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

  918. version 0.4.4:
  919. - fixed some std header definitions (Bjorn Lindgren
  920. <bjorn.e.lindgren at telia.com>).
  921. - added MPEG demuxer (MPEG-1 and 2 compatible).
  922. - added ASF demuxer
  923. - added prototype RM demuxer
  924. - added AC3 decoding (done with libac3 by Aaron Holtzman)
  925. - added decoding codec parameter guessing (.e.g. for MPEG, because the
  926. header does not include them)
  927. - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
  928. play them (only tested video)
  929. - fixed H.263 white bug
  930. - fixed phase rounding in img resample filter
  931. - add MMX code for polyphase img resample filter
  932. - added CPU autodetection
  933. - added generic title/author/copyright/comment string handling (ASF and RM
  934. use them)
  935. - added SWF demux to extract MP3 track (not usable yet because no MP3
  936. decoder)
  937. - added fractional frame rate support
  938. - codecs are no longer searched by read_header() (should fix ffserver
  939. segfault)
  940. version 0.4.3:
  941. - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

  947. - added partial (frame only) MPEG-2 support
  948. - changed the FOURCC code for H.263 to "U263" to be able to see the
  949. +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
  950. this +codec ;) (JuanJo).
  951. - Halfpel motion estimation after MB type selection (JuanJo)
  952. - added pgm and .Y.U.V output format
  953. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
  954. output.
  955. - added pgmpipe I/O format (original patch from Martin Aumueller
  956. <lists at reserv.at>, but changed completely since we use a format
  957. instead of a protocol)
  958. version 0.4.2:
  959. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
  960. (for OpenDivX) is almost complete: 8x8 MVs and rounding are
  961. missing. MSMPEG4 support is complete.
  962. - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
  963. can decode ffmpeg MPEGs :-)).
  964. - added libavcodec API documentation (see apiexample.c).
  965. - fixed image polyphase bug (the bottom of some images could be
  966. greenish)
  967. - added support for non clipped motion vectors (decoding only)
  968. and image sizes non-multiple of 16
  969. - added support for AC prediction (decoding only)
  970. - added file overwrite confirmation (can be disabled with -y)
  971. - added custom size picture to H.263 using H.263+ (Juanjo)
  972. version 0.4.1:
  973. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
  974. of AVI and ASF to DIV3.
  975. - added -me option to set motion estimation method
  976. (default=log). suppressed redundant -hq option.
  977. - added options -acodec and -vcodec to force a given codec (useful for
  978. AVI for example)
  979. - fixed -an option
  980. - improved dct_quantize speed
  981. - factorized some motion estimation code
  982. version 0.4.0:
  983. - removing grab code from ffserver and moved it to ffmpeg. Added
  984. multistream support to ffmpeg.
  985. - added timeshifting support for live feeds (option ?date=xxx in the
  986. URL)
  987. - added high quality image resize code with polyphase filter (need
  988. mmx/see optimization). Enable multiple image size support in ffserver.
  989. - added multi live feed support in ffserver
  990. - suppressed master feature from ffserver (it should be done with an
  991. external program which opens the .ffm url and writes it to another
  992. ffserver)
  993. - added preliminary support for video stream parsing (WAV and AVI half
  994. done). Added proper support for audio/video file conversion in
  995. ffmpeg.
  996. - added preliminary support for video file sending from ffserver
  997. - redesigning I/O subsystem: now using URL based input and output
  998. (see avio.h)
  999. - added WAV format support
  1000. - added "tty user interface" to ffmpeg to stop grabbing gracefully
  1001. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
  1002. (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
  1003. - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
  1004. - added new motion estimation algorithms, log and phods (Juanjo)
  1005. - changed directories: libav for format handling, libavcodec for
  1006. codecs
  1007. version 0.3.4:
  1008. - added stereo in MPEG audio encoder
  1009. version 0.3.3:
  1010. - added 'high quality' mode which use motion vectors. It can be used in
  1011. real time at low resolution.
  1012. - fixed rounding problems which caused quality problems at high
  1013. bitrates and large GOP size
  1014. version 0.3.2: small fixes
  1015. - ASF fixes
  1016. - put_seek bug fix
  1017. version 0.3.1: added avi/divx support
