AK
76- ffmpeg deprecated, added avconv, which is almost the same for now, except
77for a few incompatible changes in the options, which will hopefully make them
78easier to use. The changes are:
c4302a39
AK
79 * The options placement is now strictly enforced! While in theory the
80 options for ffmpeg should be given in [input options] -i INPUT [output
81 options] OUTPUT order, in practice it was possible to give output options
82 before the -i and it mostly worked. Except when it didn't - the behavior was
83 a bit inconsistent. In avconv, it is not possible to mix input and output
84 options. All non-global options are reset after an input or output filename.
85 * All per-file options are now truly per-file - they apply only to the next
86 input or output file and specifying different values for different files
87 will now work properly (notably -ss and -t options).
88 * All per-stream options are now truly per-stream - it is possible to
89 specify which stream(s) should a given option apply to. See the Stream
90 specifiers section in the avconv manual for details.
91 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
92 sense that they're specified after the output filename instead of before,
93 like all other options. In avconv this irregularity is removed, all options
94 apply to the next input or output file.
95 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
96 irregular and highly confusing, they were also redundant. In avconv the -map
97 option will create new streams in the output file and map input streams to
98 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
99 each stream in the first input file.
100 * The -map option now has slightly different and more powerful syntax:
101 + Colons (':') are used to separate file index/stream type/stream index
102 instead of dots. Comma (',') is used to separate the sync stream instead
103 of colon.. This is done for consistency with other options.
104 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
105 output stream from the third input audio stream.
106 + Omitting the stream index now maps all the streams of the given type,
107 not just the first. E.g. -map 0:s creates output streams for all the
108 subtitle streams in the first input file.
109 + Since -map can now match multiple streams, negative mappings were
320d7693 110 introduced. Negative mappings disable some streams from an already
c4302a39
AK
111 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
112 all the stream in the first input file, except for the second audio
113 stream'.
114 * There is a new option -c (or -codec) for choosing the decoder/encoder to
115 use, which allows to precisely specify target stream(s) consistently with
116 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
117 libvorbis sets the codec for the first audio stream and -c copy copies all
118 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
119 aliases to -c:v/a/s
320d7693 120 * It is now possible to precisely specify which stream should an AVOption
c4302a39
AK
121 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
122 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
123 syntax is deprecated and will stop working soon.
320d7693
AK
124 * -map_chapters now takes only an input file index and applies to the next
125 output file. This is consistent with how all the other options work.
126 * -map_metadata now takes only an input metadata specifier and applies to
127 the next output file. Output metadata specifier is now part of the option
128 name, similarly to the AVOptions/map/codec feature above.
c4302a39
AK
129 * -metadata can now be used to set metadata on streams and chapters, e.g.
130 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
131 This made -vlang/-alang/-slang options redundant, so they were removed.
132 * -qscale option now uses stream specifiers and applies to all streams, not
133 just video. I.e. plain -qscale number would now apply to all streams. To get
134 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
135 and -aq is now an alias for -q:a.
136 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
137 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
138 * -itsscale option now uses stream specifiers, so its argument is only the
139 scale parameter.
140 * -intra option was removed, use -g 0 for the same effect.
141 * -psnr option was removed, use -flags +psnr for the same effect.
142 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
143 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
144 * -vtag/-atag/-stag options are now aliases to the new -tag option.

769- added B-frame handling in video core
770- added full MPEG-1 decoding support
771- added partial (frame only) MPEG-2 support
de6d9b64 772- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
773 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
774 this +codec ;) (JuanJo).
775- Halfpel motion estimation after MB type selection (JuanJo)
776- added pgm and .Y.U.V output format
de6d9b64
FB
777- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
778 output.
779- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 780 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 781 instead of a protocol)

FB
784version 0.4.2:
785
e0db8cfb
DB
786- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
787 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 788 missing. MSMPEG4 support is complete.
e0db8cfb
DB
789- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
790 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
791- added libavcodec API documentation (see apiexample.c).
792- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 793 greenish)
de6d9b64 794- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
795 and image sizes non-multiple of 16
796- added support for AC prediction (decoding only)
797- added file overwrite confirmation (can be disabled with -y)
798- added custom size picture to H.263 using H.263+ (Juanjo)

801version 0.4.1:
802
e0db8cfb
DB
803- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
804 of AVI and ASF to DIV3.
de6d9b64
FB
805- added -me option to set motion estimation method
806 (default=log). suppressed redundant -hq option.
807- added options -acodec and -vcodec to force a given codec (useful for
e0db8cfb
DB
808 AVI for example)
809- fixed -an option
810- improved dct_quantize speed
811- factorized some motion estimation code

814version 0.4.0:
815
e0db8cfb
DB
816- removing grab code from ffserver and moved it to ffmpeg. Added
817 multistream support to ffmpeg.
de6d9b64 818- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 819 URL)
de6d9b64 820- added high quality image resize code with polyphase filter (need
56cc85a0 821 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 822- added multi live feed support in ffserver
de6d9b64
FB
823- suppressed master feature from ffserver (it should be done with an
824 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
825 ffserver)
826- added preliminary support for video stream parsing (WAV and AVI half
827 done). Added proper support for audio/video file conversion in
de6d9b64 828 ffmpeg.
e0db8cfb
DB
829- added preliminary support for video file sending from ffserver
830- redesigning I/O subsystem: now using URL based input and output
831 (see avio.h)
832- added WAV format support
833- added "tty user interface" to ffmpeg to stop grabbing gracefully
834- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
dd5cf2ad 835 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
e0db8cfb
DB
836- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
837- added new motion estimation algorithms, log and phods (Juanjo)
838- changed directories: libav for format handling, libavcodec for
839 codecs
