non-multiple of 16
812- added support for AC prediction (decoding only)
813- added file overwrite confirmation (can be disabled with -y)
814- added custom size picture to H.263 using H.263+ (Juanjo)

819- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
820 of AVI and ASF to DIV3.
de6d9b64
FB
821- added -me option to set motion estimation method
822 (default=log). suppressed redundant -hq option.
823- added options -acodec and -vcodec to force a given codec (useful for
e0db8cfb
DB
824 AVI for example)
825- fixed -an option
826- improved dct_quantize speed
827- factorized some motion estimation code

830version 0.4.0:
831

832- removing grab code from ffserver and moved it to ffmpeg. Added
833 multistream support to ffmpeg.
de6d9b64 834- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 835 URL)
de6d9b64 836- added high quality image resize code with polyphase filter (need
56cc85a0 837 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 838- added multi live feed support in ffserver
de6d9b64
FB
839- suppressed master feature from ffserver (it should be done with an
840 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
841 ffserver)
842- added preliminary support for video stream parsing (WAV and AVI half
843 done). Added proper support for audio/video file conversion in
de6d9b64 844 ffmpeg.
e0db8cfb
DB
845- added preliminary support for video file sending from ffserver
846- redesigning I/O subsystem: now using URL based input and output
847 (see avio.h)
848- added WAV format support
849- added "tty user interface" to ffmpeg to stop grabbing gracefully
850- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
