235 - Flash Screen Video 2 decoder
236 - lavfi input device added
237 - added avconv, which is almost the same for now, except
238 for a few incompatible changes in the options, which will hopefully make them
239 easier to use. The changes are:
240 * The options placement is now strictly enforced! While in theory the
241 options for ffmpeg should be given in [input options] -i INPUT [output
242 options] OUTPUT order, in practice it was possible to give output options
243 before the -i and it mostly worked. Except when it didn't - the behavior was
244 a bit inconsistent. In avconv, it is not possible to mix input and output
245 options. All non-global options are reset after an input or output filename.
246 * All per-file options are now truly per-file - they apply only to the next
247 input or output file and specifying different values for different files
248 will now work properly (notably -ss and -t options).
249 * All per-stream options are now truly per-stream - it is possible to
250 specify which stream(s) should a given option apply to. See the Stream
251 specifiers section in the avconv manual for details.
252 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
253 sense that they're specified after the output filename instead of before,
254 like all other options. In avconv this irregularity is removed, all options
255 apply to the next input or output file.
256 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
257 irregular and highly confusing, they were also redundant. In avconv the -map
258 option will create new streams in the output file and map input streams to
259 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
260 each stream in the first input file.
261 * The -map option now has slightly different and more powerful syntax:
262 + Colons (':') are used to separate file index/stream type/stream index
263 instead of dots. Comma (',') is used to separate the sync stream instead
264 of colon.. This is done for consistency with other options.
265 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
266 output stream from the third input audio stream.
267 + Omitting the stream index now maps all the streams of the given type,
268 not just the first. E.g. -map 0:s creates output streams for all the
269 subtitle streams in the first input file.
270 + Since -map can now match multiple streams, negative mappings were
271 introduced. Negative mappings disable some streams from an already
272 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
273 all the stream in the first input file, except for the second audio
275 * There is a new option -c (or -codec) for choosing the decoder/encoder to
276 use, which allows to precisely specify target stream(s) consistently with
277 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
278 libvorbis sets the codec for the first audio stream and -c copy copies all
279 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
281 * It is now possible to precisely specify which stream should an AVOption
282 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
283 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
284 syntax is deprecated and will stop working soon.
285 * -map_chapters now takes only an input file index and applies to the next
286 output file. This is consistent with how all the other options work.
287 * -map_metadata now takes only an input metadata specifier and applies to
288 the next output file. Output metadata specifier is now part of the option
289 name, similarly to the AVOptions/map/codec feature above.
290 * -metadata can now be used to set metadata on streams and chapters, e.g.
291 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
292 This made -vlang/-alang/-slang options redundant, so they were removed.
293 * -qscale option now uses stream specifiers and applies to all streams, not
294 just video. I.e. plain -qscale number would now apply to all streams. To get
295 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
296 and -aq is now an alias for -q:a.
297 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
298 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
299 * -itsscale option now uses stream specifiers, so its argument is only the
301 * -intra option was removed, use -g 0 for the same effect.
302 * -psnr option was removed, use -flags +psnr for the same effect.
303 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
304 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
305 * -vtag/-atag/-stag options are now aliases to the new -tag option.
