  724. - openal input device added
  725. - boxblur filter added
  726. - BWF muxer
  727. - Flash Screen Video 2 decoder
  728. - lavfi input device added
  729. - added avconv, which is almost the same for now, except
  730. for a few incompatible changes in the options, which will hopefully make them
  731. easier to use. The changes are:
  732. * The options placement is now strictly enforced! While in theory the
  733. options for ffmpeg should be given in [input options] -i INPUT [output
  734. options] OUTPUT order, in practice it was possible to give output options
  735. before the -i and it mostly worked. Except when it didn't - the behavior was
  736. a bit inconsistent. In avconv, it is not possible to mix input and output
  737. options. All non-global options are reset after an input or output filename.
  738. * All per-file options are now truly per-file - they apply only to the next
  739. input or output file and specifying different values for different files
  740. will now work properly (notably -ss and -t options).
  741. * All per-stream options are now truly per-stream - it is possible to
  742. specify which stream(s) should a given option apply to. See the Stream
  743. specifiers section in the avconv manual for details.
  744. * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
  745. sense that they're specified after the output filename instead of before,
  746. like all other options. In avconv this irregularity is removed, all options
  747. apply to the next input or output file.
  748. * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
  749. irregular and highly confusing, they were also redundant. In avconv the -map
  750. option will create new streams in the output file and map input streams to
  751. them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
  752. each stream in the first input file.
  753. * The -map option now has slightly different and more powerful syntax:
  754. + Colons (':') are used to separate file index/stream type/stream index
  755. instead of dots. Comma (',') is used to separate the sync stream instead
  756. of colon.. This is done for consistency with other options.
  757. + It's possible to specify stream type. E.g. -map 0:a:2 creates an
  758. output stream from the third input audio stream.
  759. + Omitting the stream index now maps all the streams of the given type,
  760. not just the first. E.g. -map 0:s creates output streams for all the
  761. subtitle streams in the first input file.
  762. + Since -map can now match multiple streams, negative mappings were
  763. introduced. Negative mappings disable some streams from an already
  764. defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
  765. all the stream in the first input file, except for the second audio
  766. stream'.
  767. * There is a new option -c (or -codec) for choosing the decoder/encoder to
  768. use, which makes it possible to precisely specify target stream(s) consistently with
  769. other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
  770. libvorbis sets the codec for the first audio stream and -c copy copies all
  771. the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
  772. aliases to -c:v/a/s
  773. * It is now possible to precisely specify which stream should an AVOption
  774. apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
  775. -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
  776. syntax is deprecated and will stop working soon.
  777. * -map_chapters now takes only an input file index and applies to the next
  778. output file. This is consistent with how all the other options work.
  779. * -map_metadata now takes only an input metadata specifier and applies to
  780. the next output file. Output metadata specifier is now part of the option
  781. name, similarly to the AVOptions/map/codec feature above.
  782. * -metadata can now be used to set metadata on streams and chapters, e.g.
  783. -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
  784. This made -vlang/-alang/-slang options redundant, so they were removed.
  785. * -qscale option now uses stream specifiers and applies to all streams, not
  786. just video. I.e. plain -qscale number would now apply to all streams. To get
  787. the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
  788. and -aq is now an alias for -q:a.
  789. * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
  790. uses stream specifiers. Use -bsf:v/a/s instead of the old options.
  791. * -itsscale option now uses stream specifiers, so its argument is only the
  792. scale parameter.
  793. * -intra option was removed, use -g 0 for the same effect.
  794. * -psnr option was removed, use -flags +psnr for the same effect.
  795. * -vf option is now an alias to the new -filter option, which uses stream specifiers.
  796. * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
  797. * -vtag/-atag/-stag options are now aliases to the new -tag option.

  1406. - added decoding codec parameter guessing (.e.g. for MPEG, because the
  1407. header does not include them)
  1408. - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
  1409. play them (only tested video)
  1410. - fixed H.263 white bug

  1412. - add MMX code for polyphase img resample filter

  1417. decoder)
  1418. - added fractional frame rate support
  1419. - codecs are no longer searched by read_header() (should fix ffserver
  1420. segfault)

  1429. - changed the FOURCC code for H.263 to "U263" to be able to see the
  1430. +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
  1431. this +codec ;) (JuanJo).
  1432. - Halfpel motion estimation after MB type selection (JuanJo)
  1433. - added pgm and .Y.U.V output format
  1434. - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
  1435. output.
  1436. - added pgmpipe I/O format (original patch from Martin Aumueller
  1437. <lists at reserv.at>, but changed completely since we use a format
  1438. instead of a protocol)
  1439. version 0.4.2:
  1440. - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
  1441. (for OpenDivX) is almost complete: 8x8 MVs and rounding are
  1442. missing. MSMPEG4 support is complete.
  1443. - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
  1444. can decode ffmpeg MPEGs :-)).
  1445. - added libavcodec API documentation (see apiexample.c).
  1446. - fixed image polyphase bug (the bottom of some images could be
  1447. greenish)
  1448. - added support for non clipped motion vectors (decoding only)
  1449. and image sizes non-multiple of 16
  1450. - added support for AC prediction (decoding only)
  1451. - added file overwrite confirmation (can be disabled with -y)
  1452. - added custom size picture to H.263 using H.263+ (Juanjo)
  1453. version 0.4.1:
  1454. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
  1455. of AVI and ASF to DIV3.
  1456. - added -me option to set motion estimation method
  1457. (default=log). suppressed redundant -hq option.
  1458. - added options -acodec and -vcodec to force a given codec (useful for
  1459. AVI for example)
  1460. - fixed -an option
  1461. - improved dct_quantize speed
  1462. - factorized some motion estimation code
  1463. version 0.4.0:

  1465. multistream support to ffmpeg.
  1466. - added timeshifting support for live feeds (option ?date=xxx in the
  1467. URL)
  1468. - added high quality image resize code with polyphase filter (need
  1469. mmx/see optimization). Enable multiple image size support in ffserver.
  1470. - added multi live feed support in ffserver
  1471. - suppressed master feature from ffserver (it should be done with an
  1472. external program which opens the .ffm url and writes it to another
  1473. ffserver)
  1474. - added preliminary support for video stream parsing (WAV and AVI half
  1475. done). Added proper support for audio/video file conversion in
  1476. ffmpeg.
  1477. - added preliminary support for video file sending from ffserver
  1478. - redesigning I/O subsystem: now using URL based input and output

  1481. - added "tty user interface" to ffmpeg to stop grabbing gracefully
  1482. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)

  1489. - added stereo in MPEG audio encoder
