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

782- added prototype RM demuxer
783- added AC3 decoding (done with libac3 by Aaron Holtzman)
784- added decoding codec parameter guessing (.e.g. for MPEG, because the

e0db8cfb
DB
795 decoder)
796- added fractional frame rate support
de6d9b64 797- codecs are no longer searched by read_header() (should fix ffserver

de6d9b64 810- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
811 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
812 this +codec ;) (JuanJo).
813- Halfpel motion estimation after MB type selection (JuanJo)
814- added pgm and .Y.U.V output format
de6d9b64
FB
815- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
816 output.
817- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 818 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 819 instead of a protocol)

824- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
825 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
de6d9b64 826 missing. MSMPEG4 support is complete.
e0db8cfb
DB
827- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
828 can decode ffmpeg MPEGs :-)).
de6d9b64

e0db8cfb 831 greenish)
de6d9b64 832- added support for non clipped motion vectors (decoding only)
e0db8cfb

846 AVI for example)

e0db8cfb 857 URL)
de6d9b64 858- added high quality image resize code with polyphase filter (need
56cc85a0 859 mmx/see optimization). Enable multiple image size support in ffserver.
e0db8cfb 860- added multi live feed support in ffserver
de6d9b64

861- suppressed master feature from ffserver (it should be done with an
862 external program which opens the .ffm url and writes it to another
e0db8cfb
DB
863 ffserver)
864- added preliminary support for video stream parsing (WAV and AVI half
865 done). Added proper support for audio/video file conversion in
de6d9b64 866 ffmpeg.
