182 - Flash Screen Video 2 decoder
183 - lavfi input device added
184 - added avconv, which is almost the same for now, except
185 for a few incompatible changes in the options, which will hopefully make them
186 easier to use. The changes are:
187 * The options placement is now strictly enforced! While in theory the
188 options for ffmpeg should be given in [input options] -i INPUT [output
189 options] OUTPUT order, in practice it was possible to give output options
190 before the -i and it mostly worked. Except when it didn't - the behavior was
191 a bit inconsistent. In avconv, it is not possible to mix input and output
192 options. All non-global options are reset after an input or output filename.
193 * All per-file options are now truly per-file - they apply only to the next
194 input or output file and specifying different values for different files
195 will now work properly (notably -ss and -t options).
196 * All per-stream options are now truly per-stream - it is possible to
197 specify which stream(s) should a given option apply to. See the Stream
198 specifiers section in the avconv manual for details.
199 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
200 sense that they're specified after the output filename instead of before,
201 like all other options. In avconv this irregularity is removed, all options
202 apply to the next input or output file.
203 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
204 irregular and highly confusing, they were also redundant. In avconv the -map
205 option will create new streams in the output file and map input streams to
206 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
207 each stream in the first input file.
208 * The -map option now has slightly different and more powerful syntax:
209 + Colons (':') are used to separate file index/stream type/stream index
210 instead of dots. Comma (',') is used to separate the sync stream instead
211 of colon.. This is done for consistency with other options.
212 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
213 output stream from the third input audio stream.
214 + Omitting the stream index now maps all the streams of the given type,
215 not just the first. E.g. -map 0:s creates output streams for all the
216 subtitle streams in the first input file.
217 + Since -map can now match multiple streams, negative mappings were
218 introduced. Negative mappings disable some streams from an already
219 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
220 all the stream in the first input file, except for the second audio
222 * There is a new option -c (or -codec) for choosing the decoder/encoder to
223 use, which allows to precisely specify target stream(s) consistently with
224 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
225 libvorbis sets the codec for the first audio stream and -c copy copies all
226 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
228 * It is now possible to precisely specify which stream should an AVOption
229 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
230 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
231 syntax is deprecated and will stop working soon.
232 * -map_chapters now takes only an input file index and applies to the next
233 output file. This is consistent with how all the other options work.
234 * -map_metadata now takes only an input metadata specifier and applies to
235 the next output file. Output metadata specifier is now part of the option
236 name, similarly to the AVOptions/map/codec feature above.
237 * -metadata can now be used to set metadata on streams and chapters, e.g.
238 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
239 This made -vlang/-alang/-slang options redundant, so they were removed.
240 * -qscale option now uses stream specifiers and applies to all streams, not
241 just video. I.e. plain -qscale number would now apply to all streams. To get
242 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
243 and -aq is now an alias for -q:a.
244 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
245 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
246 * -itsscale option now uses stream specifiers, so its argument is only the
248 * -intra option was removed, use -g 0 for the same effect.
249 * -psnr option was removed, use -flags +psnr for the same effect.
250 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
251 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
252 * -vtag/-atag/-stag options are now aliases to the new -tag option.
