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

e0db8cfb
DB
803 decoder)
804- added fractional frame rate support
de6d9b64 805- codecs are no longer searched by read_header() (should fix ffserver

de6d9b64 818- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
819 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
820 this +codec ;) (JuanJo).
821- Halfpel motion estimation after MB type selection (JuanJo)
822- added pgm and .Y.U.V output format
de6d9b64
FB

824 output.
825- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 826 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 827 instead of a protocol)
