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

e0db8cfb
DB
768- added MPEG demuxer (MPEG-1 and 2 compatible).
769- added ASF demuxer
770- added prototype RM demuxer
771- added AC3 decoding (done with libac3 by Aaron Holtzman)
772- added decoding codec parameter guessing (.e.g. for MPEG, because the

774- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
775 play them (only tested video)
776- fixed H.263 white bug
777- fixed phase rounding in img resample filter
778- add MMX code for polyphase img resample filter
779- added CPU autodetection
780- added generic title/author/copyright/comment string handling (ASF and RM
781 use them)
de6d9b64 782- added SWF demux to extract MP3 track (not usable yet because no MP3
e0db8cfb
DB
783 decoder)
784- added fractional frame rate support
de6d9b64 785- codecs are no longer searched by read_header() (should fix ffserver
e0db8cfb 786 segfault)

794- fixed motion bug rounding in MSMPEG4
795- added B-frame handling in video core
796- added full MPEG-1 decoding support
797- added partial (frame only) MPEG-2 support
de6d9b64 798- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
799 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
800 this +codec ;) (JuanJo).
801- Halfpel motion estimation after MB type selection (JuanJo)
802- added pgm and .Y.U.V output format
de6d9b64
FB
803- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
804 output.
805- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 806 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 807 instead of a protocol)

e0db8cfb
DB
812- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
813 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 814 missing. MSMPEG4 support is complete.
e0db8cfb
DB
815- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
816 can decode ffmpeg MPEGs :-)).
de6d9b64
FB
817- added libavcodec API documentation (see apiexample.c).
818- fixed image polyphase bug (the bottom of some images could be
e0db8cfb 819 greenish)
de6d9b64 820- added support for non clipped motion vectors (decoding only)
e0db8cfb
DB
821 and image sizes non-multiple of 16
822- added support for AC prediction (decoding only)
823- added file overwrite confirmation (can be disabled with -y)
824- added custom size picture to H.263 using H.263+ (Juanjo)

FB
831- added -me option to set motion estimation method
832 (default=log). suppressed redundant -hq option.
833- added options -acodec and -vcodec to force a given codec (useful for
e0db8cfb
DB
834 AVI for example)
835- fixed -an option
836- improved dct_quantize speed
837- factorized some motion estimation code

842- removing grab code from ffserver and moved it to ffmpeg. Added
843 multistream support to ffmpeg.
de6d9b64 844- added timeshifting support for live feeds (option ?date=xxx in the
e0db8cfb 845 URL)
de6d9b64 846- added high quality image resize code with polyphase filter (need
56cc85a0 847 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 848- added multi live feed support in ffserver
de6d9b64
FB
849- suppressed master feature from ffserver (it should be done with an
850 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
851 ffserver)
852- added preliminary support for video stream parsing (WAV and AVI half
853 done). Added proper support for audio/video file conversion in
de6d9b64 854 ffmpeg.
