c2d23309 275- Flash Screen Video 2 decoder
4d58e4cb 276- ffplay/ffprobe/ffserver renamed to avplay/avprobe/avserver
277- ffmpeg deprecated, added avconv, which is almost the same for now, except
278for a few incompatible changes in the options, which will hopefully make them
279easier to use. The changes are:
280 * The options placement is now strictly enforced! While in theory the
281 options for ffmpeg should be given in [input options] -i INPUT [output
282 options] OUTPUT order, in practice it was possible to give output options
283 before the -i and it mostly worked. Except when it didn't - the behavior was
284 a bit inconsistent. In avconv, it is not possible to mix input and output
285 options. All non-global options are reset after an input or output filename.
286 * All per-file options are now truly per-file - they apply only to the next
287 input or output file and specifying different values for different files
288 will now work properly (notably -ss and -t options).
289 * All per-stream options are now truly per-stream - it is possible to
290 specify which stream(s) should a given option apply to. See the Stream
291 specifiers section in the avconv manual for details.
292 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
293 sense that they're specified after the output filename instead of before,
294 like all other options. In avconv this irregularity is removed, all options
295 apply to the next input or output file.
296 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
297 irregular and highly confusing, they were also redundant. In avconv the -map
298 option will create new streams in the output file and map input streams to
299 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
300 each stream in the first input file.
301 * The -map option now has slightly different and more powerful syntax:
302 + Colons (':') are used to separate file index/stream type/stream index
303 instead of dots. Comma (',') is used to separate the sync stream instead
304 of colon.. This is done for consistency with other options.
305 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
306 output stream from the third input audio stream.
307 + Omitting the stream index now maps all the streams of the given type,
308 not just the first. E.g. -map 0:s creates output streams for all the
309 subtitle streams in the first input file.
310 + Since -map can now match multiple streams, negative mappings were
320d7693 311 introduced. Negative mappings disable some streams from an already
312 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
313 all the stream in the first input file, except for the second audio
314 stream'.
315 * There is a new option -c (or -codec) for choosing the decoder/encoder to
316 use, which allows to precisely specify target stream(s) consistently with
317 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
318 libvorbis sets the codec for the first audio stream and -c copy copies all
319 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
320 aliases to -c:v/a/s
320d7693 321 * It is now possible to precisely specify which stream should an AVOption
322 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
323 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
324 syntax is deprecated and will stop working soon.
325 * -map_chapters now takes only an input file index and applies to the next
326 output file. This is consistent with how all the other options work.
327 * -map_metadata now takes only an input metadata specifier and applies to
328 the next output file. Output metadata specifier is now part of the option
329 name, similarly to the AVOptions/map/codec feature above.
330 * -metadata can now be used to set metadata on streams and chapters, e.g.
331 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
332 This made -vlang/-alang/-slang options redundant, so they were removed.
333 * -qscale option now uses stream specifiers and applies to all streams, not
334 just video. I.e. plain -qscale number would now apply to all streams. To get
335 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
336 and -aq is now an alias for -q:a.
337 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
338 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
339 * -itsscale option now uses stream specifiers, so its argument is only the
340 scale parameter.
341 * -intra option was removed, use -g 0 for the same effect.
342 * -psnr option was removed, use -flags +psnr for the same effect.
343 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
344 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
345 * -vtag/-atag/-stag options are now aliases to the new -tag option.
