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

  1000. - Halfpel motion estimation after MB type selection (JuanJo)
  1001. - added pgm and .Y.U.V output format
  1002. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or

  1037. mmx/see optimization). Enable multiple image size support in ffserver.
  1038. - added multi live feed support in ffserver
  1039. - suppressed master feature from ffserver (it should be done with an
  1040. external program which opens the .ffm url and writes it to another
  1041. ffserver)
  1042. - added preliminary support for video stream parsing (WAV and AVI half
  1043. done). Added proper support for audio/video file conversion in
  1044. ffmpeg.
