  641. - openal input device added
  642. - boxblur filter added
  643. - BWF muxer
  644. - Flash Screen Video 2 decoder
  645. - lavfi input device added
  646. - added avconv, which is almost the same for now, except
  647. for a few incompatible changes in the options, which will hopefully make them
  648. easier to use. The changes are:
  649. * The options placement is now strictly enforced! While in theory the
  650. options for ffmpeg should be given in [input options] -i INPUT [output
  651. options] OUTPUT order, in practice it was possible to give output options
  652. before the -i and it mostly worked. Except when it didn't - the behavior was
  653. a bit inconsistent. In avconv, it is not possible to mix input and output
  654. options. All non-global options are reset after an input or output filename.
  655. * All per-file options are now truly per-file - they apply only to the next
  656. input or output file and specifying different values for different files
  657. will now work properly (notably -ss and -t options).
  658. * All per-stream options are now truly per-stream - it is possible to
  659. specify which stream(s) should a given option apply to. See the Stream
  660. specifiers section in the avconv manual for details.
  661. * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
  662. sense that they're specified after the output filename instead of before,
  663. like all other options. In avconv this irregularity is removed, all options
  664. apply to the next input or output file.
  665. * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
  666. irregular and highly confusing, they were also redundant. In avconv the -map
  667. option will create new streams in the output file and map input streams to
  668. them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
  669. each stream in the first input file.
  670. * The -map option now has slightly different and more powerful syntax:
  671. + Colons (':') are used to separate file index/stream type/stream index
  672. instead of dots. Comma (',') is used to separate the sync stream instead
  673. of colon.. This is done for consistency with other options.
  674. + It's possible to specify stream type. E.g. -map 0:a:2 creates an
  675. output stream from the third input audio stream.
  676. + Omitting the stream index now maps all the streams of the given type,
  677. not just the first. E.g. -map 0:s creates output streams for all the
  678. subtitle streams in the first input file.
  679. + Since -map can now match multiple streams, negative mappings were
  680. introduced. Negative mappings disable some streams from an already
  681. defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
  682. all the stream in the first input file, except for the second audio
  683. stream'.
  684. * There is a new option -c (or -codec) for choosing the decoder/encoder to
  685. use, which makes it possible to precisely specify target stream(s) consistently with
  686. other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
  687. libvorbis sets the codec for the first audio stream and -c copy copies all
  688. the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
  689. aliases to -c:v/a/s
  690. * It is now possible to precisely specify which stream should an AVOption
  691. apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
  692. -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
  693. syntax is deprecated and will stop working soon.
  694. * -map_chapters now takes only an input file index and applies to the next
  695. output file. This is consistent with how all the other options work.
  696. * -map_metadata now takes only an input metadata specifier and applies to
  697. the next output file. Output metadata specifier is now part of the option
  698. name, similarly to the AVOptions/map/codec feature above.
  699. * -metadata can now be used to set metadata on streams and chapters, e.g.
  700. -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
  701. This made -vlang/-alang/-slang options redundant, so they were removed.
  702. * -qscale option now uses stream specifiers and applies to all streams, not
  703. just video. I.e. plain -qscale number would now apply to all streams. To get
  704. the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
  705. and -aq is now an alias for -q:a.
  706. * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
  707. uses stream specifiers. Use -bsf:v/a/s instead of the old options.
  708. * -itsscale option now uses stream specifiers, so its argument is only the
  709. scale parameter.
  710. * -intra option was removed, use -g 0 for the same effect.
  711. * -psnr option was removed, use -flags +psnr for the same effect.
  712. * -vf option is now an alias to the new -filter option, which uses stream specifiers.
  713. * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
  714. * -vtag/-atag/-stag options are now aliases to the new -tag option.

  1366. and image sizes non-multiple of 16
  1367. - added support for AC prediction (decoding only)
  1368. - added file overwrite confirmation (can be disabled with -y)
  1369. - added custom size picture to H.263 using H.263+ (Juanjo)
  1370. version 0.4.1:
  1371. - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
  1372. of AVI and ASF to DIV3.
  1373. - added -me option to set motion estimation method
  1374. (default=log). suppressed redundant -hq option.
  1375. - added options -acodec and -vcodec to force a given codec (useful for
  1376. AVI for example)
  1377. - fixed -an option
  1378. - improved dct_quantize speed
  1379. - factorized some motion estimation code
  1380. version 0.4.0:
  1381. - removing grab code from ffserver and moved it to ffmpeg. Added
  1382. multistream support to ffmpeg.
  1383. - added timeshifting support for live feeds (option ?date=xxx in the
  1384. URL)
  1385. - added high quality image resize code with polyphase filter (need
  1386. mmx/see optimization). Enable multiple image size support in ffserver.
  1387. - added multi live feed support in ffserver
  1388. - suppressed master feature from ffserver (it should be done with an
  1389. external program which opens the .ffm url and writes it to another
  1390. ffserver)
  1391. - added preliminary support for video stream parsing (WAV and AVI half
  1392. done). Added proper support for audio/video file conversion in
  1393. ffmpeg.
  1394. - added preliminary support for video file sending from ffserver
  1395. - redesigning I/O subsystem: now using URL based input and output
  1396. (see avio.h)
  1397. - added WAV format support
  1398. - added "tty user interface" to ffmpeg to stop grabbing gracefully
  1399. - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
  1400. (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
  1401. - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
  1402. - added new motion estimation algorithms, log and phods (Juanjo)
  1403. - changed directories: libav for format handling, libavcodec for
  1404. codecs
  1405. version 0.3.4:
  1406. - added stereo in MPEG audio encoder
  1407. version 0.3.3:
  1408. - added 'high quality' mode which use motion vectors. It can be used in
  1409. real time at low resolution.
  1410. - fixed rounding problems which caused quality problems at high
  1411. bitrates and large GOP size
  1412. version 0.3.2: small fixes
  1413. - ASF fixes
  1414. - put_seek bug fix
  1415. version 0.3.1: added avi/divx support
  1416. - added AVI support
  1417. - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
  1418. - added sound for flash format (not tested)
  1419. version 0.3: initial public release
